Caterpillar MP20
Maintenance schedule, common problems & OEM parts breakdown
The Cat MP20 is a hydraulic multi-processor, a jaw-type demolition and scrap-processing work tool that mounts on an excavator's stick through a hydraulic 360-degree rotator rather than a machine in its own right. One common housing built around a single cross-mounted cylinder and rotator accepts six interchangeable jaw sets: Concrete Cutter, Shear, Tank Shear, Crusher, Primary Pulverizer, and Secondary Pulverizer, so one tool covers everything from structural steel demolition to concrete recycling depending on which jaw is pinned on. Complete operating weight runs roughly 2,550-2,750 kg (5,620-6,060 lb) depending on the jaw fitted, sized for host excavators in the 20-35 tonne class. The MP20 sits in the middle of Caterpillar's MP15/MP20/MP30/MP40 multi-processor lineup, a step up from the smaller MP15 and below the heavier MP30 and MP40, and has been factory-cataloged across at least two generations of Cat excavators.
Cat's factory compatibility charts shifted along with the excavator lineup itself. An early brochure ties the MP20 to B-series carriers, stick-mounted on the 322B L, 325B L, and 330B L (boom-mounted on the 320B L), while a later brochure extends the fit to the C/D-series 318C through 336D range plus larger UHD long-reach demolition carriers. Serial-prefix ranges moved in step: an older production block tied to the 320B-era linkage, mounting-bracket ranges built for the 330C, and a current parts-manual generation carried under its own prefix alongside the MP15 and MP30 siblings. Because the tool has no engine or fuel system to wear out, its value on the used market comes down almost entirely to pin, bushing, cylinder, and rotator condition rather than hours on a powerplant, and buyers need to confirm which jaw sets and which carrier class a given unit was actually built and used for before pricing it.

Service capacities (summary)
| Fuel tank | Not applicable. No engine on the tool. |
| Hydraulic system | No onboard reservoir. The tool draws flow and pressure from the host excavator's auxiliary circuit through two-way high-pressure lines for jaw open/close and two-way medium-pressure lines for rotation. |
| Engine oil | Not applicable. |
| Cooling system | Not applicable. Cooling is handled by the host excavator's hydraulic oil cooler. |
| Lubrication | Grease-lubricated pivot pins and rotation bearing. No oil-fill service points on the tool itself. |
Values vary by configuration, region, and serial range — confirm against your machine before planning transport or lifts.
MP20 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Grease points - jaw pivot pins, cylinder pins, rotator bearing/drive | No fill volume; apply grease at each point until purged (visible at the joint), per the tool's grease decal/interval schedule | Extreme-pressure, moly-fortified multipurpose grease (Cat multipurpose/EP-moly grease line); no separate oil system on the tool itself |
| Hydraulic power supply (compatibility note only, not a tool capacity) | N/A - the tool has no onboard hydraulic tank; it runs off the host excavator's own hydraulic circuit and reservoir | Use whatever hydraulic fluid the host excavator's own OMM specifies (e.g., Cat HYDO or an equivalent AW-type hydraulic oil); this is a host-machine fluid requirement, not a fluid carried by the multi-processor |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the MP20 beyond the schedule
Predictive Maintenance & Hydraulic Condition Monitoring
The MP20 has no engine oil to sample, so predictive care centers on the host excavator's hydraulic oil and the tool's own grease. Have the carrier's hydraulic fluid sampled on its normal interval; the MP20 draws directly off that same circuit, so contamination or degraded oil there shows up first as sluggish jaw speed or weak rotation. On the tool side, watch grease color and consistency purged at each pivot for early signs of water intrusion or metal fines before they turn into bushing wear.
Corrective & Common Repairs
Most MP20 repairs trace to three spots: pivot pin and bushing play from skipped grease intervals, a rotator swivel seal weeping oil after heavy hours, and a main cylinder rod seal that lets the jaw creep open under load. A quick-coupler or pin-grabber that has gone oval will make the whole tool rock even when the jaws themselves are tight. Sluggish jaw or rotation speed with no visible leak usually points back to the host excavator's circuit flow or pressure setting rather than the tool.
Overhaul & Rebuild Points
A full MP20 rebuild replaces the pivot pin-and-bushing set together rather than one at a time, since mixing new and worn parts leaves the jaw misaligned. Cylinder overhaul means checking the rod and bore for scoring once internal bypass shows up as jaw creep, then honing or sleeving before reseal. Rebuild the rotator seal package and check bearing play under load at the same visit, since a leaking seal and a worn bearing present the same symptom. Inspect castings near pin bosses for fatigue cracking before returning the tool to service.
