red-diesel ยท 2020-11-29 12:22

have done all the tests and I'm finally at the track motor. No ceased track rollers so I'm going to pull the final drive down. Has anyone got any writeups on the final drive and motor so I could study before pulling down TIA

    Don't know what tests you've done, but first suspect on an excavator is always the swivel seals bypassing?

    Good day Have you checked the following - planetary transmission for lube conditions - marked one trackpad each side compare rotation speed - try dead ending the bucket see if the tracks straighten out. Follow up with more information shortly regards Uffex

    Missed make sure the pedal is clear of debris - Idler not binding - be sure that the arm - boom bucket speed is up to spec.
