Petergg Posted May 10, 2007 Share Posted May 10, 2007 Hi, My front ARB was leaking very bad air was coming out of breather at a high rate, so took it out and thought I would connect the air line back on to it and see if I could see where the leak was. But it did not leak once out of axle, any idea's please? Peter Quote Link to comment Share on other sites More sharing options...

Peter It appears that the problem was with the bulkhead fitting and when you reconnected the fitting with the diff removed you somehow fixed the leak. Or the ''o'' rings on the rotary air connection are worn and leaking when the carrier is turned to a particular position. Try rotating the crownwheel a bit at a time with the air connected to check if the leak starts again. If the carrier bearings are slack, allowing the carrier to move side to side a little this will also cause the o rings to leak.There was a thread on the Pirate forum where some members living in the colder snowbelt regions were experiencing ''O'' ring leaks due to shrinkage. If the diffs were operated long enough to warm up a little the leaks would stop. Bill. Quote Link to comment Share on other sites More sharing options...

Bill. Thanks BVS, it had new seals etc. only a few weeks ago, so will check it out more inc bulk head fitting and refit with fingers crossed.

Petergg Posted May 11, 2007 Author Share Posted May 11, 2007 Tried it again, and is leaking around the back of bit with pipe fitted to it. I should stick to Jac mac's. Peter Quote Link to comment Share on other sites More sharing options...

I have 5 year old Jacmac Hilux difflocks that I remachined to fit Rover diffs. and the locking side gear together with locking dog ring have been on the obsolete no longer available list for 4 years.
