Caterpillar 115
Maintenance schedule, common problems & OEM parts breakdown
The Cat H115 is a hydraulic hammer, an excavator-mounted work tool for rock breaking and concrete demolition, not a self-powered machine. It has no engine, no undercarriage and no transmission of its own; it runs entirely off the carrier excavator's auxiliary hydraulic circuit, which supplies the flow and pressure that drive the piston. Caterpillar has offered the H115 across three generations: the legacy H115Es (part of the earlier Es-series hammer line), the current H115 S Performance (the general-duty hammer in this weight class), and the H115 GC S (a heavier-duty variant built for continuous, high-cycle work). Working weight spans roughly 1,070-1,460 kg (2,359-3,219 lb) depending on series and mounting bracket, with a 110 mm tool diameter on the Es and S Performance versions and 120 mm on the GC S. All three fit carriers in roughly the 12-20 tonne class (narrower on GC S, around 13-18 tonnes) and need an auxiliary circuit delivering 70-130 L/min (19-34 gpm) at 13,000-17,000 kPa (1,885-2,465 psi), figures that vary by series and by the excavator's own circuit setup. Configurations include standard pin-on or bracket mounting, an optional autolube grease system, and an optional wear package for abrasive sites.
Across generations Caterpillar kept the H115's basic tool-class positioning, a 110-120 mm shank on a 12-20 tonne carrier, while updating the internals. The S Performance line emphasizes faster cycle times and simpler single-point, standing-height greasing. The GC S line adds a larger tool diameter, higher operating pressure and a reinforced housing for sustained demolition and quarry work. Both current lines standardized a slip-fit lower bushing that rotates 90 degrees for a fresh wear face, and both offer factory autolube as an option rather than manual greasing only. On the used and parts market, the H115 matters because bushings, seal kits, pins and tie rods wear out on a predictable schedule regardless of the tool's age, so parts demand for this platform holds steady long after new-unit sales shift to newer models. Used H115Es and early S Performance units remain common on rental and secondhand excavator lots, and because the tool shares its shank size and mounting envelope with other hammers in its weight class, buyers can often source compatible wear bushings, pins and seal kits even after Caterpillar moves the catalog listing to a newer generation.

Caterpillar 115 specifications
Tool specifications
| Identity | Caterpillar 115 (category: work tool) refers to the Cat H115 hydraulic hammer, an excavator-mounted breaker attachment. It is produced across several generations/series: legacy H115Es, current H115 S Performance, and heavy-duty H115 GC S. It is not a self-powered machine and has no engine, mast, or driveline of its own. |
| Working (operating) weight | Varies by series. H115 S Performance / H115Es: approx. 1,070-1,460 kg (2,359-3,219 lb). H115 GC S (heavier-duty variant): minimum published operating weight 1,405 kg (3,098 lb); maximum not published in available spec sheets. |
| Tool (chisel) shaft diameter | Varies by series. H115 S Performance / H115Es: approx. 110 mm (4.3 in). H115 GC S: 120 mm (4.7 in). |
| Impact energy class | Approx. 3,000 J (approx. 2,212 ft-lb) impact energy class reported for the H115 GC S. Only single-source confirmation found; treat as approximate and verify against the current Cat spec sheet for your specific unit. |
| Blow (impact) frequency range | Varies by series. H115 S Performance / H115Es: 370-800 blows per minute. H115 GC S: 450-800 blows per minute. |
| Overall length | Approx. 1,683 mm (66.3 in) total length, reported for the H115Es (legacy) generation. Not separately published for the H115 S Performance or H115 GC S variants in the sources reviewed; use as an approximate reference only and confirm against the specific series spec sheet. |
Carrier requirements
| Recommended carrier (excavator) weight class | Varies by series. H115 S Performance / H115Es: 12-20 t (26,500-44,100 lb) carrier operating weight. H115 GC S: 13-18 t (28,660-39,683 lb) carrier operating weight. |
