Installation & Maintenance
Important: Installation by a professional technician using specialized tools is strongly recommended. Cylinder liner installation requires a press or liner installation tool.
Installation Guidelines
  1. Inspect block: Confirm block parent bore grade stamping, clean parent bore inner wall
  2. Measure parent bore: Use inside micrometer to measure parent bore diameter
  3. Cool liner: Place new liner in refrigerator or dry ice for easier press-fit
  4. Apply sealant: Apply appropriate anaerobic sealant to liner outer wall
  5. Press liner: Use specialized installation tool and press vertically into parent bore
  6. Check protrusion: Confirm liner top protrusion above block deck meets OEM specification
  7. Measure inner diameter: Confirm liner inner diameter within 112.0 mm standard range
Maintenance Schedule
  • Every 10,000 km: Check oil consumption and coolant level
  • Every 50,000 km: Check compression pressure and cylinder balance
  • Every 100,000 km or when failure symptoms appear: Inspect cylinder liners
