Caterpillar MP40
Maintenance schedule, common problems & OEM parts breakdown
The Cat MP40 is a hydraulic multi-processor, a bolt-on jaw attachment for demolition and scrap processing that mounts on a large excavator carrier rather than working under its own power. It has no engine, fuel system, coolant system, or transmission. A single large cross-mounted cylinder and a 360-degree hydraulic rotator draw all power from the host excavator's hydraulic circuit. It sits at the top of the legacy MP15/MP20/MP30/MP40 housing family and pairs with large carriers, roughly a 45-95 tonne class spanning Cat 345 through 390-series excavators depending on which generation of factory literature is consulted. Housing-and-jaw operating weight runs about 6,370-6,730 kg (14,045-14,835 lb) in current-generation literature, varying with the jaw fitted; earlier-generation documentation shows lighter figures around 5,800-6,000 kg (12,787-13,228 lb) for the same jaw types. The MP40 takes Concrete Cutter, Shear, Crusher, and Secondary Pulverizer jaw sets on one common rotator housing, letting a contractor cover primary breaking, steel cutting, secondary crushing, and rebar-from-concrete separation by swapping jaws rather than tools.
Spec figures for the MP40 shifted across factory-sheet generations, with current-generation weight and force ratings running meaningfully higher than earlier documentation for the same jaw types. That reads as a genuine design update to the tool, not a mix-up with a different model. Separately, Cat has since introduced a newer multi-processor line built around a faster jaw-locking system and fewer grease points, expanding over time to cover a wider range of carrier sizes; the MP40 itself is now listed as non-current in Cat's own product catalog. That shift makes the MP40 mainly a used-equipment and parts-support tool today. Demolition and scrap contractors running older 370-390-class carriers keep MP40 housings working by rotating between jaw sets and sourcing wear items, teeth, cutting knives, pivot pins, bushings, and cylinder seals, rather than replacing the whole attachment, since the rotator housing and cylinder typically outlast several jaw-wear cycles.

| Cutter/knife length | 250-760 mm (9.8-29.9 in) depending on jaw type. Shear jaw carries the longest cutting edge at 760 mm (29.9 in); Secondary Pulverizer and Crusher jaws use a shorter 250 mm (9.8 in) cutter. |
Performance
| Carrier excavator weight class | Matched to Cat 345, 349, 365, 374, 385 and 390 hydraulic excavators in current factory literature, roughly a 45-95 tonne carrier class. Earlier factory documentation matched this tool to Cat 365B L and 375 L excavators, a similarly sized but earlier-generation carrier lineup. |
| Maximum crushing/shearing/cutting force | Varies by jaw type and jaw location. At the tooth/jaw tip: 1,450-1,890 kN. At the primary blade center: 3,060-5,040 kN. At the throat (Shear jaw only): up to 8,840-8,950 kN, the highest force point on any MP40 jaw. Concrete Cutter and Crusher jaws peak near 4,330-4,650 kN at the primary blade. |
| Cycle time | 7.5 seconds for a full open-close-open cycle, consistent across all MP40 jaw sets and factory-literature generations. |
| Arm/cylinder torque | Cross-mounted cylinder produces 1,855-2,000 kN-m fully open and 1,081-1,358 kN-m fully closed, per current factory data for Concrete Cutter and Shear jaws. |
| Required carrier hydraulic flow | About 400 L/min (105.7 US gal/min) to the jaw open/close circuit and about 80 L/min (21.1 US gal/min) to the rotation circuit, per the Cat factory spec sheet for this tool size. |
| Maximum working pressure | 350 bar (35,000 kPa / 5,076 psi) on the jaw cylinder circuit and 140 bar (14,000 kPa / 2,031 psi) on the rotation circuit, per the Cat factory spec sheet. One earlier document lists a higher 550 bar cylinder rating specifically for the Crusher-jaw configuration; treat that figure as unconfirmed and verify current circuit rating with your dealer. |
| Rotation | Continuous 360-degree hydraulic rotation, controlled by joystick or pedal in the cab, positions the jaw against material without repositioning the carrier. |
Service capacities (summary)
| Fuel, coolant, engine oil | None. This attachment has no engine; it draws all power from the carrier excavator's hydraulic system. |
| Hydraulic reservoir | No separate reservoir on the tool. It shares the carrier excavator's hydraulic tank, pump and filtration. |
| Grease points | Rotator bearing (360-degree hydraulic rotation drive) and jaw pivot pins are grease-lubricated per the factory lubrication schedule. Jaw teeth and knives are wear items, not lubrication points. |
| Hydraulic line configuration | Two-way high-pressure lines feed jaw open/close; two-way medium-pressure lines feed rotation, selectable by joystick or pedal control per customer preference. |
Values vary by configuration, region, and serial range — confirm against your machine before planning transport or lifts.

