Gasoline Powered Generator Piston Assembly Kit | Replacement for 190F / GX420 | High Hardness Aluminum Piston with Rings & Springs | Farming/Aquaculture Equipment Parts

Produktbeschreibung

Robust Aluminum Construction - Piston assembly kit features aircraft-grade aluminum material with hardness rating 85HB, ensuring 3X longer lifespan than standard cast iron pistons. Ideal for high-RPM 190F/GX420 motor units in extreme conditions. Accurate Engineered Fit - Each piston undergoes CNC machining with ±0.01mm tolerance, guaranteeing smooth compatibility with 190F/GX420 motor units. Eliminates oil leakage and performance loss common in generic replacements. Complete Restoration Kit - Includes 5 chrome-plated piston rings (1 oil ring, 2 compression rings) and 2 heat-treated clamp springs. Restores 98.7% compression efficiency based on SAE J1349 testing standards. Multi-Industry Application - Proven sturdiness in farming irrigation pumps (200+ hours continuous use), marine generators, and forestry equipment. Withstands -20°F to 300°F temperature ranges. No-Risk Replacement - Backed by 12-month coverage against manufacturing defects. OEM-equivalent dimensions (ø70mm bore, 75mm stroke) ensure drop-in installation without motor unit modification.
