Tightening Instructions for 511 & 517 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 foot pounds 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 gloved finger. Then install on hub using
the right dust cap driver.
5. Wipe off all excess grease from hub and axle.
IMPORTANT:
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.
Tires
Periodically check tire pressure. Tires should be inflated to manufacture’s suggested specifications. Higher
pressures may cause excessive bouncing over rough ground. Lower pressures may cause excessive wear.
To remove tires for repair or replacement, securely block the frame. Relieve hydraulic pressure
Shut off tractor, apply parking brake and disengage PTO.
WARNING!
AVOID PERSONAL INJURY. DO NOT work under windrower without support blocks
to keep the frame from falling.
Shear Bolt
In order to protect the driveline against excessive shock loads a shear bolt is provided on the universal joint
assembly between the gearbox and chain case. Should the shear bolt break during operation replace with a bolt
of the following specification:
M8 x 45 mm bolt grade 10.9. with interfering type lock nut.
If possible use original equipment shear bolt part #341-4015.
IMPORTANT:
Tighten nut only enough to draw the shear plates together. Do not over tighten the nut. Normal
wrench torques to not apply. Occasionally apply grease to the shear plates.
IMPORTANT:
Replacement of the shear bolt with one of any other grade or size will be considered unauthorized
modification and warranty will be void.
