Took the pump out of 04 XJ project. Lots of surface corrosion, frozen cylinder bolt, water inside air dryer, retaining spring dissolving. Cylinder has a very slight Ridge, hand reamed to break glazing to little effect. Motor, crank, seal all looked good. I think the desiccant was causing a lack of air. Ordered off eBay a used pump from California. Arrived today, it looks great, no corrosion, disassembly markings visible many places, I'm wondering even if I should open it up. My opinion is that pump is a good design that should have been made more accessible, particularly the desiccant. The motor/crank seems quite strong. The cylinder and all wearable parts should be made available. Are they?

 

Have a look at http://bagpipingandy.com/

 

I'd rebuild the used one with one of bag piping Andy's kits anyway.

 

Is Andy kit better than PTFE KIT I just bought?

 

Also, going to use "gray" with O ring /cylinder as white stuff got past ring.

 

No idea. I've only used Andy's kit with success in the past.
