7 Transmission Repair
7C Hydro-Gear 216-3010L
Note: Prior to assembling of the input shaft compo-
nents be sure all old gasket material is cleaned from the
bearing retainers.
11. Install a new lip seal into the upper bearing retainer.
12. Install new O-rings (quad rings) onto each bearing
retainer.
13. Wrap the splines and threads of the input shaft with
cellophane (or equivalent) to protect the lip seal from
damage.
14. Install the wave washer into the upper bearing retain-
er and install the bearing retainer onto the input shaft
assembly. Remove the cellophane.
15. Place the input shaft assembly into the lower bearing
retainer.
Note: The bearing retainers are reversible and inter-
changeable. Take care to position both so that the input
shaft is aligned with the center of the input pinion assem-
bly. Because of the high rpm that these assemblies will
run, any mis-assembly will cause very noisy operation
and rapid failure.

16. Before installing the input shaft assembly, apply a
small amount of the silicon gasket sealant in the
recessed pocket of the left hand housing where the
O-ring on the upper bearing retainer will be posi-
tioned.
