The Caterpillar P115 is not a standalone machine — it is the smallest model in Cat's legacy mechanical pulverizer family (P115, P120, P130, P140), a passive demolition jaw work tool pin-mounted to a hydraulic excavator's stick and linkage. It has no engine, ECM, transmission, undercarriage, or fluid system of its own; the jaw closes off the host carrier's own hydraulic circuit, delivering roughly 96 short tons (850 kN) of force at the throat through an 800 mm (about 31.5-32 in) jaw opening. No factory operating-weight figure has surfaced in available catalog literature, though field listings put an unmounted P115 near 850 kg (about 1,870 lb). It was cataloged across four confirmed production build series — serial prefixes ADM, AEK, AFP, and AGX — sized progressively for 318C/320/324D-class carriers up through 330D/345C/350/365/375-class machines as Cat's excavator lineup moved through several generations, with mounting kits offered per carrier and per linkage code (b, c, g, s, cb1, cb2, and others) rather than a universal quick-coupler fit.

Across its four build series the P115 kept the same jaw and crushing mechanism — Cat re-bracketed and re-pinned the same mechanical pulverizer body to keep pace with new carrier generations, from ADM's early B/G/J-linkage 320/325 and CB1/CB2-linkage 324D/325D fitments through AEK's wider C/D/S-linkage coverage, AFP's step up to 330/345B/345C/350-class carriers, and AGX's final expansion to 345/350/365/365BII/375-class machines. Caterpillar's current work-tool catalog no longer lists the P115/P120/P130/P140 line at all; it has been superseded by the hydraulically actuated Secondary and Primary Pulverizer series (the P2xx and P3xx lines), which use cab-controlled jaw cylinders instead of a linkage-driven mechanical jaw. That makes the P115 a discontinued, legacy tool today, but a large population of C- and D-series excavators built for its original linkage classes remains in the field, so demand centers on rebuild wear parts — pins, bushings, jaw teeth, wear plates, and cylinder seal kits — rather than complete new units, with buyers matching serial prefix and linkage code to confirm fitment before ordering.

Caterpillar P115 specifications

Engine

Power sourceNone. The P115 is a passive mechanical pulverizer with no engine, ECM, or onboard hydraulic pump. Jaw closing force is transmitted mechanically from the carrier excavator's boom/stick cylinder linkage.
Emissions tierNot applicable — no engine fitted.

Weights

Operating weightNot published in available Cat work tool catalog literature for this legacy model. Confirm with a dealer for the exact configuration.
Shipping weightNot documented for this model.

Dimensions

Jaw opening800 mm (31.5-32 in) — figure appears as both 32 in and 31.5 in across catalog listings, but the metric value is consistent at 800 mm.
Carrier/mounting compatibilityListed for the Cat 318C excavator in one catalog table and for Cat 320D and 324D excavators in another, spanning the C-series to D-series excavator generation change.

Performance

Force at throat (crushing force)96 short tons (850 kN).
Tool typeMechanical pulverizer for secondary demolition — pulverizes and reduces concrete debris after primary breaking/crushing. Fixed-jaw mechanical design, not a hydraulically actuated jaw.
Product line notePart of Caterpillar's early Mechanical Pulverizer line (P115, P120, P130, P140), sized for 20-30 ton class excavators. This line was later superseded by Cat's hydraulic Primary and Secondary Pulverizer series; the P115 does not appear in more recent work tool catalogs.

Service capacities (summary)

Fuel tankNot applicable — no engine.
Hydraulic systemNot applicable — no independent hydraulic reservoir or pump; operates off the carrier excavator's own hydraulic/mechanical linkage.
Engine oilNot applicable — no engine.
Cooling systemNot applicable — no engine.

Values vary by configuration, region, and serial range — confirm against your machine before planning transport or lifts.

P115 fluids & capacities

SystemCapacityRecommended fluid
Hydraulic power supply (jaw cylinder)Not applicable — no onboard reservoirP115 has no hydraulic tank or pump of its own. The jaw cylinder is plumbed into the host excavator's (Cat 318C/320D/324D-class carrier) auxiliary hydraulic circuit, so fluid type, viscosity grade, and change interval follow the carrier's own OMM hydraulic-oil recommendation, not a P115-specific spec.
Engine, cooling system, fuel tank, transmission/powertrain, final drives, axles/differentialsNot applicableP115 is a passive mechanical pulverizer work tool (part of the P115/P120/P130/P140 family) with no engine, ECM, coolant circuit, fuel tank, transmission, or axle of its own — these systems do not appear in its lubrication chart.
Pivot pins, bushings, and toggle-link jaw mechanism (grease)Not a filled capacity — apply at grease fittings until purge is visible at each pin jointGeneral-purpose Cat multipurpose grease (NLGI 2, EP) at daily/scheduled fittings; for heavier-loaded pin joints on demolition work tools like this, Cat dealers commonly step up to Cat Advanced 3Moly Grease for its higher load-carrying, high-impact rating. Cold-climate service should use a grease rated for the ambient range down to about -20°C (-4°F); exact grade call-out was not confirmed against a located P115-specific OMM page, so verify the fitting-by-fitting grease grade against the OMM/dealer bulletin for the exact serial/AEK prefix before servicing.

Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Caterpillar P115 maintenance schedule

Service intervalTasks
Every 10 h
  • Wipe down the jaw and visually inspect teeth, wear plates, and the throat area for cracks, chips, or mushrooming before the first cycle of the day or week.
  • Grease every pin and bushing point at the jaw hinge and mounting bracket until fresh grease purges the joint.
  • Check the crushing cylinder rod and glands for weeping, scoring, or fresh oil film.
  • Confirm mounting pins and retaining hardware are fully seated with no visible play against the host excavator's stick/linkage.
  • Clear packed concrete dust and debris from the hinge pockets so grease reaches the bushing rather than sealing over it.
  • Cycle the jaw through a full open/close range before starting work and watch for binding or uneven closing.
Every 250 h
  • Measure pin-to-bushing clearance at the jaw hinge and mounting-bracket ears against service limits and log the trend.
  • Inspect jaw teeth and wear plates for material loss; rotate or replace before base metal is exposed.
  • Test crushing-cylinder pressure at the tool to separate a tool-side seal problem from a carrier-side pump or relief-valve issue.
  • Re-torque mounting-bracket and structural fasteners to spec and replace any hardware with damaged threads.
  • Inspect welds and the jaw throat under good light for early fatigue cracking.
Every 500 h
  • Remove and inspect the main pivot pin for scoring, out-of-round wear, or heat discoloration from running dry.
  • Replace bushings that have exceeded the clearance limits flagged at the 250-hour check.
  • Inspect the crushing cylinder rod seal and glands for weeping; rebuild the seal kit if any seepage is found.
  • Confirm the mounting bracket still fits the host carrier's linkage tightly, with no elongation of the pin bores.
  • Check jaw alignment and closing evenness across the full stroke.
Every 1,000 h
  • Disassemble the tool at the jaw hinge and mounting-bracket joints for a full pin-and-bushing wear survey rather than spot checks.
  • Re-bush any joint at or beyond wear limits and replace pins as a matched set to keep clearance even side to side.
  • Inspect the frame and jaw weldments for stress cracking near the throat and mounting-ear radii.
  • Have the host excavator's boom/stick pin bores and weld seams checked as well — pulverizer shock-loading stresses the carrier faster than routine digging.
Every 2,000 h
  • Run a full structural inspection of the frame, jaw, and mounting ears, including a crack check on any prior weld repairs.
  • Rebuild the jaw pivot and mounting joints with new pins and bushings regardless of measured wear if the tool has seen heavy demolition cycling.
  • Evaluate jaw teeth and wear plates for full replacement rather than incremental patching.
  • Rebuild the crushing cylinder with a full seal kit and pressure-test it before returning the tool to service.
Every 4,000 h
  • Send the frame and jaw throat out for dye-penetrant or magnetic-particle crack inspection before further heavy service, especially after multiple prior weld repairs.
  • Replace the complete pin-and-bushing kit at the hinge and mounting bracket rather than spot-replacing individual worn parts.
  • Weigh cumulative wear and rebuild history against the tool's linkage class to decide whether a re-bush and re-pin covers remaining service life or the tool should be retired.
  • Confirm the tool still matches its host carrier's linkage geometry (b, c, g, cb1, cb2, and later codes) after years of pin wear and any earlier weld repair.

Servicing the P115 beyond the schedule

Predictive Maintenance & Fluid Analysis

The P115 carries no engine oil, hydraulic reservoir, or coolant to sample — fluid analysis applies to the host excavator's hydraulic system, not the tool. Predictive care instead means tracking crushing force and cycle speed for gradual drop-off, which flags a bypassing cylinder seal or a carrier-side pump/relief-valve problem before it fails outright. Log pin-and-bushing clearance at the jaw hinge and mounting ears on a fixed schedule, and watch jaw-tooth wear-plate thickness trend against baseline so tooth changes happen before base metal wears through.

