Service Manual

SECTION 12 WHEELS, TIRES AND CHAINS
CAUTION! Servicing the Power Shift Snowthrower will
require working with some
of the moving parts. To
prevent accidental starting of the engine
while
performing service, take the following precautions:
Rotate the ignition key to off and remove.
Pull the wire
off the spark plug.
Make sure the wire does not accidentally touch
the spark plug.
CAUTION! The Power Shift Snowthrower has the
feature of being able to be stood on the front housing
for service and storage. Always drain the fuel from the
tank prior to such service taking the following
precautions:
Drain
it outdoors and make sure the engine is cool.
Wipe up any gasoline that may have spilled.
Do not drain the gasoline near any open flame or
Do not smoke when handling gasoline.
spark.
WHEELS
Wheels Operation
The wheels used on the Power Shift Snowthrower are
one piece design steel wheels. They can
be used in a
driving modewhere the wheel is rigidly fixed to the axle
or in a free wheeling mode where the wheel is allowed
to spin on the axle.
Wheels Removal
1. To remove the wheels, simply remove the klik pin
from the wheel and axle and pull the wheel
off.

TIRES
Tires Operation
The tires used on the Power Shift Snowthrower are
a
special low pressure design which provides maximum
traction in nearly all conditions. The tires are tube type
and are 35.5 cm (14') in diameter and are 10.1 cm
(4")
in width on 61 cm (24") snowthrowers while thos on 71
cm (28”) and 81 cm (32") units have slightly large tires:
40.6 cm (16') in diameter and 12.7 cm (5") in width. Tire
pressure should be between
.5 and 1.0 kg/cm2 (7 and
15 psi) and be equal on both sides.
Tires
Service
If a puncture or flat occurs, The Toro Company
recommends taking the wheel and tire assembly
to a
tire professional for repair or replacement.
It is not
economically practical
to attempt servicing without the
proper equipment.
CHAINS
Wheels Installation
1. Before installing the wheel coat the axle with an
anti-seize compound
to prevent the wheel from
corroding
to the axle.
2. Install the wheel in the desired location; inboard
for free wheeling or with the klik pin through the
wheel and axle holes for
driving. See Figure 117.
Power Shift Snowthrowers
Chains Operation
Chains are available for the Power Shift Snowthrowers.
However, in most conditions the low pressure tires will
provide better traction.
In fact, in some conditions,
chains will actually decrease traction because they fill
the tread on the tire. If conditions exist where chains are
desired, they can be installed as follows.
