" The soft plugs in the ends of the shafts are a PITA to remove. We clean the shafts inside, but no one else ever seems to mention doing this necessary chore on a rebuild.


I've cleaned 3hree pair of such Packard shafts and other makes withOUT removeing the end plugs. Enter a string at one end thru existing bolt hole 4our times longer than the shaft. Use air pressure to blow/suck it thru the other end. Tie a small swatch of cloth to centre of string and draw it backwards and forwards thru the shaft. It is a bit time consuming but relieves the headache of dealing with the end plugs. clean the ends with a ice pick or something bent over 90 degrees.

I can get them fastidiously clean using that methid.


It amazes me that u have not found any excessive guide wear to the tune of .004 to .006 OVER the high end of spec. ESPECIALY on the exh. guides. UNLESS most of your engines have the EARLY 55 rockers with pee holes.
