I could use a little more guidance rods only came in with .001 clearance ARC says to hand polish the crank to obtain the extra .015 clearance. Any idea I do not want to take the crank out of round this is a brand new never ran crankshaft.
It has to be done with a crank polisher in my opinion, most any machine shop will have a hand held belt polisher. chuck it in the lathe with low rpm's and your good
I talked to the machine shop I use but he is not certain about being able to do it with out seeing the crank. I also know he does not own a bore gage below 2''. He does not do any small motor work but does all my performance and stock outboard or I/O boat work for me.
Crank was polished and I came away with .0019 I put it together now I just have to call precision to see what recommended valve spring pressure to shoot for at current installed height I have 35 lbs. on the seat.
