|||
Thickness of the new top piston ring is |
|||
2 | 1 | 8N-1234 Ring | Install the piston ring with the "Up-2" side toward the top of the piston. The intermediate piston ring must be installed with the green colored stripe to the right of the ring end gap. |
When the piston ring is installed in a cylinder liner with a bore size of |
|||
The increase in the clearance between the ends of the piston ring for each |
|||
Thickness of the new intermediate piston ring is |
|||
Width of groove in new piston for intermediate piston ring is |
|||
Clearance between the groove and the new intermediate piston ring is |
|||
3 | 1 | 7W-2221 Ring | The spring ends of the oil control piston ring should be assembled 180 degrees from the ring end gap. The white-colored portion of the piston ring must be visible at the ring end gap. |
