wobbly bottom pully

[andyg plym]

ok cards on the table time, my last 3 cars have been s2's and have all had the same problem which ive never bothered about: the bottom pulley wobbling.
Having suspected the reason for this and having a chat at the last meet ive come to the conclusion that either the crank is feked or i need a new pulley.
any btdt's? must be others as i have had this on 3 s2's now

Is your timming gear cracked by chance? I have never seen this, i think its very scary!

dont think so,car drives fine,no vibrations,idles sweet too.

Its a vibration damper, the pulley is rubber mounted, ok to leave alone if its just wobbling a tiny bit, replace if it wobbles a lot. I actually ran a really wobbly one on the ur for years, the engine was smoother though when it was replaced.

come to mention it the rubber looks a bit perished if i remember right. if i get a new pulley hopefully that may cure it

All ways the way.... Its going to be up setting the crank alittle if its off balance

could be down to the dampening rubber being pulled out of shape by the v belts. if the rubber is getting warm from the engine heat it could get a bit soft. ok when the engine is running but when it is stopped the tention from one of the v belts may pull it to one side and when the rubber cools it may stay in that position. so when you start up again
you have a wobbly pully once wormed up it may come tru again. just a thought

thats a thought mate, my power steering belt runs inside out (it is old and need to replace),ive adjusted it and turned the right way but it always flips itself inside out again.Been like it since i bought it,and ive done silly speeds in it
it runs sweet though!

i had the same problem in the end i replaced it with an alloy one ( after i had bent 10 inlet valves ) no more wobble .
i also replaced the crank sprocket with a steel one .couple of pics

mmm nice,e did you get those and was it expensive?

Andy, I had a wobbly puilley and it was been a broken woodruff key on the sprocket, its really not with taking the chance for a £20 part IMHO.
worth checking.

I agree mate,il get it done along with the cambelt,il get some local s.w.i.l.l.y to do it

I believe i have a brand new 3B pulley for sale if any good

Is that pulley from Mapleracing in Canada?
