Weichai Huafeng Power 495, 4100 Parts Catalog

If you’ve ever ordered a piston ring set for a Weichai Huafeng Power 495, 4100 Parts Catalog diesel engine and ended up with the wrong compression height, you know the frustration. Aftermarket catalogs mix up revisions, skip updates, and give you part numbers that lead to dead ends. This OEM parts catalog from Shandong Weichai Huafeng Power Co., Ltd. stops that nonsense. 90 pages of exploded diagrams, reference numbers, and factory part designations for the 495 and 4100 series. No translation errors – it’s bilingual Chinese/English. You get the same document the dealer uses to order a camshaft or a crankshaft. That means you order exactly what came off the assembly line.

CYLINDER BLOCK ASSEMBLY (FIG. 1–FIG. 2): Why This Section Matters

Pages 1 through 14 cover the cylinder block and its components. You get two figures – the block itself and the associated hardware like liners, main bearing caps, and plugs. The table on page 3 lists every part with its OEM number, description, and quantity per engine. If you’re rebuilding a 4100, you need to know which main bearing set fits. This section gives you that without cross-referencing three different aftermarket sites.

CAMSHAFT ASSEMBLY (FIG. 3): Valve Train Parts at Your Fingertips

Page 15 shows the camshaft assembly figure. The table on page 16 lists camshaft itself, bearings, thrust plate, and timing gear. On the 495 and 4100, the camshaft gear is a separate part – don’t assume it’s included with a new cam. This catalog tells you exactly which gear part number matches your engine series. That saves you a return shipping fee and a week of downtime.

CRANKSHAFT AND FLYWHEEL ASSEMBLY (FIG. 6): Critical Rotating Assembly

Beginning on page 26, you get the crankshaft, flywheel, and related components. The figure shows the crank with counterweights, pilot bearing, and flywheel ring gear. The table on page 27 lists the crankshaft part number specific to the 495 and 4100 – they are not interchangeable. Flywheel bolt sets are also listed. If you’re swapping a flywheel, you have the OEM fastener specifications right there.

90 Pages of OEM Part Numbers – No Aftermarket Guessing

90 pages. That covers 23 assembly groups: cylinder block, camshaft, cylinder head, piston and connecting rod, crankshaft and flywheel, cooling system, air intake, exhaust, lubricating oil system, oil pump, fuel system, air compressor, electrical system (two sections), clutch and power take-off, base frame, clutch assembly, turbocharger and its lubricating oil system, and two turbocharger sub-assemblies. Every figure has a corresponding table with part number, name, and specification. If you need a part for the HIA turbocharger sub-assembly, it’s on page 82–83. No flipping through generic catalogs.

Who Should Buy This Parts Catalog?

DIY mechanics and equipment owners running a 495 or 4100 in a tractor, generator set, or irrigation pump. If you’re a shop owner in San Antonio who sees these engines on Chinese-built equipment, this catalog is your parts lookup bible. Beginners can use it too – the exploded diagrams show exactly how each assembly goes together. But understand: this is a parts catalog, not a service manual. It won’t tell you torque specs or clearance values. For that, get the Weichai Huafeng Power 495 2006 Operators Manual – OEM Factory Specs. For a wider view of the 4100 variant, see the Weichai Huafeng Power R Series Diesel Engine Parts Catalog. And if you’re working on older equipment, the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide might share some fastener patterns – but verify, never assume.

Source Validity – OEM from Shandong Weichai Huafeng Power

This is a direct factory PDF, scanned from the original Chinese publication approved by Chen Ling in 2006. The preface states it’s compiled by Zhao Rui-an, Wang Lu-hai, Ji Xing, Wang Ai-mei, and Jiang Bo. It covers typical cases of the main products in the 495 and 4100 series. The catalog warns that the engine may be modified from time to time, so always verify your engine serial number. But this is the most authoritative parts source short of calling the factory. Aftermarket catalogs that claim to cover “Weichai Huafeng Power” often mix up 495 and 4100 parts or omit the turbocharger sub-assembly. This one does not.

For background on how these engines differ from traditional designs, read this Wikipedia article on diesel engines. If you’re adapting a Power Steering Systems pump to the engine, you’ll need the correct mounting bracket – the parts catalog lists it under the base frame assembly on page 73.

Is this a repair manual with torque specs?

No. It is a parts catalog. You get part numbers, quantities, and exploded diagrams. Torque values, clearances, and repair procedures are in the corresponding service manual.

Does it cover both the 495 and 4100?

Yes. The catalog covers both series. Some parts are common; others are specific. The tables include a column for which engine model the part fits. Check the table notes.

How many pages and what language?

90 pages. Bilingual Chinese and English – headings and tables are in English, with Chinese descriptions. The exploded views use numbered callouts that reference the English tables.

Can I use this to rebuild a 4100 engine from scratch?

Only for ordering parts. You need the service manual for disassembly, inspection, and assembly procedures. The parts catalog tells you what to buy; the service manual tells you how to put it together. Pair it with the operator manual for daily maintenance.

Stop wasting time cross-referencing bad aftermarket data. Get the OEM part numbers straight from the source. Access the Factory Manual now and keep your 495 or 4100 running on factory-specified parts.
