Takeuchi TW50 Parts Catalog – Factory Parts Breakdown for Your Wheel Loader

Ordering the wrong part for a wheel loader costs you time and money. I’ve seen guys spend a whole afternoon chasing a hydraulic fitting that doesn’t match the old one because they used a generic parts list. This Takeuchi TW50 Parts Catalog fixes that. It’s the same 115-page book the dealer pulls up when you call. No aftermarket re-drawings, no translations that swap bolt grades. Factory part numbers, factory quantities, and factory serial number breaks. If your TW50 starts at serial E105833, this is the book you need.

Lifting Unit Parts – Page 5 of the Catalog

The lifting ram, working ram, shims, and grease fittings are all laid out with individual part numbers and quantities. Page 5 shows the complete Lifting Unit (item 8017301) with every bolt, shim, and split bush. Need the 1.0 mm shim? Part number 4674104. Want to know how many grease nipples go on the boom? Five, and the catalog calls out 0324590. You don’t guess. You order once.

Hydraulic System Components – What the Manual Covers

Steering hydraulics (5820072), working hydraulics (5820069), return hydraulics (8016949), driving hydraulics (5820070) – all listed with their main assemblies. The catalog breaks the hydraulic quick release coupling (8010455) and the oil pressure pump (8019516) into sub-groups. If you’re rebuilding the system, you can trace every hose and coupling without pulling the machine apart twice. The Takeuchi TW50 Parts Catalog gives you the exact part numbers for the return filter and tank assembly too.

Engine and Drive Set – 7 Systems Broken Down

Diesel engine (8016801) with exhaust system (8016950), front axle (5820057) with pipe (8014145), rear axle (5820058) with multiple pipe (8009421), and the drive set (5820056). Seven major assemblies are each given their own sub-section with part numbers, quantities, and serial number applicability. You get the same data the factory uses to build the machine. No interpretation, no “compatible with” guesses.

Does This Parts Catalog Include Torque Specs?

No. This is a parts catalog, not a service manual. Torque values, fluid capacities, and repair procedures are in the Takeuchi TW50 Service Manual. If you need to install a new lifting ram or rebuild the steering cylinder, get both manuals. The parts catalog tells you what to order; the service manual tells you how to put it together. They work as a pair. For the smaller TL26 loader, the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual covers that machine with the same factory-level detail.

Why OEM Documentation Beats Aftermarket

Aftermarket parts catalogs often combine serial number ranges or omit “obsolete” parts. This one tracks the serial number break at E105833. If your machine is above that, every part number is valid. The cover page clearly states “Book No. 8017699 01.10 S/N E105833.” Takeuchi printed this, not a third-party re-seller. The document includes the full main parts list (page 0-1) and the lifting unit breakdown (page 2). You can cross-reference part numbers against what you pull off the machine. According to the Automotive Industry Overview, consistent part numbering is a hallmark of proper traceability in equipment maintenance.

Wild guesswork stops here. Every time I see a guy order a part based on a part number from a forum, I tell him to buy the factory catalog. One wrong digit and you wait two weeks for the wrong part. This catalog gives you the exact Takeuchi part number, the quantity needed (Q’ty column), and any service notes (Serv. Remarks column). The hydraulic lifting unit (8016631) is listed with a quantity of 1. You can’t get that from a screenshot.

Does this catalog include exploded-view diagrams?

Yes. The lifting unit on page 2 shows a numbered diagram with corresponding part numbers on page 3. Each main assembly (steering hydraulics, drive set, etc.) has its own figure reference.

What serial numbers does this cover?

It covers serial number E105833 and up. The front cover clearly marks “S/N E105833~”. If your machine is older, you need a different edition. Check the book number on the cover against your serial number.

The cost of ordering one wrong part for a Takeuchi wheel loader often exceeds the price of this catalog. Factory part numbers, factory quantities, factory serial number breaks. Stop relying on memory or forum posts. Access the Factory Manual and keep it on your shop tablet or printed out. You’ll use it every time you rebuild an axle or replace a ram.
