My 41 chevy coupe has a 216 engine with a harmonic balancer made to take a handcrank. AFter the engine was rebuilt and I put it back into the car, I had to use a hammer and block of wood to install the balancer (there are no threads in the end of the crank. I wasn't crazy about this method, but didn't see another option. NO way to use a bolt or anything to put it in. I didn't have to use a sledge or anything, just a small balpeen hammer. Some discussions I read online said this could be done with this type of balance. (And it's too late now that it's done!) My question is, what is it that holds the balancer in place now, since there are no threads in the end of the crankshaft for a retaining bolt of any kind, since it was made for a hand crank?

It is held by the keyway and friction.

It should have fit tightly and took a heafty hammer and several hits to get it on all the way.

Do bolts have to be installed when putting the balancer on to lock the weights in place and then remove them once its on?

Don, You don't use bolts to reinstall the balancer on the 216. I used a block of wood and a large sledge hammer, and tapped it lightly but firmly. I used about an 8 to 10 inch hammer stroke. The key that Chipper mentioned is used to align the balancer on the shaft.

yes mike you use two bolts to lock the balancer before you drive it on then remove the bolts make sure the bolts are not to long as it will damage the timing gear cover . when i get one that is not a snug fit i put a couple of drops of locktite on it . there is not much fore and aft thrust on the balancer but you do not want it loose .hope this helps

Mike: Don was asking about locking the weights in place with bolts when installing the harmonic balancer with a block of wood and a sledge hammer and then removing the bolts after the harmonic balancer was in place. This is done to keep the weights secure.

Thanks, for the update. I remembered that I also used a 1 and 3/4 inch socket to drive on the balancer. This protected the front of the balancer where the prongs stick out for crank starting the engine.
Thanks, Mike
