Subject: Front Axle Seal Leakage.

Front axle seal leaks may be due to flexing of the axle shaft during periods of extreme

loading. When the axle shaft flexes Seal (92-1774) may not be able to maintain contact

around the entire circumference of the axle shaft. If this occurs, under some conditions,

small amounts of oil can escape. Wheel bearing failure may also result if the oil dilutes

the grease in the wheel bearing

Axle Seal (99-6969) has been improved to maintain contact with the axle shaft when

flexing occurs. Axle Seal (99-6969) should be used whenever repairs to the front axle

are performed on any unit listed above. The seal should be installed in accordance with

the service manual and should be installed with the metal insert facing outboard. Coat

the outer diameter of the seal with a light film of oil during installation. A light film of oil

applied to the outer surface will ease installation and help prevent damage to the rubber

surface of the seal.

Note: Other machines that use the Dana GT20 axle may benefit from the use of this

improved seal (e.g. GROUNDSMASTER

200 and 300 series tractors).
