hi everyone
I've not been on for a while as she has been running well but today gone down to bump stops got her home already had new stuff for compressor. (cylinder and seals), so all fitted but she still wont rise.
my question is how much pressure should come out of compressor. If I remove pipe I can put my finger over connection when its running but it does blow my finger off fitting.
when I reconnect the pipe and take of the pipe to the air dryer there is very little air coming out (I can put my finger over it no problem and hold it there and no pressure build up ).
is it the compressor or is it the valve block. I have put valves on lines to air bags and pumped up, it has lifted and stayed up so no problem with bags or lines to them.
hope someone can help
cheers tiv68

Could be a split diaphragm valve in the block. Unscrew the silencer and see if air is coming out there.

On the upside, the valve block isn't hard to refurb and the kit is cheap... if you haven't done it, you probably should.

Maximum in cylinder pressure is probably north of 170 psi with new seal and cylinder. Cut-out range is 138 - 152 psi.

Not gonna hold that back with your pinky!

If you've re-built the compressor so piston ring and cylinder are good check that the inlet valve is correctly installed and working properly. Its been known for folk to put the backing reed in wrong way round on this style of valve so pretty much no air gets in. Ooops! Not me but I know a mad who knew lots better and still did. Some good info here :- https://www.landyzone.co.uk/land-rover/checking-eas-compressor-and-diaphragm-valve.172555/ . Particularly the bit about valve O ring cross-section. Something you'd not normally think to check.

Remember it’s going to take upto 10 minutes to repressurise the tank, some times if they don’t lift, stick a jack under the tow bar and give it a hand,, the height sensors sometimes don’t like reading when down on the bumps
I had a dse that if it went down, I had to bounce on the tow bar, then it would lift

hi
thanks everyone for your reply's.
I have taken off the valve block and I am glad to say that I found the diaphragm and it was split.
new one ordered with full set of O-ring seals so total rebuild then hopefully it will all work fine again.
many thanks
cheers Steve

hi
just to let you all know all O-rings and diaphragm replaced and she now goes up and down as she should.
totally empty system to full height 2 minutes never been so quick.
