Adjusting Valve Clearance and Injector Stroke for Cummins NT855 Engine
Valve Clearance Adjustment
The specified valve clearances for the Cummins NT855 engine are as follows:
- Intake: 0.28 mm
- Exhaust: 0.58 mm
To adjust the valve clearance, use the feeler gauge provided in the Cummins designated toolset. The adjustment process involves the following steps:
1. **Top Dead Center (TDC) Alignment**:
- Rotate the crankshaft to align the timing mark at point A, ensuring that it corresponds to the TDC position of the compression stroke for cylinder 2.
- Confirm that cylinder 2 is at TDC by checking the position of its valves. Once confirmed, adjust the valve clearances for cylinder 2 using the 0 clearance method. This means adjusting the next cylinder (cylinder 4) immediately after completing the adjustments for cylinder 2.
2. **Adjustment Sequence**:
- After rotating the crankshaft 360 degrees, with the timing mark still at point A, adjust the valves for cylinder 2 and the fuel injector for cylinder 4. If the fuel injection timing is incorrect, rotate the engine another 360 degrees to ensure proper alignment.
- At point B, adjust the valves for cylinder 4 and the fuel injector for cylinder 1.
- At point C, adjust the valves for cylinder 1 and the fuel injector for cylinder 5.
Important Notes on Valve Adjustment
- Valve clearance can only be adjusted when the valves are fully closed. Ensure that the rocker arm rests on the base circle of the camshaft before making any adjustments.
- Do not adjust intake valves that are currently in the intake stroke, about to start the intake stroke, or have just completed the exhaust stroke.
Injector Adjustment
The fuel injectors of the Cummins NT855 engine are self-adjusting and do not require manual adjustment. However, if you need to verify or inspect the injectors, follow the manufacturer's guidelines for inspection procedures.
Specific Steps for Valve Clearance Adjustment
1. Loosen the locknut on the valve stem screw using a wrench.
2. Insert the appropriate feeler gauge between the rocker arm and the valve stem.
3. Adjust the valve stem screw until the feeler gauge fits snugly but can still be moved slightly.
4. Tighten the locknut while maintaining the correct clearance.
5. Recheck the clearance to ensure accuracy.
