Information:
After the valve clearance on the valves for all cylinders has been adjusted, turn the crankshaft two or three times and make sure the valve clearance is correct.
Adjusting valve clearanceFUEL INJECTION TIMING
1. Preparation(1) Close the fuel filter valve.(2) Disconnect the No. 1 fuel injection pipe from the cylinder head and injection pump.(3) Remove No. 1 delivery valve holder from the injection pump. Remove the delivery valve and spring from the holder. Restore the delivery valve holder only to the injection pump.(4) Connect the fuel injection
