Thread: ARB DIFF LOCK

The diff cover is now black as I think red is too racey for my 101

New wheel cylinders fitted and backing plates painted.

The boots on the tie rod end were replaced with items purchased from the local auto store.
KOK brand..P/N...TE3.......16mmx34mm or KOK brand ..TE4..14mmx34mm.
Both fit

Go on Ron - be a and take the black paint back to red paint.

You have done a great job and also a great job recording your progress.

Cheers

The brake shoes are on with hubs and wheel bearings.
This is as far as I got today.

The air tank is in the front of the fan tunnel and so the best place to place the mini air reg and ARB three way soleniod valve would be on the air tank or on the fan tunnel sides.
The wheel bearings were packed with grease as it will take some time for the oil to get though from the CV.
New lock tabs fitted.

I wrapped the nylon air tube with electrical nylon wrap to protect it.
Only one cable tie is used on the air supply line to the engine oil cooler pipe as the air tank is not very far away.

This is the air tank.
It is of about 12 litre capacity.
The engine oil cooler can be seen in back ground and the nylon wrapped air supply pipe to the diff is coming up over the air tank and though the pic.
This air tank has a metal handle on it as it was originally a 12 volt portable super cheap purchased thing.
It came with air pressure switch , non return valve, safety valve and drain tap etc for a good price and bolted in perfectly.
The guage is easly seen through the front grill and the air out let to pump up tyres can be seen.

this is the same thing but with the air pressure regulator fitted and ARB three way electric valve.
A brass Tee piece was used and the reg was screwed onto that.
The reg has been set to 95 psi
The reg is really not needed at this stage, but later I want to screw the tank pressure to 150 to 100 psi.
It currently runs 100 to 60 psi due to the pressure switch fitted.
With the reg fitted including water trap....... the air supply will be cleaner than any thing that comes out of a ARB electric compressor.
The 12 litre tank with drain tap makes a excellant oil seperator.

In the dark to night I ran a temporary wire from the dash board to the ARB three way valve and took the 101 for a quick play.
I have driven front diff locked stuff before in the form of a Haflinger and Aust army Unimogs.
This was different .
The haflinger is very light with the weight over the rear axle and therefore the front locker has little effects other than extra traction.
The mog is a lot heavier with power steering and hub reduction axles(portal) and is a totally different thing again to the 101.
My main problem is find a place close to home in the dark that would challenge the 101 with a Detroit locker in the rear which cannot be switched off.
I didn't find anywhere ,or will I in a hurry.
So I found a gravel road and twisted the wires together and on the locker went.
The heavy steering and a locked front diff means you pretty much travel in a straight line on a hardish surface........in fact one front tyre is slightly worn more than the other caused the 101 to want to vear to one side with little chance of correction without straining the front axle and CVs.
I have to reverse back to release the locker at times.
The engine being towards the front of the 101 adds to the effect.
I need to spend much time with this locker in really hard going to see the benifits of it as the detroit in the ear and the constant 4wd is doing every thing you really want to do 95 percent of the time off road.
the story continues.