| Required hydraulic flow | Varies by series. H115 S Performance / H115Es: 70-130 L/min (19-34 gpm). H115 GC S: 90-120 L/min (24-32 gpm). |
| Required operating pressure | Varies by series and by source. H115 S Performance / H115Es: approx. 13,000-15,000 kPa (1,885-2,175 psi), with at least one dealer listing up to 16,000 kPa (2,321 psi) at the high end. H115 GC S: 15,000-17,000 kPa (2,175-2,465 psi). |
Dimensions
| Overall length | Approx. 1,683 mm (66.3 in), reported for the H115Es generation; treat as approximate for related series pending confirmation from the current series spec sheet. |
| Width | Not published in the sources reviewed. Verify against the Cat spec sheet for the specific series/generation. |
| Tool diameter | 110 mm (4.3 in) on H115 S Performance / H115Es; 120 mm (4.7 in) on H115 GC S. |
| Shipping/transport dimensions | Not published in the sources reviewed. |
Performance
| Impact (blow) rate range | 370-800 bpm on H115 S Performance / H115Es; 450-800 bpm on H115 GC S (higher minimum rate on the GC S variant). |
| Series/generation differences | Three generations are marketed under the H115 designation: legacy H115Es, current H115 S Performance (general-duty, oil-charged accumulator design intended to reduce routine gas-charge checks per the manufacturer's own product description), and H115 GC S (heavier tool diameter, higher operating pressure range, and a gas-charge check port accessible with the hammer still mounted on the carrier, per the manufacturer's own product description). Confirm which series a given unit belongs to before applying any single spec value. |
| Carrier weight class comparison | H115 S Performance covers a broader/lighter carrier range (12-20 t) while H115 GC S targets a narrower, heavier-duty range (13-18 t), consistent with its larger 120 mm tool diameter and higher operating pressure. |
Service capacities (summary)
| Nitrogen accumulator precharge | Not published in any source reviewed for the H115 (any series). Precharge specs for hydraulic hammers commonly vary by series and by individual unit; do not assume a figure from another hammer model. Verify against the dealer's technical service manual or by direct dealer inquiry for the specific series/serial number. |
| Grease/lube spec (by name only) | Cat Hydraulic Hammer Paste, a copper-graphite chisel paste, is the named lubricant for chisel/bushing contact areas on Cat hydraulic hammers including the H115 series. No capacity or interval figures are asserted here; consult the service manual for application interval. |
Values vary by configuration, region, and serial range — confirm against your machine before planning transport or lifts.
115 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase, cooling system, fuel tank, transmission/powertrain, final drives, axles/differentials | Not applicable | The 115 is a Cat hydraulic hammer work tool (covers the H115E S generation sharing an OMM with the H110E S/H120E S/H130E S/H140E S/H160E S/H180E S family, plus later H115 S Performance and H115 GC S silenced versions). It is not a self-powered machine — it carries no engine, cooling system, fuel tank, transmission, final drive, or axle of its own. It mounts on a carrier excavator or backhoe-loader and draws all hydraulic flow from that carrier. For these systems, consult the carrier machine's own fluids chart, not the hammer's OMM. |
| Hydraulic system (hammer has no onboard tank; runs on carrier supply) | No dedicated hammer reservoir. Flow and pressure must be matched to the carrier: roughly 70 to 130 L/min (19 to 34 US gpm) at 13000 to 15000 kPa (1885 to 2175 psi) for the 115-class hammer, exact figures vary by series/generation — confirm against the specific 115 variant's spec sheet | Use the carrier's specified hydraulic oil — Cat HYDO Advanced, Cat TDTO, or Cat BIO HYDO/HEES where a biodegradable fluid is called for. Caterpillar guidance for any machine fitted with a hydraulic hammer: do not run SAE 0W or SAE 5W viscosity-grade hydraulic oil, since hammer duty cycles push oil temperature and shear load higher than normal digging duty. Pick carrier oil grade by climate per the carrier's own viscosity-versus-temperature chart, not the hammer's. |
