ASSEMBLY
1. Thoroughly clean the gearbox housing, taking
care to remove all old sealant on cover mounting
flange. Install bearing cups into housing with the
cups facing outwards from bore. Firmly seat
bearing cups against shoulders in housing.
2. Install the shaft seal, 1, into housing so that outer
face of seal is flush with outer face of the housing.
3. Pack a new bearing cone with grease, and press
it onto shaft, seating it against the shoulder.
4. Apply grease to the lip on the shaft seal. Install
the shaft assembly through seal, taking care not
to damage it. Pack a new bearing cone with
grease, and install it over the shaft. Press it down
into bearing cup until the bearing cone is almost
fully seated.

5. Install a gear onto shaft splines, and install a
hardened washer and castellated nut onto shaft.
Tighten the nut to seat the bearing cone into the
cup and obtain 0.45 -- 1.13 N⋅m(4--10in-lb)
rolling torque on shaft.
6. Install other shaft in same manner as the first.
The shaft and gear do not need to be indexed, or
timed to one another. Tighten the nut to seat the
bearing and set the rolling torque on the second
shaft to 0.45 -- 1.13 N⋅m (4 -- 10 in-lb) plus the
rolling torque value obtained on the first shaft, as
per the chart at right.
