CLEANING ELEMENT WITH AIRCLEANING WITH WATER: Using clean water, at a pressure not to exceed 40 PSI, proceed as follows:Direct water at an angle against the inside (engine side) of the element to loosen any imbedded dirt. Best results can be obtained by using a water hose without a nozzle and moving it so that water is directed at an angle along the complete length of each pleat. Wash off loose dirt by directing water against the outside of the element. Repeat this procedure until the element is clean. Make certain that no dirt is on the engine side of the element, and thoroughly dry the element before installing it.
CLEANING ELEMENT WITH WATERCLEANING WITH DETERGENT: Some oily and/or sooty deposits can be removed by washing the element in a solution of warm water and a good household non-sudsing detergent. Rinse with clean water and thoroughly dry the element before installing it.
WASHING ELEMENT WITH DETERGENTINSPECTING ELEMENT:1. Hold a lighted electric bulb inside the dried element and carefully inspect the element for tiny, pinpoints of light. Any light showing indicates a pleat has ruptured and will tear with further use. Discard the element.2. Wrap usable elements in sealed plastic bags.3. Store the wrapped element in a dry, clean place.
INSPECTING ELEMENTWhen equipped with oil bath type air cleaners, accumulation of dirt and/or oil in the air cleaner outlet pipe is an indication the air cleaner is not being serviced or functioning properly. Refer to manufacturer's recommendations for servicing.Valve Lash Setting
Check Valve Lash Setting With Engine Stopped:1. Remove the flywheel timing cover from the flywheel housing. Rotate the engine flywheel in direction of engine rotation, so the flywheel timing pointer is at the TC 1-6 cyl. mark on the flywheel. Remove the bolt from the flywheel timing hole and insert timing bolt (long bolt which fastens cover to flywheel). 2. Remove the valve cover and observe the positions of the No. 1 and No. 6 cylinder valves and the camshaft lobes to determine which cylinder is sealed for compression.3. Turn adjusting screw counterclockwise 2 clicks or more to provide clearance between rocker assembly and valve.4. Turn adjusting screw clockwise to obtain zero lash. There should be no free rocker movement or adjusting screw button lateral movement.
VALVE ADJUSTMENT The adjusting screw button can still be rotated by finger pressure even when it is in contact with valve stem and clearance is zero. Turning the adjusting screw clockwise beyond this point will force the valve off its seat, and final lash setting will be incorrect.
VALVE CLEARANCE SETTINGS5. Turn adjustment screw counterclockwise ten clicks (.020 in.; 0,50 mm) for exhaust valves and four clicks (.008 in.; 0,20 mm) for inlet valves. One click is equal to .002 in. (0,050 mm). All exhaust and inlet valve clearance can be adjusted by positioning the flywheel only twice. After adjusting half of the valves, rotate the engine 360° in direction of normal rotation and adjust the remaining half. If No. 1 cylinder is in compression, adjust the inlet
