2. INSPECTION AND ADJUSTMENT In case of 3-cylinder engines, turn the crankshaft 240° and make adjustment for the No.3 cylinder. Then adjust the No.2 cylinder in this order. The cylinder to be adjusted first does not have to be the No.1 cylinder. Select and adjust the cylin- der where the piston is the nearest to the top dead center after turning, and make adjustment for other cylinders in the order of ignition by turning the crankshaft 240° each time. The adjustment method of reducing the flywheel turning numbers (for reference): For 3 cylinder engines Set No.1 cylinder to the compression T.D.C.and adjust the clearance of the q mark of the below table.
Next, turn the flywheel once (the suction / exhaust valve of No.1 cylinder is in the position of the overlap T.D.C. at this time), and adjust the clearance of the Q mark. Ignition order of 3 cylinder engines: 1 o 3 o 2 The first time The second time For 4 cylinder engines Set No.1 cylinder to the compression T.D.C. and adjust the clearance of the q mark of the bottom table. Next, turn the flywheel once, and adjust the clearance of the Q mark. Ignition order of 3 cylinder engines:
1 o 3 o 4 o 2 The first time The second time (b) Valve clearance inspection and adjustment 1) Loosen adjusting bolts In case of 2-valve cylinder head loosen the lock nut and adjusting screw, and check the valve for any inclination of valve cap, entrance of dirt or wear. In case of 4-valve cylinder head loosen the lock nut and adjusting screw of rocker arm. Be careful that excessive tension isn't applied to the cross head, and loosen a locknut of cross head. [NOTICE] When loosening a locknut of a cross head, loosen the locknut while fixing the cross head with a wrench so that the valve may not lean. 82E-5 – 98E-5 SERIES 2-21 Cylinder No.
