Maintenance & Adjustments; Lubrication - Cub Cadet RT 65 Operator's Manual

Maintenance & Adjustments
WARNING!
Disconnect the spark plug wire and
ground it against the engine before performing any
maintenance or repairs.
Maintenance
Engine
Refer to the separate Engine Operator's Manual for engine
maintenance instructions.
Tire Pressure
Check the tire pressure in both tires. Deflate or inflate both
tires evenly to 20 PSI. Be sure that both tires have the same air
pressure or the tiller will pull to one side.
Air Cleaner
Service the air cleaner every 10 hours under normal conditions.
Clean it every hour under extremely dusty conditions. Poor
engine performance or flooding usualy indicates that the air
cleaner should be serviced. Refer to the Engine Operator's
Manual for maintenance instructions.
Tines
Clean the underside of the tine shield after each use. The dirt
washes off the tines easier if rinsed off immediately instead of
after it dries. Always towel dry the tiller afterwards and apply a
light coat of oil or silicone to prevent rusting or water damage.
NOTE: Never use a "pressure washer" to clean your tiller. Water
can penetrate tight areas of the tiller and its chain case and cause
serious damage to the tiller.

Lubrication

Transmission
The transmission is pre-lubricated and sealed at the factory. It
requires no checking unless the transmission is disassembled. To
fill with grease, lay the right half of the transmission on its side,
add 22 ounces of Benalene 920 grease, and assemble the left
half to it. This grease can be obtained at your nearest authorized
dealer by ordering part number 737-0300.
Clutch Handle
Lubricate the pivot point on the clutch handle and the cable at
least once a season with light oil. The control must operate freely
in both directions.
Pivot Points
Lubricate all pivot points and linkages at least once a season with
light oil.
Tine Shafts
Remove tine assemblies and lubricate the tine shafts at least
once a season.
Wheel Shafts
Remove wheel assemblies and lubricate the axle shafts at least
once a season.
Adjustments
Belt Tension
WARNING!
Never attempt to make any
adjustments while the engine is running, except
where specified in the operator's manual.
Periodic adjustment of the belt tension may be required due to
normal stretch and wear on the belt. Adjustment is needed if the
tines or wheels seem to hesitate while turning, but the engine
maintains the same speed.
To adjust the tension on the belt, refer to Clutch adjustment in
Assembly & Set-Up Section.
After the belt tension has been adjusted, if the belt is excessively
stretched, you may need to adjust the idler pulley rod. This can
easily be checked.
With the engine off and the clutch control bail disengaged, shift
the gear selection handle to each forward mode. If the indicator
bracket touches the idler pulley rod — with the clutch control
bail disengaged — then an adjustment is necessary.
1. Disconnect and ground out spark plug wire against the
engine.
2. Remove the belt cover as described under Belt
Replacement in the Service Section.
3. Remove the hairpin clip and spring washer from the idler
pulley rod.
4. Move the idler pulley rod to the lower hole in the idler
bracket.
5. Replace the spring washer and hairpin clip.
6. Check clearance of the idler pulley rod to the indicator
bracket by shifting to each forward mode, as before.
