Morooka MST-1500 Parts Catalog – Factory OEM Parts Breakdown

If you are ordering parts for an MST-1500 rubber track carrier and the parts guy asks for a serial number range, you better have this book open. I have seen too many guys order the wrong fuel tank because they guessed at the serial number cut-off. This catalog is 68 pages of factory part numbers, exploded diagrams, and application notes from Morooka itself. It covers machines from serial number 15009 onward. Let me tell you what is inside and why the aftermarket parts catalogs are not worth the paper they are printed on.

Engine Related Parts: More Than Just a Block Diagram

The first section is labeled “エンジン 関連部品” – Engine Related Parts. Figure 101 breaks down every gasket, bolt, hose, and bracket tied to the engine block and exhaust. It includes both the Japanese and English item names so you can cross-reference with local suppliers. The exploded view shows the exact order of assembly – if a bolt goes through a washer then a bracket, the diagram shows it. You will find the air intake and exhaust parts sorted by serial number cut (SERIAL NO.15009-15491). That means if your machine falls outside that range, you need to jump to the later figures. Ignoring that gets you a part that does not fit, and you will pay return shipping.

What the Fuel Tank and Piping Section Actually Shows You

Under “フエル タンク および パイピンク” (Fuel Tank and Piping) the Parts Catalog gives you the tank assembly, the pickup tube, sending unit, and every clamp from the tank to the injection pump. Each component carries a Morooka part number – none of that “equivalent to” garbage. The diagram also marks which parts are semi-finished (triangle symbol) that need drilling or tapping before installation. If you order a triangle part and install it as-is, you will have a fuel leak. I have seen it. This catalog saves you that headache.

68 Pages of Authentic Japanese Factory Data

Morooka printed this catalog for their dealers in Japan. The translation is there but the real value is the figures. Every figure has a “FIG. NO.” and a page number. The steering control system is split across two sub-sections (1/2 and 2/2), and the hydraulic piping spans three serial number ranges. You get separate diagrams for machines built before and after serial 15102. There is even a battery relay section for machines from serial 15942 up. That level of detail is lost when you grab a third-party PDF that merges everything into one blurry scan. This is the real deal.

Understand the Steering and Hydraulic Systems Before You Order a Fitting

Hydraulic hoses and fittings have to be right the first time. The manual divides hydraulic piping into three figures based on serial number breaks: 15009-15102, 15103-15792, and 15793 onward. Each figure lists the length of the hose assembly and the thread type. If you are replacing a steer cylinder line, you can look up the exact part number and confirm it matches your machine’s serial range. The hydraulic oil tank and filter sections also show the filter element part number and the O-ring sizes. Do not mix them up – the return filter is a different micron rating than the pressure filter, and the catalog notes that in the item list.

Serial Number Ranges: Why They Matter

Every section in this Morooka MST-1500 Parts Catalog starts with a “適用号機” line – applicable serial numbers. For example, the instrument panel has three separate figures: one for 15009-15792, one for 15793-15941, and one for 15942 up. The electrical system and battery sections follow the same pattern. If you ignore the serial number, you might order a cluster that does not have the correct connector, and then you are back to ground zero. Write your serial number on the cover of this catalog.

For service procedures covering multiple Morooka models, the Morooka MST 500, MST 600, MST 700, MST 800, MST 1100 Service Manual gives you torque specs and repair sequences. Working on something older? The Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide uses the same approach to OEM documentation. If you want to understand why factory catalogs are superior, the Automotive Industry Overview describes how OEMs control their supply chain. The Automotive Industry Overview also covers the importance of original specifications.

FAQ

Can I use this catalog to rebuild the engine on my MST-1500?

No. This is a parts list, not a service manual. It gives you part numbers and exploded views. You need the service manual for removal and installation procedures. The engine section shows gaskets, seals, and bolts but no torque specs. The Morooka MST 500, MST 600, MST 700, MST 800, MST 1100 Service Manual covers the full service procedures for the engine.

What serial numbers does this cover?

Machines from serial number 15009 onward. Each section sometimes has a narrowed range. Check the “適用号機” (applicable serial numbers) in the diagram.

If you own an MST-1500 and do not have the original Morooka parts catalog, you are flying blind. Every part you order from a dealer is listed here by number, and every diagram is keyed to your machine’s serial range. Stop guessing and get the exact part the first time.
