Caterpillar MP15

Maintenance schedule, common problems & OEM parts breakdown

The Caterpillar MP15 is a hydraulically powered multi-processor, a demolition work tool that mounts on a hydraulic excavator's stick, boom, or reach boom rather than running under its own power. It carries no engine, no transmission, no fuel tank, and no onboard cooling system; every function, jaw open/close and continuous 360-degree rotation, draws directly off the host excavator's hydraulic circuit. Operating weight (housing, jaw, and mounting bracket) runs about 1800 to 1900 kg (roughly 3970 to 4190 lb) depending on which jaw set is fitted, since Concrete Cutter, Shear, Crusher, Primary Pulverizer, and Secondary Pulverizer jaws each carry a different weight on the same common housing. Caterpillar sized the MP15 as the entry point of its multi-processor line, matching it to excavators in roughly the 15 to 33-plus tonne class spanning the 315 through 336 model range (including M-series and D-series carriers), and also to Ultra High Demolition (UHD) high-reach carriers up through the 385 class for reach-and-reduce demolition work. The tool line dates to around 2000 and remained in the Cat catalog through the following decade, spanning B-series carrier linkages through later C-series and D-series carrier generations.

Inside the family, the MP15 sits below the larger MP20, MP30, and MP40, which step up in weight, jaw opening, and crushing/shear force for bigger carriers and heavier structures. One notable exclusion carries through every generation of documentation: Tank Shear jaws, used for cutting steel plate on tanks, barges, rail cars, and similar vessels, were built only for the MP20 and MP30 housings and were never offered for the MP15. Caterpillar has since moved its current multi-processor lineup to a different model naming structure, which pushes MP15 units into the used equipment and parts market rather than new-unit sales. Demolition and concrete recycling contractors keep these tools running because the common housing accepts field-swappable jaw sets for cutting, crushing, and pulverizing on one base unit, and the wear items, jaw tips, reversible cutting knives, and crusher teeth, see steady turnover as they wear down against reinforced concrete and structural steel. That turnover keeps parts demand active for the MP15 well after the tool left Cat's current-production lineup.

MP15 fluids & capacities

System	Capacity	Recommended fluid
Pin and bushing lubrication (jaw pivot pins, cylinder mounting pins, rotator bearing)	Grease-to-purge at each fitting per the work tool's service interval, not a fill-and-check capacity	NLGI 2 extreme-pressure grease; Cat's own moly-fortified grease (Cat Advanced 3Moly Grease) is the factory-recommended type for work tool pin and bushing joints

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

Caterpillar MP15 maintenance schedule

Service interval	Tasks
Every 10 h	Grease every jaw pivot pin and bushing point on the housing and both jaw halves before the start of each shift. Grease the 360-degree rotator bearing fittings. Visually inspect jaw tips, cutting knives, and crusher teeth for cracks, chipping, or rounded edges. Check hydraulic hoses and fittings running to the tool for leaks, chafing, or loose clamps. Confirm the mounting bracket and quick-coupler pins are fully engaged and locked before demolition work begins.
Every 50 h	Re-torque jaw pivot pin retainer bolts and housing-to-bracket mounting bolts to specification. Inspect the main cylinder rod for scoring, pitting, or oil weeping past the rod seal. Cycle the jaw open-close-open sequence and confirm smooth, even travel on both jaw halves. Check the rotator drive area for oil seepage at the seal. Clear packed dust, concrete fines, or debris from pivot points before greasing.
Every 250 h	Check pin-to-bushing clearance at all jaw pivots against wear limits. Inspect housing wear plates and side plates for gouging, thinning, or cracking. Flip or rotate reversible cutting knives once one edge shows wear, and check jaw tips for remaining service life. Inspect hydraulic hoses and fittings for abrasion damage and replace any weeping seals. Check the rotator bearing for play or roughness through a full rotation cycle.
Every 500 h	Inspect the main cylinder clevis and cross-head pin bores for elongation or wear steps. Check the rotator seal for leakage into the gear case and replace if hardened or seeping. Torque-check all structural fasteners joining the housing, bracket, and jaw pivots. Inspect wear plates and lifting eyes for fatigue cracking from repeated impact loading. Replace jaw pivot pins or bushings that exceed the measured wear limit.
Every 1,000 h	Remove and inspect jaw pivot pins and bushings; replace any pair rather than mixing new and worn parts. Inspect the main cylinder internally for seal wear and reseal if the jaws lose closing force under load. Inspect the rotator bearing race and seal assembly and replace worn components. Inspect the housing structure, pivot bosses, and lifting eyes for cracks. Verify hydraulic relief and flow settings on the host excavator circuit match the tool's rated pressure and flow before returning it to service.
Every 2,000 h	Perform a full teardown inspection of the jaw housing, pivot bores, and pin bosses for wear beyond factory tolerance. Rebuild or replace the rotator bearing and seal assembly. Reseal or overhaul the main hydraulic cylinder as wear and leakage warrant. Replace wear plates and worn jaw sets to restore factory jaw geometry and clamping alignment. Re-torque all structural fasteners to specification and inspect welds for fatigue cracking.

