3.6 Assembling the Seal Housing
Figure 12.
c Make sure the grooves and airway of the seal housing are clean
and free from any contaminants (e.g. water, dirt, metal filings, etc.).
c Inspect the seal housing O-rings (supplied) for dirt, damage or
other conditions which might cause leaks.
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 Lubricate the seal housing running surface on the Air Locker carrier
with oil. Assemble the bearing cup onto the left-hand side of the Air
Locker.
c Assemble one of the two master shims (included with the Air
Locker shim kit) onto the stepped face of the seal housing with the
rounded edge of the shim facing out.
NOTE : No shims other than the single master shim should be
assembled onto the seal housing at this time.
c Carefully install the seal housing (master shim towards the
center) 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.
