Morooka MST-2500 Parts Catalog

If you’ve ever ordered a part for a Morooka MST-2500 and got the wrong one because some aftermarket catalog listed a generic number, you know the headache. That’s why this 79-page OEM parts catalog exists. It comes straight from Morooka, serial number 25134 and up. No guessing. No cross-referencing with a chinese translation. You get the exact exploded diagrams, part numbers, and quantities the factory uses. I’ve been wrenching for 28 years, and I’ve seen a shop lose a whole afternoon because someone ordered a steering valve based on a third-party list. This catalog fixes that.

Engine Related Parts – What’s in the Diagrams

Turn to page 5 of the PDF, and you’ll see FIG. 101 ENGINE RELATED PARTS. That single page has 52 callouts for engine components: everything from the block to the fan. Each callout ties to a part number, description, and quantity. The catalog groups engine parts upfront, so you don’t have to flip through the whole thing to find a water pump gasket. This is not some aftermarket scan – it’s the actual factory illustration with OEM numbers. If you’re rebuilding a Morooka MST-2500, you start here.

Steering Control System – Diagrams 1/2 and 2/2

The steering systems on these carriers are nothing like a pickup truck. They use hydrostatic controls, and when a valve fails, you better have the right replacement. The catalog splits the steering content into two sections: STEERING CONTROL SYSTEM (1/2) and (2/2). The first covers the control valve stack, the second the linkage and cylinders. Each page shows the exact routing of hoses and the part numbers for seals and spools. I’ve had to rebuild one of these; the diagrams save you from ordering a whole assembly when you only need a $6 O-ring.

Electrical System Breakdown (A-110 /3)

Electrical troubleshooting on a rubber crawler carrier can be a nightmare because the wiring looms are buried under the cab. This catalog includes the ELECTRICAL SYSTEM A-110 /3 section, plus a dedicated Battery page (A-15131-252671). The diagrams show the alternator, starter, and fuse box with factory part numbers. If you need the dash panel, the INSTRUMENT PANEL A-10252.2 252471 page gives you the gauge cluster breakdown. Automotive Industry Overview. Understanding the electrical system matters because a short in the wrong place can burn a harness. This catalog helps you order the correct wire harness section instead of splicing in generic wire.

79 Pages of OEM Data – No Aftermarket Guessing

Why does page count matter? Because every page in this catalog comes from the same source that built the machine. The 79 pages cover: Engine Related Parts, Steering Control System (two sections), Hydraulic Piping P/O, Instrument Panel, Electrical System, Battery, and a Numerical Index. That index lets you look up a part number you found on an old tag and cross it to the diagram. You won’t find that in a generic parts listing. I’ve had guys bring me parts that were “supposed to fit” from an aftermarket catalog, and they were off by a bolt hole. This catalog eliminates that waste.

Who Needs This Parts Catalog?

If you own a Morooka MST-2500, you need this. DIYers who do their own maintenance, farm crews who keep these carriers running, and even shops that don’t have a Morooka dealer nearby. When a hydraulic fitting leaks, you look up the O-ring part number on page 4 (the contents list) and find it in the Hydraulic Piping section. The catalog uses Imperial measurements, so you won’t be converting metric to standard. That’s a big deal when you’re ordering from a US supplier. MOROOKA MST-1500 Parts List covers a smaller model; for the MST-2500, this is the one you want. Also check out Morooka MST 500, MST 600, MST 700, MST 800, MST 1100 Service Manual if you need repair procedures instead of just parts. And if you work on old ag equipment, Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide is a different beast but built the same way.

Bottom line: Access the Factory Manual. That call-to-action is straightforward because you don’t need fluff. You need a PDF that shows you the exact part number for the steering control valve, the battery terminals, and the hydraulic pump. This catalog does that. Stop wasting money on wrong parts. Get the factory-sourced breakdown.

FAQ – Morooka MST-2500 Parts Catalog

Does this catalog include repair procedures?

No. This is a parts catalog only – exploded diagrams and part numbers. For repair steps, you need the service manual.

What serial numbers are covered?

Serial No. 25134 and up. Check the first page of the PDF; it says that clearly. If your machine is older, the diagrams may still match, but you should verify by comparing the component visually.

How do I order parts using this catalog?

Find the figure number (e.g., FIG. 101 for engine), locate the callout number, then read across to the part number and description. Take that number to a Morooka dealer or parts supplier. The numerical index at the end helps if you have an old part number and want to see where it belongs on the machine. That index saves hours of flipping pages. I use it myself when a customer comes in with a torn-off tag. You cross-check, find the diagram, and confirm the part is correct before ordering. Saves returns and downtime.

Is the hydraulic piping section detailed enough for a full hose replacement?

Yes. The HYDRAULIC PIPING P/O section shows every hose and fitting with lengths and end fittings. That’s OEM data, so you’ll know if it’s a JIC or ORFS fitting. Get the right hoses on the first try.
