ENGINECOOLING This tractor has an air cooled engine . Air must be able to circulate freely around the engine , through the screen and shroud , and over the fins of the cylinder head and cylinderblock . Keep these areas free of accumulated dirt and trash or the engine will overheat and result in damaged moving parts . DRY - TYPEAIR CLEANER Incoming air for combustion is filtered by a dry - type air cleaner having a filter element inside of the cover . Remove and clean or replace the element with a new one when loss of power isnoticeable . Illust . 14 Removing the air cleaner filter element .

The reduced ground pressure and low inflation provides maximum protection for turf , soil , Keep the pnewnatic tires properly inflated . and crops . Underinflation will damage the tire cord body and may also cause the tire to slip on the rim , thus tea'ring out the tube valve stem . CAREOF TIRES Always see that the tire valve caps are in Avoid stumps , stones , deep ruts and other place and tightened securely to prevent the hazards .

CLUTCHAND BRAKE ( International Cub Cadet 71 , 102 and 122 Tractors ) As the clutch and brake are both operated by the same pedal , care must be taken to maintain a neutral zone so the clutch is dis - engaged when the brake is applied . ADJUSTINGTHE CLUTCH It is important that a clearance of . 050 - inch be maintained between the clutch release lever and the clutch release bearing . In order to maintain this clearance . the pedal should have a free movement of approximately 3 / 16 - inch . SeeIllust . 21 . This measurement is taken at the point of contact of the pedal arm withthe front edge of the pedal return stop . The clutch pedal adjustments are set at the factory and should not require frequent atten - tion unless the linkage has been disturbed or when the pedal movement becomes less than 3 / 16 - inch . When it is necessary to adjust the clutch , turn the adjusting nut " A " on the clutch release rod ( 1IIust . 22 ) in or out as required to get the proper measurements . ADJUSTINGTHE BRAKE The brake should engage when . the pedal arm is pressed down to within a maximum of l - 5 / l6 - inches and a minimum of 3 / 4 - inch dis - tance above the top of the left foot support , which serves as the pedal stop . SeeIllust . 21 . It may be possible to push the pedal all the way down to the pedal stop , but this is of no concern as long as the brake is engaged when the pedal arm is at least 3 / 4 - inch above the pedal stop .

Block the tractor so the left rear wheel is off the ground . Start the engine at half throttle or faster . Move the speed control lever to the forward position . The rear wheel should rotate in the forward direction . Depress the brake pedal all the way down and release .

If the engine is to be operated at temperatures between + 75 degrees F and 0 degrees F . this oil can be used for the first five hours of operation . If the temperatures are not within this range , drain the oil from the crankcase and replace it with new oil as specified in the " Lubrication Table " , The engine oil must be drained and replaced with new oil every 30 hours of engine operation thereafter . Oils designated " For Service MS " are recommended for this engine . To aid starting , the selection of crankcase lubricating oils should be based on the lowest anticipated temperature until the next drain period . Check the oil levels of the engine crank - case and transmission to see that they are filled to the correct levels . Note : Check the Illust . 26 oil level only while the engine is stopped .
