Seems we only get to work on this project every now and again᠁ But so it goes with projects..🤷â€â™‚ï¸ Anyhow, freed up stuck oil pump from our 302 that had been sittin for a number of years.
Got a replacement camshaft and went press gear off of old cam and broke the gear.
Didn’t realize it was aluminum, seemed like removing it on a shop press was the best method,,,, not so much.
Casting # is 2194906 Looking online for another cam gear and not finding any I feel are the exact same ? Any suggestions ? Brian

I believe the same cam gear that fits a Chevy six will work. The cam gear that fits a Mercruiser 4 cylinder is also a close match to the Chevy- - - -it might need a little machining in the hub area to match up with the thrust plate correctly. New Mercruiser gears are dirt cheap on Ebay. Jerry

Jerry says it may work, but definitely not the same part number. Chevy aluminum gear is 3835473, GMC is 2194906.
'57 GMC 102, Original 347 V8, HydraMatic, 3.08 rear gear, added A/C, disk front brakes, HEI, AFB carb, '98 Honda Black Currant paint. T-boned and totaled 10/12 '52 GMC 152 Stake Bed, Original 228, SM420, added A/C, HEI, disk front brakes, '67 Chev 3.55 rear gear. Gets used as a real truck.
It would probably be necessary to compare the remains of the broken gear to a Chevy item, especially the position of the keyway and the timing marks. Diameter and tooth count would need to be exact, other details could be massaged if necessary. Jerry

Scroll down the ePay page and there are two more for less $$.
I'd trust Hollander on this.

For future reference, use a bearing splitter to spread the load over a wider surface of the gear when pressing it off. I consider stovebolt timing gears to be a one time installation piece- - - -it's risky to try to reuse one that's been installed before. The timing gear I'm going to use on my roller cam engine will be honed to be a snug slip fit and retained with a bolt and a heavy flat washer, since I'm planning to tinker with the cam timing with offset Woodruff keys.

I thought about the bearing splitter. But there really wasn’t any room between cam retainer plate and gear. Was pressed on there pretty tightly᠁ but I’m sure more experienced bolsters may have had better luck and gotten it off. Looks like maybe 50$ or so ᠁ so not bad
