ENGINE 75 Fig. 1 Fig. 2 ADJUSTMENT OF VALVE CLEARANCE (Cylinder head cover removed, Temperature: cold or cooling system at maximum 50 deg C) 1 Adjust valve clearance in compression TDC and in firing order of individual cylinders. Firing order is 1-3-4-2, beginning with first cylinder (starting at radiator). Fig. 1. Compression TDC is recognized by the overlapping valves of counter-cylinder (counter- cylinders are 1 and 4 or 2 and 3). EXAMPLE With valves of 4th cylinder in overlapping position, valves of 1st cylinder can be adjusted or checked. TURN ENGINE IN DIRECTION OF ROTATION ONLY. 2 For measuring and adjusting valve clearance, insert pertinent feeler gauge between valve stem and rocker arm. Valve clearance is correctly adjusted, if feeler gauge can be pulled through under slight resistance. 3 If a correction of valve clearance is required, loosen lock nut of ball-head screw. Adjust clearance by applying screw driver to ball head screw. Tighten lock nut. Adjust ball head screw in such manner that feeler gauge can still be moved smoothly with lock nut tightened again. Fig. 2. 4 Alternatively, valve clearance can be adjusted by turning crankshaft only twice as follows: a. Turn crankshaft to bring No. 1 piston at TDC (compression stroke). To ensure this position remove clutch housing inspection cover and turn crankshaft to coincide TDC (red) marking on flywheel/ring gear with pointer on crankcase. b. Adjust valve clearance of valve numbers 1, 2, 3 and 5 starting from front end. c. Turn crankshaft by 360 deg (in direction of rotation) so as to bring piston No. 4 at TDC (compression stroke). d. Adjust valve clearance of valve numbers 1,2,3 and 5 starting from rear end (or 4, 6, 7 and 8 from front end). e. Refit clutch housing inspection cover, if removed.
