Assembly
• Remove hub oil seal assembly from package, fit
one half into hub and other into inner seal
housing as follows:
a. Do not remove seals from package until
immediately before installation. This
protects the super-finished seal faces from
damage and contamination.
b. Hub and oil seal housing must be clean.
c. Install face seal by means of special fitting
tool number E541. Pressure is applied
directly via the elastromeric part. For ease
of assembly moisten the bore and O-rings
with a water/spirit mixture (NOT OIL).
d. Press seal ring into hub/ seal housing using
even pressure on opposite sides of tool.
Ensure that the housing/hub surface 'A' lies
parallel to the seal face 'B'. The O-rings
must not be pinched in the hub/housing or
partially out of the bore.
• Assemble ring gear and ring gear carrier to-
gether and secure with ring gear retainer.
• Press hub outer bearing cone onto ring gear
carrier journal.
• Clean metal surfaces with a lint free cloth, apply
a thin film of clean oil to metal faces.
Note: Keep oil off of other surfaces.
• Support hub with chain hoist, and carefully push
into position on axle spindle.
• Assemble guide tube from assembly tooling E
539 onto axle spindle, carefully pushing into
position on axle spindle. Use bumper or soft
metal hammer from assembly tooling to ensure
annulus is driven on completely.