Servicing the MP15 beyond the schedule

Predictive Maintenance and Fluid Analysis

The MP15 has no hydraulic reservoir of its own; it draws off the host excavator's shared circuit, so route oil sampling through the carrier's hydraulic tank whenever the tool sees heavy service, watching for elevated water content or wear metal that could originate from the tool's own cylinder or rotator seals rather than the carrier. Pull periodic grease samples from the jaw pivot and rotator lube points and check for metallic content, which flags advancing pin, bushing, or bearing wear before it shows up as visible play in the jaws.

Corrective and Common Repairs

Reseal the single large cross-mounted cylinder when the rod shows oil weeping past the gland or the jaws lose closing force under load. Rotator seal leakage lets moisture and grit into the bearing race, so replace the seal at the first sign of weeping and check the bearing for play before it scores the rotation housing bore. Jaw pivot pins and bushings absorb the brunt of cutting, crushing, and shearing loads; measure clearance regularly and replace worn pins and bushings in matched sets, not mixed new and used.

Overhaul and Rebuild Points

Jaw tips, crusher teeth, and cutting knives are the MP15's highest-wear parts across all five jaw types; most knives are reversible or individually replaceable, so flip or swap them before the base jaw metal underneath starts eroding. Rebuild the jaw housing's wear plates once gouging or thinning shows through the surface hardening, since a worn housing lets pivot pins walk and accelerates bushing wear. On a full rebuild, check the pivot bosses and lifting eyes for cracking from repeated impact loading, and verify jaw alignment and stop-bolt settings after reassembly.

Seasonal and Environment Servicing

Switch to a lower-temperature-rated moly EP grease before cold-weather demolition work so the jaw pivots and rotator bearing keep accepting grease at start-up instead of channeling. On wet or dusty sites, grease pivot points more often than the base interval calls for, since concrete dust and standing water both accelerate seal wear at the rotator and jaw pins. Wipe down and inspect the rotator seal and pivot boots after wash-down or heavy rain, and re-grease immediately to purge any moisture that worked past the seal lips.

MP15 attachments & work tools

Excavator Carrier Class

Cat's own multi-processor matching guide pairs the MP15 with the 315-336 class of hydraulic excavators (roughly 13 to 36 tonne / 14 to 40 ton operating weight), including M-series (M313, M315, M316, M322) and D-series (319D, 320D) carriers. The same jaw/housing combination is also matched to Ultra High Demolition (UHD) high-reach carriers up to the 385C class (roughly 85 tonne / 94 ton) for the largest reach-and-reduce jobs; exact pairing varies by series and dealer recommendation.

Mounting / Coupler Interface

The MP15 attaches to the host stick/arm through a dedicated linkage mounting bracket rather than a bucket-style pin-on fitting, and the bracket lets the same tool body be exchanged among several compatible carrier models. When the carrier is fitted with Cat's CW quick-coupler system, the MP15 can be swapped for other Cat work tools in seconds without a separate bracket change.

Jaw / Tip Tooling Options

The MP15 housing accepts five interchangeable jaw sets: Concrete Cutter, Shear, Crusher, Primary Pulverizer, and Secondary Pulverizer, letting one base unit demolish reinforced concrete, cut structural steel and rebar, or process debris for recycling. Unlike the larger MP20/MP30/MP40 in the same family, the MP15 is not offered with the Tank Shear jaw.

