crank triggering
Turbo Mini Forums

Hello folks,

I'm looking at how to fit a trigger disc on to the crank at the moment, the problem is I'm using an S crank damper and a belt drive, which screws things up a bit.

So I'm thinking that my best solution is to get the damper ring machined with cut outs, Can anyone do this for me? for a fee of course.

could always give AlexF a shout, i believe he does the normal ones with the teeth machined into them.

s crank makes it easier as it has some nice bolt holes to help you mount it

well, the problem is, due to the belt drive, there's no room behind the pulley for the trig wheel unless I space the pulley and damper out about 1/4" even then I'll have to machine the disc face to fit proper.

I could sandwich it between the pulley and damper but then the damper could end up on the piss as it is no longer located on its sticky out rimmey thing.

What does an S damper look like?

Minispeed do something too but I don't know a link.

nope they only fit the non S damper, the minispeed one is the same as the KAD one too.

Could it be modified to fit though?

Why dosen't it fit? is the mounting to shallow or to deep?

the dish in the S damper is about half as deep and a larger diameter, plus there is 4 polts sticking up where the damper and pully attach.

This is a cooper damper machined for 36-1.

Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe.

I'd say the 4 bolts make it much easier to go about mounting something than the normal pulley. If you can get hold of a blank undrilled trigger wheel, it would just be a case of drilling 4 holes on a PCD to match the damper bolts, then make 4 spacers sufficiently long to space the trigger wheel so it sits _just_ off the damper. Then bolt the lot up through your spacers and hey presto.......

Why not get a blank trigger disc and get it machined to fit the pully and weld it on the outside I did that with mine it was a dodle.
Why do you need to put it on the inside ?

just out of interest, has anyone concidered using a fluidic damper rather than using the old rubber ones or a cooper s one? Surely the've gotta be better, dunno if its worth the cost though? Was thinking about making up my own hub for it integrating a trigger wheel.

I've seen the future and tbh its Pie

Cheers for the input guys, I've got acces to a mill now so i'll macine them directly into the damper.

According to Keith Calver he's had issues with the available fluid one that minispares sells and recomends the S one over anything else available.
