It looks a bit white in the picture, could just be the light but if there is a white film on the surfaces, it's the dryer desiccant breaking up.:)

Think Keith may have said a white deposit on the diaphragm seat. Which i also noted but could be a trick of the light. The flakes are not dessicant they are debris from the thread lock. As i said before a view of the diaphragm itself would give a better idea.

Don't forget the three bits at 10.00o clock and the bit at 6 on the outer ring .

I wasn't gonna point it all out - just indicators thereof and as such the viewer can then determine the rest!!

Oh the piece in the first Pic....looks like it comes from or was on the block at around the 9-10 o clock postion from the witness mark

The diaphragm valve seat is the thin circle of brass in the middle. There is a slight hint of white from twenty five to to around ten to. That could be powdered dessicant deposit or a trick of the light. Nothing else visible indicates dessicant.
 
I don't really want ot get involved in this pointless argument, but on mine the dessicant had put a hard film of white over everything and looked much like the photo, in addition there were small pieces of dessicant floating about. There is no way that the pink thread lock residue can get into the works other than at the point of disassembly.
ANY contamination in the valve block will cause problems, it needs to be cleaner than an NHS operating theatre.

The one shown is cleaner than a national health operating theatre. :D:D:D Don't think the camera flash gives a true perspective Keith. The lad does not report any white deposit on the solenoid valve seals.

Sorry to have left you guys to get on with this interesting exchange but I've been busy for the last few days : spare has not yet arrived in the mail.
Are there any other pics you would like me to take which might assist ?

No apart from me getting mixed up with two different threads. Would be maybe a good move to strip block and see if there is anymore FOD in there or any dessicant contamination on the valves. White crust everywhere. If so clean of and change drier and then stick new diaphragm in.

The white crusting emerged from the studs :it moved around when I was fiddling around with it.
Thanks for your interest & your input.
I'll report back when I get it back together.

New daiphragm arrived today : fitted ( did not strip the rest of the block) :left door open about 7 mins and mighty cheer as suspension went up !!
Thanks a million again.
A couple of spin offs :(i) the new diaphragm was completely different from the one which came out so much so that I phoned Simon at Symtec (?) who said that what I described as the old one sounded like a Dutch after market job ( it had no metal plate in the centre and was really tight in the seat.) (ii) I managed to strip the threads on the exhaust filter ! Got it stuck in off the threads and exhaust puff blew it out !
New filter on order : any probs running without it other than dangers of crud.?
Just a cautionary tale for members : I had spent yonks on trying to race what I assumed must be a leak at the bags after I had replaced rear bags. Problem was down to the diaphragm all the time . Frankly hardest pasrt of the job ( for me) was getting the leccy plugs separated !

Dutch diaphragm is solid rubber and a lot stiffer than OEM one. Does not give the same whoosh of air as gallery is evacuated when compressor stops. No problems running without exhaust filter its just a silencer.

That's what I took out : some sign of uneven wear at one side which might be attributable to the piece of crud I founf in there.

Could the piece of crud be a bit of old piston seal from a previous compressor that failed ?
Just a thought.

The piston seal is teflon & brittlish.....the crud was definitely like a piece of string. I examined it and the old diaphragm to see if it could possibly be a shredded edge: definitely not.
The system is operating differently from what it has done for years.
