Camaro --

There are three different flywheel "tooth counts"... and some starters might only mesh with one or the other.

One is 142 teeth, one is 158 teeth - the other is 163

Divide your flywheel/flexplate by quarters and count the teeth and multiply by 4 - to be certain what you have.

RE: The 'grinding' you mention. Is this only when trying to crank the beast over? Does it stop when you disengage the key?

Do you know how to set your static (initial) timing before starting the engine?? If not I can tell you how to get it VERY close for startup...

You need to re read my post. There are "TWO" measurments to make a starter work correctly.

1. The distance between the end of the sterter pinion and flywheel teeth. (What is pictured in my thread previous) Must be over .100 but not greater than .150 from memory.

2. The distance between the tip of the starter tooth and the gut of the flywheel. (how many different size paperclips are there?) I have about 6 in my office. Probably not the best way to check it. Go to sears and get you a set of pin gauges. .035-.060 sounds close.

In picture number two in my previous post, you see a shim sitting on top of the starter housing. This is moving the pinion gear farther away from the flywheel teeth. If it is to close, you starter will not engage properly and will stick in the flywheel teeth. By the way, it's either a 153 or 168 tooth flywheel. If the gears mesh, they mesh.

You're right on the money. I spoke before I really looked. My apologies!

I'm not following your "tooth counts" are we not talking chevy's here?

There's 153 and 168, both of which are irrelevant to starter gears.

Yeah Mark -- we ARE talking Chevys...

There are also 142 tooth CHEVROLET flywheels and 139 tooth flexplates....

Which is why I said maybe he should count them - because who knows?? Maybe he's got a 142 and the gears don't mesh... since we're not there to see for ourselves - might as well cover all the bases!

Here -- go buy a 139 tooth flexplate...

There are also MANY 142 tooth flexplates AND flywheels for MANY chevrolet engines small and big block.

Since we have no idea of the SOURCE for his parts - might just double check!

As long as you're ordering that 139 Tooth flexplate... might as well get one of these chevy small or big block 142 starter motors to go with it.

okay, i am going to try the new starter, which has the removable mounting block.

I have: Removed the nose piece, installed a a shim in the mounting block, alighted gasket and housing, and put shim in position, installed back the 3 bolts, made sure armature is sitting flush with mounting block.

i will be making sure that my ring gear clearance (pinion not engaged, measuring to .100 inch)

also, making sure the backlash of the pinion and the flywheel mesh is .15 inch


The thing i am worried with this starter is, the pinion gear is already meshing with the flywheel, and the clearance i would need would require a large shim to move the whole starter back, while leaving the mounting block still bolted to the engine, this would ultimately move my pinion back, and i would be able to to have a clearance or .100

AH so hard to explain, which we could have a video chat with like 10 of us and me explaining lol!

I ll take pictures!


also,

vegas69 right on the money, you were right, look below

Speedtechs number is (local to you) 604-460-0204. Call them if this does not work out for some reason. It looks like you have all the information there now so I hope it all works out. Let us know!
