I found one ages ago, but can't seem to find it now!

I assume you've seen this page:

I suspect even the 1996 351 used a dizzy. I've been doing much googling and ebaying and can't find a toothy balancer.

Then easy, rebalance an AU one.

Yes - I could not find a 351W balancer with the 36-1 wheel either.

They do have a sensor not sure what it looks at.

They have 8 holes drilled around the edge, guessing the sensor measures this some how.

Thanks SP - good to know for the memory bank - he will need the resolution that a 36-1 provides.

Grant does an engine, balancer to flywheel, for $350 so to sort a balancer would but pretty cheap.

I'll keep that in mind. I'm going to investigate placing my toothed wheel between the balancer and the pulley as that would just require drilling 4 holes in the wheel.

I would prefer to have it behind the balancer for protection but this will do.

My intension is to weld it to the pulley. Use a lath to create a large hold in the toothed plate so it fits against the pulley though still allowing the pulley to sit flush to the harmonic balancer. Once happy weld the plate to the pulley edge. Just need to make sure all is square.

This is the one I bought which is only washer thickness:

Cool - I have not seen that style previously - I am very interested in how it turns out.

I know that many of the pulley have a lip that fits into the harmonic balancer - that style might be a problem - I guess it all depends on what your parts are like. Keep us informed.

OK so the grade 7 geometry was doing my head in so I drew an equilateral triangle in GIMP of the correct size, cut it out, and measured up its placement.

I got to within .2mm





I can't tell if my current pulley has the lip on it to center on the balancer:

Nice work.
Does your pickup have to squeeze between the balancer and the pulley?

[lukep6470]

Yes but The tone ring is a larger diameter than the end of the pulley so there is about an inch of clearance in that gap.

I think it will probably have to be shimmed off the balancer a little which means all the accessories will need to be shimmed forward as well. I think maybe 2-3mm would be enough. It just depends if the teeth are forward enough to give a clean signal.

Of course it could all be wrong and the ring will go in the parts bucket.
