How to Adjust Kubota Engine Valves?
1 Answers
Based on the cylinder firing order, after determining that a certain cylinder's piston is at the top dead center of compression, the intake and exhaust valve clearances of that cylinder can be adjusted. Rotate the crankshaft to position the first cylinder's piston at the top dead center of compression, aligning the flywheel mark with the inspection hole line. At this point, valves 1, 2, 4, 5, 8, and 9 can be adjusted. Rotate the crankshaft one full turn to position the sixth cylinder's piston at the top dead center of the compression stroke, then adjust valves 3, 6, 7, 10, plus two additional valves (i.e., 11 and 12).
