I am in desperate need of a service manual for my Komatsu PC 112-u excavator. Free, reasonable cost or pay for a photocopy even.

May need to pay for service - ask when you look for replacement fan pump.

Hi Gervin:
Your question appeared in the Washing Machines sections.
A Komatsu log loader would make one wild clothes washer, although somewhat overpowered.
- My excavators have the year stamped in the I.D. plate next to the serial number.
- If you can't find it I would suggest that you contact your nearest Komatsu dealer and ask them.
Cheers.
