B-Series Front Drive Axle Disassemblyand Assembly ProcedureThis is a front drive axle from a B5100-DT tractoras seen from the front. Basically this axle is similarto the B6000, B6100 and B7100 units.The major difference between this axle and theother B-Series axles is the method of retaining the pinion gear in the differential. This B5100 unit usesa large snap ring whereas the other units use a triangular retaining plate held in with three bolts.Remove the tie rod ends using Kubota Tool#07916-06021.Remove the front wheel gear case retaining boltsand tap off the gear case covers. If the large drivengear hangs up on the upper outboard bearing, carefully drive the lower inboard bearing approximatelyhalf the way offf the axle shaft as shown in thisphotograph. This will allow the driven gear to clearthe upper outboard bearing.