Hydraulic Rotator & Auxiliary Circuit

Continuous 360-degree hydraulic rotation is built into the MP15 housing and runs on a dedicated medium-pressure rotation circuit (up to roughly 40 l/min / 10.6 gpm at 140 bar / 2,031 psi), separate from the high-pressure jaw-cylinder circuit (up to roughly 150 l/min / 40 gpm at 350 bar / 5,076 psi) that opens and closes the jaws. Both circuits are run from the host excavator and controlled by an in-cab joystick or pedal, so the carrier must supply two-way high-pressure lines for the cylinder plus two-way medium-pressure lines for rotation.

MP15 serial number reference

The MP15 carries its own PIN/serial plate mounted on the tool's own housing (the rotator and hydraulic body between the excavator mounting bracket and the jaw set) - it is not the excavator's PIN, so always read the tag on the tool itself when ordering jaw or hydraulic parts. The plate shows a 3-letter prefix followed by a sequential unit number; parts documentation expresses this as "prefix + 1-Up," meaning every unit built from that block forward, and the prefix alone tells you which production/parts-book block (and which compatible jaw and bracket parts range) a given unit falls into.

Prefix	Identifies	Notes
ABR	MP15 base multi-processor unit (all jaw types)	Caterpillar's shared multi-processor parts documentation lists ABR as the MP15 unit's own machine-serial block. The same document family lists the MP20, MP30 and MP40 siblings under their own separate, distinct ranges, not under ABR. Traced to secondary parts-catalog listings rather than a directly-read OEM bulletin - confirm exact block cutoff with a dealer.
JMW	MP15 base multi-processor unit, current Multi-Processor Jaws parts manual (all jaw types)	The current Multi-Processor Jaws parts manual lists JMW as the machine-serial range for the MP15, while the same manual separately lists the MP20, MP30 and MP40 siblings under their own distinct ranges. Covers compatibility for combination, crusher, pulverizer and shear jaw groups on the MP15 housing. Appears to be a later production block than ABR; exact date break not documented - confirm with a dealer.

Frequently asked questions

What excavator size does the Caterpillar MP15 fit?

The MP15 is matched to hydraulic excavators in roughly the 15 to 33-plus tonne class, covering the Cat 315 through 336 model range, including compact M-series and D-series carriers. It is also matched to Ultra High Demolition (UHD) high-reach carriers up through the 385 class for reach-and-reduce demolition work. Exact fit depends on stick or boom configuration and hydraulic plumbing, so confirm compatibility with your dealer before mounting.

What is the operating weight of the Caterpillar MP15?

Operating weight (housing, jaw, and mounting bracket) runs about 1800 to 1900 kg (roughly 3970 to 4190 lb), varying by which jaw set is installed. Concrete Cutter, Shear, and Crusher jaws sit near the lighter end around 1800 kg, while Primary and Secondary Pulverizer jaws push closer to 1850 to 1900 kg.

What jaw and tip options does the Caterpillar MP15 offer?

The MP15 accepts five interchangeable jaw sets on its common housing: Concrete Cutter, Shear, Crusher, Primary Pulverizer, and Secondary Pulverizer. Tank Shear jaws, used for cutting tank and barge plate, are not offered for the MP15; that jaw type is reserved for the larger MP20 and MP30 housings. Jaw tips, crusher teeth, and cutting knives are replaceable or reversible wear parts across all five jaw types.

What MP15 owners discuss

What do owners and mechanics report about cylinder and rod-seal life under demolition shock loads?

The MP15 runs a single large-diameter, cross-mounted cylinder with an armored rod and the cylinder body shrouded inside the housing, a design response to the shock loading demolition work produces. Field experience with Cat multi-processors and demolition shears as a class points to sudden pressure-release events as the main driver of rod-seal failure rather than gradual wear: the instant a beam, pipe, or reinforced section gives way, the resisting load disappears and a pressure spike runs back through the circuit. Seals tend to hold up fine for long stretches, then let go abruptly once the seal lip has been repeatedly extruded into the rod-to-gland clearance under those spikes. A rod showing scoring, or weep starting at the gland after hard use, is the early warning sign, not a slow steady drip. Have your dealer verify seal and gland condition, and confirm the excavator's relief settings, before returning a rebuilt unit to full production.

How does jaw-tip and blade wear actually play out, and how practical is the jaw changeover in the field?

