Caterpillar H115S
Maintenance schedule, common problems & OEM parts breakdown
The Cat H115S is a hydraulic hammer in Caterpillar's S/Performance Hammer trim, a passive work tool with no engine of its own that runs entirely off a carrier excavator's one-way auxiliary hydraulic circuit. It mounts on 12-20 t (26,500-44,100 lb) class excavators, roughly the Cat 320-330 range, with an operating weight of about 1,070-1,460 kg (2,360-3,220 lb) depending on tool and configuration, and an impact energy class near 4,070 J (3,000 ft-lbf) with a tool shaft diameter around 110 mm (4.3 in). Tool options include moil, chisel, blunt, pyramidal, and super blunt points for different rock-breaking and demolition work. Within Cat's current hammer lineup the H115S sits alongside the value-focused H115 GC S and the wider Performance Hammer size range running from H120S up through H180S and H195, all built around the same platform and sharing common service practice.
In the used and parts market, wear items drive most of the ownership cost on this tool: the tool bushing, tie rods, and tool pin wear fastest and are the parts most often replaced or rebuilt. Matching carrier hydraulic flow (about 70-130 L/min at 13,000-15,000 kPa, varies by configuration) to the hammer matters: an undersized or oversized carrier circuit accelerates wear or starves the hammer of power. Serial/PIN identification matters because the H115S shares one parts book across the H115S/H120S/H130S/H180S/H195 size range, and because Cat's naming moved from the legacy plain "115" designation to "H115S" partway through the same production run; getting the right prefix keeps parts orders and wear-spec checks tied to the correct size class. When buying used, check for blank-fire damage, bushing clearance, and accumulator condition before relying on the unit for production work.

H115S fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Tool bushing / tie-rod grease point (manual) | Single grease point at the front head, marked by a grease decal; Cat lists it as a daily check/greasing point. General hydraulic-hammer field guidance (not H115S-specific) calls for roughly 10-15 gun strokes about every 2 hours of hammer operating time, more often in severe duty, if no autolube is fitted — exact interval varies by application/source. | Cat Hydraulic Hammer Paste — copper-and-graphite paste formulated for the tool/bushing wear surfaces, supplied in 400 g (14 oz) cartridges. No separate hot/cold-climate grade is published for this tool. |
| Automatic lubrication system (optional, hammer-mounted or carrier-mounted) | Hammer-mounted units run on a 400 g (14 oz) grease cartridge; carrier-mounted systems draw from a shared reservoir on the host excavator whose size is set by the carrier, not published in the hammer OMM. Verify cartridge or reservoir level before starting work; the system feeds grease to the tool bushing continuously while the hammer runs. | Cat Hydraulic Hammer Paste (copper/graphite), same formulation used at the manual grease point. |
| Accumulator nitrogen pre-charge | Factory-set pre-charge. Cat states the hammer's design keeps gas pressure steady through the annual service interval, so no routine field checks are needed; nitrogen level is only checked/recharged at the annual service, through the hammer's integral charging valve, without removing the hammer from the carrier. Exact pre-charge pressure (kPa/bar) for this tool is not published in the sources reviewed. | Dry nitrogen (N2) gas only — never air, oxygen, or another gas (explosion hazard). No brand-name product applies; charge to the value given on the hammer's data plate/OMM at the annual check. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the H115S beyond the schedule
Predictive Maintenance & Wear Analysis
The H115S has no oil to sample, so predictive care means inspection trends, not fluid analysis. Track grease seepage at the tool bushing, a stopped ring of paste signals bushing wear before failure. Log tie-rod torque readings over successive checks to catch progressive loosening. Watch for metal particulate in spent grease, a sign of advancing bushing or pin wear. Falling blows-per-minute or a shortening stroke flags internal wear before a breakdown, and drifting carrier flow or pressure readings can predict hose, filter, or pump problems reaching the hammer.
