Hub-Seal

Installation

Step 1

Remove all burrs from the hub bore and spindle.

Thoroughly clean hub cavity and spindle.

NOTE:

Do not apply

any sealant to the spindle

shoulder.

Step 2

With the wheel in horizontal position, pre-lube the

inner bearing and place it into the bearing cup.

NOTE: When using grease, pre-pack the inner

bearing before placement into the hub.

Step 3

Place the seal on the recommended Stemco Installation

Tool, with the correct head, so that the words “Air Side”

face into the tool. Place the tool (with the seal correctly

mounted in the tool head) over the hub bore. Use a 3 to

5 pound hammer to drive against the end of the tool.

Drive seal into bore until complete bottoming is assured.

Remove Tool. Apply a thin layer of lubricant

on the ID surface of the seal.

NOTE:

Do not apply

lubricant to the OD of the seal.

Step 4

With the wheel mounted on a dolly, carefully align the

bore with the spindle.

Gently push the wheel

assembly onto the spindle to the proper position. Fill

the hub cavity with lubricant until it runs over the

outer bearing cup. Coat the outer bearing with lubricant

and place it on the spindle and into the bearing cup.

NOTE: When using grease, pre-pack the outer bearing

before placement into the hub.

Step 5

Assemble the inner nut and tighten it to 200 ft/lbs.

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 to the proper level. 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.
