A friend enlisted my help to work on his '63 Spyder.? I disassembled the engine completely.? Imagine my surprise when I removed the cam and gear assembly from the crankcase and lowered it to sit it on the floor and the cam gear just FELL OFF!!!!!!? So, what exactly does this mean?? ( I think I already?know, but I still want to hear what others' thoughts and opinions are anyway.)? Thanks a million.?? (PS- the cam gear has a GM part # on it.? Not sure about the cam.)

Randy- On my 140 that I drove for many years.... there was a odd, slight thunking noise that could
usually be heard at idle.... Since I knew the guy that had put the engine together, I asked him about it, and he said he didn't know, it was a mystery, and had always done that.  I didn't worry about it anymore and drove it for a very very long time. When it came time to rebuilding it, I discovered what that noise was. The cam gear had been sliding back and forth on the key way, and because of the helical gear teeth giving a slight thrust, it would cause the gear to slide forward and hit the bellhousing, and then be driven back to hit the case, causing a "donk a donk, donk a donk" type noise that could only be heard at idle. Moral of the story is the cam gear got loose, probably from not being pressed on correctly, but in my case, and yours, no harm no foul!! When its time to put the engine back together, be carefull about installing the new gear. I really like those OTTO cam gears even though they are total over kill, just more insurance that the engine wont have to come
apart again any time soon!!
