Piston and Rod - Assembling

PISTON AND ROD - ASSEMBLING





CAUTION: Be sure the "Front" marking on the piston and the numbers on the rod and cap are oriented as illustrated.





Install the retaining ring into the pin groove on the "Front" side of the piston.





Lubricate the pin and bore with engine oil.





Install the pin.

NOTE: Pistons do not require heating to install the pin, however, the piston does need to be at room temperature or above.





Determine the piston diameter and obtain the appropriate ring set.

PISTON RING GAP - CHECK





CAUTION: Be sure the rings look like the illustration.





Position each ring in the cylinder and use a piston to square it with the bore.

A = 89mm [3.5 inch]





Use a feeler gauge to measure the gap.

Limits:

Ring Minimum Maximum
Top 0.4mm [0.0160 inch] 0.7Omm [0.0275 inch]
Intermediate 0.25mm [0.0100 inch] 0.55mm [0.0215 Inch]
Oil Control 0.25mm [0.0100 inch] 0.55mm [0.0215 inch]

PISTON RINGS - INSTALLATION





NOTE: The top surface of all of the rings are identified with the word "Top" or the suppliers "Mark"..

Assemble the rings with the word "Top" or "Mark" up.





Position the oil ring expander in the oil control ring groove.





Install the oil control ring with the end gap opposite the ends on the expander.





Install the intermediate ring.





Install the top ring.





Position the rings as shown in the illustration.
