Think this ARB locker is salvageable?

[Mace]

So, this ARB had been sitting in an axle for years now outside. Apparently some water got in the axle housing and rusted a couple parts of the arb. The worst part is on the short axle side where the air collar slips over the end of the locker housing.

I (being the cheap bastard that I am) am considering filling the pits with something then just sanding it smooth. However, that probably won't work. I'm going to give ARB a call to see if they still have spare case parts for these older (RD124) lockers.

I'm open to other ideas as well if anyone has any.

Spray welding then machined?

ARB USA has always been really good to me, I'm sure they will help if the can.

Failing find the replacement part what about turning the whole thing down and sleeving it with a tube?

 

[Mace]

Speedy sleeve has occurred to me. Just making sure it's air tight

 

[Mace]

Jb weld has also occurred to me

ARB may be able to order the part, but it would be shipped from AU on the slow boat (read one to two months lol)

JB weld is sounding better

Loktite makes a product just for that, don't remember the number off hand but it's green and made to seal stuff just like what you want to do.

I'm still thinkin jb weld

How long will last the oil seals with that surface .. ?

 

[Mace]

oil seals should be fine. but i'm honestly not sure. Be a neat test tho..

 

[sadam_husain]

good luck whatever you do mate that surface would need a fair bit of work to get it good enough to hold 105psi of air pressure , have you had a look inside to see if any water got into the spider gears?

I have that part from an old arb that busted a cross shaft and fubared the case but i believe that end piece is good

 

[shawnfj40]

isn't that the side of the carrier? if it is then put a new bearing on and run it. That surface doesn't contact or do anything if I am looking at the hole that the axle passes through. Just clean it up and you should be good to go.

 

[Mace]

Side gears and spiders are good. This is really the only functional damage.

Pees, can you check to set if you still have that end cover? I'd appreciate it if you would!

Shawn, that piece of the carrier is where the air actuator rides. It's pretty important for an arb

JB weld is too soft to give you a wear resistant surface but Devcon and Belzona make epoxies just for this application.

You can get the Quad-rings from McMaster Carr, I can’t remember the third size but I’ll dig up my order if you need it.

This is how I pressure tested mine https://forum.ih8mud.com/threads/target-carrier.796065/page-9

I think it's a goner. The rust looks so deep, that even machined smooth, you'll likely loose the seal against the o-rings. I had one that was roughed up much less than that and leaked like crazy, and was told that particular piece was not available. Some crocus cloth and time and it worked OK(the compressor would cycle a lot), but eventually got replaced with a new ARB.

Similarly, I would not waste time with JB weld. The real effort is setting up the differential and installing. So to do all that work with no real expectation it would work seems like a poor use of time.

The idea of a speedy sleeve and an appropriately placed hole sounds like it would have the best chance of working.

We are all cheap bastards here. Good luck.

Thanks all, I'm hoping that pees has a side plate that's functional still. That would be the best option. I'm not even sure where in Vegas I could get it spray welded..

 

[RAYJON]

some body shops have spray welders now for fixing pinholes in old body panels, its not as expensive as it used to be,

when I worked in the power plant we had some devcon stuff that we used for machined surfaces not cheep but worked and machined like the base metal.. used it on bearing surfaces that were pitted or messed up. i am sure that if polished the o ring would seal...

good luck,

you could always heat it up weld it and machine it back off.. just have to make sure you dont warp it..

if its still sweet inside worst case scenario you'll end up with a stronger 4 spider open diff than a stock 2 spider open diff
