This page shows how to carry out a replacement of the throttle shaft bush on a Bosch VE pump. This procedure can also be used when replacing the governor cover seal and throttle shaft 'O' ring. There are many more information
sheets available and a list can be found on the DIY Work sheets page.
Before you begin, the fuel pump should be drained of any fuel If you are attempting to carry this repair out in situ, place a plastic bag underneath
the pump to catch fuel as it escapes when lifting off the top cover. Also if the starter or alternator are in close proximity it would be prudent to cover these.
