Hi Everybody,

I recently bought a RR and have been enjoying it, and this forum, very much. This forum is a life saver. I hope to learn a lot more, and in time, I can perhaps make my own contributions. I allready managed to repair my compressor, **** that little piston is a pain to get out :shock: . The Arnott gen 2 rear air bags are on their way.

But now, for my first and, fortunately :pray: , a bit silly question:

My compressor is making quite some noise, I suspect that somebody has fitted the rubber mounts upside down, which side has to go up, or down for that matter?
The narrow side or the flat, wider side?

Thanks!!

PS: I was planning to order a britpart service kit, but when I looked at the individual products more carefully, I got the impression that the quality could be questionable. What's the general thought on this?

flat part down, rounded part up BUT I don't think it makes that much difference, more likely a loose nut, or the stud is loose in the housing (epoxy).

couldn't find the britpart kit, link?

Just found a new trick for getting tough pistons off, remove the motor end, and the motor. leave the allen key in the counterweight to prevent it from turning, then turn the motor by hand to spin the shaft inside the piston counterweight. Once the "gunk" is twisted free, it'll come right off.

Hi JJ,

You might do well to have a very close look at the small washers that bear down on the rubber mounts.
They are very slightly dished.
The need to be inserted convex ( dome) towards the rubber, ie, the nut tightens in the hollow.
The idea there is that the washers will tighten against the steel inner sleeve and only bear lightly on the outer rubber rim of the mounting rubber.
If you put them in the wrong way about, you will compress the rubber too much and propagate a lot of vibration through the assembly.

Cheers

Don't do it. They are cheap for a reason. Maybe you'd get away with it with another older Land Rover but it isn't worth it on a p38.

It seems somebody has fitted the mounts up side down :naughty: , thought so. Rubbers look a bit worn, wille replace them, gives me peace of mind. :wink:

I will stay away from the Britpart parts.
