To Replace Belt:
1. Turn off the engine and remove the ignition key. Set the
parking brake. Raise the hood and allow the engine to
cool.
2. Loosen the tensioning rod jam nut (Fig. 34).

Changing Coolant In Cooling
System
The cooling system must be filled with a 50/50 solution of
water and permanent ethylene glycol anti-freeze. After
every two years, drain the coolant from the radiator,
reservoir expansion tank and engine by opening the drain
cock and block plug. After coolant is drained, flush the
entire system and refill it with a 50/50 solution of water and
anti-freeze. Capacity of cooling system is approximately 7
quarts (6.4 l). When filling, fill the radiator completely and
fill the expansion tank to between the marks. DO NOT
OVERFILL. Always install radiator cap securely.
Caution
If engine has been running, pressurized hot
coolant can escape when radiator cap is
removed and cause burns.
Adjusting Transmission For
Neutral
The machine must not creep when traction pedal is
released. If it does creep, an adjustment is required.
1. Park machine on a level surface and shut engine off.
Depress only the right brake pedal and engage the
parking brake.
2. Jack up left front side of machine until tire is off shop
floor. Support machine with jack stands to prevent it
from falling accidentally.
3. Lift seat. Visually inspect traction linkage for possible
binding condition, correct if necessary and check
machine operation. if condition still exists, repeat steps
1 and 2 and proceed to step 4.
4. Loosen (2) locknuts securing pump plate to mounting
plate. This will allow plate to move freely (Fig. 36).
5. Start engine and rotate pump plate (Fig. 36) in either
direction until wheel ceases rotation.
6. Stop engine and tighten locknuts to secure pump plate
(Fig. 36).
7. Start engine and check adjustment. Repeat adjustment,
if necessary.
