TRANSMISSION LUBRICATION SYSTEMTM 5-3805-263-14&P-2T h e t a p e r b e a r i n g s o n t h e i n p u t s h a f t g e tlubrication from oil that is thrown by the directionclutches.The taper bearings on the shaft for the idler gearget lubrication through passage (6). Some of the oilfrom the direction clutches goes into hole (5) andthrough passage (6) to the taper bearings.The lubrication oil to the planetary transmissiongoes through passage (7) to the outside of the maintransmission shaft and through four drilled holes(8) to a small passage around the center passage inthe main shaft.PLANETARY LUBRICATIONThe main shaft has a tube installed inside it tomake a center passage. This center passage lets P1pressure oil go to the No. 7 clutch.The lubrication oil flows through a small passagearound the center passage in the main shaft. Drilledholes in the main shaft let lubrication oil (from thesmall passage around the center passage) go to thebearings of the planet gears.All other gears and clutches get lubrication fromoil thrown by the turning components or fromleakage from the shafts with pressure oil. Theleakage then goes to the transmission reservoir.SYSTEMS OPERATION2-14
