Service Manual
Fluids/Greases
The fluids used in HYDRO-GEAR products have been
carefully selected, and only equivalent or better products
should
be
used.
Typically, an engine oil with a minimum rating of
55
SUS
at
210
F
and an
API
classification
of
SWCD is recom-
mended. A
2OW-50
engine oil has been selected for
use
by the factory.
The grease used in the manufacture of Hydro-Gear
products
is a Rykon Premium grease
and
should
be
substituted for with equivalent products only
if
it is
not
readily available in your area.
NOTE:
This grease
is
not compatible with all grease
types.
Safety Precautions
Certain procedures may require the vehicle to
be
dis-
abled
(wheels
raised off the ground, engine discon-
nected, etc.) in order to prevent possible injury to the
technician
and
bystanders.
Some cleaning solvents are flammable.
To
avoid
pos-
sible fire, do not use cleaning solvents in an area where
a source of ignition may be present.
The
loss
of hydrostatic driveline power may result in the
loss
of hydrostatic braking capacity. Proper brake main-
tenance
becomes
very important should
this
condition
develop.
Maintenance
Check the transaxle cooling fan for broken or distorted
blades,
and
check to
see
that the fan
is
securely fas-
tened. Replace the
fan
if
damaged.
NOTE:
Not all vehicles are equipped with a cooling fan,
refer
to
your vehicle manual.
Keep
the transaxle clean. Grass clippings and dirt will
effect the cooling efficiency of the fins on the housing.
Avoid high pressure washing, compressed air is the
preferred method
of
removing loose debris.
Inspect
the brake for proper operation.
If
the brake fails
to stop the vehicle or hold on a
30%
slope, adjustments
are necessary. You should also make sure it
fully
disen-
gages
when the
pedal
is
released.
Check to make sure the bypass actuator and linkage
is
operational. The bypass must be fully released during
operation of the vehicle.
Inspect
the transaxle for leaks at lip seals or damage to
the housing.
Check the oil level and add oil as necessary to bring it up
to the proper level.
