18.37.Clean and inspect the input shaft.
NOTE: Check the bearings for looseness and
smoothness of rotation.
NOTE: Check the profile of the teeth on the
sprocket, particularly if the chain is to be
replaced. If worn, the sprocket and shaft must be
replaced.
NOTE: Check the gear teeth and splines for
abnormal wear.
NOTE: Check the condition of the engagement
dogs on the sprocket, gear, and shift collar.
NOTE: If the engagement dogs are damaged,
the shift rod or shift interlock mechanism may be
out of adjustment.
NOTE: The gear and sprocket ride on caged
needle bearings. If the needle bearings are worn
the engagement dogs will not align properly. Dif-
ficult shifting and damage to the engagement
dogs will result.
NOTE: A detent spring and ball reside in a bore
in the input shaft. Make provision to capture
them if the shift collar is removed from the input
shaft.
18.38.Lubricate all contact points with assembly lube
or universal (hydraulic) tractor transmission fluid,
and assemble the input shaft using new compo-
nents where required.
18.39.Remove the shift arm.
18.40.Remove the input shaft seal from the left trans-
mission housing.
18.41.Remove the differential lock shaft seal from the
right transmission housing.

housings. Remove all traces of old sealant from
the sealing surfaces. Remove all traces of old
transmission fluid from the inside of the hous-
ings.
NOTE: The use of abrasive cleaning wheels is
not recommended.
NOTE: Look for cracks, worn bores, stripped
threads, damaged sealing surfaces. Minor dam-
age can usually be repaired. Stripped threads
may be repaired with inserts.
18.43.Install a new o-ring seal on the shift arm.
NOTE: Lubricate the seal with assembly lube or
universal (hydraulic) tractor transmission fluid.
