Hello evryone,

I am rebuilding my 56 pan and today I noticed that my male connecting rod has a little slop in it. If I grab the rod at the top and rock it back and forth I see about 1/16 (maybe a little more) of motion from one side to the other. I want to wait until next winter to do the lower end. I did a complete top end this year. Do you guys think that this is excessive slop in the rod or do you think it could wait 6 months?

PS: The lower end was completely rebuilt in 92.

Thanks,

Panhd

 

Before you opened up the engine, did it have any bottom end knock after it warmed up? If not, and you don't ride crazy, it should be OK for 6 months.

 

threre was no lower end knock... I appreciate your opinion.. thanks

 

I thought side to side was ok,,,,up and down, should have no play....

 

Some side-side movement is OK. Too much or if the rod rocks side to side means trouble.

 

If youre going to wait till winter then park the bike.These engine cases arent cheap and a good set is getting harder to find.Why turn our bikes value into basket case status?

 

connecting rod side clearance is 0.006-0.010" anymore than that you'll have to rebuild the crankshaft. stick a feeler gauge inbetween the rod and crankshaft. don't grab them by the top and rock them back and forth, up an down (no play) from the rod downto the crankpin slide the rod on the pin, don't rock it. hope this helps.
