c
Make sure the seal housing tube and the grooves 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.
NOTE :
Be careful not to bend the seal housing tube or
damage the O-ring grooves.
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
Assemble the shim pack and seal housing (‘
E
’ in Figure 5.) into the
bearing bore of the shallow half of the clamshell.
c
Position the seal housing so that the end of the seal housing tube
goes through the center of the bulkhead port hole
(Refer to Figure 11.).
Figure 11.
c
Using a bearing press or arbor press, press the bearing cup into the
bottom of the bearing bore until it stops against the seal housing.
NOTE :
Do not use excessive force when pressing as this may
damage the seal housing assembly.
NOTE :
You should not be able to rotate the shim pack
underneath the bearing cup if it has been pressed in
far enough.
