Was it necessary to use a tool to ensure the seal in the timing cover was centered around the harmonic balancer before tightening the timing gear cover to the engine? This procedure is shown on page 6-32 of the 1954 truck Shop Manual. Does everyone do this?
I had to reinstall the cover on my ‘59 235, and the tool is necessary. There is enough slop in the cover bolts that the seal wouldn’t be centered. I made one on my lathe out of wood.
