ADJUSTMENTS
Limiting device for injection pump delivery and torque gearing
device
It is housed in the pump control lever A and it is constituted of a
spring on cam B, limiting the stroke of the same lever A.
At the torque rate, the spring flexure, subject to the accelerator
control action, allows a further stroke of lever A, thus an increased
delivery of the injection pump.
Adjustment of injection pump delivery with braked engine
1) Bring the engine to its idling point .
2) Move the delivery limiting device 3 towards the left, see picture 88
3) Operate the engine until it reaches the power and rpm required
by the manufacturer of the equipment.
4) Make sure that the consumption is in compliance with the values
specified in the table of the adjustments (see information below).
If the consumption is in compliance with the fixed values, it is
essential to change the balance conditions measured on the brake,
operating either on the load and on the regulator.
When the engine is steady, carry out the consumption check again.
5) Move the limiting device 3 towards the right, as per picture 88,
until the engine rpm number descreases. Lock the limiting device
by means of the two screws.
6) Completely release the brake and check the rpm at which the
engine settles. The speed governor performances shall be in
compliance with the class required by the manufacturer of the
equipment.
7) Stop the engine.
8) When the engine is cold, check the valve clearance again.
