Topping off Transmission
Gear Oil
1. Complete steps l-through-3 de¬
scribed in "Checking Transmission
Gear Oil."
2. Insert a funnel into the
filler/check plug hole.
NOTE: When adding only a few
ounces of gear oil, use API rated
GL-4 or GL-5 transmission gear
oil with a viscosity of SAE 140,
SAE 85W-140, or SAE 80W-90.
When adding a complete refill of
new gear oil after having
drained the transmission, refill
only with SAE 140 or SAE
85W-140 with an API of GL-4.
3. Slowly pour clean gear oil into
the transmission. Frequently
check the level so as not to overfill
the transmission. See Figure 5-6.
4. When the gear oil level is cor¬
rect, reinstall the filler/check plug
securely.
Changing Transmission
Gear Oil
The transmission gear oil does
not have to be changed unless you
know that it has been contaminated
by foreign materials such as sand,
dirt, or metal particles. Of course,
any internal repairs on the trans¬
mission would also require that the
gear oil be drained and changed.
1. Drain gasoline from the fuel
tank or run the engine until the fuel
tank is empty.
2. Drain the oil from the engine.
3. Remove the four bolts and
washers securing the transmission
cover to the front part of the trans¬
mission. Lift the cover and gasket
off the transmission. See Figure 5-7.
4. Remove the left wheel.
5. Lower the left axle down into a
drain pan and slowly tilt the tiller
to the left so the gear oil drains
from the top of the transmission
into the drain pan. See Photo 5-8.
6. Once gear oil has drained, tilt
tiller upright and reinstall wheel.
7. Reinstall the transmission cover
using a new cover gasket.
8. Add new gear oil—see specifi¬
cations in NOTE at left.
9. Add engine oil to the engine.
A
DANGER
Gasoline is highly flammable
and its vapors are explosive.
Follow these safety practices
to prevent personal injury or
property damage from fire or
explosion.
• Allow the engine and muf-
: tier to cool for at least two
minutes before draining the
tiller's gasoline tank.
• Do n°t allow open flames,
pf;;- sparks, matches or smoking
Hip in the area.
L • Wipe away spills and push
tiller away from spilled fuel.
• Use only an approved fuel
III
container and store it safely
out of the reach of children.
• Do not store gasoline in an
fig
area where its vapors could
ipf reach an open flame or
spark, or where ignition
sources are present (such as
' hot water and space heaters,
ifurnaces, clothes dryers,
stoves, electric motors, etc.)