Servicing the MP40 beyond the schedule
Predictive Maintenance & Fluid Analysis
The MP40 has no engine, transmission, or reservoir of its own. It runs off the carrier excavator's hydraulic system, sharing its tank, pump, and filtration. Predictive care on this tool means monitoring the CARRIER's hydraulic oil condition, since demolition duty cycles heavy jaw loads and abrasive particulate from crushed concrete and rebar back through the shared circuit. Sample the carrier's hydraulic oil on schedule, watch for contamination trends after heavy MP40 use, and track rotator drift and cylinder cycle time as early wear indicators specific to this tool.
Corrective & Common Repairs
Most MP40 repairs trace to a handful of recurring wear points: cylinder rod seals weeping oil after heavy cycling, pivot pin and bushing wear at the jaw and rotator joints that shows up as play grease can't take up, and worn jaw teeth or cutting knives that lose bite on rebar and steel plate. Reversible cutting edges buy extra service life before replacement is needed. Catch seal weep and pin play early. Both worsen quickly under demolition's high-shock loading and can damage the housing pin bores if left unchecked.
Overhaul & Rebuild Points
Planned overhauls on the MP40 center on the rotator bearing and drive gear, the housing wear plates, and the pin bores at the jaw and cylinder mounts. Backlash in the rotator signals bearing or gear wear that a rebuild can correct before the housing itself takes damage. Elongated pin bores from years of high-impact jaw cycling need bushing or bore repair to restore proper pivot alignment. Budget a rebuild around major jaw-set changeovers, since the housing is already open for inspection at that point anyway.
Seasonal & Environment Servicing
Demolition sites load the MP40 with concrete dust, rebar fragments, and abrasive debris that packs into pivot joints and grease fittings. Clear this buildup before greasing so grease reaches the bushing surface instead of sitting on top of packed grit. Switch to a heavier, tackier grease grade in hot climates where standard grease can run out of the joint, and confirm cold-weather grease still pumps freely through fittings in winter. Rinse debris from the rotator seal area regularly on demolition and recycling jobs to keep abrasive grit away from seals.
MP40 attachments & work tools
Interchangeable Jaw Sets Overview
The MP40 uses one common rotator housing that accepts bolt-on interchangeable jaw sets rather than accepting separate attachments. Per Caterpillar's own matching guide the MP40 is offered with four jaw types: Concrete Cutter, Shear, Crusher, and Secondary Pulverizer. The Tank Shear and Primary Pulverizer jaws offered on the smaller MP15-MP30 housings are not listed for the MP40.
Concrete Cutter Jaw
Used for primary demolition of reinforced concrete, combining a crushing jaw with an integrated cutter blade to shear rebar as the concrete is broken. On the MP40 this jaw opens to about 1280 mm (50.4 in), has a jaw depth of about 1100 mm (43.3 in), and delivers up to roughly 4400 kN crushing force at the blade center.
Shear Jaw
Used to cut structural steel, angle and channel iron, beams, plate, pipe, rebar, and cable during steel demolition and scrap processing. The MP40 shear jaw is rated to cut narrow I-beams up to about 600 mm (23.6 in) high with roughly 19 mm (0.75 in) flange thickness, and produces up to roughly 8950 kN shear force at the throat.
Crusher Jaw
Fits the same MP40 housing with toothed crushing jaws for secondary demolition and downsizing of concrete, masonry, and reinforced material after primary breaking. Jaw opening is about 1320 mm (52.0 in) with up to roughly 4650 kN crushing force at the primary blade center.
Secondary Pulverizer Jaw
Used for secondary-stage processing: separating rebar from already-crushed concrete and further reducing debris to manageable size for sorting or removal. On the MP40 this jaw opens to about 1400 mm (55.1 in) and delivers up to roughly 5500 kN crushing force at the primary blade center; it is the pulverizer variant offered for this size, not the primary/first-pass pulverizer jaw used on smaller MP models.
