to crossmember positioning.
8A. V-Rod Pinion Plate Replacement
1.
With the vehicle unloaded and/or trailer disconnected
on a level surface, chock the front tires to prevent the
vehicle from rolling forward or backward.
Support the frame with jack stands (Figure 12).
2.
Failure to properly support the vehicle
prior to commencing work could create
a crush hazard which, if not avoided,
could result in death or serious injury.
3.
Using a floor jack support the axle at the axle bowl and
block the axle to prevent it from rotating when the bolts
are removed from the frame crossmember assembly.
Failure to properly support the vehicle
prior to commencing work could create a
crush hazard which, if not avoided, could
result in death or serious injury.
4.
Exhaust all air from the system by disconnecting the link
from the lower connection of the height control valve
and pulling down on the link (Figure 18). Refer to
the height control valve manufacturer's instructions for
further information.
5.
Remove the rear V-Rod attachment bolt from the upper
axle bracket (Figure 19). Make sure the two (2) spacer
washers that are between the inside faces of the upper
axle bracket and the V-Rod do not fall out.
6.
Remove the two (2) pinion plates from each side of the
axle bracket (Figure 19). These may be tack welded in place.
They may require grinding out the tack weld to remove.
IMPORTANT: Exercise care when grinding off welds.
Grind weld material flush to the base
material. DO NOT damage the upper axle
bracket material. Rear V-Rod attachment
bolt will hold the plate in place making it
unnecessary to re-weld new plates.
7.
Determine the correct pinion angle from the OEM for the
axle being serviced and obtain the correct pinion plates
for desired pinion angle. Refer to Section 4 table notes
under SRK-683 and SRK-645 for correct pinion plate
part numbers.
