1928/29 EW oil pump
« on: 04 Jul 2015 at 14:48 »
My bike has the oil pump mounted on the tank. I am told that the pump needs three leather washers, but as mine had disintegrated, I am scratching my head as to where they go in relation to the drum-shaped 'piston' which threads onto the plunger shaft. Also, that piston has different diameters at the ends -which way faces downwards? Thanks

This post will give you the arrangement of the leather cup washers.

The washers themselves are available to club members via the London Douglas Motor Cycle Club, or you can sometimes source them on the internet from outfits that supply old farm type water pumps. Though most of the latter only stock the larger sizes these days (1.5 inch and up).
