- Clean the following components:
• | Use solvent to clean the engine block. |
• | Clean the gasket surfaces. |
• | Clean the coolant passages. |
• | Clean the oil passages. |
- Inspect the following for cracks:
• | Inspect the cylinder walls for cracks. |
• | Replace the engine block if any cracks are evident. |
• | Inspect the coolant jackets for cracks. |
• | Replace the engine block if any cracks are evident. |
• | Inspect the main bearing insert cavities for cracks. |
• | Replace the engine block if any cracks are evident. |
- Inspect for the following in the cylinder walls:
• | Inspect for gouges in the cylinder walls if deeper than 0.05 mm
(0.002 in). |
• | Bore the cylinder if the gouges are deeper than 0.05 mm
(0.002 in). |
• | Inspect for pitting in the cylinder wall if deeper than 0.05 mm
(0.002 in). |
• | Bore the cylinder if pitting is deeper than 0.05 mm (0.002 in). |
• | Inspect for scores if the cylinder wall is deeper than 0.05 mm
(0.002 in). |
• | Bore the cylinder if scores are deeper than 0.05 mm (0.002 in). |
- Use a cylinder bore gage
to measure the cylinder bore for the following conditions:
- If wear and/or taper is less than 0.05 mm (0.002 in),
the cylinder must be reconditioned. Recondition the cylinders with less than
0.05 mm (0.002 in) of wear and/or taper with a hone and fit
with the appropriate size select fit piston, providing the cylinder was not
fitted with the largest size select fit piston. If wear and/or taper is over
0.05 mm (0.002 in) the cylinder must be bored.
