crankshaft bolt on damper turning tool
 

I have seen this tool but have not found it for sale. Who sells the SBC three bolt flange tool with large hex that is an engine turning tool?

Summitracing shows one.

that is it, Thank you, I knew I had seen it but needed your help

Looks good. Is this installed temporarily or left on all the time? My balancer bolt has a 1/2 inch fitting in the center but it's hard to get a wrench in there with the pulley and radiator on.

Temporary installation or use.

I already have one, but it is a pita to unbolt the pulley to use it. Thinking about using three long studs for the pulley so I can simply slide it on without loosening anything. Weary of banging on the starter to adjust valves.

I just run the bolt in the end of my crank in with my 1/2" drive impact wrench. I have a long handle 1/2" drive swivel head ratchet to turn it. It's the same length as a 1/2" drive breakover. I can turn mine backwards without the bolt coming loose.

What is wrong with bumping the starter to set the valves? Been doing it over 40 years with no issues. I have a button next to my hood latch plate for that.

Look at the ARP bolts - they have some with either 12 point long heads, and some that have a 1/2" square drive hole inside, along with a big hex outside.

With my specific need, while on the dyno, no pulleys are installed and the flex plate is inaccessible because of the dyno mounting.

Because of the heavy valve spring load, I do not like the "feel" of the 7/16 center bolt. The above tool will work perfectly in this situation.

This dyno does not allow the engine mounted starter to fit, it has it's own starter and does not "bump" with the control as well as the engine mounted one.

The above tool will let me utilize the above said long ratchet.

And as stated above, in my experience, "bumping" the engine mounted starter is completely acceptable.

:"Bumping" the starter will work, but you can't really control where it will stop. I prefer to do it manually.
