Okay so let me start with the truck: 1985 F150 with 69 302 (originally 315w), 4x4, single cab, regular bed, DB Electrical PMGR starter for 164 tooth (manual)

I have been having constant starter issues. I had a buddy try to crank it over while I looked at the starter up under the truck. It was just popping out and hitting the flywheel but not lining up. I did some digging and came upon 157 tooth vs 164 tooth flywheels as well as 28oz vs 50oz imbalance.

I believe what I put on the truck is a 164 tooth 50oz imbalance flywheel. I know for a fact that I should have put on a 28oz flywheel and I'm just glad that I haven't driven the truck too much with the off-balance flywheel.

What I am not sure about is whether I should buy a 164 tooth or 157 tooth flywheel. My starting issues would make sense if the bellhousing is a "small bellhousing" or one for a 157 tooth flywheel and I am using the wrong tooth count. I am just trying to be 100% sure before I make the purchase. I remember the PO telling me how difficult it was for him to find a bellhousing to fit the engine.

Can anyone tell me from my pictures what bellhousing I have? I can pull it off if necessary i guess. I have checked every picture on here and it doesn't match any of the bellhousings with pictures on this site: Bellhousings Does anyone know any measurements I can do?






Can anyone confirm that this is in fact a 164 tooth 50oz flywheel?

Also, if I get the 157 tooth flywheel will I have to get a new clutch as well? My current clutch disc is 10 inches and the pressure plate is 12 inches in diameter.

 

Well, looks like if you were careful you could count the teeth in the picture.