| Tool/chisel lubrication (grease) | No fixed fill capacity — grease is dosed per grease point, not filled to a level. Manual greasing interval runs every 2 to 4 hours of hammer operation (twice-daily minimum), about 10 to 15 gun strokes to the tool bushing and tool per interval, up to 20 strokes on larger tool diameters. Where an automatic lubrication system is fitted, it feeds from a paste cartridge sized around 400 g (about 0.14 US gal / 0.4 L) per cartridge, replaced as consumed rather than topped up | Cat Hydraulic Hammer Paste only — an aluminum-complex-thickened NLGI Grade 2 paste fortified with copper and graphite, rated to hold up under the extreme heat and shock loading at the tool-to-bushing interface. One paste spec year-round; Caterpillar does not publish a separate winter/summer grade for hammer paste the way it does for chassis grease. Do not substitute ordinary chassis or multipurpose grease — it breaks down under hammer impact heat and accelerates bushing wear. |
| Accumulator (gas precharge) | Not a fluid or lubricant — dry nitrogen gas charge; precharge pressure is set per hammer series/generation | Dry nitrogen only, never oil or another gas. Precharge value differs by 115 variant and generation — verify the correct setting with a Cat dealer or the specific unit's OMM before servicing; do not treat this as a serviceable oil/grease point. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the 115 beyond the schedule
Predictive Maintenance & Fluid Analysis
The H115 has no engine oil to sample, so predictive maintenance centers on the carrier's hydraulic oil and the hammer's grease. Pull a hydraulic oil sample from the excavator's auxiliary circuit at the same interval as the machine's own hydraulic service, since the hammer's high-pressure impact cycle pushes fine contamination and heat through that circuit faster than digging work does. Watch particulate counts and water content. Check grease condition and auto-lube reservoir level regularly, since dry or contaminated grease is the leading driver of accelerated bushing and pin wear.
Corrective & Common Repairs
Most H115 repairs trace back to the lower bushing, tool pin and seal set. Expect bushing wear or side play in the tool shank first, especially on abrasive rock; rotate the slip-fit lower bushing 90 degrees before replacing it outright. Blank-firing (running the tool without ground contact) is a common operator-error failure that scores the piston nose and cylinder bore, so check tool retention and down-sensing regularly. A leaking rod area or a soft-hitting hammer usually points to the piston seal set or a fading nitrogen charge in the accumulator, not the carrier's pump.
Overhaul & Rebuild Points
A full H115 rebuild centers on the piston, cylinder bore and accumulator. At major overhaul, measure the cylinder bore and piston for scoring or step wear from blank-fire events or worn bushings, since a scored bore is the usual reason a tool gets rebuilt rather than reseal-and-return. Service the nitrogen accumulator diaphragm alongside the seal kit rather than separately. Replace upper and lower bushings, tie rods and through-bolts as a matched set at rebuild, since mixing worn and new wear parts on the same tool accelerates the next failure.
Seasonal & Environment Servicing
In cold weather, nitrogen precharge pressure drops with ambient temperature, so recheck and top up the accumulator charge before winter use or the hammer will short-stroke and lose impact energy. In hot climates or continuous production breaking, derate the duty cycle and watch carrier hydraulic oil temperature, since sustained high-pressure cycling on the H115 heats the circuit faster than excavation work. On abrasive quarry or demolition sites, expect faster bushing and pin wear; step up inspection frequency and consider the optional wear package rather than waiting for the standard interval.
