Figure 4
. Driveline Installation
1.
Clean input shaft on gearbox and smooth bore of
driveline yoke. Remove any foreign material or
paint. Lightly file any nicks or dents.
2.
Grease the input shaft of the gearbox. This
reduces the chance of the driveline galling the
shaft if the shear bolt should fail.
3.
Slide driveline over input shaft and align cross
holes. Insert shear bolt (3) to hold parts together.
4.
Loosen the jam nut (6) so that it is flush with the top
of the set screw (7, Fig 3.1). Tighten the set screw
against the gearbox input shaft. Once tightened,
loosen the set screw (7) a 1/4 turn. Continue to
hold the set screw (7) in this position while
tightening the jam nut (6). Remove shear bolt (3)
from cross hole. Driveline yoke should spin freely
on shaft.
NOTE:
The set screw prevents the driveline from
coming off gearbox shaft if the shear bolt should
shear.
5.
Secure drive line to input shaft with shear bolt (3),
lock washer (4), and hex nut (5).
NOTE:
Under no circumstances should driveline
adapters be used when attaching driveline to trac
