Komatsu excavators and wheel loaders
We supply parts for PC series tracked excavators and WA series wheel loaders, for example the WA250. On wheel loaders, apart from the engine, the most requested parts are for the transmission (oil pump, clutch plates, seals, bearings) and the hydraulics.
For Komatsu forklifts, send the engine type from the engine plate, because parts are looked up by engine.
Excavator undercarriage
On a tracked excavator, the chains, shoes and rollers wear the most. For an accurate quote, send the number of chain links and the shoe width along with the excavator model and serial number. If you are not sure whether replacement is due, see our guide on when to replace the undercarriage.
What to prepare for your enquiry
- the machine model and serial number from the plate
- the engine type and serial number
- the part catalogue number or a photo of the old part
- for the undercarriage: the number of links and the shoe width
Models
- PC serija
- WA serija
- WA250
Frequently asked questions
Do you have parts for the Komatsu WA250?
Yes, for the WA250 we supply engine, hydraulic, transmission and electrical parts. Send us the machine serial number so we can confirm the version.
What do I need to order an undercarriage for a Komatsu excavator?
The excavator model and serial number, the number of chain links and the shoe width. A catalogue number from the chain or roller is even better.
Do you repair Bosch pumps for Komatsu engines?
Bosch pumps and nozzles are available new or for repair. Send us the marking from the pump plate.
How quickly do Komatsu parts arrive?
Parts in stock ship immediately, and for many groups the lead time is 1 working day.
