MANUAL TRANSMISSION LUBRICATION SYSTEM Abstract of the Disclosure A transmission having a gravity feed and centrifugal pressure lubricating system. Rotating drive and output gearing throws oil to a primary collector for gravity feed down in a first passage in the housing to a through-bore in the output shaft and for feed upward in a second passage to a blind bore in the input shaft. Rotating high-speed gearing throws oil to a secondary collector for gravity feed in a second passage to the blind bore and then to the through-bore. A plastic disc- having a central aperture smaller than the shaft bores, is fixed and sealed in a chamber between each passage and each bore end. A disc resiliently engages a plastic ferrule in each open bore end to seal the disc to the shaft and to permit gravity flow of oil through the central aperture into the bores and to retain an annular body of oil in the bores during shaft rotation and to centrifuge the oil through radial ports to lubricate the drive gear bearings.
