Re: Clutch Fan on Packard V8

Your fabricated steel brackets look just like the ones I have which mounted a Lehigh compressor.

BTW, has anyone ever tried to have the Lehigh compressor serviced? It looks just like the ones used in thousands of small in-store coolers fifty years ago.

Since I go to Lehigh, PA a couple of times a year, I thought I would look them up. Absolutely nothing comes up in an extensive web search. They must have gone out or merged way back before google.

thnx, jv.

The photos I have seen did not have any accessories or torque converter installed.

"The engine is motored sufficiently to indicate the amount of unbalance, at which point rotation stops and the prescribed amount of unbalance compensated for by automatically drilling into the crankshaft pulley and welding a slug onto the flywheel. As a result, the stack-up of tolerances that otherwise might accumulate during the assembly of the engine is reduced to not more than 1/4-inch-ounces, thereby insuring precision balancing of every engine."

thnx, jack vines

Greetings, Eric, et al,

The front balance dampers are not really interchangeable. Packard assembled their engines, then ran them on a test stand and final-balanced them by drilling holes in the front damper and flywheel or welding weights on the flex plate.

Having said this, I have interchanged them many times when everything else was rebuilt, thus changing the fine tuning Packard did originally.

This probably needs its own thread, but 4 of 5 of the engines I pulled down had the balance damper cracked down the keyway. I have developed a kit to fix the crack and change the front seal to neoprene.

thnx, jv.
