Symptom
Oil leaks from the wheel
shaft oil seals.
Oil leaks from the rear
of the tiller attachment
housing.
Remedy
• An oil seal
is
worn
or
damaged.
Check
for
side-to-side
and vertical play in the
wheel shaft and replace seal.
• Give new seals time
to
lap in.
• Inspect the wheel shaft
for
minor
damage at the oil seal location:
• Inspect
for
corrosion,
pitting,
or
scoring.
• Use emery
cloth
to
remove any
minor
defects.
•
Attempt
to
seat the seal so that it
is
on
an
undamaged
part
of
the shaft.
• Replace the wheel shaft if necessary.
•
Determine
if
the
seal fits
loosely
in
the
transmission
bore
Contact
the
TROY-SILT
Technical Service
Department
for
a special seal.
• Be sure the transmission
is
filled
with
SAE 90
or
SAE 140 gear oil. A
lighter
viscosity
oil will cause leakage.
• Make sure that a
non-hardening
gasket sealer was applied
to
the
outside
diameter
of
the oil seal
prior
to
its installation.
• Make sure the
housing
bore has
no
nicks
or
scratches that
would
permit
oil
to
seep
out
between the seal and the housing.
If
the
leak
is
from
the oil seals
on
the tiller tine shaft:
• Make sure the seals have
non-hardening
gasket sealer
around
the
outside
edges.
• An oil seal is
worn
or
damaged; replace the seal.
• Inspect the
tiller
tine shaft
for
minor
damage
at the oil seal location:
• Inspect
for
corrosion,
pitting,
or
scoring.
• Use
emery
cloth
to
remove any
minor
defects.
• Replace the
tiller
tine shaft if necessary.
•
Check
for
sand holes
(imperfections
in the cast
iron)
or
cracks
in the
housing
cover.
If the leak
is
on
the left side
of
the
tiller
housing:
•
Apply
non-hardening
gasket sealer to each
of
the
tiller
housing
cover
screws
and
tighten
the screws.
• Replace any
worn
or
damaged
gaskets.
• Make sure the
housing
cover bore has no nicks
or
scratches
that
would
permit
oil
to
seep out.
• Make sure the
housing
bore has
no
nicks
or
scratches
that
would
permit
oil
to
seep
out
beteen
the
seal and the housing.
If the leak is
from
the rear bearing cap:
• Inspect the rear bearing cap:
•
Make
sure the screws are the
correct
length.
•
Apply
non-hardening
gasket sealer
to
each
of
the rear
bearing
cap
bolts
and
tighten
the bolts.
• Replace a
worn
or
damaged gasket.
•
Check
for
excessive play in
the
tiller
tine shaft.
