Device for setting the injection angle ANDORIA - MOT ANDORIA-MOT

Capillary tube for setting the injection angle Technical data:

*outer diameter: 1.6mm

*inner diameter: 0.8mm

*capillary made of glass

⚠️When installing a new or repaired injection pump, set the injection start angle ⚠️the proper fuel injection start angle and the method of measuring it are always given in the engine manual Instructions for setting the injection angle:

-turn on the depressurizer or unscrew the injectors to be able to rotate the engine crankshaft freely

-place the tube of the first cylinder with a capillary (a device for setting the injection angle)

-set the fuel lever to maximum feeding -bleed the fuel system

-rotate the crankshaft several times until the fuel starts flowing out through the capillary tube

-set the engine so that there is a compression stroke in the first cylinder (both valves closed)

-turn the shaft slowly to catch the moment when the fuel in the capillary begins to rise (this can be easily noticed because there are always small air bubbles in the tube)

⚠️the moment of the observed start of fuel pumping should match the appropriate mark on the flywheel. In the Ursus C-330 tractor, instead of a sign, there is a special pin located on the right side of the flywheel housing. This pin can only be inserted into the hole drilled in the flywheel if the injection start is correct.

⚠️if the fuel supply started earlier than indicated by the signs, it means that the injection start angle is too large

⚠️fuel injection starting after passing the signs indicates that fuel injection is delayed

⚠️In order to delay the injection with the flange mounting of the pump, turn the pump in the elongated holes in the direction of rotation of the drive shaft, turn the pump in the opposite direction to increase the injection angle (in the Ursus C-330 tractor engine, the elongated holes for adjusting the injection angle are made are on the wheel driving the pump)
