ISUZU Cylinder Liner Kit 5878135721 5-87813572-1 for NQR71 NPR71 4HG1T
ISUZU Cylinder Liner Kit 5878135721 5-87813572-1 Compatible with NQR71 NPR71 4HG1T Diesel Engine — OEM Standard Overhaul Component
Product Overview

The ISUZU Cylinder Liner Kit with OEM numbers 5878135721 / 5-87813572-1 is a precision-engineered replacement designed for ISUZU 4HG1T diesel engines, widely used in NQR71 and NPR71 series trucks. This core component kit for engine overhaul contains precision-machined cylinder liners 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 is 5878135721 / 5-87813572-1. The same series also includes 5878135720 / 5-87813572-0 and 5878102920 / 5-87810292-0. Some sources indie this kit 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 reciproing motion of the piston rings, causing increased clearance between the cylinder wall and piston, leading to oil consumption, reduced compression pressure, and power loss.

This cylinder liner kit is designed specifically for the 4HG1T four-cylinder engine. 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 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
Cylinder compression test below specifiion Liner inner diameter worn beyond limit
