Cub Cadet 454 manual Maintaining Your Tiller, Engine, Cleaning The Tine Area, Belt Replacement

SECTION 7: SERVICING YOUR TILLER

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 30 ounces of Benalene 920 grease. Apply a bead of RTV or silicone sealant to the right half of the transmission, all the way around the gear compartment. Assemble the left half to it. This grease can be obtained at your nearest authorized dealer. Order part number 737- 0300.

Clutch Bail—Lubricate the pivot point on the clutch bail 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 Shaft—Remove tines at least once a season and lubricate with oil.

Wheel Axle—Remove the wheel assemblies at least once a season and lubricate with oil.

SECTION 8: MAINTAINING YOUR TILLER

WARNING: Disconnect the spark plug wire and ground it against the engine before performing any repairs or maintenance.

Engine

Refer to the separate engine manual for engine maintenance instructions.

Your engine is equipped with a oil drain pipe and cap located on the bottom right side of the engine which will help in draining the oil from the engine. Always drain oil when it is warm. To drain oil, remove cap and drain oil into a suitable container. Dispose of oil properly.

Maintain engine oil as instructed in the separate engine manual packed with your unit. Read and follow instructions carefully.

Service air cleaner every ten hours under normal conditions. Clean every hour under extremely dusty conditions. Poor engine performance and flooding usually indicates that the air cleaner should be serviced. To service the air cleaner, refer to the separate engine manual packed with your unit.

IMPORTANT: Never run your engine without air cleaner completely assembled.

The spark plug should be cleaned and the gap reset every 25 hours of engine operation. Spark plug replacement is recommended at the start of each tiller season; check engine manual for correct plug type and gap specification.

Clean the engine regularly with a cloth or brush. Keep the cooling system (blower housing area) clean to permit proper air circulation which is essential to engine performance and life. Be certain to remove all dirt and combustible debris from muffler area.

Cleaning The Tine Area

Clean the underside of the tine shield after each use. The dirt washes off the tines easier if washed off immediately instead of after it dries.

We do not recommend the use of pressure washers to clean your unit. They may cause damage to pulleys, bearings, or the engine. The use of pressure washers will result in shortened life and reduce serviceability.

Belt Replacement

CAUTION: Do not use an off-the-shelf belt.

Your tiller has been engineered with a belt made of special material (Kevlar Tensile) for longer life and better performance. It should not be replaced with an off-the-shelf belt.

If belt replacement is required, order belt by part number from your nearest authorized dealer.

the engine.
