Now I see the why of using the balance piece. Since the engine shop
balanced the internals of the engine, I wonder if I should have the fan &
extension balanced? (before putting it back on? & possibly use the balance
piece)
Also, I have yet to purchase the 6 bolts and nuts that hold the fan
extension on. I think proably I could do with 6 bolts bought at the
hardware (WITH THIN HEADS) AND 1 1/4" in length and 1/8 to 3/16"ths in
diameter. Or for $15 i could buy them from Moss. What do you think about
this?
Thanks, Paul Dorsey
