channel seal from

aligned, cover should fit flush on gear housing

(figure 46).

cover and gear housing until threads are started into bearing
housing. Alternately tighten the bolts in increments that will
make the three components pull down evenly

(figure 47).

Torque the bolts in

increments until the bolts

(qty 4)

are

torqued to

200 ft. lbs.

Review all assembly steps to make certain the assembly

is correct. Wipe and clean any grease that may be on the