Coupler and Mounting System
The MP40 mounts to the carrier excavator stick through a mounting bracket, allowing the same tool to be moved between compatible carriers, and can be fitted with Caterpillar's dedicated pin-grabber quick coupler system so it can be swapped for other Cat work tools in seconds rather than requiring a pin-and-bushing changeover. The housing itself provides continuous 360-degree hydraulic rotation so the jaw can attack material from any angle without repositioning the carrier.
Hydraulic Circuit Requirements
The carrier must supply two-way high-pressure hydraulic lines for jaw open/close plus a separate two-way medium-pressure circuit for rotation, selectable from an in-cab joystick or foot pedal. The MP40 jaw cylinder circuit demands up to about 400 l/min (106 US gpm) at up to 350 bar (5075 psi) working pressure, giving a full open-close-open cycle of about 7.5 seconds; the rotation circuit runs up to about 80 l/min (21 US gpm) at up to 140 bar (2030 psi).
Carrier Excavator Weight Class
Caterpillar's matching guide pairs the MP40 with large excavators in the 345C, 365C, and 385C class, roughly a 45 to 90 tonne (50-100 ton) operating-weight range depending on carrier model and configuration. Total MP40 tool weight (housing, jaw, and bracket) runs about 5800-6000 kg (12,800-13,200 lb) depending on which jaw is fitted.

MP40 serial number reference
The PIN plate sits on the multi-processor's own housing (the tool body carrying the hydraulic rotator and cylinder), not on the carrier excavator, since the tool is sold and tracked as its own serialized product. Read the first three characters as the serial prefix identifying the specific tool/jaw family and production run, then the digits after it as the sequential unit number within that run. Jaw sets carry a separate plate and prefix from the tool body they mount to, so check both plates if you are matching a jaw set to a housing.
| Prefix | Identifies | Notes |
|---|---|---|
| JMZ | Jaw group serial prefix (combination, crusher, pulverizer and shear jaw sets) | Covers the interchangeable jaw sets fitted to the MP40, starting at JMZ00001-UP with no documented end serial. This range sits in the same parts book as the sibling multi-processor sizes, which use their own letter: MP15 jaws use JMW, MP20 use JMX, MP30 use JMY. Treat JMZ as the jaw serial family, separate from the tool body serial. |

Does the MP40 have its own engine?
No. The MP40 is a hydraulically powered attachment with no engine, fuel system, coolant system, or transmission of its own. It runs entirely on hydraulic power supplied by the host excavator's auxiliary circuit, sharing the carrier's hydraulic tank and pump.
What is the MP40's operating weight?
Housing-and-jaw operating weight runs about 6,370-6,730 kg (14,045-14,835 lb) in current factory literature, depending on the jaw set fitted: Concrete Cutter and Crusher jaws are lightest at roughly 6,370 kg (14,045 lb), Shear about 6,430 kg (14,175 lb), and Secondary Pulverizer heaviest at 6,730 kg (14,835 lb). Earlier-generation documentation lists lower figures, around 5,800-6,000 kg (12,787-13,228 lb), for the same jaw types, reflecting a design revision over time.
What jaw sets does the MP40 support, and what carrier excavator size does it pair with?
The MP40 supports Concrete Cutter, Shear, Crusher, and Secondary Pulverizer jaw sets on one common housing. The Tank Shear and Primary Pulverizer jaws offered on the smaller MP15-MP30 housings are not offered for the MP40. It pairs with large carriers, roughly a 45-95 tonne class spanning Cat 345 through 390-series excavators, with the exact match depending on factory-literature generation and required hydraulic flow (about 400 L/min to the jaw circuit and 80 L/min to rotation). Confirm the specific pairing with your dealer.
What MP40 owners discuss
How much wear should I expect on the MP40's jaw tips and cutting edges before they need replacing?
The jaw halves use bolt-on and pin-on wear segments instead of welded overlay, so worn material gets swapped out on site instead of sending the whole jaw out for a rebuild. Wear shows up first on the tip segments and the crossing edges, since that's where the actual shearing or crushing bite happens. On a machine chewing through rebar-heavy concrete or mixed demolition debris daily, check tip condition every couple hundred hours and change segments once the wear flats start changing the bite geometry. Running tips past that point makes the jaw work harder to close and speeds up wear everywhere behind them, including the pivot area. Keep a spare set of wear segments on hand if the tool sees daily use — running it worn is the biggest driver of secondary wear on the rest of the jaw.
The pivot pins on my MP40 jaw have some play in them. Is that normal?