Caterpillar rates the changeover at about 15 minutes using standard hand tools, working off the lifting eyes and adjustable stop bolts built into the jaws and housing, and operators running the tool day to day generally confirm one person can do it in that range once they know the sequence. Cutting knives are reversible, so flipping a dull edge doubles usable life before a knife needs outright replacement, and crusher teeth are replaceable separately from the jaw casting itself. Wear rate is dictated far more by material than by the tool: clean structural steel and pipe are comparatively easy on the edges, while reinforced concrete loaded with grit and rebar rounds edges faster and pushes up how often knives get flipped or teeth get swapped.

What causes rotator bearing and seal wear, and how do operators avoid it?

Across multi-processor and demolition-shear attachments generally, premature rotator wear traces back to using the 360-degree rotation to twist, pry, or drag a clamped structure while the rotator is engaged, instead of using it only to position the jaw before biting. The bearing is not built to take that kind of side load, and repeated abuse shows up as play or a rough, notchy feel through the rotation rather than smooth travel. Demolition sites also load the rotator's seals hard with concrete dust, grit, and water, so once a seal starts to weep, contamination reaches the bearing races quickly afterward. Sticking to a regular grease schedule and treating the rotator strictly as a positioning aid rather than a demolition force is the standard advice given for this class of tool.

How does the MP15's hydraulic flow and pressure need to match against different excavator carriers?

The MP15 is rated for roughly 150 l/min (about 40 US gpm) to the opening/closing cylinder at up to 350 bar (about 5075 psi), and roughly 40 l/min (about 10.5 US gpm) to the rotation circuit at up to 140 bar (about 2030 psi). Caterpillar's own matching guide ties the MP15 to hydraulic excavators in roughly the 13 to 36 tonne class for direct stick mounting, extending to Ultra High Demolition carriers in the 80-plus tonne class when the tool rides on a reach boom instead. Running the tool on a carrier with less auxiliary flow than that starves the cylinder and visibly slows both the cutting cycle and rotation speed. Pairing it with a carrier well above its rated flow, without the excavator's relief and flow-control valves properly set for the tool, is what the wider demolition-attachment trade flags as a path to overheated oil and premature seal wear in both the main cylinder and the rotation motor. Match the tool to a carrier at or near its rated flow window rather than assuming a bigger excavator is automatically the safer choice.

What should a buyer check when looking at a used MP15?

Start with the main cylinder: the rod should be free of scoring, pitting, or chrome damage, and travel should be smooth with no weeping at the gland. Check the housing itself for cracks or repair welds, particularly around the cylinder trunnion and the jaw pivot bosses, since those areas take the brunt of demolition shock loads over time. Work the jaw pivots by hand for pin and bushing play, and cycle the rotator through a full 360 degrees checking for smooth travel with no backlash or rough spots. Inspect hose routing for chafing, pinching, or old leak staining, and confirm how much life is left on the reversible knives or crusher teeth before they need attention. Finally, confirm the jaw actually matches the housing as an original pairing for that size class rather than a substituted set, and that the hydraulic ports and coupler suit the flow and pressure the intended carrier can deliver. Have your dealer verify cylinder and rotator condition with a full function and pressure test before putting a used unit back into service.

Are jaws interchangeable across the whole MP-series, or only within one size?

Jaws are sized to their own housing, not universal across the MP-series lineup. An MP15 housing only accepts MP15-sized jaws, covering Concrete Cutter, Shear, Crusher, Primary Pulverizer, and Secondary Pulverizer duty, and the Tank Shear jaw was never offered in the MP15 size at all, only in the MP20 and MP30 sizing. Within that one size, jaws are meant to be quick-change, using common lifting-eye and stop-bolt locations on the housing. When buying secondhand, confirm the jaw and housing were sold as a matched pair for that size class rather than assembled from mismatched stock.

Is a multi-processor easier on the carrier than a hydraulic hammer, and does that change how it should be operated?

Multi-processors are non-impact tools: they cut, crush, or pulverize with steady hydraulic force rather than repeated percussive blows, so they run at a comparatively low noise level and do not hammer shock into the stick and boom pins the way a breaker does. That advantage disappears the moment an operator uses the excavator's own tractive force against a clamped structure. Backing the machine up or swinging against material the jaws are still gripping reintroduces the same kind of shock loading the tool's design is otherwise meant to avoid, and it is the habit most often blamed for cracked jaws, stressed pins, and shortened cylinder-seal life on these tools.
