10. Remove left housing half and clean housing ange
surfaces on both halves, making sure not to nick or scratch
ange face. Place a 1/8” bead of Dow RTV732 sealant or
equivalent on ange face (make sure RTV is placed around
bolt holes and inside of ange face). Place left housing half
into position and tap with a soft hammer (rawhide, not lead
hammer) until housing bolts can be used to draw housing
halves together. Torque housing bolts per torque values
listed in Table 12.
11. Install input seal, output seals, and auxiliary seals. Extreme
care should be used when installing seals to avoid damage
due to contact with sharp edges on the input shaft or
output hub. The possibility of damage and consequent
oil leakage can be decreased by covering all sharp edges
with tape prior to seal installation. Lightly coat the seal
lips with Mobilith AW2 All-Purpose grease or equivalent.
Seals should be pressed or tapped with a soft hammer
evenly into place in the reducer housing, applying pressure
only on the outer edge of the seals. A slight oil leakage at
the seals may be evident during initial running, but should
disappear unless seals have been damaged.
12. Install bushing backup plates and snap rings on Taper
Bushed reducers or hub collars on straight bore reducers.
