(Step A-41)
(41) Install the speedometer drive assembly and the retainer.
(Step A-42)
(42) Apply a thin film of RTV sealant to the cover plate mating
surface. Install the 4 bolts that hold it in place and tighten
firmly.
We do not recommend using the stock gasket
in this location.
On occasion we have found this gasket
to slip out of position and cause a serious leak.
(Step A-43)
(43) Clean and apply a bead of RTV black silicone sealant to
about the middle of the spline area and slide the rear drive
shaft flange into position. Install the retainer nut and torque
to 90 ft./lbs. Using a chisel and hammer, fold the lip of the
nut to lock it in place.
(Step A-39)
(39) Insert the rear drive shaft flange. This will center the cases
on the seals in the rear tail extension. Use assembly lube
where seal rides on driveshaft flange.
(Step A-40)
(40) Now, with the seals centered on the rear shaft, torque the
bolts to 34 ft./lbs.
(Step A-37)
(37) Replace the outer seal in the rear tail housing. Apply a thin
film of assembly lube to sealing lip of seal.
(Step A-38)
(38) Apply a
few thin dabs
of silicone gasket seal-
ant to the rear tail ex-
tension gasket and
position the rear tail
extension. Apply Loc-
tite 242 to the threads
and install
loosely
the
7 bolts that retain the
tail extension with a 14mm socket. You will also tighten
these later, after the centering of the case is performed.
