WHEEL BEARINGS

Type of Grease: Use a good grade of Lithium Base Wheel Bearing Grease.

Carefully raise and support each wheel as repacking and adjustment is performed.

Remove the hub from the spindle. Inspect the inner and outer cups in the hub. Be

sure both cups are seated against the shoulders in the hub.

Pack the cones with grease. A pressure grease packer is recommended. To hand

pack cones, force grease under cage between rollers from large end of rollers until

grease shows at small end. Fill the hub with grease to I.D. of the cup race, then

place the cone into the cup. Make sure the cone is straight!

WARNING: Failure to correctly lubricate bearing and maintain proper

lubrication may result in bearing damage which could cause wheel to lock

and come off during operation.

Install grease seal. Support the seal so as not to bend the case during installation.

Use grease to lubricate the seal lip.

Place the hub on to the spindle. Rotate the hub while doing this so that the seal lip

does not fold under as the lip goes on the seat of the spindle.

Fill hub cavity with grease.

Place the outer cone on the spindle and into the cup.

Assemble the washer and nut onto the spindle and tighten the nut to 15-20 ft/lbs,

while rotating the hub. back off the nut until it aligns the next available slot with the

cotter pin hole. Install the cotter pin and bend around the nut. There should be

between .001" - .005" end play.

WARNING: Failure to back off adjusting nut may cause bearing to run hot

and be damaged. Wheel could then lock and come off during operation.

Grease inside of dust cover and install dust cover.

Lower the wheel to the ground and repeat for the other wheels.
