Product Overview

• Part Number: 612600900078A
• Product Name:  Engine Power Core Cylinder Liner Kit
• Compatible Brands: WEICHAI

Applications

Product Features

• High-precision fit: Original equipment ufacturer (OEM) components utilize a "group matching" process to ensure the piston-cylinder liner clearance is at the micron level, minimizing leakage.
• Superior wear resistance: The cylinder liner inner wall undergoes a textured honing process, and the piston rings feature molybdenum spraying or ceramic coating, providing exceptional high-temperature and wear resistance.
• Perfect thermal perforce: The piston employs an internal cooling oil passage design, capable of withstanding high-pressure conditions and preventing cylinder scoring or crown melting at high temperatures.
• Fuel economy: Extreme sealing reduces power loss, contributing to the high thermal efficiency of Weichai engines.

Maintenance

When replacing key components during a major overhaul, be sure to simultaneously check the following parts to prevent rework:

• Connecting Rod Bearings: Check for peeling or burning.
• Connecting Rod: Check for wear on the small end bushing and deformation of the connecting rod body.
• Cylinder Head Gasket: This is a "replace-on-ded" part; genuine parts must be used to ensure a proper seal.
• Injector: Check the injector atomization to prevent dripping that could cause carbon buildup on the new piston or cylinder scoring.
• Coolant Pump and Piping: Ensure proper circulation to prevent localized overheating that could lead to premature wear of the new parts.
