mw pump on m

I.H.parkingonly · Jul 29, 2008

The m&w pump on my m started leaking sunday, Looks like right between pump and distributer. I havent had time to take it apart yet, does anyone have an idea what the problem may be? I am hoping just a bad o ring. Can a guy still buy rebuild kits for these pumps?

Probably just a seal/"O"ring at that end. There are no kits I am aware of, but someone may supply a positive answer. The seals and/or rings will be garden variety Chicago Rawhide, or National component. If the pump is still making good pressure, The seal is going to fix it.
If there is a groove worn in the shaft, it will be necessary to use a speedy sleeve. The "O"ring bore may need to be enlarged to accomodate the sleeve. The use of Teflon based "O"rings is also a good idea if available. Take pictures of things while disassembling. Be clean, place parts in order on a (used) lint free towel. JimN
