Alternative Crank Pulleys.
Turbo Mini Forums

I need a crank pulley for a grooved belt complete with damper.

Ideally, I don't want to fabricate one. Anyone got any ideas?

I'm aware that people sell kits but I don't want to blow ?196 on something I can make myself. After all, I expect Minispares are just using one of a Nissan Micra or something.......

There must be a way. Apart from cutting and welding existing pulleys. Last time I tried welding something to cast iron, it fell to bits, I think the stock pulleys are cast.

I'm spending far too much money on this as is......Help!!!!!

Bugger off, I'm getting there.

If you don't want to buy one, make one, or modify a stock one... I'd favour the first option! Single Vee's seem top work for most. Why do you have a dislike?

or, is it for your SC drive? If so, then making one is even better, as you can make it bigger than the MS one so you aren't limited by the size of the sc pulley so much...

I figure it this way, blower has grooved drive, alternator (RX7) ditto, water pump pulley is easy to make. Leaves me with the crank pulley. Got to have the damper, which might make it interesting on the lathe. Would have to turn a whole load off and then have to fit a fabricated outer to that. (as it isn't big enough to start with). So, I suppose, since my vibrations will have been shifted around a bit, and the rubber is no longer its correct hardness, I could attempt to........no, it's too difficult.

Worst comes to the worst, I will have to fork out, allthough this is allready getting more expensive by the second. Ouch.

The SC draws about 25 Hp according to the graph which I have. (Must be wrong). The damper is necessary.

If it does look like a tall order, I will consider different ways of skinning the cat.

What size o/d are you looking at,and its a flat 6 belt ennit

doesnt the "S" pulley have a bolt on damper? therefore you could make a pulley to suit that?

I was thinking the same - no rubber damper on the 's' engine i recall....

glad to see i remember something right

ive got a set of toothed belt drive pulleys that use a front pulley with no damper but then you can just bolt the "S" one on.

Yes the "S" damper and pulley come as two seperate parts.
