Machine and Hone Cylinder Liner

- Measure Bore diameter
- Determine and set machining tool

NOTE:
^ The bore diameter corresponds to the cylinder bore diameter (D) less the material allowance for the honing operation.
^ The material allowance for honing should in this case not be more than 0.05 mm.

- Select the repair size diameter (D) from the existing pistons (A, X, B).
- Machine Cylinder bore and Hone according to specified data
- Chamfer cylinder, refer to Chamfering Cylinder Bores
- Specifications of cylinder bore
