MST M542 2008 Parts Catalog – Factory Spare Parts Documentation

If you are rebuilding a water pump on an MST M542 backhoe loader and you reach for an aftermarket parts book, you are asking for trouble. I have seen too many jobs go sideways because someone ordered a generic bearing or a wrong gasket set. The only way to get the correct Parts Catalog information – the exact OEM part codes, quantities, and exploded views – is to use the factory document. This 2008 edition, part number M542-08-K01, spans 32 pages and covers every major assembly from the water pump to the hydraulic plumbing. No third-party reprints, no scanned junk.

Every page in this catalog comes from the original MST print run. Page 1/065 shows the water pump assembly with part codes like U5MW0194 for the complete pump kit and 24880232 for the gear. Over on page 1/068 you get the water pump repair kit breakdown – U7LW0172 – including the impeller, roller bearing, oil seals, and circlips. That level of detail saves you a trip back to the parts counter. You order what is actually on the machine, not what a data entry guy thought was close enough.

Water Pump Assembly: OEM Part Codes and Quantities

Look at the water pump section starting at page 1/065. The table lists every piece: the pump kit (Qty 1), gear, gasket, and screws with their thread sizes. Screws are coded 2314K164, 2314H005, 2314H012 – each with a specific head and length. Aftermarket catalogs often combine those into a generic bolt pack that fails the first time you torque it. This catalog gives you the exact reference code so you can cross-check against MST stock.

Water Pump Repair Kit: Exploded View on Page 1/068

Page 1/068 decomposes the repair kit. You get the impeller, roller bearing (separate from the plain bearing), two different seals, two circlips, the drive shaft, and the cover gasket. Each component has a note column that tells you which kit it belongs to. That matters because mixing seal types can cause leaks at the shaft. I have had to pull a pump twice because the seal height was off by 2 mm. The part code 3682A011 for the water pump gasket is identical to the one listed on the pump page – that is consistency aftermarket publishers never bother with.

Why OEM Parts Catalog Over Aftermarket Books?

Aftermarket parts lists cut corners. They reuse drawings from older models, swap part numbers, or omit revision updates. This catalog was published in 2008 with the latest revisions from MST. The note on each page reads “LAST UPDATED : 16.12.2008” and the issue number M542-08-K01. That date tells you the document was current when the machine was built. If you are working on a 2008 machine, this is the only source that matches exactly. For a broader context of why OEM documentation matters, see Automotive Industry Overview.

Using the Catalog Before Disassembly – Workshop Tip

Before you pull the water pump, lay the catalog open to the relevant page. Write down the part codes you will need – the pump kit, gaskets, seals. Order them while the machine is still running. That way you are not waiting three days for a $2 circlip. And if you need to understand the engine systems beyond the parts list, Internal Combustion Engine gives you the theory. But the parts numbers here are the ones that fit.

The 32-Page Structure – What You Get

This catalog is not a thick binder. It is 32 pages focused on the spare parts that wear out: water pump, hoses, pipes, and the associated hardware. Each section starts with a title page (e.g., “SU POMPASI / WATER PUMP”) and then an exploded table with pos numbers, codes, descriptions, and quantities. No fluff, no theory, no torque specs – because this is a parts catalog, not a service manual. If you need repair procedures, you need the MST M542 service manual. But if you need to order parts, this is the book.

FAQ

Does this catalog include torque specs?

No. This is a parts catalog, not a repair manual.

How do I use the part numbers from the catalog to order replacement parts?

Each page has a table with columns: POS (position on diagram), YEDEK PARÇA KODU (spare part code), REFERANS KODU (reference code if the part belongs to an assembly), PARÇA TANIMI (description), MİKTAR (quantity), and NOT (note). Locate the assembly you need, find the part by position, write down the YEDEK PARÇA KODU, and give that code to your MST dealer. The reference code tells you which assembly the part belongs to – if you need the whole pump, order the kit code like U5MW0194. If you only need the gear, order 24880232. Do not trust aftermarket cross-references; stick with the factory code printed here.
