Got the booster plate yesterday. Why do they reccomend drilling the 1/4" hole in the spacer plate where the template shows? If it needed a hole there, why didn't they machine it? Sure there is a good reason, so I thought I would ask. I will drill it today.
That is news to me. I've installed 2 and don't remember the instructions to drill a hole in the plate. I suggest you call TA before drilling anything.
booster plate If it's a booster plate it should look like this: http://www.taperformance.com/basicoil.htm or if the center is open for the gears to ride in then it's a spacer plate. You may want to rethink a spacer plate and just go with a booster plate.
Extra hole I think the extra hole is for another bolt used in early motors or V 6 engines. It should mention it somewhere.
It is for the earlier engines. Apparantely, the paper stating this was left out of the box. I only had the one page with the diagram and template. Once again, thanks guys.
the holes are for a locking pin,to make sure there is no movement because it will rub gear.for safety insurance.bolt just plate on w/feeler gauge in place and drill ur holes and hammer in pins .pull out feeler gauges .then bolt on housing and it will be good.dont forget to put gasket on ,because once u bolt and pin plate its on there good.hope this helps
I guess I was lucky I bought mine locally. It was a sealed power piece for $12 and didn't have to drill a hole. Old style 340 timing cover. Sorry I can't remember the pt. number.
I have installed high volume pumps that required roll pins to be installed into drilled holes to make sure the pump is aligned with the gears, but this one is just a booster plate and the gears don't protrude through it. TA says the hole if for early 60's engines and I don't need it for the 455. Thanks for the help.
