Cylinder head oil distribution system for certain Harley-Davidson motorcycle engines

摘要

An improved oil circulating system for lubricating engine heads of certain HARLEY DAVIDSON motorcycles includes a Y fitting connected to an oil outlet of the crankcase, a first oil tube extending from the fitting to an oil inlet of the rear head of the engine, a second tube extending from the Y connection to an oil inlet of the head of the front cylinder, and a plug for plugging an oil outlet of the head of the rear cylinder. To install the device, the original oil tube leading from the oil outlet of the crankcase to the oil inlet of the head of the rear cylinder is removed, and an oil tube leading from the oil outlet of the head of the rear cylinder to the oil inlet of the head of the front cylinder also is removed.
