Flywheel Questions

How do I count the teeth on my flywheel? I'm haveing loud starting noises, and have tried shimming, but I still get the embarassing cranking noise. I have a crate 350/350 w/ 350TH.

O.K. I was told that I had to have the correct flywheel for the starter, so I want to check the teeth tosee if it is a 168. That is the correct teeth for a SB350 isn't it?Trying to solve a loud cranking noise, not zzzzzzing, or zzzzzzzzzzipping sound. Have checked tolerences already.

New starter because the old one was doing it too and I thought it was the starter. Besides how would you describe the noise to someone who hadn't heard it??????/

You may have a bad flywheel..


The 153 Tooth flywheel measures 12 and 3/4 inches and the 168 Tooth flywheel is 14 inches in diameter. That is 1 and 1/4 inches difference total and as a general rule the staggered bolt hole starter (168T) will not even touch the 12.5 inch flywheel (153T). The 153T starter (the straight accross pattern) is way to off to engage the 14" (168T) flywheel.




This is a 153 T (12.75") flywheel starter

1964 Chevy C-10 custom, 350/350 crate engine,headers,edelbrock intake, holley carb, HEI, 1 wire alternator,new radiator,new battery,completely new wiring,new starter,with 350 TH automatic. The starter was making the noise before I installed a new one. Thats why I replaced it in the first place.I have shimmed the starter to acheive the required tolerances, and the starter is the staggered bolt type.Still get the loud embarassing cranking noise, not associated with improper shimming.

The year, and staggerd bolt pattern tells ya it's got the 168 tooth flywheel. Earlier as duece had said, you almost can't get them wrong. The 158 tooth flywheel is used for small clutch(10.5")small flywheel application where bellhousing's are really small like in the camaro's and firebird's who have limited floor space. The 153 also used the straight bolt pattern.
