I just had the bobcat repair guy helping me put on my new replacement track and doing the 250hr service and the conversation turned to the timing chain. It turns out that my machine has a Deutz engine and when the chain breaks it bends all the rods. So a relatively easy repair becomes a full day repair in the feild and more parts. He mentioned possibly replacing at 1500hrs , but he also said the machine might go another 2000hrs with no problems. The loader I have has @1340hrs. Any comments or experience would be appreciated.
