Piston And Piston Ring - Suzuki GZ250 Marauder Service Manual

3-59 ENGINE

PISTON AND PISTON RING

• First, install a spacer into the oil ring groove and then
install the two side rails . The spacer and side rails
do not have a specific top or bottom when they are
new. When reassembling used parts, install them in their
original place and direction.
A CAUTION
When installing the spacer, be careful not to allow
its two ends to overlap in the piston ring groove.
• Same way in which to distinguish the 1st and 2nd piston
rings:
1. Their ring face shapes are different.
2. The 1st piston ring's face is chrome-plated.
3. The 2nd piston ring appears darker in color.
• The 1st and 2nd piston should be installed with their
marks facing up.
• Position the piston ring gaps as shown.
NOTE:
Before inserting the piston into the cylinder, check that the
gaps are properly positioned.
