The Polaris 5135221 water pump shaft and oil impeller are specifically designed for the Polaris RMK 800 Dragon sled models produced in the year 2008. As essential components of the sled's cooling system, these parts ensure effective heat management during rigorous off-road riding conditions.
Description: Water Pump Shaft:The water pump shaft (5135220) is engineered from durable materials to provide reliable performance and longevity. The shaft is responsible for transmitting the power from the crankshaft to the water pump, enabling it to circulate coolant throughout the engine. It features a robust design, ensuring stability and resistance to wear and tear during high-intensity use.
Description: Oil Impeller:The oil impeller (5135221) is another crucial element of the cooling system, functioning to draw oil from the sump and force it through the engine bore for cooling while also supplying lubrication. The oil impeller features an efficient design that maximizes contact with the engine bore walls for effective cooling. This impeller is expertly crafted to maintain optimal oil flow and pressure, contributing significantly to the overall health and longevity of the engine.
Installation and Maintenance:Replacing the old or damaged water pump shaft and oil impeller with new ones is a crucial preventive maintenance task for your Polaris RMK 800 Dragon. These parts can wear out over time due to the continuous flow of fluid through the system. Timely replacement ensures the cooling system in your machine performs optimally and allows the engine to maintain consistent temperature, leading to a smoother riding experience and prolonging the life of the engine. Regular checks on these components can pay off in the long run by providing an early warning system for potential issues.
