- Material & Surface Treatment: Steel cylinder liner with chrome-plated surface — manufactured under ISO/TS16949 certified quality system.
- Fitment Verified: Direct fit for ISUZU NKR55 and NHR models with 4JB1T / 4JB1 diesel engines — cross-verified against ISUZU OEM parts catalog.
- OEM Cross-Reference Verified: Replaces ISUZU OEM numbers 5-87813194-1 / 5878131941; adjacent variant numbers 5878131940 / 5-87813194-0.
Data Note: This product currently lacks bench-tested installation success rate and durability data from fleet tracking. These should be supplemented after batch production testing. Industry standards referenced include GB/T 1150-2010 (Internal Combustion Engines — Wet Cast Iron Cylinder Liners) and ASTM E10 (Brinell Hardness of Metallic Materials).
Failure Symptoms (Indicating Cylinder Liner Replacement Is Needed)
- Excessive oil consumption — Increased clearance between piston rings and cylinder wall allows oil to enter the combustion chamber.
- White or blue smoke from exhaust — Typical sign of oil entering the combustion chamber.
- Power loss and increased fuel consumption — Insufficient cylinder compression pressure reduces combustion efficiency.
- Rough engine operation and knocking noise — Worn cylinder liners increase piston slap noise.
- Abnormal coolant loss or overheating — Liner seal failure may cause compression gas to enter the cooling system.

Installation & Maintenance Recommendations
IMPORTANT: Cylinder liner installation requires a hydraulic press or specialized tooling. Professional installation is strongly recommended.
Installation Guidelines (Refer to ISUZU 4JB1 workshop manual for exact specifications):
- Thoroughly clean the cylinder block bore; inspect for cracks, distortion, or corrosion.
- Measure the block bore diameter; confirm match with new liner OD (4JB1 standard block bore approx. 95mm).
- For chrome-plated dry liners, cooling with dry ice before press-fitting is recommended to reduce interference resistance.
- Press in evenly using a hydraulic press; refer to workshop manual for specified press force.
- After installation, verify liner top flange is flush with block deck surface (tolerance ±0.05mm).
- Measure installed liner bore to confirm roundness and cylindricity are within tolerance.
Maintenance Schedule:
- Inspect oil consumption and exhaust color every 20,000 km.
- Inspect liner wear at 80,000–100,000 km or upon signs of oil burning / power loss.
- Under normal maintenance conditions, 4JB1T liners can exceed 150,000 km service life (varies by operating conditions and maintenance quality).
