1D-70 Engine Mechanical:
Installation
NOTE
• When installing the piston ring, be careful
not to damage the piston.
• Do not expand the piston ring excessively
since it is apt to be broken down.
1) Install the piston rings in the order of the oil ring,
second ring and top ring.
a) The first member to go into the oil ring groove is
the spacer (1).
After placing the spacer, fit the two side rails (2).
CAUTION
!
When installing the spacer, be careful not to
allow its two ends to overlap in the groove.
b) Install the 2nd ring (3) and 1st ring (4) to piston.
NOTE
1st ring (4) and 2nd ring (3) differ in shape.
NOTE
Face the side with the stamped mark upward
when assembling.
2) Position the gaps of the three rings and side rails as
shown. Before inserting piston into the cylinder,
check that the gaps are so located.
3) Install each piston and piston pin. Refer to “Engine
Bottom Side Assembly” (Page 1D-56).
