Ariens HYDROSTATIC S-12 - Transmission Oil Level

NOTE: Bottom of engine shown. FIGURE 10
Replace drain plug. Remove dip stick and refill crankcase
with 4 U.S. pints of oil. Check oil pn the dip stick to see that
the oil level is at the full (F) mark. Do notoverfill.
TRANSMISSION OIL GRADE AND VISCOSITY
Ariens Gard-N-Yard lOW-30 or an øquivalent detergent
type motor oil meeting the requirements of the American
Petroleum Institute <A.P.r.) Service Classification SE shoffld
be used. Oil viscosity (weight) should be SAE 10W-30 and is
recommended for year-round use.
TRANSMISSION OIL LEVEL
The hydrostatic transmission, differentiel and hydraulic
lift system all bperate from a common oil reservoir. Note that
the rear end is the oil reservoir. The oil level in the reservoir
should be checked every 25 hours of operation of mohthly.
A C AUTfON: Proper oil level is essentiel for proper
operation and protection against severe damage to
the transmission as well as dynamic braking.
Use the following procedure to check the transmission
oil level:
Thereafter, the filter should be changed every 100 hoUrs
or annually, whichever comes first. It is not necessary to
change the transmission oil.
Use the following procedure to change the transmission'
oil filter.
1. Drive the tractor onto level ground. Place a container
under the filter to catch oil spillage as filter is removed.
2. Unscrew and discard oil filter. Use an oil filter removal
tool if necessary.
3. Moisten the rubber gasket with oil ånd install the filter.
4. Siårt engine ånd cycle the hydraulic lift until it operates
smoothiy. This bleeds the air out of the transmission. Check
foriaaks.
6. Wipe dirt from around the oil level and filler plugs. See
Figure 8. Remove plug.
7. Add sufficient SAE 10W-30 motor oil so that the oil filis
the elbow. Install the filler plug.
1. Drive tractor onto level ground.
2. On tractors with hydraulic lift systems, move hydraulic
Control lever to the "DOWN" position until the lift cylinder
is fully retracted.
3. Move Control lever to park start, keeping engine at fast
idle.
4. Wipe dirt from around the oil level and filler plug. See
Figure 7.
5. Remove plug. Oil level should be to the top of the pipe
elbow at the filler plug, see Figure 11.
6. If necessary, use a small funnel to add sufficient SAE
10W-30 With SE classification motor oil to bring the oil up
to the proper level. Replace plUg.
Be very careful to prevent dirt and foreign materials from
entering the oil reservoir when checking or adding oil.
A CHANGE TRANSMISSION OIL FILTER
When the tractor is new, change the filter after the
first flve (5) hours of operation.
Be very careful to prevent dirt and foreign materials from
entering the reservoir or oil filter when changing the oil and
filter.
Be sure breather is not clogged. Wipe clean with a rag and
solvent.See Figure 11.
GREASE STEERING SYSTEM
Under normal conditions the steering system should be
lubricated every 50 hours of operation or quarterly whichever
occurs first. The following list of grease fittings are identified
in Figure 12. Wipe each fitting clean before and after
lubrication! Use a good grade of general purpose grease such
as Ariens Multi-Purpose grease.
Rotate steering wheel clockwise until the spindle arm con-
tacts the axie stop and fill gearbox until grease is forced out
around the cam follower adjusting screw.
