c Cover the bearing seat area with a rag to protect the inside of the
clamshell from metal filings.
c Drill through the housing square to the outside surface using an
11.2mm [7/16”] drill.
c Tap the hole from the outside using a ¼” NPT pipe tap.
c Remove any sharp edges from the hole that may chip-off and fall.
Carefully remove the rag and inspect with a service light inside the
clamshell to insure no metal filings are left behind.
3.8 Installing the Seal Housing
c Sit the seal housing on top of the shallow clamshell half.
c Without using sharp, jagged tools such as pliers (usually your
hands are the best tool for this job), gently bend the seal housing
tube so that it lines up with the bulk head fitting hole as shown in
Figure 10.
c Mark the tube approximately 8mm [5/16”] out from the end of the
hole, and cut with an automotive brake line tubing cutter.
