Neoprene construction gives the impeller a long working life under continuous engine cooling duty, resisting the wear that comes from constant rotation against the pump housing. The impeller kit includes lubricant and 2 O-rings along with installation instructions, so you have everything needed for a complete impeller change in one package.\u003c\/p\u003e\u003cp\u003eThis impeller uses a spline drive to engage the pump shaft and features 12 blades for consistent water flow through the cooling system. It measures 3-3\/4 inches in diameter and 3-3\/4 inches in width, with a 1 inch shaft diameter, matching the dimensions of the pump housing on Volvo D12, D13, and D16 engines. Replacing a worn impeller on schedule helps prevent overheating caused by reduced water flow, protecting the engine's cooling circuit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e

blades.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 17938-0001-P impeller?\u003c\/strong\u003e It measures 3-3\/4 inches in diameter and 3-3\/4 inches in width, with a 1 inch shaft diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does this impeller attach to the pump shaft?\u003c\/strong\u003e The 17938-0001-P uses a spline drive to engage and turn with the pump shaft.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 17938-0001-P impeller weigh?\u003c\/strong\u003e It weighs 1.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need to grease the impeller before installing it?\u003c\/strong\u003e Yes, greasing the 17938-0001-P before installation makes it easier to insert into the pump bore and gives the impeller added protection during the initial prime.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow often should the impeller be replaced?\u003c\/strong\u003e As a wear item in the cooling system, the 17938-0001-P and similar impellers are generally replaced at least once a year or sooner depending on engine duty, and it is worth keeping a spare on board.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a
