The cooling system of your motorcycle helps maintain the optimal operating temperature in the engine. It includes a water pump that circulates coolant inside the system for more efficient heat exchange between the motor and radiator. The fluid, which consists of antifreeze and distilled water, runs through special passages inside the engine block absorbing heat from the combustion process. When this hot coolant runs through the radiator, excess heat dissipates into the atmosphere. A typical motorcycle water pump includes two seals that separate motor oil from the coolant. Over time, these seals can wear out resulting in the reduction of coolant level in the reservoir.
Another telling sign of bad water pump seals and gaskets is a somewhat milky color of motor oil. It means that it contains coolant. Also, if you notice leaks of coolant or lubricant from the special “weep” hole at the bottom of the water pump, then the assembly needs service. On the digital shelves of our online store, you can find everything that you may require to restore the operation of your cooling system. We offer only high-quality, durable, and reliable motorcycle water pumps and components from such well-known manufacturers as Pro Circuit, K&S Technologies, Boyesen, Outlaw Racing, and others.
A typical motorcycle water pump consists of an impeller and pump cover. An impeller shaft sits inside the right-side engine’s case cover. This shaft is actuated by the primary gear of the engine crankshaft. Since you need to remove the case cover to service the pump, a repair kit usually contains a case cover gasket, water pump cover gasket, inner and outer seals for the pump shaft, a bearing, and washers. If your impeller and its shaft show signs of wear, you can replace them as well. Our intricately designed impellers are made of lightweight, durable cast aluminum. They can increase coolant flow and extend the useful life of the engine.
