Piston Rings - Hyundai Accent GL 2002 Manual

PISTON RINGS

1. Measure the piston ring side clearance. If the measured value exceeds the service limit, insert a new ring
in the ring groove to measure the side clearance. If the clearance still exceeds the service limit, replace the
piston and rings together. If it is less than the service limit, replace the piston rings only.
Piston ring side clearance
No.1: 0.04-0.085 mm (0.0016-0.0033 in.)
No.2: 0.04-0.085 mm (0.0016-0.0033 in.)
[Limit]
No.1: 0.1 mm (0.004 in.)
No.2: 0.1 mm (0.004 in.)
2. To measure the piston ring end gap, insert a piston ring into the cylinder bore. Position the ring at right
angles in the cylinder wall by gently pressing it down with a piston. Measure the gap with a feeler gauge.
If the gap exceeds the service limit, replace the piston ring.

low part of cylinder that is less worn out.
