Product Description
ISUZU Cylinder Liner Kit 5-87813182-4 5878131824 for NHR55 4JB1
ISUZU Cylinder Liner Kit 5-87813182-4 5878131824 Compatible with NHR55 4JB1 Diesel Engine — Precision Liner Assembly for Engine Overhaul
Product Overview
The ISUZU Cylinder Liner Kit with OEM numbers 5-87813182-4 / 5878131824 is a precision-engineered replacement designed for ISUZU NHR55 series light-duty trucks, compatible with 4JB1 diesel engines. This product is a core component kit for engine overhaul, containing 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 5-87813182-4 / 5878131824. The same series also includes 5-87813182-0 / 5878131820. MAHLE brand same-series products are also available. Please verify the specific number 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.
This cylinder liner kit includes 4 precision-machined cylinder liners, designed specifically for the 4JB1 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 specification | Liner inner diameter worn beyond limit |

Important Fitment Warnings
- Number Confirmation: This product number is 5-87813182-4 / 5878131824. Same series includes 5-87813182-0 / 5878131820. Verify the specific number on the original part before ordering.
- Specification Confirmation: Before installation, measure the inner diameter (93mm), outer diameter (95mm), and total length (181mm) of the old liner for verification. If your removed liner has a different size or edge design, do not order only by the engine name.
- Kit Contents: This kit includes 4 cylinder liners for 4-cylinder engines.
- Professional Installation: Cylinder liner kit replacement is a core engine overhaul procedure involving cylinder boring and liner pressing. Must be performed by a qualified engine repair technician.
- Associated Components: When replacing the liner kit, it is recommended to also replace pistons, piston rings, piston pins, 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.
- Fitment Confirmation: Please confirm the engine model is ISUZU 4JB1 or 4JB1T. If unsure, send engine nameplate photos and old liner photos with measurements before ordering.

Installation Guidelines (Reference Workshop Manual):
Preparation:
- Confirm engine model (4JB1) and part number (5-87813182-4)
- Prepare tools: Special liner pressing tool, bore gauge, torque wrench
- Recommended to also prepare: Pistons, piston rings, piston pins, cylinder head gasket, connecting rod bearings, main bearings, intake/exhaust valve stem seals, and other overhaul配套 components
Removing Old Liners (Reference Steps):
- Remove the engine from the vehicle and place on an engine repair stand.
- Remove cylinder head, oil pan, and piston-connecting rod assemblies in sequence.
- Use a special liner puller to extract the old liners from the cylinder block.
- Thoroughly clean the cylinder block liner bores; inspect for cracks or damage.
Installing New Liner Kit (Installation Sequence):
- Inspect new liners: Check inner and outer surfaces for casting defects, burrs, or rust.
- Measure fit dimensions: Measure cylinder block liner bore diameter and new liner outer diameter (95mm) — confirm interference fit meets workshop manual specifications.
- Install new liners: Using a special pressing tool, press the new liners evenly into the cylinder block bores.
- Check liner protrusion: Measure liner top protrusion above the cylinder block deck surface — ensure it meets specification.
- Install piston-connecting rod assemblies: Install piston-connecting rod assemblies into the cylinders.
- Install cylinder head: Install new cylinder head gasket; torque cylinder head bolts to specification in correct sequence.
- Adjust valve clearance: Adjust valve clearance per 4JB1 engine workshop manual specifications.
Post-Installation Checks (Mandatory):
- Rotation check: Turn the crankshaft manually — confirm smooth rotation, no binding.
- Compression test: Perform compression test before starting — confirm even and standard cylinder pressures.
- Startup test: Start engine; check for abnormal noise, oil leaks, coolant leaks.
- Break-in operation: Follow proper engine break-in procedure.
Maintenance Schedule:
| Item | Interval | Notes |
|---|---|---|
| Oil change (post break-in) | First 500 km / 50 hours | Oil and oil filter must be changed after break-in |
| Regular oil change | Every 5,000～10,000 km | Use API-standard diesel engine oil |
| Compression test | Every 50,000 km | Check liner-piston ring sealing condition |
| Liner kit replacement | During engine overhaul | Depends on engine wear condition |
