5. Measure the connecting rod small end bore

necting rod assembly.

6. Check piston ring gap by inserting piston ring
into cylinder horizonta lly. Insert a feeler gauge
in the opening between the ends of the piston
ring . (See Figure 3 -57.) If maximum ring gap
exceeds the Service Limits when measured at
the top and the bottom of the cylinder bore, re -
pi ace the ri ngs .
7. With the rings installed in their grooves, take
several measurements with a feeler gauge to
determine ring to groove clearance . If the
clearance exceeds the Service Limit in Figure
3 -58, replace the rings and remeasure ring to
groove clearance . If the dimension still ex-
ceeds the Service Limit, replace the piston .
