WARNING
• Check the gap using a wire feeler gauge. Adjust the
gap to .030 in. (0.76mm) by carefully bending the
ground electrode. See Figure 19.
• Reinstall the spark plug into the cylinder head.
Torque the spark plug to 18-22 ft. lbs. (24.4-
29.8N·m).
Engine Cooling
To ensure proper cooling, make sure the grass screen,
cooling fins, and other external surfaces of the engine
are kept clean at all times.
Every 100 hours of operation (more often under
extremely dusty, dirty conditions), remove the blower
housing and other cooling shrouds. Clean the cooling
fins and external surfaces as necessary. Make sure the
cooling shrouds are properly reinstalled.
Carburetor
In compliance with government emission standards, the
carburetor is calibrated to deliver the correct fuel-to-air
mixture to the engine under all operating conditions.
The high speed mixture is set at the factory and cannot
be adjusted.
If engine troubles are experienced that appear to be fuel
system related, check the following areas:
• Make sure the fuel tank is filled with clean, fresh
gasoline. Make sure the fuel tank vent is not blocked.
• Make sure the in-line fuel filter is clean and unob-
structed. Replace the filter if necessary.
• Make sure the air cleaner element is clean and all air
cleaner element components are fastened securely.
If after checking the above items the engine is hard to
start, runs roughly, stalls, or lacks power, contact your
Cub Cadet dealer to have the carburetor and fuel pump
inspected.
Fuel Line
Change the fuel line filter after every 100 hours of
operation. The fuel filter is located on the left side of the
engine in the fuel line. Note the orientation of the filter to
install the new filter correctly.
• Place a container below the filter to catch any spilled
gasoline and carefully clamp the fuel lines.
• Loosen the hose clamps to remove and replace the
filter.
Steering Maintenance
Steering Lubrication
The steering arms, pivot shafts, and axles must be
lubricated if ever the steering effort increases, or after
every 25 hour of operation. Lubricate using a pressure
grease gun and Cub Cadet 251H EP grease, or an
equivalent No. 2 multipurpose lithium grease.
• Apply grease through the lube fitting on the RH and
LH steering arms which are located at rearward end of
the two steering drag links. See Figure 20.
• Locate the lube fittings for the pivot shaft and axle on
the front of one end of the axle pivot bar. Apply grease
through the two lube fittings, then repeat to lubricate
the other end of the pivot bar. See Figure 20.
Cleaning Steering Gears
Once a year, or if a tight spot is experienced when turning
the steering wheel, remove the steering gear cover on
each end of the pivot bar and clean the two steering
gears.
• From beneath the cover base plate on each end of the
pivot bar, remove the three hex screws securing the
steering gear cover. Remove the covers and clean the
gears. It is not necessary to lubricate the gears. Refer
to Figure 20.
• Insert the tab of the LH steering gear cover into the
square hole in the LH base plate, position the cover,
and secure with the three hex screws. Do not over
tighten. Repeat to install the cover on the RH side.
Pivot Bar adjustment
If excessive play is experienced in the steering wheel,
check the pivot bar for forward/rearward movement.
1. Raise the front of the tractor and set it on jack stands,
so the front wheels are suspended above the ground.
2. Grasping the ends of the pivot bar, attempt to move
each end of the axle forward and rearward to check
for side play. There should be minimal or no side play.
