Technically .325 is deep enough pin is .312 dia. it was deeper than the dia.
The dowel pin does'nt keep gear from moving. The bolt/washer clamp the gear and cam together if dowel breaks something else is wrong,the dowel is only to line gear and cam up not to keep from rotating .Cloyes told me that and I did'nt think that was right,so I checked w/Tim @ bullet/ultradyne and he said that was right.
So then I started to think about it alot of 4.6 dohc fords don't have anything in keyways of gears that run between cams,LS1, LT-1 and lot of other engines don't have keyways&keys for the balancers(dampners)so then it started to seem more correct,then I got to thinking how does dbl. key crank on blown engine work?
You know the tiny woodruff key could'nt keep the spider from turning on the cam adapter on Jesel belt but the clamping pressure/taper keeps them from rotating

Don't try to drill broken pin completely out, drill and tap hole in the pin then use a bolt& nut w/ a spacer that your pin will fit inside of,and tighten nut against spacer to pull broken pin out. You can also do this on broken pressed in rocker stud,etc.

To make long story short make sure your dowel is'nt holding anything from sitting flat,that washer,bolt etc are all stong enough and torqued enough.

Thanks Tony, I think I've got it now. Not sure why the balancer/pointer where off 8degs (balancer problem?) but I redrilled the mounting holes for the pointer and its good now. How's your dad doing? Robbie

I suspect the balancer is off. We have used a timing tape to fix that on ocassion. They are not expensive an we keep em on the shelf. Sometimes balanacers are mis marked, and others the pointer is tweaked.

Dad is doing pretty decent all things considered. Now its all about the therapy.

If it is a stock Ford unit it very common for the outer ring to slip, there is a very good company called Damper Dudes in Calif that rebuilds stock units.
