Larry's Shee Posted January 10, 2011 Report Posted January 10, 2011 how do i measure ea. of those? whats the tool called for measuring these tolerances? Side clearance is measured with feeler gauges , other two with dial indicater. Feeler gauges between rod and crank -side clr. The other two almost impossible to put in words see manual. You can check the big end brg by pulling /pushing on small end of rod. If it moves more than 1/4 of a pussy hair , you might have a problem. Same with side to side of small end. This is on of the few times that a man needs instructions .BUY a manual JMHO, your results may vary Quote
