Do you have to adjust the valve after adjusting the injector?
When applying the torque method adjustment, it should be noted that the valve of the same cylinder should be adjusted immediately after adjusting the injector of one cylinder, but it is not allowed to adjust the valve after adjusting the valve. 2.
How to adjust the height of the fuel injector?
Adjust the fuel injector height for the cylinder indicated on the chart in parentheses, see Figure “Timing Circle Chart” , by placing the small end of the height gage in the hole provided in the fuel injector body, with the flat of the gage toward the fuel injector plunger. See Figure “Fuel Injector Height Adjustment” .
How is intake valve clearance and injector height adjusted?
Likewise, injector height should be properly maintained. Intake valve clearance and injector height are adjusted by means of an adjusting set screw and locknut located at the valve (or injector) end of the rocker arm; see Figure “Valve and Fuel Injector Rocker Arm Assembly Components” .
How to adjust the valve lash and injector height?
Torque the locknut to 41-47 N·m (30-35 lb·ft) and remove the feeler gage. Reinsert the feeler gage to ensure that the adjustment did not change when the locknut was tightened. Readjust as necessary. For diesel applications the exhaust valves are adjusted the same way as the intake valves. See Table “Valve Clearance and Injector Height Settings” .
How to do an injector Adjustment on a Cummins?
The adjustment can begin on any valve set mark. In the following example, the adjustment will begin on the “A” valve set mark with cylinder number 1 valves closed and ready for adjustment. Rotate the accessory drive clockwiseuntil the “A” valve set mark on the accessory drive pulley is aligned with the pointer on the gear cover. Mark on pully
How is the injector and the valve interrelated?
The injector controls the fuel entering the cylinder. The valve controls the intake and exhaust valves of the engine. At the same time, the adjustment of the injector and the valve are interrelated in the adjustment sequence and method.
How to adjust engine injectors and valves sinocmp?
1. Torque method: The NT (A) 855 engine with a large cam non-stop injector is taken as an example to introduce the torque adjustment method. Look at Table 1 for the technical requirements for the adjustment of the injectors and valves of the NT (A) 855 engine.
How does the injector and valve work in a Cummins Engine?
The Cummins engine uses its unique PT fuel system. The injector controls the fuel entering the cylinder. The valve controls the intake and exhaust valves of the engine. At the same time, the adjustment of the injector and the valve are interrelated in the adjustment sequence and method.