115 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| No electronic fault code (mechanical work tool) | The H115 hammer is a hydromechanical attachment with no onboard engine, ECM, or controller of its own, so it has no CID/FMI, SPN/FMI, or MID-style diagnostic trouble code list. | Design intent: the tool is powered entirely by the carrier excavator's auxiliary hydraulic circuit with no dedicated hammer electronics. | Do not expect a scan-tool code from the hammer; diagnose using visual checks and the carrier's own instrumentation instead. |
| Auto-lube reservoir low (sight gauge, not a displayed code) | The standard onboard autolube reservoir that continuously greases the tool/bushing area has dropped below usable level. | Reservoir not topped off at the service interval, or a blocked/leaking grease feed line. | Check the grease reservoir sight level before operation, refill with the specified grease, and inspect the feed line for blockage or leaks. |
| Blank-fire / over-stroke shutoff response (hydraulic behavior, no lamp code) | The tool stops cycling when it senses no resistance under the tip, a built-in protection against firing with the tool off the work face. | Operator holding the trigger with the tool lifted off material, or a fault in the retract-sensing valve or linkage. | Reposition the tool firmly against the work face first; if cycling still fails to resume, inspect the retract-sensing valve/linkage per the operation and maintenance manual. |
| Accumulator pre-charge low (gauge reading at charging port, not a display code) | Nitrogen pre-charge in the hydraulic accumulator has fallen off spec, reducing impact smoothing and energy transfer. | Gradual nitrogen loss over time, worn charging valve seal, or a slow gas leak. | Check pre-charge pressure against the specified value using a nitrogen charging kit at the scheduled interval, and recharge or reseal as needed. |
| Carrier auxiliary hydraulic circuit fault (excavator's own code, not hammer-specific) | Insufficient or excessive flow/pressure to the hammer circuit can trip a fault on the carrier excavator's own monitor; this originates from the carrier, not the H115 itself. | Auxiliary flow or pressure setting on the carrier not matched to the H115 line's specified range, a quick-disconnect coupler not fully seated, or a carrier relief-valve issue. | Confirm the carrier's auxiliary circuit is set to the flow/pressure range specified for the H115 model, verify couplers are fully engaged, and reference the carrier's own fault code list for the code shown. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
115 attachments & work tools
Tool point options
The 115-class hammer ships with a choice of working tool: moil point, chisel, blunt, super blunt, or pyramidal, selected by application (rock breaking, concrete demolition, trenching, secondary breaking). Tool diameter for this size class runs about 110 mm (4.3 in); tools are field-swappable through the retaining pin arrangement without removing the hammer from the carrier.
Carrier weight class
This hammer size is matched to excavators in roughly the 12-20 t (26,000-44,000 lb) class, varying slightly by series (GC vs Performance vs E-series). Working weight of the hammer itself runs approximately 1,400-1,500 kg (3,100-3,300 lb) including bracket.
Mounting / bracket system
Standard mounting is a box-type through-bracket (top bracket) fitted between the stick and tool, matched to the host excavator's stick and link geometry by the dealer at time of sale. Bracket style differs slightly between the Performance/S line and the E-series line, so brackets are not directly interchangeable across series.
Hydraulic kit requirements
The carrier needs an auxiliary one-way hydraulic circuit sized to the hammer's operating window, roughly 70-130 l/min flow (varies by source and series) at an operating pressure in the 150-160 bar range. Machines not pre-plumbed for a hammer need an installed auxiliary kit: control valve, in-cab pedal or joystick button, and hoses routed to the stick end, sized to the hammer's rated flow and pressure.
Series / factory configurations
Offered in parallel lines for this size: GC S (value/durability-focused, simple design, factory silenced), S Performance (adjustable piston speed with high-speed and max-power modes, automatic blank-fire shutoff, oil-fired accumulator design), and an older E-series equivalent. All current lines carry the "S" designation for standard noise suppression suitable for regulated or residential job sites.
Maintenance and guarding features
Current-production hammers in this class include an internal buffering system for vibration and noise reduction, a slip-fit 90-degree rotatable lower bushing for field service, and standard on-board autolube for continuous tool greasing. These reduce daily service tasks versus manual-grease legacy models.

