Yanmar 4JH Parts Catalog – 132 Pages of Factory Specs

If you’ve ever ordered a part for a Yanmar 4JH engine only to get a box that doesn’t fit, you know the pain. I’ve seen it – junior techs chasing a fuel injection pump for three days because they used a third-party parts list. The Yanmar 4JH Parts Catalog ends that. This isn’t a reprint or a scanned copy from some parts store – it’s the factory document, 132 pages, straight from the OEM. Automotive Industry Overview standards change, but Yanmar’s catalog stays accurate because it’s the source.

Yanmar 4JH Parts Catalog: Cylinder Block and Gear Housing Breakdown

Section 1 of the catalog pulls apart the cylinder block. Every bolt, every sleeve, every damper plate has its own part number. The gear housing section (Section 2) is equally precise – no guessing which flywheel housing bolt matches your 4TNE106-TB. You get exploded diagrams with callouts, not just a list. Need the exact crankshaft key? It’s in the cylinder block chapter with an indexed reference.

7 Engine Sections with Individual Parts Indexes

This catalog covers three engine variants: 4TNE106-TB, 4TNV106-NTB, and 4TNV106-NTB1. Each has its own set of sections, but they share the same 19-chapter structure. You get cylinder head and bonnet, suction manifold and air cleaner, exhaust manifold and silencer – the works. Each chapter ends with a numerical index so you can find any part number in seconds. For a broader scope, check the Yanmar TB135 4JH Engine Parts Catalog which adds more variant coverage.

Fuel Injection Pump and Valve: Real Part Numbers from the Factory

Section 13 covers the fuel injection pump, and Section 14 the fuel injection valve. The catalog lists part numbers for multiple 4JH variants: 4JH-B7, 4JH-DTY, 4JH-DTIP, and others. For example, pump part 122470-51040 is called out for 4JH-B7/STY/DTIP. No aftermarket cross-reference hacks – these are Yanmar’s own numbers. The fuel line section (Section 15) ties it together with routing diagrams and clip part numbers.

Does This Catalog Cover the 4TNV106-NTB1 Governor?

Yes. Look at the PDF bookmarks: the 4TNV106-NTB1 section includes a dedicated GOVERNOR chapter. Most aftermarket parts sites skip that detail. Here you get the governor linkage, spring, and lever part numbers with exploded views. If you’re rebuilding a 4TNV engine, this catalog is your single source for all fuel system parts, including the engine stop device (Section 16). That’s the difference between a correct rebuild and a parts run. Yanmar 4JH Engine Parts Catalog also helps if you need a direct link.

Cooling Water System and Radiator: Cross-Reference Codes

Sections 11 and 12 cover the cooling water system and radiator. The catalog shows the water pump, thermostat housing, and radiator core with specific part numbers for each variant. A common mistake is ordering a radiator for the 4TNE106-TB when you have the 4TNV106-NTB – the fan shroud bracket numbers differ. This catalog kills that error because it lists each variant’s cooling components separately. Yanmar 4JH-DT, 4JH Parts Catalog – 223 Pages OEM offers even more coverage if you need additional pages.

Automotive Industry Overview Automotive Industry Overview is a side note, but the takeaway is clear: factory parts catalogs save time and money. Period.

Is this a service manual with torque specs?

No, it’s a parts catalog. It lists part numbers and diagrams, not repair procedures.

How do I find the correct part number for a 4JH-B7 fuel injection pump?

Turn to the Fuel Injection Pump section. The catalog lists multiple variants: 4JH-B7, 4JH-DTY, 4JH-DTIP, etc. Each has its own part number prefix. For example, part number 122470-51040 is listed for 4JH-B7/STY/DTIP. The exploded diagram shows exact positioning. If your engine serial number matches, you can order with confidence. The catalog includes a numerical index at the back to cross-reference any part quickly.
