SERVICE
section 5.3
HYDROSTATIC TRANSMISSION
When servicing any part of the hydrostatic
system, observe clean shop practices. A small
amount of contamination in the high pressure
circuit will cause damage to the system. Improper
hoses can cause injury. See your Steiner dealer
for quality service parts and service of the high
pressure hydrostatic system.
TRANSAXLE OIL LEVELS
(Serial No. 1001 - 2999 only)
After a period of time the level on the front transaxle
dipstick may show to be low even though there are
no apparent oil leaks. This condition could be
caused by a transfer of oil from the front transaxle to
the non-vented rear transaxle replacing the air cavity
in the rear transaxle.
Before refilling front transaxle to the top mark on the
dipstick, remove the “top plug” on the rear transaxle
and allow air to enter to equalize the oil levels in the
transaxles. After oil level is stabilized, replace the
plug and refill the front transaxle as needed.
Equalize oil levels any time an excessive amount of
oil, more than a quart (liter), needs to be added to
the front transaxle.
TRANSAXLE OIL LEVELS
(Serial No. 3000 -
only)
After a period of time the level on the rear transaxle
may be low even though there are no apparent oil
leaks. This condition could be caused by a transfer
of oil from the rear transaxle to the vented front
transaxle.
Add oil only to the rear transaxle to
bring it up to the top of the filler neck.
It is normal
for the front transaxle to appear over full if the filler
cap is removed. If oil appears to overflow from the
vent hose of the hydraulic system expansion tank,
contact your Steiner dealer for hydrostatic repairs.
Forward - Reverse Lever Tension
Adjustment
Tension is adjusted by tightening the spring-loaded
friction washers on the Forward - Reverse lever.
Tighten the friction washers to hold the lever in the
desired position under normal loads. When the
hydrostatic system is subjected to heavy loads, the
Forward-Reverse lever has a tendency to return to
the neutral position. Additional holding pressure from
your hand may be needed to keep the lever in the
desired position.
Neutral Linkage Adjustment:
Absolute neutral is when the tractor will not creep
with the engine running and the Forward - Reverse
lever in neutral. If the unit creeps it is necessary to
adjust the control linkage. Adjust the linkage by
removing the bolt at one end of the connecting link
and rotate the rod end one-half turn at a time until
the desired setting is reached. Shorten the rod if the
unit creeps forward or lengthen the rod if the unit
creeps backward. Tighten locking nuts when neutral
setting is correct. (see Photo 10)
