6-38. TRANSFER GEAR ASSEMBLY (Continued).
The drive gear bearings, and power driven shaft bearings are lubricated by splash from the drive and driven gears.
On some industrial power transfer gears, a force feed oil pump and tubes were added to supply additional lubricating oil
to the teeth of the drive and driven gears.
An oil filler pipe, with a breather cap is pressed into the top of transfer gear housing for adding oil to the gear
compartment. A plug is located at the lower rear side of the gear housing for draining oil, and the dipstick is located at
the rear left-hand side of the gear housing for checking the oil level.
The oil level in the transfer gear should be checked daily with the engines stopped or clutches disengaged. Keep the
oil level to the FULL mark on the dipstick.