Corrective & Common Repairs

Most P115 repairs center on three points: jaw teeth and wear plates chipped or rounded at the throat, a pivot pin and bushing racking sideways once clearance opens up, and the single crushing cylinder weeping at the rod seal until the jaw creeps closed at idle. Because the cylinder draws off the carrier's bucket/aux circuit rather than an onboard pump, test cylinder pressure at the tool before condemning either side — weak crushing force is as often a worn carrier pump or relief valve as a tool-side seal failure.

Overhaul & Rebuild Points

A full P115 overhaul re-bushes every load-bearing joint — jaw pivot and mounting-bracket ears — replacing pins as a matched set rather than one at a time. Crack-check the jaw throat and frame welds first, since fatigue shows there before anywhere else on a heavily cycled unit. Because mounting geometry shifted across the ADM, AEK, AFP, and AGX build series, verify pin-bore spacing and linkage-code fit against the host carrier before returning the rebuilt jaw to service.

Seasonal & Environment Servicing

Grease selection matters more than schedule changes across seasons for the P115's pin joints — step up to a cold-flow-rated EP grease, or Cat's higher-load 3Moly grease for heavy demolition duty, so the jaw hinge and mounting bracket stay lubricated at startup below about -20°C. Rebar-heavy or reinforced concrete work packs grit and debris into the hinge pockets faster than clean demolition, so shorten grease intervals and clear packed debris before it grinds into the bushings. Coat exposed pins and welds with a corrosion inhibitor during wet-season storage.

P115 attachments & work tools

Work-tool identity and size class

P115 is the smallest model in Caterpillar's P115/P120/P130/P140 mechanical pulverizer family, a demolition jaw attachment for hydraulic excavators, not a standalone machine. It is sized for roughly 20-25 metric ton class carriers such as the Cat 320, 324D, 325 and 325D; the P120 steps up to 322-330 class carriers, with P130 and P140 covering 330 through 375 class machines.

Carrier compatibility and mounting

The P115 has no universal quick-coupler. It pin-mounts directly to the excavator's stick and linkage through a dedicated bracket group and link group matched to that carrier's specific linkage code, for example "b", "c" or "g" linkage on the 320/325, "cb1" linkage on the 324D, and "cb2" linkage on the 325D. A different mounting kit is needed for each carrier/linkage combination, even within the same base excavator model, because Cat revised stick-and-linkage geometry across production series.

Jaw actuation and hydraulic arrangement

The tool is cataloged as a mechanical pulverizer arrangement: jaw movement is driven off the excavator's own stick/tool hydraulic circuit rather than a separate high-flow auxiliary kit. On the 324D/325D "cb"-linkage mounting kits the arrangement adds its own supplemental cylinder and bracket set as part of the mount; most other linkage kits (b, c, g, s, etc.) use brackets, pins and links only, with no dedicated pulverizer cylinder.

Guarding and factory labeling

Each P115 unit ships with a plate-and-film group carrying warning decals for flying debris, crush hazard/stay back, general alert, and read-OMM notices, plus a lift-eye location decal and a P115 identification film. The P120/P130/P140 siblings use the same labeling package, differing mainly in the model-identification decal, while frame, jaw and mounting hardware remain size-specific.

Lineup generation and options

P115/P120/P130/P140 are documented together as one mechanical-pulverizer family spanning several serial-prefix production runs. Caterpillar's current pulverizer catalog uses a different naming scheme (secondary and primary pulverizer lines sized to excavator class), so no direct one-for-one successor is confirmed for the P115 specifically - check current cross-reference and any rotation or quick-coupler adapter availability with your dealer before ordering.

P115 serial number reference

The P115 ID plate is riveted to the pulverizer frame near the mounting/boom-bracket end and is visible with the jaw open. Read the first three letters as the build-series prefix and the digits after it as the unit sequence number within that series; parts books express fitment changes as "S/N XXX1-Up", meaning that prefix and every unit built after it.

PrefixIdentifies
ADMEarliest confirmed build series for the mechanical pulverizer arrangement
AEKSecond build series, widens host-machine coverage
AFPThird build series, mid-size excavator coverage
AGXLatest confirmed build series, widest host-machine range

Frequently asked questions

What engine does the Cat P115 have?

None. The P115 is a passive mechanical demolition pulverizer with no engine, ECM, transmission, or hydraulic pump of its own. Its crushing jaw is driven mechanically through the host excavator's boom/stick cylinder linkage, so all power comes from whatever carrier — historically a Cat 318C, 320D, 324D, 325, or 325D-class excavator — it is pin-mounted to.

What is the P115's operating weight?

No factory operating-weight figure has been published in available Cat work-tool catalog literature. Field listings put an unmounted P115 near 850 kg (about 1,870 lb), consistent with its 96-short-ton (850 kN) force-at-throat rating and 800 mm jaw opening, but treat that figure as an estimate and confirm the exact number for your unit's serial prefix (ADM/AEK/AFP/AGX) with a dealer.

