How to read a Weichai part number
Weichai numbers are not random: a long numeric prefix identifies the assembly group, and the remaining digits identify the variant. This is why two numbers that differ by one digit can be different parts - or an updated supersession of the same part. Never substitute on the basis of a similar-looking number; confirm the supersession with us or with the parts list.
Cross-referencing: what to check
- Supersessions: manufacturers replace numbers over time; the old number may still be valid for older builds.
- Engine rating: the same base engine is built in several power ratings with different pistons, injectors or turbochargers.
- Interchangeability: some numbers cover several models (a liner used in two engine families, for example).
- Quality grade: an aftermarket equivalent should match the original material specification, not just the dimensions.
Ordering by part number
- Send the number exactly as printed, including any letter suffix.
- Add the engine model and serial number so we double-check the application.
- State the quantity - one piece is the minimum, container orders get factory pricing.
- Tell us the destination so we can quote FOB, CIF or DDP.
