chinese lockers

Postby geeves » Sun Nov 03, 2013 12:30 pm

Should be an easy question. I have a chinese rear locker here Ive just had transfered into a 4.3 diff and is going into my bighorn when I have time. I believe it is one of the ones James Whyte bought in a few years ago. The question is What pressure should it run at. Ive got one person telling me its the same as an ARB which operate at 100psi Ive got Brian Howat who is a guru on all things 4wd and diff (and also swaped it over for me) telling me its 80 and that 80 is what ARBs use. He also told me it had been running overpressure and the O rings needed replacing (adds a few cents to his bill). I just set the pressure system up on it on the bench and it switches in just below 30 psi but that is only turning the inner splines by hand.
Is 30 correct or is it only just engaging or is 80 or 100 more correct?

In the literature that I have ARB use 90psi to test with and give a minimum of 85psi and a maximum of 105psi.

i have set up a few chinese lockers and used arb compressors (as i believe there better) and i think they 80 to 100 psi.the seal housing "O" rings don't seem to suffer from to much pressure up to 150psi. in the states they run much higher in there comp rigs
