(Optional: I did this) Using wheel bearing grease, liberally coat "inside" of outer seal from inside of housing. Carefully lay hub housing on top of hub, with shaft coming through opening. Clean hub/shaft and lay on workbench, shaft side up.Ģ1. Also, coat inner surface of seal with grease.Ģ0. (Optional I did this) Using wheel bearing grease, form a 1/4" of grease around outer seal at inner edge. Using JD seal installer, install outer seal to a depth of 0.060" (see picture on "Installation Instructions" that come with seal.ġ9. wipe a thin coat of sealer on outer hub seal outer surface.ġ8. With solvent, prepare outer edge of outer seal and receiving surface on hub assembly for sealer.ġ7. Separate new two-piece seal and set aside inner part.ġ6. from both mating flanges (on hub assembly and on axle assembly on tractor).ġ5. With brass wire brush, remove old sealer/rust/etc. Carefully tap out outer bearing from assembly (note that it will probably drop out after initial movement).ġ4. Pick up hub assembly and place on workbench, flange side down. Remove inner bearing, gear, and large spacer. When gear is free, everything should drop out at that point.ġ1. Carefully press hub shaft, first through inner bearing, then gear. Put hub assembly gear-side-up in hydraulic press, with hub free to be expelled.ġ0. When the assembly has protruded approximately 1/4", you should be able to wiggle by hand and remove - careful - it is heavy, probably 30 pounds?Ĩ. Carefully break loose hub assembly by alternately tapping recesses at 3 & 9 o'clock positions.ħ.
Run razor knife along groove where flanges meet to break paint/sealer bond.Ħ. Lift tractor wheels off ground, place jack stands under axle.Ĥ. Pressure wash wheels and hubs thoroughly.Ģ.
Parts needed: Seals, John Deere Sealant (TY6304 this is Permatex 515), axle fluid, solvent, wheel bearing grease.ġ. Tools needed: Hydraulic press 10 mm socket for hub bolts, seal installer, depth gauge, brass brush to remove old sealing material from mating surfaces, Allen wrench/socket for axle drain plug, flat-faced chisel, hammer razor knife, large external snap ring pliers, torque wrench. Note that this procedure was done on a 2000 4300 Compact Utility Tractor, but should be generalizable to many other contemporary John Deere models.
