Don't forget to have a look at the reed valves whilst you have it in bits.

Yea just done them now, so all should be sweet if I ever need that block, may get some O rings and do the out one up, then I have a working spare same with the compressor,

Nice one glad you got sorted.

Hold yer horse meat this burger ant cooked yet!!!

A m8 of mine is going to do a few collars (one that fixes on to the Teflon seal) for me.... anyone think its a good idea to make the cylinders as well?? (the one the piston goes in to) I have a aluminium one and a brass one (the ring thats goes on the Teflon seal) people dont seem to have them, and you have to be quite brutal getting them off the Teflon seal

The way I removed the ring from the piston was to heat it up with a small butane soldering torch and what was left of the teflon seal expanded and pushed the ring off

Would not bother trying to get a cylinder made, just buy a OEM one. The material grade, hardness and finish have got to be right. Seal retaining ring comes off easy using edge of a white handled kitchen knife, tapped with a pin hammer, done mine every year and its still fine.

Once you've done on piston seal and can see how it works it's hardly difficult. I start with a Stanley or single sided razor blade, prise it gently until I can get a wee blunt screwdriver in the gap then put a chamois in the vice, grip the top and pull. A quick wipe round with some fine emery cloth to remove any burrs and re-build.
As for the sleeve, when you can buy it as part of the kit, for so little, it's hardly worth trying to re-invent the wheel.

No need for brutality. Just follow the instructions in my "How to" that's what it's there for, to help people. If they don't read it they won't know what to do, will they? The cylinders are hard Anodised for wear purposes bare alloy is no good. If you change the seal ALWAYS change the cylinder.

Still got problems...

Put the new Teflon seal in the compressor pump, can still stick my finger over it, air is coming out, but its meant to blow so hard that you cant put your finger over it right? air is not coming out of the exhaust valve on the block..... what next please???

Your have to recheck the seal in compressor what condition was the barrel in ? When its running does it sound good or slurred/ slow

If you remember i advised you to look at the reed valves when you had the compressor stripped down. You said you had obviously you had not. Set them up as described in my "How To". Put your finger over outlet air should be forced past your finger.

Also check air intake filter isn't blocked

The piston barrel is perfect, no wear or marks of any kind in it
I will check the Teflon seal again... sounds like its running fine to me
Air intake filter is new, got it with the Teflon ring

Is this the reeds your taking about in the how to? and is the O ring on both sides?

Ok changed the O ring on the reed, something working anyway, n/s front and back goes up all the way, o/s f/b/ on stops still, strange noise when I turn the engine off though, a big pishhh (air) sound from the engine bay??? so thats got to be a part of the problem maybe why the offside isn't going up?? will wait for the wife to come back soon and she can turn the engine on and off while I fine out where its coming from in the engine bay

Most likely the exhaust valve opening and closing...mine used to do that when the compressor turns off!

Sorry forgot to put the exhaust back, I think that was the Pishhh sound

Saint your correct m8

Well the ESA fault isn't coming up, but I cant drive around like im tuning right all the time lol

O ring i am on about is under exhaust reed in bottom picture. You may have got a new one with the seal kit. Make sure the reed sits flush on top of it. O ring needs to be stuck in place with a little silicone adhesive. Wipe excess off it. On the type of compressor you have there i have seen where O ring has fallen out because it was not sealed all the way round when assembled and the backing plate is set to far away from reed. Check it for damage. If that is not sealing correctly the compressor will never build pressure.
