Hi Paul

I installed a new water pump pulley today and checked the runout

with a dial

gauge. It was way

out! Futher investigation showed that the pulley locating spigot

on

the shaft

is 17mm and the hole

in the pulley 19mm. Also the bolt holes are 7mm and the bolts

6mm.

My cure, as yet untried, is to decrease the size of the locating

hole to 17mm

by inserting a 2mm

long copper ring 19mm OD 17mm ID. Luckily copper tube comes in

the

exact size.

You have got to be

lucky sometimes.
The picture shows the alluminium disc that holds the vacuum pump

drive pulley.

        Ian,

          I believe your pump is 86-88 (17 mm shaft)(USA) and your

pulley is

  from 89-91 (19mm shaft)(USA). Easy fix is pulley from early pump.

IMHO

Thanks Kelly

Changed the 19mm for a 17mm at the wreckers today. Interesting that the
earlier pulley is also smaller diameter at the belts.

Ian ,
What are the two diameter sizes?
