Cylinder Block Assembly: Service and Repair
BORE HONINGCAUTION: This cylinder liner uses Fiber Reinforced Metal (FRM). Hone only as directed below.
1. Measure the cylinder bores. If the block is to be reused, hone the cylinders and remeasure the bores.
2. To hone the cylinder bores:
- Use only a rigid hone.
- Honing stone:
- GC-600-J or finer stone (for nonferrous metals)
- Pressure: 200-300 kPa (28-43 psi)
- Honing rpm: 45-50 rpm
- Honing thickness: Less than 0.02 mm (0.0008 inch). Do not hone more than 20 cycles
- Honing lubricant: Oil type
- Roughness of finished surfaces: VVV or 1.2S
- Honing pattern: 60 degree cross-hatch
CAUTION: Clean the honing stone every 5 cycles.
3. When honing is complete, thoroughly clean the cylinder block of all metal particles. Wash the cylinder bores with hot soapy water, then dry and oil immediately to prevent rusting.
NOTE: Never use solvent, it will only redistribute the grit on the cylinder walls.
4. If scoring or scratches are still present in the cylinder bores after honing to the service limit, rebore the cylinder block.
NOTE: Some light vertical scoring and scratching is acceptable if it is not deep enough to catch your fingernail and does not run the full length of the bore.
