Hi everyone, I'm working on an Hitachi EX200 Excavator. The front idler bearing has collapsed and before I go any further I'm wondering how to dismantle it. It requires new bearings and the shaft is badly worn (flat on front side). Would really appreciate any advice on how to dismantle the idler and fit new bearings and shaft. Dave
Dave Not worth rebuilding, try after market or used.
May be this may help Regards Uffex
Great picture of the Idler! Makes the problem easy to understand.
