Complaint or Symptom:
Rear wheel disks to axle bolts loosen and
break on the following tire sizes:
11.2-24 4 PR R3 Rear Wheel
14-17.5 6 PR R4 Rear Wheel
11.2-24 4 PR R1 Rear Wheel
15-19.5 6 PR R4 Rear Wheel
12.4-24 6 PR R1 Rear Wheel
Problem:
1. Conical hub bolts loosen during forward
and reverse cycle or hillside operation.
2. Loose hub bolts allow disk holes to
wallow oblong.
3. Current countersunk holes in disk may
not provide adequate hub bolt mating
surface.
NOTE: Symptoms described above are for
the flat disk, not coined disk design.
Solution:
1. Check for stripped threads. Drill and
Helicoil axle tapped holes, if necessary.
2. Replace disk if holes are wallowed.
3. Replace all original hardware with new
bolt and flat washer to provide improved
clamping force.
4. Remove paint from the axle flange and
wheel bolt circle mating surfaces.
5. Replace wheels and tighten wheel to
axle bolts to 154 N • m (114 lb-ft).
6. Wheel bolts should be clean but not
oiled. Oil will decrease friction, allow
more torque and break the bolt.
Parts:
16-LVU12708 Bolt (Wheel to Axle)
16-24M7436 Washer (M14x32x4mm)
2-Wheel (See Parts Catalog)
Additional Information:
Check torque at 10 hour interval for the first
20 hours. Check torque often during the first
100 hours.
