This John Deere gator clutch had a manufacturing defect that needed a quick fix. The internal tapered bore that fits the end of the crankshaft wasn’t machined deep enough to fit the crankshaft properly. Some quick indicating of the bore and taper and this clutch is ready for service.

After a thorough inspection and rebuild of the cylinder has been conducted, our friends at Treska Bros. Excavating & Trucking LLC are now equipped to continue their digging activities. We extend our gratitude to R&D Metal Fabrication for their expertly crafted custom wrench, which facilitated the efficient removal of the piston nut.