Some play develops over time on any pin-and-bushing jaw joint — that's the wear part of the design working as intended, not a fault. What's not normal is play you can feel by hand-rocking the jaw halves with the machine shut down. Left alone, a sloppy pivot loads the jaw unevenly, which accelerates bushing bore wear and can eventually elongate the pin holes in the housing casting itself. At that point you're not swapping a bushing anymore, you're welding up and re-boring. Grease the pivot points on schedule, more often in wet or abrasive dust, and pull the pins for a look as soon as the jaw feels loose or the bite stops closing evenly on both sides. Catching it at the bushing stage is a same-day fix. Have your dealer verify pin and bore tolerances if you're not sure whether wear is within limits.
I've got a slow hydraulic leak around the MP40's cylinder. Is that just normal wear?
Weeping at the rod seal after years of cycling is common on any high-cycle demolition cylinder. The seal sees constant heat, job-site dust contamination, and side-load from crushing and shearing forces that a straight-line cylinder wasn't originally built around. A light oil film on the rod isn't an emergency, but a running drip means the seal is done, and it needs changing before grit starts riding the rod past a failing seal and scores the barrel. Watch for a drop in clamp or cutting force too — that's often the first sign of internal bypass before oil ever shows up on the outside. A scored rod turns a seal job into a rod replacement, so don't let a known leak run for months. Have your dealer verify cylinder and rod condition if clamp force feels weak.
My MP40's rotator seems to slowly turn on its own when I let go of the control. Is that a problem?
A hydraulic rotator that holds a dead-still position is the ideal, but a little creep over time isn't unusual as the internal seals age — it's the same internal-bypass story as any hydraulic actuator under load. What matters is the rate: slow, steady drift over a period of minutes is ordinary wear you can keep an eye on. A rotator that spins freely on its own or won't hold at all under load is a seal or valve failure, and that's a different situation entirely once you're swinging a loaded jaw near a structure or a crew. If the creep is getting worse week to week rather than staying steady, pull it in for seal service rather than working around it. Have your dealer verify rotator seal condition before running it near personnel or overhead work.
Can I run an MP40 on a smaller excavator than it's normally paired with?
You can bolt it on if the boom and stick can physically lift and position it, but the MP40 is sized for large excavators in roughly the 60-80 tonne class for a reason — the auxiliary hydraulic circuit needs to deliver flow and pressure in the range the tool was designed around. Undersize the carrier and you're starving the tool: weak crushing and cutting force, sluggish rotation, and jaws that labor through material they should chew through easily. Go the other way and put it on a carrier that pushes more flow than the tool is rated for, and you risk the opposite problem — extra pressure works the cylinder and rotator seals harder and shortens their life, and it runs the oil hotter than the tool's cooling was sized to handle. Match the carrier's auxiliary circuit to the tool's rated flow and pressure window, not just its lift capacity.
How long does it take to swap jaw sets on the MP40, and what should I check afterward?
Cat's jaw-locking design lets one operator change jaw sets in around 15 minutes without special tools, which is the whole point of the multi-processor concept: one housing, several jaw sets for cutting, crushing, shearing, or pulverizing. After a swap, don't load it straight into work — cycle the jaw open and closed a few times empty and watch that the pins seat fully and both jaw halves close evenly. Confirm the locking mechanism is actually engaged, not just resting in place, and regrease the new pivot points before putting the tool to work. A jaw set that's been sitting in storage often needs fresh grease at the pin joints even if it looks clean on the outside.
What should I check before buying a used MP40?
Start with the jaws: look at wear-segment condition and whether the bite closes evenly on both sides. Uneven wear usually points to a pivot problem, not just jaw hours. Shut the machine down and hand-rock the jaw halves to feel for play at the pivot pins — noticeable slop means the bushings, or worse the pin bores, are on their way out. Cycle the rotator through a full 360 degrees and watch for hesitation, uneven speed, or drift when you stop it mid-turn, all signs of internal seal wear. Check the main cylinder for weeping at the rod seal and look for scoring on the rod itself, since a scored rod means the seal will keep failing no matter how many times it's replaced. Ask which jaw sets come with the housing and confirm they're the matching size and generation, since jaw sets aren't interchangeable across different Multi-Processor sizes. None of this replaces a hands-on inspection — have your dealer verify pin and bushing tolerances, rotator seal condition, and cylinder integrity before you commit to buying.
