I don't know how much you could get away with,we don't allow any. If its more than .0002 I would have it ground.Bill

THANK YOU

Any progress on gettin' her back together yet?
|
Filed the rings last night...had to go with two different sets of bearings to get the proper clearance( standard and standard +1 x) bought the x bearings at the advice of machinist but ended up with .004 + oil clearance..gona put in a half shell standard and half x bearing. Second set should be here tomorrow should end up around .0035
|
That won't make it fit like the align bore is off?Not being a jerk,just truly curious.What exactly do those numbers mean,anyway :oops:
|
I need to ask somebody which half to put the thickest one in...upper or lower. The x b earing is a standard bearing with .001" extra clearance built into it..ordered those cause machine shop guy told me I should..then after it was align honed it looks like I didn't need them.
|
got it back up and running. Used Hinks method of ball mic'ng the bearing shells to check clearances. Ended up with .0029-.0032 on all the rods and between .003 and .0035 on the mains.Gona run it once or twice and yank it back out to inspect the bearings.
|
Looks like either the crank isn't straight across the journal, or the mains weren't honed right. Take your pick.
