Aligning Piston Rings using the Piston
Remove the piston and measure the gap between the ends of the piston ring using feeler gauges. 3.
When checking the piston ring end gap, always refer to the specification table (see Pistons). 4.
Note
If the end gap is too large, replace the piston rings with a new set.
If the gap remains too large with new piston rings, both the pistons and liners must be replaced.
If the gap is too small, check the cylinder bore for distortion, replacing as necessary. DO NOT FILE
PISTON RINGS.
Repeat the procedure for the remaining piston rings. 5.
Piston Assembly
Clean the piston ring grooves and fit the piston rings to the piston. 1.
Note
The top ring upper surface is marked 'N' and can be identified by a chamfer on the inside edge.
The second ring upper surface is marked '2N' but is plain on the inside edge and has a bronze
appearance.
The oil control rings can be fitted with either face upward.

Piston Ring Identification
Note
Connecting rods may be fitted either way around. However, ensure all three are fitted the same way
in relation to the piston.
Fit the piston to the connecting rod, ensuring the assembly markers in the cap and rod will all be assembled
on the same side, when the piston arrows face the front of the engine. 2.
