3.5 Assembling the Seal Housing
Figure 9.
F
Make sure the grooves and airway of the seal housing are clean
and free from any contaminants (e.g. water, dirt, metal filings, etc.).
F Inspect the seal housing O-rings (supplied) for dirt, damage or
other conditions which might cause leaks.
F 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.
F Lubricate the seal housing running surface on the Air Locker carrier
with oil. Assemble a bearing cup onto the left-hand side of the Air
Locker.
F With the stepped side towards the bearing, carefully install the seal
housing by sliding it all of the way onto the bearing journal with a
gentle twisting motion. This will allow the O-rings to engage gently.
IMPORTANT :
A 4mm Master Shim is supplied for use with the “thin” bearing cup
(382A). Do not use this shim with the “thick” bearing cup (382-S).