Corrective & Common Repairs
Bushing and tie-rod wear drive most corrective work on the H115S. Replace or rotate the front bushing once clearance exceeds spec, and retorque or replace stretched tie rods before they let the housing shift under impact. Worn or mushroomed tool pins and retainers need replacement to stop tool rattle and cracking. If grease seepage stops between checks, address the bushing immediately rather than waiting for the interval. Blank-firing, running the hammer without ground contact, remains the most common cause of cracked tools and premature bushing failure.
Overhaul & Rebuild Points
A full teardown inspects the piston and cylinder bore for wear, since scoring there causes weak or erratic impact. Seal set and diaphragm replacement follows the factory interval of roughly 1000 hours or one year, whichever comes first. Rebuild also covers front-head bushing renewal, backhead and valve component inspection, and tie-rod retorque to spec on reassembly. In practice, a rebuild is usually triggered by symptoms rather than the calendar: falling impact energy, excessive backhead heat, or a short or erratic stroke all point to internal wear needing teardown.
Seasonal & Environment Servicing
Cold weather contracts the nitrogen charge and drops accumulator pressure, so check precharge condition before winter work and again at the annual inspection through the hammer's integral charging valve. Abrasive, dusty sites such as quarry rock and concrete demolition accelerate bushing and tool wear, so shorten grease and bushing-clearance checks on those jobs. Wet or muddy sites push grit into the tool bushing and mounting bolts faster, so check tie-rod tension and bracket bolts more often in those conditions. Store the hammer with the tool retracted and protected between jobs.
H115S fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Hammer will not cycle | Tool does not begin percussion when the operator engages the carrier's auxiliary/hammer circuit | Carrier auxiliary shutoff valves not fully open, quick-disconnect couplers not fully seated, or trapped air in the supply/return lines | Confirm carrier auxiliary shutoff valves are fully open and couplers are fully engaged; bleed trapped air by slightly loosening a fitting while briefly cycling the tool, then retighten |
| Piston strikes but produces little or no breaking force (weak impact) | Hammer cycles normally but striking energy is greatly reduced | Nitrogen precharge in the accumulator/backhead has leaked down, reducing the stored energy driving the piston | Check backhead nitrogen charge pressure with a gauge against the operation and maintenance manual spec and recharge as needed; inspect accumulator seals if pressure will not hold |
| Supply hoses bounce or surge excessively during operation | Visible hose movement/pulsation, usually paired with reduced striking force | Same low nitrogen precharge condition as weak-impact symptom, or loose/leaking tube fittings amplifying pressure pulsation | Inspect and tighten hose and tube connections, then verify and recharge nitrogen pressure per spec |
| Excessive heat buildup at the tool or backhead during sustained use | Hammer or hydraulic oil runs hot after continuous operation in one location | Dwelling too long on one point or taking too large a bite, causing the tool to drill rather than penetrate, or a restricted/closed carrier return line raising backpressure | Reposition the tool if no progress is made within a few seconds of striking, reduce bite size, confirm the carrier return line/valve is fully open, and allow the system to cool before resuming |
| Erratic or shortened piston stroke | Percussion cycle becomes inconsistent or the piston does not complete a full stroke | Contamination or sticking in the tool's internal control/valve components, or carrier auxiliary flow and pressure supplied outside the hammer's rated range, including reversed feed/return routing | Verify carrier auxiliary hydraulic flow and pressure match the hammer's rated values and that feed/return lines are connected correctly; if in range, inspect the internal control valve for contamination |
| Visible hydraulic leakage at the tool/bushing area | Fluid seepage around the lower bushing or between piston and cylinder | Excessive wear clearance between the demolition tool and lower bushing, or seal damage from insufficient lubrication | Check tool-to-bushing clearance against spec daily, apply the specified chisel paste or hammer grease, and inspect the piston/cylinder bore for scoring if leakage persists |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
H115S attachments & work tools
Compatible Carrier Excavators
Rated for carriers in the 12-20 t (26,500-44,100 lb) operating weight class, which spans the Cat 320-330 size range (320/320 GC, 323, 330 GC and similar mono-boom or wheeled excavators of that class). Exact fitment on a given carrier still depends on that carrier's stick geometry and hydraulic package, so match against the carrier's own hammer compatibility chart before ordering.
