Yanmar 4TNE92-HRJ Parts Catalog – 16-Page OEM Factory Spec Document

You’ve got a **Yanmar 4TNE92-HRJ** on the bench and need to order replacement parts. Without the factory parts catalog, you’re gambling on aftermarket cross‑references that might get you a gasket that doesn’t seal or a bearing that’s 0.25 mm off. That costs you time, money, and a second teardown. This 16‑page OEM Parts Catalog gives you the exact part numbers, lever codes, and quantities that Yanmar stamped into the original build. No guesswork – just the factory spec.

Most guys skip the catalog and grab a generic parts list from the internet. Then they wonder why the oil pump won’t line up or the cylinder head gasket has the wrong number of holes. I’ve seen it a hundred times. This document is the same one the dealer uses. It’s split into clear figures – Fig.1 CYLINDER BLOCK and Fig.2 GEAR HOUSING – with a full table of parts, lever codes (A through F), and OEM numbers like 729904-01560 for the block assembly. If you need the exact bolt for the gear case cover, it’s right there: 26106-080162 for M8×16 plated bolt. No need to measure threads with a ruler.

One key thing about this catalog: it includes oversized and undersized part numbers. The cylinder block assembly shows main bearing sets with US=0.25 and OS=0.25 options. If your crank has been ground, you order those specific bearings – not the standard ones. That’s the kind of detail that keeps an engine together at full load. The gear housing section lists the lubricating oil pump assembly (129900-32001) and every seal, O‑ring, and bolt that goes with it. Each part has a reference number and quantity. You can rebuild the entire front of the engine from this single page.

Cylinder Block – Fig.1 Part Breakdown

Fig.1 covers the core of the Yanmar 4TNE92-HRJ. It lists the cylinder block assembly, head gasket, main bearing sets, thrust bearings, camshaft bush, plugs, and all 18 head bolts. The lever column (A–F) tells you which variant of the engine uses that part. For example, level (A)=4TNE92-HRJ; other levels may apply to different models. If you’re rebuilding, pay attention to the “Remarks” – under‑sized and over‑sized parts are clearly marked. The 16‑page catalog gives you every part number for a full short‑block overhaul. Need the thrust bearing for a 0.25 OS crank? It’s there: 129900-02941, quantity 2.

Gear Housing Assembly – Fig.2 Details

Fig.2 is the front gear case and housing. It includes the gear case cover assembly, oil pump, oil seals, O‑rings, the filler cover, and every bolt – from M8×12 to M8×70. The oil pump assembly (129900-32001) is called out with its own ball bearing (129900-26250). If you’re replacing the front crankshaft seal, you need the oil seal part number (129900-01780) from this figure. I’ve seen guys reuse the old seal because they couldn’t find the number – then the engine leaks at the next startup. This catalog stops that. Also note the “OPTIONAL PART” remark for certain components – those aren’t always on every build, so check your engine’s serial number range.

Parts Catalog vs Service Manual: Know the Difference

This is a parts catalog – not a service manual. It tells you what parts go where and their correct part numbers, but it doesn’t give torque specs, clearance values, or overhaul procedures. For that you’d need the factory service manual. But if you’re ordering parts, this is the only source you should trust. Aftermarket parts books often combine multiple engine families and miss the lever‑code variations. The Yanmar 4TNE92-HRJ catalog is model‑specific. If you see a part number like 729904-01560, that’s the genuine Yanmar block assembly for your engine – no generic substitute.

Automotive Industry Overview highlights why factory documentation matters for reliability and safety. The same principle applies here: using OEM parts avoids catastrophic failures. The Automotive Industry Overview also notes that proper documentation reduces maintenance errors.

How to Read the Lever Codes (A–E)

Every table in this catalog has a lever column. Each lever corresponds to a specific engine build or specification level. For the 4TNE92-HRJ, level (A) is the base engine. Higher letters (B, C, etc.) indicate variations – maybe different injection pump calibration or alternator brackets. When ordering a part, match the lever code from your engine’s data plate to the column in the catalog. Ignoring that step gets you the wrong part. The catalog shows the parts that apply to each lever, so you only order what fits your engine. This is one of the biggest reasons DIY guys screw up – they assume one size fits all. It doesn’t.

Why This 16-Page OEM Catalog Matters

It’s 16 pages – not 160. Every page is packed with essential data. The file name is Yanmar_4TNE92-HRJ_Parts_Catalog_en-25414018070.pdf, straight from Yanmar’s E‑Products division. No aftermarket reprints, no scanned copies with missing pages. You get the exact PDF that the OEM released. The page‑by‑page bookmarks (001.pdf to 015.pdf) make navigation instant. I’ve used these catalogs for years on the shop floor. They save you the phone call to the parts counter when you need a head bolt gasket or a camshaft bush. Get the factory data – it’s the only way to ensure the part fits and lasts.

FAQ – Two Questions We Get a Lot

Does this catalog include torque specs?

No – this is a parts catalog only. You need the separate service manual for torque values.

How do I identify which lever code (A–E) my engine uses?

Look at the engine data plate – usually stamped on the gear housing or cylinder block. The model designation (e.g., 4TNE92-HRJ) correlates to lever A in this catalog. If your engine has a different suffix (like -HRJ2), check the lever column for that letter. If you don’t see your exact variant, call Yanmar with the serial number. The catalog is specific to the 4TNE92-HRJ family, but lever codes distinguish production changes like injection pump type or cooling system variant. Using the wrong lever can give you a part that physically fits but doesn’t match the specs – for example, a different oil pump gear ratio. Always cross-check your engine’s serial with the catalog’s lever information. If you’re still unsure, take a clear photo of the data plate and compare it to the catalog’s remarks. Better to ask than to order twice.

Don’t waste another afternoon chasing the wrong part. Access the Factory Manual – the genuine Yanmar 4TNE92-HRJ Parts Catalog – and have every OEM number at your fingertips. It’s a 16‑page PDF, so it loads fast and prints clean. Stop relying on third‑party listings. Factory spec or bust.
