I'm getting ready to do a synchronizer shaft replacement on my 1997 3.8L. The gear on the synchro binded. No teeth missing, but four teeth kinda folded over. I also checked the gear on the cam. Examining through the synchro port, no teeth on the cam are folded over and they appear to be all there. Is the cam supposed to be harder than the synchro gear? Whats the wear rate on cam gears? could I just throw in a new synchro shaft assembly with new gear and be done with it? Has anyone gotten away with this before? I'm not really into the idea of removing the timing cover. Not on this car anyway. I'm open to opinions. BTW, this all started when I lost oil pressure out nowhere a few blocks from my house. That's when I figured out that the sychronizer was not driving the pump after I pulled it. No metal fragments were found in oil or filter

fIRST THING i WOULD DO SINCE SYNCHRO ASSY IS REMOVED IS FIND OUT IF YOU HAVE OIL PRESSURE. USING A 1/4 INCH 3/8 DRIVE SOCKET AND EXTENSION ENGAGE THE DRIVE ROD AND TURN THE PUMP WITH A DRILL OR AIR RATCHET AND SEE IF YOU HAVE OIL PRESSURE. REPLACE SYNCHRO ASSY AND FIRE IT UP.

DStark1 - My thoughts exactly. I have a high speed electric drill I will use for this. I just bought a mechanical gauge for the oil pressure. I am just going to going to swap that in where the sending the unit is and check while I am priming the pump. I talked to a buddy of mine who is well versed in cars. He is a walking encyclopedia when it comes to cars. He put my mind at ease when he told me that I should double check the cam gear to make sure all of the teeth are there, but typically the synchronizer gear in a stock motor is supposed to go first before the cam gear. I should be good, and thanks for the reminder about the oil pressure!
