IML: 413 rod knock etc

["mike and linda sutton" <mikanlin62@xxxxxxxxxxx>]

Well theres tons of degrees on the " right " way, the " best" way and all to 
do this.  If the cranks not grooved too deeply and you can rotate it down to 
get access by all means polish it.  Ive had great luck attaching abrasive 
material such as emery cloth to an old leather belt and using that to polish 
the journal.  The only danger to that is polishing too much in one area, but 
its doubtful youre going to seriously out of round the thing.  The hardening 
should be deeper than the depth youre polishing so that shouldnt be a huge 
problem.

My concerns...getting ALL and I mean ALL of the abrasive out of there 
afterwards.  Secondly,  if the cap bolt broke on the rod, the rod big end 
would be suspect to me.  If theres not enough bearing crush to hold the new 
bearing in,  its going to fail again.  The rod is the potentially worst 
thing here , if the large end is out of round or the thing has bent or 
twisted.

Good luck,

Mikey
