Output Flange fork or Oil Sealer Box
Output Shaft Bearings.
CAUTION
HOLD THE SEAL ONLY ON THE OUTER
DIAMETER. DO NOT TOUCH THE LIPS IN
THE INNER DIAMETER OF THE SEAL. IF
YOU TOUCH THE LIPS ON THE INNER DI-
AMETER OF THE SEAL, YOU WILL CON-
TAMINATE THE LIPS AND CAUSE A LEAK
BETWEEN THE SHAFT AND THE SEAL.
Do not apply pressure after the ange of the
seal touches the top of the cage or you will
damage the seal.
1. Prepare the seal for installation.
A. Apply axle lubricant to the inner bore of the
output bearing cage or the outer diameter of
the new oil seal.
B. Place the oil seal into the cage so that the
angeisparalleltothetopofthecage.
C. Use a press and sleeve, or a mallet and
sleeve, to install the seal into the cage. The
seal is correctly installed when the metal
angeofthesealseats onthe topof the
cage. Figure 5.100.
NOTE: The gap cannot be measured in the
RT-40-145. The seal seats below the lip.
D. After the seal is installed, a gap of 0.015-
0.030-inch (0.381-0.762 mm) can exist
betweentheangeandthecage.Thegap
isanormalconditionbecauseoftheex-
iblecoatingontheangeoftheseal.Use
a feeler gauge to measure the gap around
thecompleteange-to-cagearea.
•Ifthegapvariesmorethan0.010-inch(0.254
mm) between the highest and lowest mea-
surement, remove and reseat the seal. Fig-
ure 5.101.
2. Inspect the fork surface.

rosion or a wear track from the previous oil
seal. Replace the fork if any of these condi-
tions exist
B. Inspect the lead chamfer of the fork for nicks
and burrs which may damage the sealing lip
during installation. Use an emery cloth to re-
pair nicks and burrs.
C. Wipe clean the fork sealing surface and
face.
