Cylinder Block

Checking piston ring gap
- Push ring squarely from above down to approximately 15 mm from bottom end of cylinder. To do this use a piston without rings.








Checking ring to groove clearance
- Clean ring groove of piston before checking.








Checking piston
- Measure approximately 10 mm from lower edge, at a 90° angle to piston pin axis using an external micrometer 75 to 100 mm.

^ Maximum deviation from nominal dimension 0.04 mm.

Nominal dimension go to Piston and cylinder dimensions.





Checking cylinder bores
- Using an internal dial gauge 50 to 100 mm, measure at 3 points in diagonal sequence horizontally - A - and vertically - B -.

^ Maximum deviation from nominal dimension: 0.08 mm.

Nominal dimension go to, Piston and cylinder dimensions.





Installed position of piston and piston/cylinder allocation
- Mark installed position and allocation to cylinder on piston head using chalk or waterproof felt pen.

Note:
^ Do not use a center punch or scribe, since the piston head coating will be damaged.
^ Installed location: Arrow on piston face points toward belt pulley side.
