3.6 Installing the Seal Housing
c Make sure the grooves in the seal housing and the surface of the
bearing journal are clean and free from any contaminants (e.g.,
water, dirt, metal filings, etc.).
c Generously lubricate the O-rings with oil prior to assembly, then
insert them into the grooves of the seal housing.
NOTE : When assembling the O-rings, be careful not to leave
them twisted when seated in the grooves as this could
cause excessive wear and leakage.
c Install the seal housing by carefully sliding it onto the bearing
journal with a gentle twisting motion. This will allow the O-rings to
engage gently.
c The notch in the seal housing must be lined up with the threaded
hole on the bearing cap to allow the locking tab to be installed
correctly (Fig.9.). Rotate the seal housing accordingly.
Figure 9.
c Using a small screwdriver or hex key, line the threaded holes on
the clamping plate up with one of the internal notches in the
adjuster nut and one of the holes in the seal housing. (Fig.10.)
