Rebuild/Refurbishment of Cat Dozers
Rebuild/Refurbishment of Cat Dozers
Good morning. We are starting to write specifications for an RFP concerning the rebuild/refurbishment of two Cat 844 coal dozers. Does anyone have a spec we can use to start the process (so we don't reinvent any wheels)? I would appreciate any consideration. Thank you!