Mounting Bracket / Pin Arrangement
Attaches to the carrier stick with a pin-on top mounting bracket sized to the hammer's 12-20 t carrier class; pin diameter and pin-center spacing are matched to the specific carrier model rather than being a universal fit, so the bracket is ordered against the host machine's linkage, not the hammer alone.
Tool / Moil Options
Offered with Moil, Chisel, and Blunt tool points as the core selection. Moil suits soft, non-abrasive rock and concrete where shaping is not required; Chisel suits sedimentary or weak metamorphic rock and concrete needing medium penetration; Blunt suits igneous or tough metamorphic rock and secondary breaking where the tool should not penetrate. Pyramidal and Super Blunt variants are also cataloged for this Performance Hammer size range.
Carrier Hydraulic Kit / Requirements
Needs a one-way (single-direction) auxiliary hydraulic circuit on the carrier, not the bidirectional circuit used for shears or crushers, delivering 70-130 L/min (19-34 gpm) at an operating pressure in roughly the 13,000-15,000 kPa (1,885-2,175 psi) range; the carrier's auxiliary relief valve must be set within that band. The hammer's own pressure-dampening accumulator is built into the hammer itself and is not a carrier-side component.

H115S serial number reference
The H115S carries its own serial/PIN plate mounted on the hammer body (top of the power cell housing), entirely separate from the carrier excavator's own PIN plate on the machine frame -- always read the tool's own plate when ordering hammer parts, not the carrier's. The plate shows a 3-character prefix followed by a sequential unit number (for example 4PL00214); the prefix ties the unit to a parts-book serial-number break, and the digits place it within that break.
| Prefix | Identifies | Notes |
|---|---|---|
| 4PL | H115S hydraulic hammer | Dedicated prefix for this size within the hammer's shared multi-size parts book (covers 115/H115S through 180/H180S and H195, each size on its own prefix -- 120/H120S/H120CS and 130/H130S each confirmed on a different, distinct prefix). Early units in this run were catalogued under the plain "115" designation; a later running change re-labeled the same continuous production run "H115S" -- same naming-update pattern seen on the related "130"-to-H130S hammer. Confirm the exact plain-115-to-H115S changeover unit number with a dealer before using it for parts fitment; the 4PL prefix itself for this size is solidly corroborated. |
Frequently asked questions
What carrier excavator size does the Cat H115S need?
The H115S is built for 12-20 t (26,500-44,100 lb) class excavators, roughly the Cat 320-330 range. It needs a one-way (unidirectional) auxiliary hydraulic circuit of about 70-130 L/min at 13,000-15,000 kPa; exact flow and pressure targets vary by carrier and hammer configuration, so confirm against the OMM for your combination.
What is the H115S's impact energy class and operating weight?
Impact energy class runs around 4,070 J (3,000 ft-lbf). Operating weight is about 1,070-1,460 kg (2,360-3,220 lb) depending on tool point and mounting configuration.
What replaces the H115S in Caterpillar's current hammer lineup?
No distinct successor model number is documented. The H115S is Caterpillar's current S/Performance Hammer trim at this size, sold alongside the value-oriented H115 GC S; the two trims coexist in the current lineup rather than one replacing the other. Check with your Cat dealer for the latest lineup before assuming a change.
What H115S owners discuss
What wears out first on an H115S, and how do I know it's due for attention?
The lower bushing and the tool/moil bore are first to show play. The lower bushing is slip-fit and can be rotated 90 degrees once to buy extra service life before replacement becomes unavoidable. Tie rods run the full length of the housing and hold backhead, cylinder, and chuck/tool holder in alignment; if one stretches or loosens, the stack can shift and the piston starts binding in the bore instead of firing straight. Any tool bushing play beyond what the service manual allows, or a tie rod that has gone slack, means teardown before more damage spreads downstream. Have your dealer verify tie rod tension and bushing clearance against spec before returning the hammer to service.
What carrier size and hydraulic flow does the H115S actually need?
