Help! I just installed a new Luk clutch in my 62. While I was at it,I had the new pressure plate and my original flywheel balanced. I bought a new flywheel ring gear at the local parts store and had my machinist install it while he was balancing it.. (The original flywheel ring gear had a little wear so I thought a new one was in order). Before he installed it, I placed it on top of the original and they 'seemed' to match up perfectly. Well. everything is back together now and the starter gear will not mesh with the new 168 tooth ring gear.Lot of grinding noise when trying to start !!! (Everything under this car is the original stuff, i.e., bellhousing , starter, flywheel, etc). The starter gear is hanging up in the flywheel teeth. When the starter gear gets into the flywheel teeth, it will not pull out all the way without binding. The ring gear teeth are 'very slightly' angled.If I take it off and turn it around, it will still be angled the same way. My question is this. Are the ring gear teeth supposed to be straight across with no 'front or rear'orientation? I have been fighting this for several days nows. I have ordered another ring gear from Paragon to see if it's any different. I have even tried 3 different starter gears but the same problem exists. Thanks so much, Steve Wittler, Chattanooga.

try shimming the starter away from the block
the new starter ring MAY be larger than the original one and the starter pinion is bottoming out. starter shims can be picked up at the local auto parts. -
Re: try shimming the starter away from the block
I'm assuming that if you have all original 62 parts, that you have a starter that bolts to the bellhousing rather than the block. That creates problems for shimming away from the block, because there really is no adjustment on one of those starters/bell housing combination. I know this doesn't provide a solution for you, but helps contextualize the dilemma.Comment

You can cock shim the starter to the bellhousing. Same thingComment

Re: try shimming the starter away from the block
Hello Mike. Thanks for responding. Yes I do have the original type starter that bolts to the aluminum bell housing. I am beginning to think that the new flywheel ring gear is just a poor piece. I have spent hours with a file trying to de-burr it but the starter teeth still gets hung-up in the flywheel teeth. I talked with a 'Tech'at Paragon this morning while he was holding one of their ring gears in his hand. He said that the teeth were smooth and clean on both sides. Since the starter doesn't shim and the bellhousing has no 'play' in any direction...the flywheel ring gear has to be the only culprit. I have been trying to find out if the ring gear has a front and back. I don't believe it does. Even thought the teeth are slightly angled...turning it around would not help. I am assuming that the teeth are angled slightly to assist in kicking the starter gear out once the car cranks. Is this correct? Thanks, Steve.Comment

Steve, To my knowledge the teeth should be...
absolutely straight across. There is no front or back. As a matter of course, an old ring gear can be removed, flipped and reinstalled to gain a "newer" set of teeth that the starter first engages.Comment

agree 100% with dennis. never seen c-1 ring gears with bevel. pull flywheel and replace the beveled gear with straight tooth critter. mikeComment

Re: Steve, To my knowledge the teeth should be...
Mike...when I say that the flywheel teeth are angled, it is so slight that it is barely detectable. Even the Paragon 'tech' says that his ring gear teeth are slightly angled. Have you ever bought one from a vendor besides GM? Maybe I should look for an original one in the Driveline. Thanks for the response, Steve.Comment

like the dipstick, only time i've had to deal with worn teeth on the ring gear, i've just removed and reversed the gear. good luck,mikeComment

Steve:
The ring gear teeth should be straight cut (at least to the eye) as are the teeth on the starter pinion gear. If the teeth on your new ring gear are angled, it's wrong or it's a used one. That's what used ones look like after some time in service. The ring gear teeth wear more on the leading edge of the tooth where the starter pinion gear engages.
There's nothing wrong with shimming a starter to the bellhousing. I don't believe you'll find the procedure in a GM service manual but I'l try that after I verified the bellhousing was tight to the block or that there was no foreign material trapped between the bellhousing and the block.
If that doesn't work, put the old ring gear back on the flywheel. It won't affect the balance.Comment

Re: ..
Didn't the car come with a 153 tooth ring gear? Is the 168 tooth gear the problem?Comment

153/168 tooth count is a flywheel dia issue... *NM*

All C1's had 14" flywheels and 168-tooth ring gears, with bellhousing-mounted starters; nothing else will work on a C1.Comment

Re: ..
The smaller, 12 3/4in diameter, 153 tooth flywheel WAS NOT available on ANY Chevy V8 engine until the 63 models.Comment
