How to install a balancer on SBC crank that doesn't have the threaded hole in the end for the tool?
Pre 1968 Chevrolet cranks do not have the balancer bolt hole in the end so you can use the balancer install tool to install the balancer. Are this just carefully hammered on? or is there another tool to use?

I have never seen a crank without a center bolt? Is this for the balancer or pulley's?

i don't recall seeing a non threaded crank.maybe the one you have is defected.if you insist on trying to put on the balancer it can be heated properly and installed.still no guarantee it will stay where you put it.

You are correct SB Chevies pre 68 had no bolt in the end of the crank. First off carefully inspect the keyway slot inside the balancer and on the crank snout for any excessive wear, be sure to use a new key. Second be sure the balancer oil seal area is not worn with grooves---they make slick repair sleeves for this fyi. Then apply thin coat of silicone sealer around inside of balancer so to seal against crank good, apply engine oil to the lip seal and to the sealing surface of balancer. If you have an old balancer you can go face to face and hammer away or just use a small piece of 2by4 and get after it. Once the balancer seats all the way the lumber will bark back at you and have a different feel when you hit it. The danger of just using a sledge against the balancer is that you will likely swedge one of the bolt holes for the pulley. Finally put on the pulleys and straight edge them for alignment to make double sure balancer is bottomed out.