What replaced the Cat P115?

No direct one-for-one successor is confirmed. The P115 belonged to Cat's legacy P115/P120/P130/P140 mechanical pulverizer family, sized for roughly 20-30 ton class carriers; Cat's current work-tool catalog no longer lists that line at all, having moved to the hydraulically actuated Secondary (P2xx) and Primary (P3xx) Pulverizer series, which use a cab-controlled cylinder rather than a linkage-driven mechanical jaw.

What P115 owners discuss

What carriers does the P115 fit, and does it need a dedicated hydraulic kit?
The P115 is sized for 320D/324D-class carriers, roughly the 20-24 metric ton excavator range, alongside larger siblings P120/P130/P140 that step up to 325D, 330D, 345C and 365C L class machines. It is cataloged as a mechanical pulverizer work tool: the crushing jaw is driven by a single cylinder mounted at the tool, run off the carrier's standard bucket or auxiliary circuit rather than a dedicated high-flow hammer circuit. There is no engine, ECM, or onboard electronics on the tool itself - any "power" complaint traces back to the host excavator's hydraulic system, not the pulverizer. Mounting on machines of this era is typically pin-on rather than a quick-coupler, so match pin diameter and ear spacing to your stick/link before buying.
Where does the jaw wear first, and how do owners handle tooth replacement?
The rows of teeth on the moving and fixed jaw take the brunt of the work. Operators report the teeth dull and chip first at the crushing throat and along the leading edge, especially when the jaw is worked into rebar-heavy or heavily reinforced sections instead of clean concrete. Older concrete with lighter rebar engineering is noticeably easier on teeth than modern reinforced slabs. Community practice is to rotate or replace teeth before wear reaches into the jaw plate itself - once the base metal starts wearing, repair cost jumps well beyond a simple tooth swap.
What is the most common wear failure on a P115-class pulverizer?
The heavy-duty pivot pin and bushing at the jaw hinge is the wear item owners flag most. On mechanical pulverizers in this size class, users have reported breaking or wearing out multiple pins when the tool is run aggressively on 30-ton class carriers, faster than they typically see on other attachments. Regular greasing at the pivot and periodic measurement of pin and bushing wear against factory tolerance is the standard preventive step. Once the pin develops play, the jaw racks sideways under load and accelerates bushing wear on both sides - don't run it loose. Have your dealer verify pin/bushing tolerances before returning the tool to heavy service.
How does the crushing cylinder typically fail, and how do you tell tool-side from carrier-side hydraulic problems?
The single crushing cylinder is the other main wear point. Reported symptoms are the usual hydraulic cylinder signs: a weeping rod seal that worsens under load, crushing force falling off as the seal bypasses internally, or the jaw creeping closed when the tool sits idle. Because the P115 draws off the carrier's own bucket/aux circuit rather than an onboard pump, weak crushing force is just as often a carrier-side issue - worn main pump, a relief valve creeping out of spec, or contaminated fluid - as it is a tool-side seal failure. Isolate the two by testing cylinder pressure at the tool before condemning either side. Have your dealer verify relief valve settings and cylinder pressure readings before a full rebuild.
Does running a pulverizer put extra stress on the host excavator itself?
Operators in this equipment class consistently describe pulverizer work as harder on the carrier than routine digging. Reported issues include pins wearing or breaking faster than normal use, and in at least one case a boom needing replacement after developing stress cracks from repeated pulverizer loading. The jaw's shock-loading crushing action, especially biting into reinforced concrete, puts cyclic stress into the stick, boom, and pin joints that a bucket rarely sees. Inspect stick/boom pin bores and weld seams more frequently when a machine runs a pulverizer regularly, and have your dealer verify any suspected stress cracking in structural members before continued use.
What should you inspect when buying a used P115?
Start at the jaw throat: look for cracks radiating from the crushing area or around the tooth mounts, not just tooth wear, since that's where fatigue cracking shows up first on a heavily used unit. Check the pivot pin and bushings for play - grab the jaw and rock it; any noticeable slop means the pin/bushing set is due. Inspect the cylinder rod for scoring and the glands for weeping, and cycle the jaw fully to check for binding or uneven closing. Confirm the mounting ears and pin bores on the tool match your carrier's stick/link geometry, since these were commonly pin-on rather than coupler-mounted. Weight for this tool runs in the neighborhood of 850 kg (about 1,870 lb) unmounted - verify that against your carrier's lift chart at full reach before committing. Have your dealer verify structural welds and pin bore wear on any unit with heavy service history before you put it back to work.
