b.
Magnetic Screen.
427-C1740
(1)
Magnetic screen assembly is located on bottom right side of rear of transfer gear case. Oil from bottom of
transfer gear case flows through an inlet passage. As oil flows through screen, foreign particles in oil are
stopped by screen. This keeps foreign particles from going into transmission hydraulic system.
(2)
After oil flows through screen, oil flows through magnets. Magnets are installed on tube assembly so same
magnetic ends are next to each other. Smaller metal particles that pass through screen are captured by mag-
nets. Magnets will not allow metal particles to go with oil through transmission hydraulic system.
(3)
Oil then flows through tube assembly to transmission pump.
c.
Output Transfer Gear Lubrication. Oil enters output transfer gear case through a passage between Number 6
carrier and transmission output shaft. Transfer gear case also serves as a reservoir for transmission circuit. All
return oil goes to bottom of transfer gear case. Movement of output transfer gears in oil causes oil to be thrown on
all components.
