7. When driveshaft alignment is correct, tighten fasteners to secure front axle
to frame.
Do not overtighten jam nut for transmission anchor as driveshaft
alignment will be affected.
8. Tighten upper jam nut (item 8 in
anchor and then tighten locknut below transmission anchor.
Ensure that the driveshaft alignment is correct before installing
driveshaft.
1. Insert coupling spacers (item 5 in
Secure rubber couplings to driveshaft with conelock nuts and bolts. Tighten
so that the spacers are tight against driveshaft.
2. Insert coupling spacers (item 8 in
driveshaft assembly to engine and pump hubs.
3. Secure rubber coupling to engine hub with bolts (item 12 in
lock washers, and flat washers. Tighten bolts so that the spacers are tight
against flat washers.
4. After attaching driveshaft to pump hub, ensure that neither rubber coupling is
deformed more than 6.4 mm (0.250 inch) in either direction. If necessary,
remove square-head screws from pump hub. Reposition hub on shaft until
coupling deflection is less than 6.4 mm (0.250 inch). Apply Loctite #242 (or
equivalent) to threads of square-head screws. Install screws into hub and
torque to 9.0 to 11.3 N∙m (80 to 100 in-lb).
5. Secure rubber coupling to pump hub with conelock nuts (item 2 in
flat washers, and bolts. Tighten bolts so that the spacers are tight against
flat washers.
