7. Measure the piston ring-to-piston ring groove side<br />
clearance.<br />
7.1. Insert the edge of the piston ring into the piston ring<br />
groove.<br />
7.2. Roll the piston ring completely around the piston.<br />
• If binding is caused by a distorted piston ring<br />
groove, MINOR imperfections may be removed<br />
with a fine file.<br />
• If binding is caused by a distorted piston ring,<br />
replace the piston ring.<br />
8. Measure the piston ring side clearance with a feeler gauge.<br />
9. If the side clearance is too small, try another piston ring set.<br />
10. If the proper piston ring-to-piston ring groove clearance<br />
cannot be achieved, replace the piston and pin assembly.<br />
11. To determine the proper piston ring side clearance, refer to<br />
<strong>Engine</strong> Mechanical Specifications.<br />
