[Vwdiesel] injection pump info 1982 and 1980 NA.

[Gary, Orlando]

Hagar,
With the belt wanting to ride off the pulley is most likely worn pump
shaft bushings. Yes, these are bushings and the are two. This is why
belt tension is critical. Too tight and you have premature bushing wear.

I've had two pumps apart, and I have yet to see a worn plunger assy.
There are no radial forces exerted on the plunger during operation. Both
of the plunger assy's still had honing marks on them and held pressure
when worked by hand. No tell tale 'mirror' surfaces amidst the hone
marks.
