Tightening Instructions for 517 & 511 Hubs
Proper setting for the tapered roller bearings is described in the following procedure. Always use a new cotter
pin when making adjustments to the hubs.
1. Tighten the castle nut to 20 ft-lbs while turning hub. Then back the nut off 1/2 of a turn. Spin the hub 2 or 3
times. While slowly turning hub clockwise, finger tighten the castle nut until castle nut notch lines up with
hole in axle. If notch will not line up, back off nut to next notch.
2. Put the cotter pin in the axle hole. Before bending the cotter pin, spin the hub. The hub should free wheel
from 1 to 2 full turns.
3. If the hub spins the right amount, finish installing the cotter pin by bending the ends.
4. Coat the inside of the dust cap with a thin coat of grease by using your finger. Then install on hub using the
right dust cap driver.
5. Wipe off all excess grease from hub and axle.
There should not be any drag noticed when spinning a tire installed on a hub. If the axle nut
is too tight, the rollers of the wheel bearings will remove the grease from the bearing races,
decreasing the life of the bearings.
WALKING AXLES
Ensure all walking axles are routinely greased.
Always wear protective gloves when handling grease.
TIRES
Periodically check tire pressure. Aircraft tires should be inflated to 42 PSI.
Check tightness of wheel nut, 1/2” wheel nuts should be torqued to 85 ft. lbs.
To remove tires for repair or replacement, install the center transport lock pin. Relieve hydraulic pressure Shut
off tractor, apply parking brake and disengage PTO. Loosen the wheel bolts with wrench. DO NOT remove
them. Use a hydraulic jack to lift the back end of the cutter frame near the wheel standard. Securely block the
wheel standard so the tire can spin freely before removing the wheel bolts.
AVOID PERSONAL INJURY. DO NOT work under cutter without support blocks to keep the
frame from falling.
