Tool for setting the injection angle Ursus C 360 C360

INJECTION ANGLE SETTING DEVICE URSUS C-360 C360 Can also be used for all tractors with M12 injection pipes

MAG: HAN00971

Capillary tube for setting the injection angle Technical data:

external diameter: 1.6 mm

internal diameter: 0.8 mm

capillary made 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 them freely engine crankshaft

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

set the fuel lever to maximum delivery

bleed air from the fuel system

turn the crankshaft several times until the fuel starts to flow out through the capillary tube

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

we slowly rotate the shaft 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 agree with the corresponding 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 be inserted into the hole drilled in the flywheel only if the injection start is correct.

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

- fuel delivery started after passing the marks 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 are for for adjusting the injection angle are made on the pump driving wheel).
