Locker Plumbing

[wayneg]

I will be fitting my locker into the rear of my new car soon. The last time I used a separate ARB locker compressor fitted under the bonnet. As the new car has LPG, space is even more restricted so will use the EAS supply. I plan to tee into the hose at the valve block outlet 6 and I already have a nice little solenoid valve to fit.
My concern is the pressure will be too much so need to reduce it. Has anyone done this and with what. I am thinking one of these valves, what do you think, will this just reduce flow not pressure?

I tapped into the air tank and ran a line to the rear drivers 1/4, put the solenoid in there, then ran the line to the locker from there.

Bugger all air line required and as I've used a ball valve at the tank, I can isolate the air supply to the locker when it is not required. I am running full tank pressure into my locker (Ashcroft) with no ill effects after nearly 4 years and heaps of use.

I think the pressure will stay the same, just the flow will be slowed with that valve...

Keith has run the Ashcroft locker with no regulator for a while. And has his solenoid in behind the rear right tail light I think (but could be slightly off target).

I run the Ashcroft as well, but I used a standard air regulator turned down to 90psi (6.2 bar). My regulator is mounted in the engine bay and comes from pipe 6. I run the pipe down the passenger side. Off memory it goes gown behind the front wheel lining, along near the outside top of the chassis (cable tied at various locations) and then runs near the exhaust at the rear but far enough to not get hot. Left just enough slack so it doesn't get pulled on at full droop. Tried to have it come down at an angle off memory so the hose length didn't change so much,,, But can get under and look exactly how I did it near the rear axle if you want.

Edit: Just saw Keiths post....so there you go.

[Pete38]

Another thing to add. If you are going the Ashcroft option, then there is loads of air pipe supplied so your options are open regards that aspect.

My locker is a ARB air. It was in my other car with the compressor in the engine bay. What is a Std pressure reducer? I have one of these ( in photo) that I could easily fit, I want a pressure reducer, as I have had issues with this locker in the past.
Dont need help fitting or running lines, done it many times before. Today reset the diff tolerances so ready to drop in.

Yep thats similar to my pressure regulator. But I don't have the oiler part (I think thats the extra part). You also don't really need the moisture trap but it's hard to find one easily without it. Well I gave up pretty quick.

[Keithy P38]

Looks like the go - wind it down to your desired pressure and job done.

Found one, $5.00, on its way, I have 1/4 NPT 6mm fittings to suit.

HI

The extra gubbins on these are airline filters, designed to remove oil and water when spray painting.

They usually come off for cleaning but given the type of compressor and the air drier fitted to the P38 i would say they are superfluous.

Actually looking more closely one of those may be an oiler which adds oil to the airline when used with air tools, that would probably not be a good idea to have in the system!

Oh yeah and they are usually called regulators ;)

The unit with the separator and oiler attached was bought to fit to my other car. Crossing the Nullarbor last year the locker decided to push all the diff oil back up the airline and out through the compressor solenoid all over the engine bay. I thought fitting that would show and trap any oil coming back. I traced the fault to a worn sacrificial bush in the locker causing a minute wobble turning the locker into a pump, multiply by 3000klm and it emptied the diff . Seems like a not uncommon problem with ARB lockers.

I can't see the lettering well enough but the one one the left seems to refer to max water drain level so it is a water dryer, the one one right seems to refer to max oil level so I suspect it's a line oiler, not a filter.

You need some kind of trap to stop the oil coming back up for sure.

I guess the water/oil filter should work in either direction

Hopefully the issue is fixed, I had a new bush machined up and I fitted all new seals to the locker when rebuilding the diff yesterday. If oil does get pushed up again it will come out of the solenoid vent before getting into the EAS supply. I will fit the pressure regulator in my last pic, $5 on ebay, not the one with the oiler and water separator that I already had

[benji]

I did a similar thing too. I plumbed into the eas just behind the the air tank.
I've set the regulator to 90 psi.

OK. The large unit, The left side is the regulator/dryer. Air passes through the reg and drops pressure and then into the dryer. The pressure drop aids condensation of any moisture. The right is an oiler, not good for spraying, good for tooling.

[Pete38]

Never seen any water in the drier on mine. Guess the locker doesn't have much flow/volume of air for the drier to catch much and yeh the pressure drop helps in reducing condensation anyway.

Hi

Since the P38 already has a drier in the system you are not likely to see much water in the additional drier
