Yanmar TB150C 2006 Parts Catalog

Yanmar TB150C 2006 Parts Catalog – 37 pages of OEM factory data. No aftermarket guesswork. This is the exact document you need when you’re tearing into a compact excavator and you hit a freeze plug or a seal you can’t cross-reference. I’ve seen too many guys order a part from a third-party list, get the wrong size, and waste a half-day chasing the right one. This catalog kills that.

How to Read This Parts Catalog

Page 1 spells it out: Ref. No., Part No., Name, Description, Quantity columns labeled (A) through (F). The illustration number and list head number might not always align—they warn you right there. Level dots show parent-child relationships for assemblies. Pay attention to the Change Mark ‘I’ and the Interchangeability Marks (N, Q, R, S, W, Z, F, K). If you see an ‘R’, old and new parts swap both ways. If you see ‘N’, only new replaces old. That saves you ordering a part that won’t bolt up.

Fuel Injection Pump Components – Fig. 29

Fig. 29 covers the FUEL INJECTION PUMP (W/BOOST). Ref. No. 1 is the pump assembly – part number 129470-51300, VOGF161. Ref. No. 1-1 is a SCREW M 16 (799500-0602), qty 9 per pump. Ref. No. 1-2: SCREW M 10×65 (799500-0604), qty 4. The gasket (129470-51540) and roller bearing (122210-51910) are listed with exact quantities. If you’re rebuilding a 4JH-DT or 4JH-DTZ engine, note the boost compensator type – marked with an asterisk and special notes for engine serial numbers up to E/#00155. That kind of detail keeps you from ordering a wrong compensator.

Level and Interchangeability Marks Explained

The catalog uses a dot-level system: one dot for parent parts, two for child, three for grandchild, four for great-grandchild, and a star for the last child. Non-sale parts are not listed. The interchangeability table – N, Q, R, S, W, Z, F, K – tells you exactly how a changed part behaves. For example, ‘Q’ means the old part retrofits into the new assembly but the new part won’t go backward. That’s the kind of spec you need when you’re sourcing a used part. Relying on a generic parts list will bite you.

37 Pages of Factory Specs – No Fluff

Yanmar compiled this catalog for dealers and builders. 37 pages. Each page is a dense grid of part numbers, descriptions, and quantities. There’s no filler, no marketing. Just the data. The Effective Machine No. column tells you exactly which serial number range each part applies to. If you own a TB150C with a serial number above 14510004, this catalog matches your machine.

Why OEM Documentation Matters

Aftermarket part catalogs often merge multiple model years or skip interchange notes. This one came from Yanmar in 2006. Every part number is factory-verified. The Automotive Industry Overview has plenty of examples of counterfeit or mismatched parts causing downtime. I’ve seen it firsthand. When you’re ordering the fuel injector pump gasket or a screw M10x65, you want the exact part that Yanmar stamped. This catalog gives you that.

FAQ

Does this catalog include part numbers for the fuel injection pump?

Yes. Fig. 29 lists the pump, screws, gasket, bearing, and retainer with full part numbers and quantities.

How do I use the interchangeability marks when ordering replacement parts?

Check the Interchangeability Mark column in any parts list. Each mark (N, Q, R, S, W, Z, F, K) tells you whether the old and new parts swap. For example, ‘R’ means completely interchangeable both ways. ‘N’ means new replaces old but not vice versa. If you see ‘Z’, that part is abolished and no longer available. Always verify the Effective Machine No. column to match your serial number. If you skip this step, you risk ordering a part that won’t fit, which wastes time and money—especially on older equipment like the TB150C where manufacturers may have updated components across production runs.
