Guangxi Yuchai Machinery YC6J245-30 Parts Catalog

If you’ve ever stood in front of a Guangxi Yuchai Machinery YC6J245-30 with a blown gasket and had to guess the part number because some aftermarket PDF showed a different assembly, you know the kind of waste I’m talking about. Time, money, and the wrong parts sitting on the bench. This Parts Catalog is the original factory document – 74 pages of exploded diagrams and OEM part numbers for the YC6J245-30 (J61LA) diesel engine. No aftermarket interpretations. No cross-referencing guesswork.

What’s Actually Inside the YC6J245-30 Parts Catalog?

Open the table of contents and you’ll see 32 major assemblies. Start with the cylinder block assembly (page 3), then gear housing, cylinder head and cover, piston and connecting rod, crankshaft vibration damper, camshaft, valve train, intake and exhaust manifolds. Each section has a clear diagram and a parts list with the Guangxi Yuchai part numbers. The catalog covers the fuel supply lines, fuel filter, injection pump and injector, turbocharger, water pump, thermostat, alternator, starter, and the control system. You get 74 pages of factory spec data – not a reprint, not a scanned copy from a third party.

Cylinder Block Assembly and Gear Housing Parts

Start with the J5600-1002000 cylinder block assembly diagram. It shows 42 individual components – from the block itself down to the dowel pins and plugs. The gear housing section lists the timing gear train parts. If you need to order a new camshaft gear or idler gear, you get the exact Guangxi Yuchai part number. No need to call the dealer and describe what you see. The diagram tells the story.

Cross-Reference Part Numbers the Right Way

Don’t trust aftermarket catalogs that list generic numbers. This manual gives you the factory part numbers used by Guangxi Yuchai Machinery. For example, the J5600-100400 piston and connecting rod assembly, or the J5600-100500 crankshaft vibration damper. When you order using these numbers, you get the correct part the first time. I’ve seen too many guys slap in a piston that looked right but had the wrong pin height. That’s a rebuild you don’t walk away from proud.

74 Pages of Factory Exploded Diagrams

Each assembly page has a numbered diagram with a corresponding parts list. The oil pump assembly, oil cooler, crankcase ventilation, dipstick – all covered. The steering pump and air compressor sections are included too. If you’re working on a YC6J245-30 in a truck or generator set, you need these diagrams to identify what’s in front of you. The catalog even includes the control system section (J5600-382300) for the engine management components. That’s information you won’t find in a generic engine manual.

Turbocharger and Fuel System: OEM Diagrams

The turbocharger assembly (J5600-111800) diagram shows the turbine housing, compressor wheel, and oil lines. The injection pump section (J5600-111100) lists the pump body, plunger, and delivery valves. Fuel supply lines (J5600-110400) are shown routed with all brackets and clamps. When you need to replace a high-pressure line, one wrong bend and you’ve got a fuel leak. The diagram shows the exact path. Follow it.

FAQ – Guangxi Yuchai YC6J245-30 Parts Catalog

Does this catalog cover repair procedures?

No. This is strictly a parts identification manual – diagrams and part numbers. You need a service manual for torque specs and assembly steps.

What engines does this catalog apply to?

Only the Guangxi Yuchai YC6J245-30 (J61LA) diesel engine. Not YC6J210 or other variants.

Can I use these part numbers for a YC6J245-30 in a different vehicle?

The catalog covers the base engine. Some vehicle-specific components like the alternator bracket or fan may vary – but the long block and major assemblies are the same. Cross-check with the vehicle manufacturer’s manual if you’re unsure.

How do I read the exploded diagrams in this catalog?

Each assembly page shows a numbered diagram. The parts list below gives the item number, factory part number, description, and sometimes a quantity. For example, the cylinder block assembly on page 5 lists item 1 as J5600-1002000 – the cylinder block itself. Item 2 is the cylinder liner, etc. The diagram is from the perspective of the engine – front, side, or top depending on the assembly. Match the exploded view to the actual engine layout. If a part is shown in the diagram but not listed, check the next page – some assemblies continue across multiple pages. The catalog is split into 32 sections, each starting with the assembly number. Bookmark the ones you use often – the turbocharger and fuel system are common call-outs.

Don’t waste another afternoon chasing down the wrong part. Access the Factory Manual and get the OEM part numbers you need. This is the original Guangxi Yuchai document – 74 pages of part numbers and diagrams that match the engine on your stand.
