Rebuild/Refurbishment of Cat Dozers

 

Rebuild/Refurbishment of Cat Dozers

Submitted by Anonymous

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!
