How is the idle speed (low idle) adjusted for engines equipped with an RSV regulator?

For engines with an RSV regulator, to adjust the idle speed (low idle): 1. Ensure the engine is at normal operating temperature. 2. Verify that the throttle control functions correctly and the injection pump throttle arm touches the low idle stop in the idle position. 3. Check that the air filter is not clogged. 4. Run the engine at idle and check the speed. If adjustment is needed, remove the dome nut and screw in or unscrew the adjustment screw (1). 5. If the speed oscillates, adjust stabilization by removing the dome nut (2), loosening the lock nut, and carefully turning the stabilization screw clockwise while monitoring the speed. Ensure the maximum speed (high idle) is not affected. 6. Lock the adjustment screw and re-screw the dome nut.

How is the maximum engine speed (high idle) adjusted for engines equipped with an RSV regulator?

For engines with an RSV regulator, to adjust the maximum engine speed (high idle): 1. Warm up the engine. 2. Run the engine unloaded at maximum speed and ensure the throttle arm touches the stop screw (3). 3. Check the speed with a tachometer. If necessary, adjust stop (3) to achieve the exact speed. The stop for maximum speed is sealed; the seal should only be broken by an authorized diesel workshop. After adjustment, the screw must be re-sealed with a legible authorization number.

How is the maximum engine speed (high idle) adjusted for engines equipped with an RQV regulator?

For engines with an RQV regulator, to adjust the maximum engine speed (high idle): 1. Run the engine at maximum speed for a brief moment, unloaded. 2. Verify that the maximum speed is within tolerances. 3. If necessary, adjust the speed using the stop screw for maximum speed (high idle) (2). The adjustment screw will need to be re-sealed after adjustment.
