3 Installing the Air Locker

3.6 Drilling & Tapping the Bulkhead Port

A port must be drilled and tapped through the differential housing to

allow the seal housing tube through the housing to connect with the

air line from the air compressor.

c Remove the Air Locker from the housing.

c Mark a spot on the top of the outside shell of the differential

housing in the position shown in Figure 8. The location should be

about 45mm [1.75”] from the gasket face of the cover flange and

very close to the teeth of the ring gear inside.

Figure 8.

c Cover the drive pinion and bearing seat areas with rags to protect

them from metal filings.

c Drill through the housing square to the outside surface using a

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

into the housing.

c Carefully remove the rags and inspect with a service light inside the

housing to insure no metal filings are left behind.