Seasonal & Environment Servicing
Cold weather calls for a lower-temperature grease at the pivots and rotator so it still pumps to the joint instead of channeling; a joint that runs dry in freezing conditions wears fast. Demolition dust and concrete fines pack into exposed pin joints faster than clean scrap work, so shorten the grease interval in abrasive material rather than holding a fixed hour figure. On a tool parked outdoors between jobs, cycle the jaws and rotator through full travel before use and check exposed rod and pin surfaces for surface rust.
MP20 attachments & work tools
Concrete Cutter Jaws (CC)
For precise cutting and demolition of heavily reinforced concrete. Cuts structural steel and pipe in the same pass. Fitted with replaceable concrete crusher teeth and reversible steel-cutting knives.
Shear Jaws (S)
For demolition of steel structures. Cuts angle iron, channel, beams, pipe, rebar, cable and tires. Cutting knives are reversible for extended service life.
Tank Shear Jaws (TS)
Cuts steel plate on tanks, barges and railway cars. Dual reversible knives on both the moving and static jaw leave a smooth, straight edge. Offered only for the MP20 and MP30 in this family, not the MP15 or MP40.
Crusher Jaws (CR)
For demolition of moderately reinforced concrete. Crushes the concrete and cuts exposed rebar in one motion. Fitted with replaceable crusher teeth and reversible knives.
Primary Pulverizer Jaws (PP)
Combination jaw for first-pass demolition and recycling of moderately reinforced concrete. Pulverizes the concrete, cuts rebar and begins separating rebar from concrete. Replaceable crusher teeth and reversible knives; this jaw is not offered on the largest unit in the lineup (MP40).
Secondary Pulverizer Jaws (PS)
Finishing/recycling jaw run after primary crushing or pulverizing. Pulverizes remaining concrete, fully separates rebar from concrete and trims rebar as needed to prep material for recycling.
Mounting, rotator and coupler system
All jaw sets bolt to one common housing built around a single large cross-mounted cylinder with a hydraulic 360-degree rotation drive, letting the tool attack material from any angle without repositioning the carrier. Jaws are swapped in the field using lifting eyes and adjustable stop bolts on the jaw and housing, after initial calibration. The housing mounts to the host excavator stick with a dedicated bolt-on bracket sized to that carrier's linkage, and pairs with a Cat pin-grabber-style quick coupler so the tool can be exchanged for other Cat work tools in minutes.
Hydraulic-kit / auxiliary line requirements
Needs two-way high-pressure hydraulic lines for jaw open/close plus a separate two-way medium-pressure circuit for rotation, switched from an in-cab joystick or foot pedal per customer preference. This tool-control kit can be installed at the factory or added in the field on the host excavator. Required working pressure and oil flow scale with the jaw set fitted; heavier jaws such as tank shear or crusher call for more flow than the lighter cutter jaws.
Host excavator size class and models
Sized for roughly 20 to 33 tonne (22 to 36 ton) class excavators. On the older B-series lineup it is a stick-mounted tool for the 322B, 325B and 330B, and a boom/reach-boom-mounted tool for the 320B. On the C/D-series lineup it carries the 318C, 320C/320D, 322C, 323D, 324D, 325C/325D, 329D, 330C/330D and 336D. Factory documentation also lists it for larger Ultra High Demolition (UHD) long/high-reach carriers in the 325-385 class plus a dedicated demolition carrier, since the lighter MP20 suits extended-reach work better than the larger MP30/MP40 at height. Exact host fit varies by series and boom/stick configuration; confirm against a specific serial with your dealer.

MP20 serial number reference
The MP20 has no engine, so its serial plate sits on the attachment itself - look on the main housing or cylinder guard near the pin-on mounting ears where the tool attaches to the excavator stick, and read the 3-letter prefix followed by the sequence number.
