4.3.5 Inspection of liner after removal from engine block
Scale Deposits in coolant area
- If scale formation on the OD of the liner exceeds 0.5 mm, it should be
removed by wire brushing. In addition, when the engine is put back into
service, a descaling agent should be added to the cooling system to remove
scale from the rest of the system. DO NOT use acid solutions for descaling.
Dye Penetration Test
- Cylinder liner flanges should be checked for cracking by using a dye
penetrant. A new liner should be installed if any cracks are found. Make
sure that the liners are clean before using the dry penetrant, otherwise
false indications could occur.
4.3.6 Reassembly
- Paint SDC 402 COAT or equivalent anti-rust epoxy paint on the jacket side
surfaces of liner.
- Install new liner o-rings.
- Coat the upper and lower bores in the block with a silicon compound.
