•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.
