Troy-Bilt Pony Operator's Manual page 10

Before inspecting, cleaning, or servicing the machine, shut off the engine,
wait for all moving parts to come to a complete stop, wait for the engine
to cool, disconnect the spark plug wire, and move the wire away from
the spark plug. Failure to follow these instructions can result in serious
personal injury or property damage.
Maintenance
Engine
Refer to the Engine Operator's Manual packed with your tiller for all
engine maintenance.
Tire Pressure
Check the air pressure in both tires. The proper air pressure is printed on the side of
the tires. Keep both tires equally inflated to help prevent the machine from pulling
to one side.
Lubrication
After every 10 operating hours, oil
or grease the lubrication points
shown in Figure 20.
Use a clean lubricating oil (#30
weight motor oil is suitable) and
a clean general purpose grease
(grease containing a metal
lubricant is preferred).
• Remove the wheels, clean
the wheel shaft and apply
a thin coating of grease to
the wheel shaft.
• Grease the back, front and sides of the depth regulator lever.
• Remove the tines and clean the tine shaft. Use a file or sandpaper to gently
remove any rust, burrs or rough spots (especially around holes in the shaft).
Apply grease to the ends of the shaft before installing the tines.
• Oil the threads on the handlebar height adjustment screws and the
handlebar attaching screws.
Hardware
Check for loose or missing hardware after every 10 operating hours and tighten or
replace (as needed) before using tiller.
Be sure to check the screws underneath the tiller hood that secure the transmission
cover and the Depth Regulator Lever to the transmission.
Transmission Gear Oil
Checking the Transmission Gear Oil
Check the transmission gear oil after every 30 hours of operation or whenever you
notice any oil leaks. Operating the tiller when the transmission is low on oil can
result in severe damage.
1. Check the gear oil level when the transmission is cool. Gear oil will expand in
warm operating temperatures and this expansion will provide an incorrect
oil level reading.
2. With the tiller on level ground, pull the Depth Regulator Lever all the way up.

SERVICE
3. Remove the hex washer
screw (1/4-20 x .500) and
flat washer (.28 x .74 x
.063) from the left side of
the belt cover and the hex
washer screw (1/4-20 x
.500) from the right side of
the belt cover. Remove the
belt cover. See Figure 21.
4. Thoroughly clean
the area around the
transmission cover.
5. Remove the four hex
screws (5/16-18 x .75)
securing the transmission
cover to the drive shaft
and remove the cover.
Locate the main drive
shaft below the cover. See
Figure 22.
6. The gear oil level is
correct if the gear oil is
approximately halfway
up the side of the main
drive shaft.
7. If the gear oil level is low,
add gear oil immediately.
If the gear oil level is okay,
securely reinstall the
transmission cover and reinstall the belt cover.
Tine
NOTE: When reinstalling the belt cover, be sure to engage the bail and hold it so that
Shaft
the drive belt is tight before attempting to reinstall the belt cover. This will enable
the belt to fall under the belt keeping mechanism built into the belt cover. Failure to
do so could damage the belt and/or belt cover.
8. When adding gear oil, use synthetic 75W 140. You may add gear oil with the
transmission cover off, or reinstall the transmission cover and pour through
the oil fill hole, located on top of the transmission cover and secured with
a plug.
9. While checking frequently to avoid overfilling, slowly add gear oil into the oil
fill hole until it reaches the halfway point on the drive shaft.
Changing the Transmission Gear Oil
NOTE: Transmission gear oil does not need to be changed unless it has been contaminated
with dirt or sand particles.
1. Drain the 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 belt cover
and clean and remove the
transmission cover as in
Steps 3-5 in Checking the
Transmission Gear Oil.
4. Remove the left-side
wheel by removing the nut
and bolt from the wheel
axle. See Figure 23.
5. Tilt the left-side wheel shaft into a drain pan and allow the gear oil to drain
out through the top of the transmission.