115 serial number reference
On Cat hydraulic hammers, the PIN/serial plate is mounted on the top bracket or upper housing of the power cell, near where the hammer bolts to the excavator's stick linkage; on enclosed/silenced models it may sit under a housing panel. The plate stamps a 3-letter serial number prefix followed by a numeric sequence. The prefix identifies the exact hammer model and configuration (standard vs ES/silenced vs GC vs GC silenced); the digits that follow are the individual unit count within that prefix run. Note that a single model can carry two different documented prefixes at once (a running production change), so match on the model name printed on the housing decal, not the prefix alone, when in doubt.
| Prefix | Identifies | Notes |
|---|---|---|
| HWL | H115 S (Performance Hammer, standard) | Current-production Cat Performance Hammer. Matched to excavators in the 12-20 t (26,500-44,100 lb) operating weight class. Hydraulic breaker work tool powered by the carrier's hydraulic system, no onboard engine. Shares the same power-cell design as the H115ES; tool, bushing, seal-kit and tie-rod references are identical between the two. |
| HHD | H115ES (Performance Hammer, enclosed/silenced) | Enclosed/silenced counterpart to the H115 S, built on the same power-cell design and sharing identical tool, bushing, seal-kit and tie-rod references. Same 12-20 t (26,500-44,100 lb) carrier weight class as the H115 S. Documented alongside the S line in Cat's Performance Hammer literature; current Performance Hammer marketing emphasizes the S designation, so confirm present-day dealer availability of new ES units. |
| KSM | H115GC (GC Hammer, non-silenced) | Separate GC Hammer family with its own parts reference guide, distinct from the Performance Hammers line. Non-silenced, standard-housing configuration. Its silenced sibling, the H115GC S, is matched to 13-18 t (28,660-39,683 lb) carriers; the non-silenced H115GC's own carrier range was not separately published, confirm with dealer. |
| HHW | H115GC S (GC Silenced Hammer) | Silenced/enclosed version of the H115GC, matched to 13-18 t (28,660-39,683 lb) carriers. Two serial prefixes are documented for this same model in the factory parts guide, with matching part references across every component category (tools, bushings, seal kit, buffers, wear plates, tie rods). Treat as a running production change rather than a configuration difference; confirm which prefix applies to a given unit with the dealer. |
| K8M | H115GC S (GC Silenced Hammer) | Second documented prefix for the identical H115GC S model. Every component reference (tools, bushings, seal kit, buffers, wear plates, tie rods) matches the HHW line item for item in the factory parts guide. Treat as an alternate/later prefix for the same model rather than a different configuration; confirm with dealer if precision matters. |
Frequently asked questions
What carrier and hydraulic requirements does the H115 need?
The H115 fits excavators in roughly the 12-20 tonne class (narrower on GC S, around 13-18 tonnes) and needs an auxiliary hydraulic circuit delivering 70-130 L/min at 13,000-17,000 kPa (1,885-2,465 psi). Exact flow and pressure targets vary by series, so match the hammer to the carrier's actual auxiliary circuit output before fitting.
What is the H115's operating weight?
Working weight runs roughly 1,070-1,460 kg (2,359-3,219 lb) depending on series and mounting bracket, lightest on the H115 S Performance and heaviest on the H115 GC S.
What replaced the H115?
Nothing has fully replaced it; Caterpillar currently sells two parallel lines in this class, the H115 S Performance and the heavier-duty H115 GC S, both descended from the earlier H115Es. The S Performance covers general-duty breaking and the GC S is the reinforced, larger-tool option for continuous high-cycle work.
What 115 owners discuss
What's the number one wear complaint owners have with an H115-class hammer?
Lower bushing wear, hands down. The lower bushing keeps the tool centered against the piston and cylinder bore, and it absorbs side-load whenever the tool is angled, twisted, or used to pry. Field experience puts lower bushing life around 200-500 hours depending on application and grease discipline, with the upper bushing usually lasting longer. The rotatable lower bushing design (turn it 90 degrees for a fresh wear face) buys extra service life before replacement, but skipping the roughly 100-hour bushing check is the fastest way to end up with an off-angle strike that cracks a chisel. Have your dealer verify bushing clearance against spec before the tool goes back into hard service.
How much play in the bushings or tool pins is too much?
