Caution: Do not install the Scotseal® directly onto the spindle.

Place the hub (wheel) assembly at a 45° angle for seal installation. This aids in centering the bearing and seal in the hub bore. Clean bore of any particles, rust or grease.

Pre-lube the inner bearing cone with the lubricant that is being retained and place it into the hub.

Place the Scotseal® Classic or Scotseal® Longlife onto the hub bore and insert the tool assembly with centering plug into the seal. Note: Be sure to wear proper eye protection.

Hold the tool handle firmly and straight, and drive the seal with firm hammer strokes until the seal is squarely seated. Continue driving the seal into the hub until the sound of impact changes.

After the seal is bottomed in the bore, check for freedom of movement by manually moving the packing of the Scotseal® Classic or Scotseal® Longlife up and down. The Scotseal® Longlife will have more resistance due to the additional dirt lip.

Ensure that the inner bearing rotates freely.

Caution: Install a new seal if the seal is cocked or damaged during or after installation.
