The ISUZU Engine Cylinder Liner Set with OEM numbers 1-87811665-7 / 1878116657 is a precision-engineered replacement designed for ISUZU FSR32 series medium-duty trucks, compatible with 6HH1 diesel engines. This core component for engine overhaul contains precision-machined cylinder liners to restore the precision fit of cylinder walls.
The cylinder liner 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. This cylinder liner set is designed specifically for the 6HH1 six-cylinder engine.
- Restoring Standard Bore: Provides a new cylinder working surface, restoring the 115mm standard bore diameter
- Combustion Sealing: Precision fit with pistons and rings ensures high-pressure combustion gas sealing
- Oil Consumption Control: Works with oil control rings to prevent oil from entering the combustion chamber
- Efficient Heat Dissipation: Transfers heat from the piston crown to the cooling system
- Friction Reduction: Features a plateau honing pattern that retains oil for reduced friction during cold starts and sustained high-load operation
| 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 |

- Number Confirmation: This product number is 1-87811665-7 / 1878116657. Same-series variants include 1-87811665-0 through -9. Verify the specific number on the engine nameplate before ordering.
- Kit Contents Confirmation: This kit includes 6 cylinder liners for 6HH1 six-cylinder engines. Some kits may include pistons, piston rings, and piston pins. Confirm included components before ordering.
- Associated Components: When replacing the cylinder 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 components.
- Post-Installation Break-in: After new liner kit installation, the engine requires a proper break-in procedure — avoid high-speed and high-load operation during the initial period.
- 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. Improper operation may cause serious engine damage or safety incidents.
