PROBLEM

Show/hide table

The existing axle differential 096-8056 Spring Pin can fail on certain M313D, M315D, M316D, and M318D Wheeled Excavators. The initial indication of a failure is typically a noise from the differential. If not addressed, additional and more severe damage to differential gears and housing can result.
