Question sir good day i woul to ask about how to adjust the valve and injectors of n14 cummins thanks
Answer The basic rule is to check the engine data plate for information on the type of injector adjustment as well as the valve inlet and exhaust valve lash values.
Generally, the following steps are instructive:
1. Confirm injector travel and valve lash values for the engine you want to set.
2. Confirm the timing pointer on the front gear housing and the timing marks on the accessory drive pulley. There is A. 1-6vs; B. 2-5vs; and C. 3-4vs.
3. Turn the engine in the dorection of rotation until a timing mark aligns with the timing pointer. Check the valves on the 2 cylinders under reference and confirm the one with both intake and exhaust valves closed. You will set the valves on this cylinder. select the appropriate feeler gauge and adjust. It is better to use a 6in. torquemeter to ensure evenness. lock the locknut to 35lb-ft torque.
4.Depending on the injector type, you will adjust the injector either on the same cylinder or another cylinder as may be specified by the manufacturer. Torque the capscrews locknut to 35lb ft ensuring that the capscrew does not change from the set position.
5. Move on by turning the engine in the direction of rotation to the next timing mark.
