Thread: ARB DIFF LOCK

The locker is refitted with both caps and further checks done and to see if the hole in the cap was drilled in the right spot.


The O rings have not been fitted .
the caps are lightly torqued and bashlash rechecked with dial guage and the preload checked by trying to lever the locker side to side with a bar and re checking with feeler guages etc.

Final checks with 5 thou centre bearing preload .

The locker is removed and the O rings carefully fitted and lubed.
The O rings are really Viton quad rings.

The locker is finally place back in and the housing spreader is released for the last time.
the bearing caps are torque to 100 ft lbs.
the crown wheel is bearing blued to check if the mesh is the same as it was as it came out in the first place.
Everything is checked again.

The copper air supply pipe is bent by hand to clear everything and to avoid any movement by oil washing against it or it rubbing slightly against the diff cover plate.

A mini pipe cutter is used to cut the excess pipe to avoid any filings falling inside the pipe.

The air supply fittings are screwed in the the diff housing and air line fitted.
the heavy duty diff cover is fitted.

New axle tube oil seals fitted and the drive axles with CVs fitted.
The axles were a neat knock in fit in to the conversion side gears inside the locker.

I cleaned up the pitted CV joint balls abit with this.

Cv housings refitted as per the 101 workshop book and this is the current state of affairs

The locker was checked for operation by using a air nozzle to pressurise the locker hose and then turn the axles by hand.
It works !
