    Zefal pump disassembly

    Did a search and couldn't come up with anything. I'm looking to paint an old Zefal frame pump hpx and need a little help on disassembly. Any diagrams or instructions out there?

    At the pump handle end, you have a black or silver threaded piece that holds the shaft into the body. Under that, I believe you have a long spring. At the valve stem insertion end: First a large black or silver approx. 1/2 wide medal threaded cap. Under that,if you are set up for presta , there is a black rubber 1/2 " thick spacer, followed by a short spring and washer. Schraeder is the black rubber spacer, a small black cone shaped spacer , than the spring and washer. Not sure if the lever comes out, but if it does there should be a small threaded nut on the end holding it in. Best thing to do, obviously, is to disassemble everything in order , and draw a picture of all as you take it out. I may not be 100% on this, but I hope that this wll help.

    I've figured out the black plastice part on the main body. I was wondering how to get the pump head off the other end of the main body. It looks like a screwdrive would do but it would have to be 14"-16+ long to fit into the body.
