I’ve been building and wrenching on dirt bikes since before you were probably born. When it comes to tracking down the correct part number for a Yamaha WR250FP, WR250F Parts Catalog, you don’t want to guess. I’ve watched grown men order the wrong camshaft three times because they trusted a parts website that didn’t cross-reference production codes. This is the real deal: a 71-page OEM Yamaha publication that breaks down every nut, bolt, and gasket on these bikes. If you’re rebuilding an engine or swapping a suspension component, this is the only reference you should touch.
Yamaha WR250FP, WR250F Parts Catalog: Engine Breakdown
You need the right part numbers for the Engine section. This catalog covers Cylinder, Crankshaft (with piston), Valve components, and the Camshaft. The diagrams show exactly how each piece fits together. I’ve used these factory drawings to identify an incorrect oil seal that a previous owner had jammed in. The Crankshaft.Piston section on page [DATA NEEDED] lists each bearing and ring with the Yamaha part number.
Does This Manual Cover the Transmission and Suspension?
It does. The Transmission section includes the shift cam, shift fork, and shift shaft. The Suspension section walks you through the front fork and rear suspension assemblies. If you’re rebuilding a shock or swapping fork internals, you need the OEM part numbers. Aftermarket cross-references are often wrong. I’ve seen a guy order a rear brake caliper seal kit based on a generic catalog, and it didn’t match the WR250F bore. This catalog gets you the correct part.
3 Reasons to Trust This Yamaha Parts Catalog Over Aftermarket
First, it’s printed by Yamaha Motor Co., Ltd. – not a third-party copy that renumbers parts. Second, it includes production code splits: for example, the WR250FP (5PH5) for U49 and the WR250F (5PH6) for Europe have different frame numbers, and this catalog shows you which part fits which. Third, it has a Numerical Index at the back. You can look up any part number and find the page. That saves time when the parts counter guy asks for a number you don’t have.
Fuel System and Carburetor: Parts Reference
The Fuel section includes the fuel tank, graphics, and the carburetor assembly. The Carburetor sub-section lists the pilot jet, main nozzle, and gasket kit – all with Yamaha part numbers. If you’re cleaning or jetting a WR250F carb, having the OEM part numbers lets you order the exact jets without guessing. The manual also covers the radiator and hoses, oil pump, oil cleaner, and intake. The water pump section alone can save you from ordering a wrong impeller.
Get the Right Part Number the First Time
Before you call the dealer or click “add to cart,” open this parts catalog. Look up the part in the exploded diagram, note the reference number, then cross-reference to the part number list. The catalog shows quantity per assembly and any alternate parts (AP) or local made (LM) items. The remarks column tells you which color graphic or which production code applies. If the part has an asterisk (*), it’s a modification after the first edition – important for identifying superseded parts.
I’ve got a stack of aftermarket parts catalogs in my shop that I use only for paperweights. For actual work, I pull the factory OEM publication. This 71-page PDF gives you exactly what Yamaha engineers intended. No guesswork, no wrong orders. Check out related manuals: Yamaha YZF-R1 2002 Parts Catalog – OEM Factory Part Numbers, Yamaha GTS1000AE 1993 Parts Catalog – Factory Microfiche PDF, and Yamaha V125 Parts Catalog – OEM Factory Part Numbers & Diagrams.

- Does this parts catalog include torque specifications?
- No. This is a parts catalog – it lists part numbers, quantities, and illustrations. Torque specs are in the Yamaha service manual, not this document.
- Can I use this to rebuild the engine?
- Yes, for parts identification. You’ll need the part numbers for pistons, rings, gaskets, and bearings. The exploded diagrams show assembly order, but the actual rebuild procedure requires the service manual. This catalog gets you the right components.
- How do I find the part number for the crankshaft?
- Go to the Engine section, then Crankshaft.Piston sub-section. Look for the crankshaft assembly reference number, then find the corresponding part number in the list. The numerical index at the back can also help if you have a partial number.
- Is this a genuine Yamaha publication?
- Yes. It’s a factory PDF of the original Yamaha Parts Catalogue (2A5PH-100E1), published October 2001. It covers the WR250FP (5PH5/5PH8) and WR250F (5PH6) models. No reprints, no generic reproductions.
You need this in your digital library if you own one of these bikes. Download the Factory Manual and stop guessing part numbers.
