36-1 toothed Pulley
Hi,
Is there any way of getting a pulley with a 36-1 toothed wheel built in that will fit a Pinto.
Got a standard wheel mounted to my pulley but just wondered if you could get one built in.
Cheers
Scott

is the edge of the pulley fairly meaty?
i've seen a photo somewhere of a pulley which had holes drilled into the side of it instead of the usual arrangement. can't find a photo
of it now though...

There was an article in PPC the other week where they drilled 36:1 holes in a crossflow flywheel to replicate the set up on a Zetec.
Can't see why that couldn't be done on a Pinto

I thought about having a crank pully for a car with power steering machined but it weighs a ton so went for the trigger wheel option and will tack it
on

It was Dave Walker that did that IIRC. It was done on a milling machine to get the accuracy required.
Need to be careful regarding the balance of such a thing.

but do you really? a normal trigger wheel is never going to be in balance as its got a tooth missing. i don't think it'll be too bad
unless you drill the holes on one side twice as deep as the opposite side

Not sure it was Dave Walker who modified the flywheel in the PPC article? I would have thought that as the engine in question was being rebuilt and
modified it would have had a full engine balance carried out. I would be more worried about the fact that the flywheel is cast with 36 possible stress
points put in.

Actually they drilled all the way through the original cut outs in a Zetec flywheel and then used it as a drilling guide for the crossflow flywheel.
No rotary table or milling machine etc. was used IIRC.

You certainly do. PPC had theirs properly balanced along with the crank.
