Piston Ring: Testing and Inspection
1. Insert the piston ring into the cylinder bore.
2. Using a piston, push the piston ring a little beyond the bottom of the ring travel, 115 mm (4.53 inch) from the top of the cylinder block.
3. Using a feeler gauge, measure the end gap.
Standard end gap:
No. 1: 0.270 - 0.500 mm (0.0106 - 0.0197 inch)
No. 2: 0.350 - 0.600 mm (0.0138 - 0.0236 inch)
Oil (Side rail): 0.200 - 0.550 mm (0.0079 - 0.0217 inch)
Maximum end gap:
No. 1: 1.10 mm (0.0433 inch)
No. 2: 1.20 mm (0.0472 inch)
Oil (Side rail): 1.15 mm (0.0453 inch)
If the end gap is greater than maximum, replace the piston ring. If the end gap is greater than maximum, even with a new piston ring, rebore all the
4 cylinders or replace the cylinder block.