Any play you can feel by hand-rocking the tool with the hammer off is worth investigating. Loose bushings let the tool strike at a slight angle, which bends the tool and stresses the pins that retain it, and hammered-out or bent retainer pins are a classic sign of accumulated blank-firing rather than normal wear. Left unchecked, excess bushing clearance turns into scored piston and cylinder surfaces, which is a far more expensive repair than a bushing swap. Have your dealer verify pin and bushing tolerances rather than eyeballing it, since a tool ejection from a badly worn front head is a real safety hazard.
Does the H115 still need the nitrogen gas-charge checks older breakers required?
Depends on which internal design is under the housing. Older-style breakers ran an externally charged nitrogen accumulator inline with the supply hose, and a slow leak-down there is the classic explanation for "the hammer doesn't hit like it used to." Cat's H115 S line moved to an oil-fired (oil-cushioned) internal design specifically to take routine gas-charge checks off the maintenance list, though a technician can still verify charge condition without pulling the tool off the carrier if performance drops. Don't assume every used H115 on a lot has this design, confirm which internal setup is fitted before skipping the gas-charge inspection. Have your dealer verify accumulator condition before you rely on it for a full shift.
What flow and pressure mistakes actually damage the hammer?
Feeding it more oil than it's rated for. An H115-class tool typically wants roughly 70-130 L/min (18-34 gpm) at around 150-160 bar (2,175-2,320 psi), and running above that spec makes the piston cycle faster than the design tolerates. Overspeed impacts beat up internal parts, transmit shock back through the stick and boom, and accelerate wear on pins, bushings, and the mounting bracket, and can also blow seals. A commonly repeated rule of thumb is to keep breaker flow demand at roughly half the carrier's rated auxiliary flow ceiling rather than running near the carrier's maximum. Anyone swapping the hammer between carriers should recheck the relief valve and flow setting instead of assuming the previous machine's setup carries over. Have your dealer verify carrier flow and pressure match H115 spec before extended use.
What do owners say about the auto-greasing (autolube) system?
Reviews are mixed but mostly practical. When kept filled, the autolube reservoir maintains a steady grease film between bushing and tool shank and meaningfully extends bushing life over hand-greasing. The recurring complaint, especially on rental or multi-operator fleets, is that nobody keeps the reservoir topped off, and once dust and dirt stick to the grease residue around the fitting, that contaminated mix gets pulled back into the system and acts like a lapping compound instead of a lubricant. A dry autolube system is often worse than none at all because crews stop manual greasing once they see the fitting is there. Units without a grease-out lockout feature need the reservoir physically checked on a set interval rather than trusting a sight gauge.
What operator habits show up most often in H115 failure reports?
Blank firing, by a wide margin. Triggering the hammer before the tool is seated firmly on the material, or continuing to fire through breakthrough, sends the piston's impact energy back through the tool, bushings, and housing instead of into the work. That habit is named repeatedly as the root cause behind chipped pistons, cracked chuck housings near weld areas, and bent retainer pins. Close behind it is using the tool bit as a pry bar or lever, since the hammer is built for straight vertical impact and side-loading the chisel snaps tools and scores bushings even on an otherwise well-maintained unit. Contaminated or wrong-viscosity hydraulic oil is the other common thread, since it degrades the internal seals faster than normal wear would.
What should a buyer check before purchasing a used H115?
The same short list comes up again and again: grab the tool and check for bushing play with the hammer shut down (looseness means the lower bushing is near end of life and the piston bore may already be scored); inspect the tool pin and retainer for bending or hammering, a sign of past blank firing; verify the accumulator or gas-charge condition, since a weak charge shows up as sluggish, uneven blows even with correct carrier flow; check the housing and chuck area, particularly around weld repairs and the mounting bracket, for cracks from vibration and boom stress; and look for oil weeping around the piston seal area. Running the hammer under load, if the seller allows it, is the standard way to confirm blow rate and power before money changes hands. Have your dealer verify bushing clearance, accumulator charge, and housing integrity against factory spec before you buy.