| Prefix | Identifies | Notes |
|---|---|---|
| ABS | MP20 base/main production block, all jaw and housing configurations | Covers shear, crusher, pulverizer and combination jaw-group listings for the MP20 housing across the shared MP15/MP20/MP30/MP40 multi-processor parts manual. Mounting references for this era tie to a Cat 320 "B"-family excavator linkage. |
| ACF | Early MP20 production range, paired with ABS | Appears alongside ABS across the same shear, crusher, pulverizer and combination jaw-group listings for the MP20. Treat as an earlier or parallel MP20-specific range rather than a shared/ambiguous one; exact cutoff between ACF and ABS production is not documented, so confirm the split with your dealer if it matters for a specific unit. |
| MPF | MP20 mounting-bracket serial range (330C carrier, universal UHD linkage) | Tied to the MP20 mounting bracket used on a 330C-class carrier with universal UHD linkage. Only one document family ties this to the MP20 specifically rather than a sibling model - confirm with your dealer before ordering against this prefix alone. |
| M2X | MP20 mounting-bracket serial range (330C carrier, universal UHD linkage), paired with MPF | Listed together with MPF for the same 330C universal-UHD-linkage mounting bracket. Single document family ties it to the MP20 - confirm with your dealer before ordering against this prefix alone. |
| JMX | Current parts-manual generation MP20 prefix | Used across shear, pulverizer, crusher and combination jaw-group listings in the newer shared MP15/MP20/MP30/MP40 multi-processor manual; OEM parts-manual listings name this range specifically under the MP20 machine designation, distinct from JMW (MP15), JMY (MP30) and JMZ (MP40) in the same generation. |
Frequently asked questions
Does the Cat MP20 have an engine, or what powers it?
No. The MP20 has no engine, fuel tank, or onboard electronics of its own. All hydraulic flow and pressure for jaw open/close and for the 360-degree rotator come from the host excavator's own auxiliary hydraulic circuit, up to about 200 L/min (52.8 US gpm) at 350 bar (5,076 psi) for the jaw cylinder and 40 L/min (10.6 US gpm) at 140 bar (2,031 psi) for rotation.
What does the MP20 weigh?
Complete operating weight (housing, jaw, and mounting bracket) runs about 2,550-2,750 kg (5,620-6,060 lb) depending on which jaw set is fitted; the jaw itself accounts for roughly 1,000-1,150 kg (2,205-2,535 lb) of that total. Shear and crusher-family jaws sit at the lighter end, Primary and Secondary Pulverizer jaws at the heavier end.
What excavators does the MP20 fit, and what replaced it?
Factory charts size the MP20 for roughly 20-35 tonne excavators. Older documentation lists it stick-mounted on the 322B L, 325B L, and 330B L (boom-mounted on the 320B L); later charts extend the fit to the 318C through 336D range and to larger UHD long-reach carriers. Rather than being replaced outright, the MP20 remains part of the same MP15/MP20/MP30/MP40 family, with MP30 and MP40 covering larger carriers and MP15 the smaller end; confirm exact fit for a specific serial with your dealer.
What MP20 owners discuss
How does the MP20's rotator behave day to day, and what should you watch for on rotator seals and bearing life?
The jaw head sits on a continuous 360 degree hydraulic rotator built into the tool housing, driven off the excavator's rotate circuit rather than the jaw-close circuit. A small amount of drift or creep in rotation when the boom is parked at an angle for a while is normal on any hydraulic rotator once the seals and valving have hours on them; it is not by itself a fault. Rotation that will not hold position under load, or that drifts noticeably within a few minutes, points to worn rotator seals or a tired check/counterbalance valve rather than the bearing. The rotator bearing is the long-life item and takes both the jaw's weight and the torque from cutting or crushing at the same time, so it is greased on its own shorter interval separate from the rest of the tool. Skipping that grease point is the fastest way to shorten bearing life. If drift gets worse right after a seal kit goes in, suspect the bearing letting the housing rock rather than another seal leak. Have your dealer verify rotator bearing play before assuming it is a seal-only fix.
How much play is normal in the jaw pins and bushings, and how often do they need attention?
Like any pin-jointed demolition jaw, the pivot pins and the cylinder rod-eye pin ride in replaceable bushings, and those bushings are the first thing to develop play under heavy cycling. A slight side to side movement felt by hand at the jaw tip is expected once the tool has real hours on it. Visible misalignment when the jaws close fully, or an audible knock on every cycle, means the bushings, and sometimes the pin itself, are due for replacement. Grease frequency matters more at these pivots than almost anywhere else on the tool, since they take full crushing or shearing load every single cycle. A missed grease interval shows up as accelerated bushing wear within weeks rather than months. Exact wear limits vary by jaw size and by what the tool has been processing, since rebar-heavy demolition wears pins faster than clean concrete or steel, so judge by feel and visible galling rather than a fixed clearance number.
