How Tight do you Tighten front wheel bearings?
Tighten the nut so that it is verifiably firm, but not overly tight. To check this, look at the notches on the nut. The nut itself will have notches in it on the ends. You will also see on the axle that there will be a hole going through it.
What happens if you over Tighten axle nut?
An axle nut that is too tight will put too much preload on the hub bearings thus diminishing their life expectancy.
How is nut torquing and back-off used to set wheel bearings?
1. Torque the adjusting nut to 200 lbf-ft to seat the bearing components. Always rotate or oscillate the wheel while torquing the adjusting nut to ensure that the rollers are fully seated against the cone large rib. 2. Back off the adjusting nut one full turn or until it’s loose.
How much torque do you put on wheel bearings?
They’re snugged up with no more than 15 to 20 ft. lbs. of torque while rotating the wheel to make sure the bearings are seated. The adjustment nut is then loosened 1/6 to 1/4 turn, and locked in place with a new cotter pin.
When do you tighten the front wheel bearings?
The principle is that you tighten up the inner nut (forget all that torque stuff for now) in order to bed the bearings in. What is important is the rotating of the wheels when the nut is tight. I would tighten in stages spinning the wheel as I go back and forth to get them really settled.
What should the adjusting nut be torqued to?
Torque the adjusting nut to 200 lbf-ft to seat the bearing components. Always rotate or oscillate the wheel while torquing the adjusting nut to ensure that the rollers are fully seated against the cone large rib. 2. Back off the adjusting nut one full turn or until it’s loose. 3. This is where you actually establish end play.
What are the torque specs for the wheel bearings?
- seal contact surface and hub bore.
- (2) Install brake rotor shield to the knuckle.
- (3) Install hub bearing and axle shaft assembly or axle shaft into the housing and differential side gears. Avoid damaging the axle shaft oil seals in the axle housing.
How do you adjust front wheel bearings?
Put one hand on each side of the front wheel hub and push it back and forth between the forks. Noticeable lateral movement signifies the need to adjust the preload. Before making adjustments, spin the wheel easily and let it rotate. Ideally, the wheel should slow and stop in a relatively short time.
What is bearing torque?
Bearing Torque. Bearing torque is the moment required to overcome internal friction to start or maintain rotation of one ring while the other is stationary.
