Flywheel Bolt Installation

Recommended Posts


If I remember correctly you slide the flywheel onto the crank, install the belleville washer or lock washer if there is no belleville washer. Install the nut and torque to proper amount.

There is never anything between the engine and flywheel because the shaft is tapered and that is what stops motion of the flywheel and holds it in position. The key in the shaft is only to position the flywheel, not to prevent rotation. The seating on the tapered shaft and proper torque is what prevents rotation, not the key.

I had the flywheel off my 243431 about 25 years ago, and after reassembly have not removed it since.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
