Gearbox Alignment

3.15 Gearbox Alignment
It is important that the gearbox pulleys are cor-
rectly aligned. If the pulleys are not aligned, it
will result in over-tensioning and premature belt
failure.
To check the alignment of the gearbox pulley,
use a straight edge. The front face of the clutch
pulley should align with the front face of the
gearbox pulley.
If the pulley alignment is not correct, then
loosen the gearbox pulley and reposition it.
After alignment, at least 7/16" of the gearbox
shaft protrudes from the pulley.
Snug up the three bolts (do not tighten) of the split taper bushing, position gearbox and
check that the face of both pulleys are still aligned. Then tighten the hub bolts 1/2 a turn in
sequence till all are tight (100 in-lb torque) and check again.
When the pulley hub is tightened it will normally pull the pulley backwards resulting in the
correct alignment. Now add the two shims to raise the gearbox by 1/16" and reassemble.
Additional gearbox shims may be added if alignment was incorrect.
