HP Seal

Installation

Step 1 Remove all burrs from the hub bore and spindle.

Thoroughly clean the entire wheel cavity. Apply a thin

layer of No. 2 sealant to the OD of the spindle shoulder.

Place the seal assembly on the spindle so the words

“Oil Bearing Side” are exposed to the oil. [Photo 1]

WARNING: Do not install the seal into the hub bore.

Step 2 Using the recommended Stemco Universal Axle Tool,

drive the seal assembly on until the tool bottoms

against the shoulder. [Photo 2] Make sure the ring is

flush with the shoulder. Wipe away any excess sealant.

Step 3 Dip the inner bearing in oil and place on the spindle.

NOTE: The OD of the seal must be coated with a thin coat

of oil. NOTE: When using grease, pre-pack the inner

bearing before placement into the hub.

Step 4 With the wheel mounted on a wheel dolly, carefully

push the wheel onto the spindle until it contacts the

seal. [Photo 3] Dip the outer bearing in oil and place it

on the spindle. NOTE: When using grease, pre-pack the

inner bearing before placement into the hub. Tighten the

inner spindle nut hand tight and remove the wheel

dolly.

Step 5 Tighten the inner nut to 200 ft/lbs. [Photo 4] Rotate

the wheel several times and then back-off nut one full

turn. Make final bearing adjustment according to TMC

recommended bearing adjustment procedure. Install the

appropriate axle fastener.

Step 6 Install the hub cap with a new gasket and fill the

cavity with lubricant until the proper oil level is

indicated on the window. On drive axles, be sure the

differential oil level is high enough (manufacturer’s

recommended level) to ensure oil flow through the tube

to the wheels. It is recommended to jack-up one side

and then the other until flow starts. Make certain the

breather plug is clear. Recheck steers and trailers to

insure proper fill levels.
