If a mower is mounted on the tractor, the mower must be lowered to facilitate removal of the filter. Remove the throw-away-can-type filter and replace with a new filter after the first 10 and 50 hours of operation, and every 100 hours of operation thereafter. The filters can be obtained through your Cub Cadet Dealer under part number 723-3014. To remove the filter, turn the filter counterclockwise using an automotive-type filter wrench. Before installing the new filter, apply a coating of oil on the filter gasket. Thread the new filter on by hand until tight enough to seat the gasket. Loosen the filter. Then turn it until the gasket contacts the base. Tighten the filter an additional 1/2 turn. Start engine and allow it to run for a few minutes. Shut engine off and check for leaks; check oil level in transmission case. AIR CLEANER Servicing Foam Pre-Cleaner Element Clean and re-oil foam pre-cleaner element at 1-month intervals or every 10 hours, whichever occurs first. Service more often under dusty conditions. 1. Remove wing nut and cover. (See Figure 33.) 2. Remove foam pre-cleaner element by sliding it up off the paper cartridge. A. Wash pre-cleaner element in liquid detergent and water. B. Squeeze dry in cloth. C. Saturate in engine oil. Squeeze to distribute oil evenly. D. Wrap in shop towel and squeeze to remove excess oil. Discard used element and replace with new one at least once a year. Figure 33. Air Cleaner Assembly 1. Wing Nut 2. Cover 3. Rubber Tube 4. Cover Plate 5. Paper Cartridge 6. Foam Pre-Cleaner Element 7. Base Backplate SERVICING PAPER CARTRIDGE This engine is equipped with a dry-type air cleaner element, which should be checked every 100 operating hours and replaced if dirty. It should be checked and if necessary replaced more often under extremely dirty, dusty conditions. Do not wash element in any 24 liquid or attempt to blow dirt off with air hose as this will puncture filter element. Carefully handle new element — do not use if gasket surfaces are bent or twisted. Check the following when installing a new element: (See Figure 33.) 1. Backplate must be flat on gasket of carburetor elbow. Replace backplate if bent or cracked. 2. Gasket surfaces of element must be flat against backplate and covered to seal effectively. 3. Seal on cover must be in place to reduce noise and vibration of the cover. Vibration can cause stud hole in cover to enlarge, thus permitting dirt to enter carburetor. 4. Wing nuts must be finger tight — do not overtighten. Properly cleaned and installed air cleaner elements are the best guarantee to continued long and satisfactory engine life. CLEANING ENGINE This tractor has an air-cooled engine. Air must be able to circulate freely around the engine, shroud and over the fins of the cylinder head and cylinder block. Keep these areas free of accumulated dirt and trash or engine will overheat and result in damaged moving parts. Periodically clean the inside of the side panels and grille insert for adequate cooling. This machine is designed to cool properly with the engine side panels in place. Operating the machine without panels in place may result in inadequate cooling. SPARK PLUGS A WARNING To avoid possible injury, be sure engine is off and cool before making any adjustment or repairs. ■^NOTE Remove all dirt from around the spark plugs before removing. To remove spark plugs, always use a spark plug wrench. Check gap after every 100 hours of operation. Replace a defective plug with a new plug. Set gap at .025 inch. (See Figure 34.) Tighten plug to 10-15 ft-Ibs. See your authorized dealer for the correct replacement plug. Figure 34 1. SparkPlug CLEANING OF CYLINDER HEADS Cleaning of the cylinder heads should only be done by your authorized Cub Cadet Dealer. This process is to be done to keep your engine properly cooled and at its peak efficiency. The* frequency of cleaning is dependent upon the type of fuel used. When leaded fuel is used the cleaning interval is 250 hours, and with unleaded fuel the cleaning interval is 500 hours. FUEL FILTER A WARNING Do not replace fuel filter when engine is hot. The engine is equipped with an inline fuel filter. Visually inspect the filter periodically. Replace dirty filter. LIGHTS Refer to "SPECIFICATIONS” when replacement of head lamp bulb or taillight bulb is necessary. A WARNING Do not change head lamp bulbs when hot or when engine is hot. A CAUTION Do not touch glass portion of head lamp bulb. Touching glass portion will reduce life of head lamp bulb. 25 To replace a head lamp bulb, refer to Figure 35 and remove the socket from the grille by rotating socket 1/4 turn. Pull old bulb assembly from socket and insert new bulb assembly. Place socket into grille and turn to lock in place. To replace a taillight bulb, remove socket from the back of the taillight by rotating socket 1/4 turn. Remove old bulb from socket and install new bulb. Replace socket into taillight and ...
