Thread: Salisbury diff housing failures

Yes I have thought about machining down some schedule160 73mm tube to fit, but I have to purchase a whole length of it (6m) but I only need 1.2m. Long side tube is approx 750mm, short side 400mm approx. I would have to machine it to just under 68mm. The hollow bore I can get at the right length is 66.4mm od. So .8mm tolerance either side.

1.6 mm is a fair bit.

I am sure others would be interested if you sold pre-machined sections the right length (e.g. me).

Having a close fit would reduce the stresses on the outer tube. Adding a few plug welds between the two tubes along the length would help too, but you run extra risk of distortion and leaks.

OK, well will wait for a price on a length of pipe and go that way. I can get enough for 5 diffs out of a length, and ballpark price I got today for a length was $350. So $70 a diff plus machining. If I can find someone willing to do that at the right price then its looking feasible financially.

I'd be interested in a set too Damo.

OK, well I will get a length in and try find someone who can machine it up for next to nothing.
All I need is an exact internal measurement of an axle tube. For me to do that means stripping my diff, which I will do IF I have to.

I have a standard 110 housing in the shed, I will measure it tomorrow.

Champion Brian. If you can get me all diameters and lengths each tube should be cut to that would be fantastic

No worries, in fact I would be interested in 2 sets as I will probably will upgrade the one in the V8 County that I am going to refurbish into a 4BD1 County shortly.
