To view links or images in this forum your post count must be 1 or greater. You currently have 0 posts. may be just cant remember if the petrol rots rubber but something like should have the size you need

so long as the centre is a tight fit around the pin thing it should be fine may be i think????

Well measure the thickness of your plunger then!
Is it a Vernier guage I think you use for that?

its a tapered plunger diablo,i cant find my vernears or mic atm
ive made a plug guage by using 2mm drill bit,2.5mm drill bit,and a 3mm drill bit
to see if i can judge the size of the hole



feck it il call into a plumbers shop termoz and get a 3/8'' washer they should be cheep enuf

A leather washer should do it surely, because it should grip the shaft while still being expandable?
