22.To install brake disks, first install a stator, then a rotor
(hub to inside), then a stator, then a rotor (hub to
inside), then two stators.
23. Install the brake bolt (with nut) into the upper housing.
At this time make sure the pump and motor rotate
freely. Also check that the bypass actuator lifts the
motor off the center section.
24.Apply sealant as shown in the example.
NOTE: The drawing may not be the same as the original
factory sealant application, but is the currently recom-
mended pattern. Apply sparingly.
NOTE: Use RTV or silicone sealer. Do not put sealant
over lip seals.
25.Position the lower housing on the upper housing and
secure with capscrews. Torque capscrews to 135-
165 in-lbs. in the sequence shown in Figure 36.
26.Wipe off all excess sealant from the seam of the
housings.
27.Check the bypass actuator and axle shafts for free-
dom of movement. The axle shafts should not lock up
but may rotate stiffly. The bypass actuator shaft must
rotate freely.
32.Install the bypass actuator shaft and control shaft
seals by applying petroleum jelly to lip of seal, and
wrapping the sharp edge of shaft with plastic tape.
Press the seal into case using a driver which only
applies force to the outside edge of the seal.
33.Install the bypass valve actuator arm and retaining
ring on the bypass shaft. Use care to avoid over-
extending the retaining ring.