Where do hydraulic leaks usually turn up, and what does a leak at the main jaw cylinder mean?
The two spots that come up most are the rotator's swivel seal package and the main jaw open and close cylinder's rod seal. A rotator leaving a light oil film after turning is a common sign of aging swivel seals and is normally a straightforward seal kit job. A leak at the main cylinder rod is more serious, especially if it worsens under load or if the jaw slowly creeps open on its own while parked closed. That behavior means the piston or rod seal has failed enough for oil to bypass internally, and left unaddressed it accelerates wear on the rod and cylinder bore until the fix becomes honing or sleeving instead of a simple reseal. A cylinder that will not hold the jaws closed under load is a dropped-load risk on anything suspended in the jaws. Have your dealer verify the cylinder before the tool goes back into service.
How long do cutting edges, blades, and teeth last, and does wear life differ by jaw type?
Wear life differs a lot depending on which jaw is mounted. Shear jaws use bolt-on cutting blades that get indexed to a fresh edge and can be resharpened more than once before they are scrapped; how many cuts you get per edge depends heavily on whether you are cutting clean structural steel or rebar-loaded demolition debris. Pulverizer jaws use replaceable teeth or tips on the jaw face that round off and lose their bite well before the jaw casting itself wears out, and these are treated as a routine field-swappable wear item rather than a failure. Crusher and concrete-cutter jaws wear mainly on the crushing teeth and the heel or anvil area, and heavy rebar work chews through the anvil faster than clean unreinforced concrete. Across all jaw types, mixed material, buried steel, or rock shortens wear life significantly compared to clean debris, so treat any quoted interval as a starting point rather than a guarantee, and expect it to vary by configuration.
What wears on the quick-coupler and pin-grabber end, and are there quirks to watch for when swapping jaws?
The pin-grabber or quick-coupler link between the excavator stick and the tool housing sees the same wear pattern as any excavator quick coupler: the coupler jaws and the mounting pins wear oval over time, and once that play develops the whole tool will rock or clunk under load even if the tool itself is tight. Because the MP20 is built around one common housing that accepts different jaw sets, both that coupler and the housing-to-jaw pinning need to stay free of slop or the jaw will sit slightly off position after every swap, which shows up as jaws no longer closing flush. When changing jaw sets, a common mistake is reusing a worn pin or skipping the grease point at the jaw pivot during reassembly since it is briefly exposed and easy to forget. Both are frequent reasons a freshly swapped jaw set feels loose within the first shift.
What's the most common complaint about running an MP20 on the wrong carrier, and what electrical issues show up on the host machine's side?
The recurring complaint is a carrier whose auxiliary hydraulic circuit is undersized or set to the wrong pressure for the tool. It shows up as slow jaw open and close speed, sluggish or weak rotation, and the tool never quite reaching full crushing or shearing force even though it technically runs. The tool has no pump, motor, or reservoir of its own and depends entirely on the host excavator's hydraulics, so matching the carrier's flow and pressure setting, and confirming the correct rotate circuit type, matters as much as the tool's own condition. On the electrical side the tool itself carries no ECM or sensors. Reported control problems trace back to the excavator's own rotate or auxiliary valve solenoid, or to the in-cab joystick switch and wiring feeding it, and show up as a rotator that will not respond, jerks, or only turns one direction. A miswired or failed solenoid can make the tool move unexpectedly when the operator is not commanding it, so have your dealer verify any aux valve or joystick wiring repair before the carrier goes back to work.
What should you check before buying a used MP20?
Start at every pivot pin and the cylinder rod-eye pin and feel for play; excessive movement here is the clearest sign of hard hours. Cycle the jaws fully open and closed and watch for even closure, since a jaw that closes out of alignment points to a bent jaw, worn pins, or a tweaked housing. Rotate the tool through its full range in both directions checking for binding, and look for a fresh oil film that could mean a recent, undisclosed reseal. Inspect the cutting edges, teeth, or crusher tips for remaining life and confirm they actually match the jaw type being sold, since replacement wear parts add up fast. Look over the housing and jaw castings for weld repairs or cracking, especially around the pin bosses, and ask what material the tool actually processed, since clean concrete and steel wear it far more gently than mixed rebar and demolition debris. Confirm which carrier weight class and which jaw sets came with the tool, since jaws sized for a different housing will not pin up correctly. Given how much of this tool's condition hides in pin, bushing, and cylinder wear, have your dealer verify pin and bushing clearances and cylinder condition before closing the deal.
