Product Description
ISUZU Cylinder Liner Kit 5878135721 5-87813572-1 for NQR71 NPR71 4HG1T

The ISUZU Cylinder Liner Kit with OEM numbers 5878135721 / 5-87813572-1 is a precision-engineered replacement designed for ISUZU NQR71 and NPR71 series light/medium-duty trucks, compatible with 4HG1T diesel engines. This product is a core component kit for engine overhaul, containing cylinder liners and matching components to restore the precision fit of cylinder walls, thoroughly resolving issues such as oil consumption and power loss caused by liner wear.

Numbering Note: This product number 5878135721 / 5-87813572-1. The series also includes 5878135711 / 5-87813571-0 and 5-87810292-0 / 5878102920. Some sources indicate this product corresponds to a per-cylinder (1 cylinder) piston set assembly. Please verify the specific number and kit contents based on actual vehicle configuration.
Working Principle

The cylinder liner (also known as cylinder sleeve) is the core inner lining component of the engine cylinder block, directly cooperating with the piston and piston rings to form the combustion chamber working surface. During long-term diesel engine operation, the inner wall of the cylinder liner wears due to the reciprocating motion of the piston rings, causing increased clearance between the cylinder wall and piston, leading to oil consumption, reduced compression pressure, and power loss.

The cylinder liner kit typically includes the following components:

  • Cylinder Liner/Sleeve: The precision-cast liner body providing a new cylinder working surface, restoring standard bore diameter.
  • Piston: The matching piston that transmits combustion pressure to the crankshaft.
  • Piston Ring Set: Includes compression rings and oil control rings, responsible for sealing combustion gases and scraping excess oil from cylinder walls.
  • Piston Pin (Gudgeon Pin) & Snap Rings: Key components connecting the piston to the connecting rod.

Replacing the cylinder liner kit is one of the most critical steps in engine overhaul, effectively restoring engine power performance, reducing oil consumption, and extending engine service life.

Failure Symptoms

Inspect immediately if any of these symptoms occur:

Symptom Probable Cause
Significantly increased oil consumption; frequent oil top-ups required Worn cylinder liner; failed piston ring sealing; oil entering combustion chamber
Blue smoke from exhaust (oil burning) Excessive cylinder liner-piston ring clearance; oil entering combustion chamber
Noticeable power loss; poor acceleration Worn liner causing insufficient cylinder compression pressure
Hard starting, especially cold starts Reduced cylinder sealing; compression pressure below ignition requirement
Increased crankcase blow-by (breather smoking) Combustion gases leaking past liner-piston ring clearance into crankcase
Cylinder compression test below specification Liner inner diameter worn beyond limit

Important Fitment Warnings
  • Number Confirmation: This product number is 5878135721 / 5-87813572-1. The series also includes 5878135711 / 5-87813571-0 and 5-87810292-0 / 5878102920. Verify the specific number on the original part before ordering.
  • Kit Contents Confirmation: Kit contents may vary slightly between suppliers (whether piston, piston rings, piston pin are included). Confirm included components before ordering.
  • Professional Installation: Cylinder liner kit replacement is a core engine overhaul procedure involving cylinder boring, liner pressing, piston ring installation, valve clearance adjustment, and other complex operations. Must be performed by a qualified engine repair technician.
  • Associated Components: When replacing the cylinder liner kit, it is recommended to also replace connecting rod bearings, main bearings, cylinder head gasket, intake/exhaust valve stem seals and other overhaul配套 components.
  • Post-Installation Break-in: After new liner kit installation, the engine requires a proper break-in (run-in) procedure — avoid high-speed and high-load operation during the initial period.
