Lady gets ARB Air Lockers

 

After the hole was drilled, Donnie counter drilled (chamfered) the hole that he just made.  This helps relieve any pressure around the bearing seal tube hole and also makes sure there are no sharp edges or burs on the bearing cap.

 

The bearing cap with its new hole is slipped over the metal tube and the bearing caps torqued to spec.  Again, Donnie checked the backlash to ensure all went together as expected.  So far so good.  He is making good progress and is way ahead of the schedule I was hoping to be on.  

 

I thought I would toss in a close up picture of the differential housing penetration (as ARB calls it).  Donnie will route the metal tube up through the bottom of this fitting and secure it into position.

With the metal tubing properly clearanced (so it does not touch any of the rotating differential) inside of the housing, the nylon tubing is connected to the housing.  Before the diff cover was put into place (and before the RTV sealant was applied), Donnie verified that the cover was not contacting the tubing.  If it did, one would not know how or where the metal tube might be moved to when the cover was bolted down tight.  This could cause a hole to be rubbed in the metal tube.  

 

Before sealing up the housing, we leak tested the differential.  This was the done the same way I did the compressor leak test, except that we were testing the nylon tubing and Donnie's differential handiwork this time.  After all was considered acceptable, a bead of RTV was applied to the sealing surface and the cover was snugged down.  The rear locker was blessed off as done.