It is built for excavators in roughly the 12-20 metric ton class, though dealer spec sheets are not perfectly consistent on the exact min/max carrier weight, so confirm the current sheet for your specific unit rather than assuming. Rated flow is generally in the 19-34 gpm (70-130 L/min) range at an operating pressure somewhere around 1900-2500 psi (13,000-17,000 kPa); some literature narrows that window further. Match the hammer to a carrier's auxiliary circuit output before hookup, not just to carrier weight class. An undersized carrier can't hold the tool loaded hard enough, inviting blank firing; an oversized or over-pressured circuit can push the hammer past its rated cycle rate and beat up the internals. Flow-test the circuit before first use rather than assuming the carrier's rated output matches the hammer's window.
Do I still need to grease it by hand if it has autolube?
The onboard autolube feeds the lower bushing continuously while the hammer cycles, but it is not maintenance-free. Cartridge level, feed rate, and trapped air in the line still need checking, and the line should be purged after every cartridge change to confirm grease is actually reaching the bushing before trusting it unattended. If the system runs dry or air-locks unnoticed, the lower bushing and tool shank gall and wear far faster than normal, and that wear transfers straight into the piston bore. In dusty or high-cycle work, topping off manually between cartridge changes is common practice rather than relying on the system alone.
What causes blank-firing damage and how do you avoid it?
Blank firing is cycling the piston with the tool tip not loaded against material, so there is no resistance to absorb the impact and the energy slams straight into the tool, bushing, and backhead. Auto shutoff is built to sense a lost-load condition and stop the piston, but it should not be treated as a substitute for technique. Keep steady downforce on the tool and stop cycling the instant material breaks through, instead of continuing to fire in open air or letting the hammer auto-cycle while repositioning. Repeated blank firing shows up later as stretched or snapped tie rods, cracked bushings, and backhead cracking from the housing absorbing impacts it was not designed to take. Any moment where the tool broke through and kept firing counts as wear, not a non-event.
How do you know the nitrogen accumulator needs attention?
The gas charge absorbs pressure spikes and helps drive stroke energy. When it runs low, the supply hose visibly bounces or hops under pressure and the hammer loses striking power even though flow and pressure at the carrier check out fine. Charge is checked with a nitrogen-specific gauge and topped up with dry nitrogen only, never shop air or oxygen, to the precharge called out in the hammer's service literature. One advantage of this platform is the accumulator can be checked and charged with the hammer still mounted on the carrier, so there is little reason to defer it. Treat charging as at least an annual check, sooner if hose bounce or a drop in power shows up. Have your dealer verify precharge pressure with the correct gauge and fitting before returning the hammer to service.
The piston cycles but the hammer won't strike or feels weak. What's usually going on?
Work through the common causes in order: a low or lost nitrogen charge in the accumulator, since the piston can't build stroke energy without it; a control valve spool sticking or gummed up with contamination; a broken or loosened tie rod letting the internal stack shift and bind; or supply flow/pressure at the carrier falling outside the hammer's rated window. Check that quick couplers are fully seated and the carrier's auxiliary shutoff valve is wide open first, since that is the easiest fix. Also rule out a partially closed return line, which backs pressure into the case, runs the unit hot, and cooks seals over time even before the strike goes weak. Have a qualified hammer tech confirm valve and accumulator condition before a full teardown.
What should you check before buying a used H115S?
Check tool/moil bushing play first. Excessive clearance at the lower bushing is the leading driver of piston and cylinder bore damage, so looseness there is a direct read on remaining life. Look over tie rod tightness and inspect the housing and backhead for cracks, then check every hose, coupler, and the autolube line for leaks or dried-out fittings. Ask for service history, specifically whether the accumulator has been recharged on schedule and whether the unit has a history of running dry or blank firing. If possible, mount it on a compatible carrier and run it under real material contact before buying; a hammer that won't demonstrate a clean, full-power stroke under load is telling you something a walk-around can't. Have your dealer or a qualified hammer tech inspect bushing clearance and tie rod condition before committing, especially on higher-hour units.
