VI. Advantages of the Kit's Compatible Products
All parts conform to J D OEM drawings, with dimensional tolerances meeting standards, and can be directly replaced for installation.
Cylinder liners are made of high-phosphorus alloy cast iron, wear-resistant and corrosion-resistant; pistons are made of silicon-aluminum alloy, high-temperature resistant and not prone to cracking.
Gaskets use multi-layer metal composite + fluororubber sealing to prevent oil and water leaks during long-term use.
Factory-tested for water pressure, dimensions, and sealing, suitable for overhauls in agricultural machinery, construction machinery, and generator sets.

Durable and reliable materials: The piston sleeve is made of high-strength alloy cast iron, the piston is made of high-strength alloy, and the bearing alloy layer is wear-resistant and impact-resistant. One-stop solution: Includes all core components required for the overhaul, covering the entire repair cycle even if additional purchases are made. Performance restored to factory condition, etc.: After repair, the engine can be restored to its original factory power level, resolving issues such as burnout, black smoke, and insufficient power.
