1) had the bore alignment checked on the wbx case - everything is within .0005" of nominal (but we are talking about rods?) 2) 3) 4) "little spin"... now, i'm not a strong man... not sure how hard a little spin is :-) 5) my rods definitely seem to drop faster than that, but i'll double check (not enough oil? who knows...) And yes, i do have newly reconditioned rods and crank and they do seem to measure quite consistently (at least as consistently as i can manage). I have been able to procure a bonafide micrometer in the right sizes to check the journals... Thanks for the tips - unfortunately, in this case at least, i am a little (lot) more comfortable with the numbers than little spins and hard clunks. They will be a good reality check, though. -Damon --- Stan Wilder <wilden1@JUNO.COM> wrote: > Deciding a go or no go on the parts you are > describing is more elemental > that. > #1) Case bore is of first priority. > #2) Toque the case up with the main bearings and > crankshaft in it. > #3) The bearings should be oiled with about 40 wt > oil. > #4) Give the crank (without the cam in the engine) a > little spin from > either end and you should have about 5 to 7 > revolutions.
