STEMCO PRO-Torq Instructions

 

Step 1: Remove the Keeper from the nut

Use a small screwdriver to carefully pry the keeper arm from the undercut groove on each side until the keeper is released.

 

Step 2:

Thread the nut onto the axle until hand tight against the bearing

 

Step 3: Seat the Bearing  With hub/drum only:

Using a torque wrench:

1. (1) Tighten the Nut to 200 ft-lbs. Spin the wheel at least one full rotation.

• Tighten the Nut to 200 ft-lbs. Spin the wheel at least one full rotation.
• Tighten the nut to 200 ft-lbs. B. Back the nut off until it is loose.

With hub/drum/wheels:

1. Tighten the nut to 200 ft-lbs while the wheel is rotating.
2. Back the nut off until it is loose.

 

Step 4: Adjust the Bearing  With hub/drum only:

Using a torque wrench:

1. (1) Tighten the Nut to 100 ft-lbs. Spin the wheel at least one full rotation.
   • Tighten the Nut to 100 ft-lbs. Spin the wheel at least one full rotation.
   • Tighten the nut to 100 ft-lbs.
2. Back the nut off one raised face mark.

With hub/drum/wheels:

Using a torque wrench:

1. Tighten the nut to 100 ft-lbs while the wheel is rotating.
2. Back the nut off one raised face mark.

WARNING! Failure to follow this instruction could cause the wheel to come off and cause bodily injury. Failure to back off the nut will cause the bearing to run hot and be damaged.

 

Step 5: Install the Keeper

ORANGE SIDE FACING OUT

1. Insert the keeper tab into the undercut groove of the nut and engage the keyway tang in the axle keyway. Insert keeper tab with the orange side facing out. B. Engage the mating teeth.
2. Compress and insert the keeper arms, one at a time, into the undercut groove with a small screwdriver. NOTE: Recommended practice is to replace the keeper each time the Pro-Torq nut assembly is removed for maintenance purposes.

 

Step 6:

If the inner tang does not line up with the keyway, back the nut off slightly until it does. Using a small screwdriver, compress and insert the keeper arms, one at a time, into the undercut groove. The orange painted side of the keeper must be facing out

Step 7:

Failure to follow this instruction could cause the wheel to come off and cause bodily injury. Make sure that the keeper tab and keeper arms are fully seated into the undercut groove.

 

Step 8:

Inspect keyway tang to ensure it does not contact the bottom of the keyway. If contact exists, immediately notify your PRO-TORQ® representative. Step 9: Acceptable End Play

The dial indicator should be attached to the hub or brake drum with its magnetic base. Adjust the dial indicator so that its plunger is against the end of the spindle with its line of action approximately parallel to the axis of the spindle.

Grasp the wheel or hub assembly at the 3 o’clock and 9 o’clock positions. Push and pull the wheel-end assembly in and out while oscillating the wheel approximately 45 degrees. Stop oscillating the hub so that the dial indicator tip is in the same position as it was before oscillation began. Read the bearing end-play as the total indicator movement.

*Acceptable end-play is .001” – .005”

Please refer to TMC RP 618A “Wheel Bearing Adjustment Procedures”
