19. Some fan clutches were assembled with an external snap ring that is used as a spacer between the bearing
and the oil seal. Newer models were assembled using a notched spacer. If an external snap ring was used,
place snap ring (12) on top of the bearing (oil seal side). If a notched spacer was used, the spacer will be
installed in a later step. Proceed to the next step.

20. Coat the outside diameter of rear oil seal (10)
with Loctite Primer N and #242 (or equivalent).
Use tooling (E) or an equivalent to install the oil
seal in the rear bearing retainer until it is flush
with the rear face.
Do not lubricate the seal. The seal is made of
teflon and must be installed dry.
