Nice to meet everybody, finally, through an active post.
Does anybody have any idea what this is? I have a feeling that it might be an automatic advance device for the injection pump
timing, but I am not sure.
is a chinese diesel
, Yangdong, I think YSAD 380, and I cannot really find too much information on it. Or the information is not very clear... I guess lack of information comes with the price
for these engines.
The device is attached to the injection pump
. The 2 halves can slide apart during engine
rotation proportional with the speed and spin the 2 eccentric circular things underneath them. The device is not present in the engine schematics I have. Those only have the injection pump gear
The question arise as according to the manual, to adjust the injection timing, I should have 3 screws in elongated holes on the injection pump gear face, loosen those and turn the timing gear to get the desired values.
I only dismantle things to where they were in the last picture. Undoing the center bolt did not seem to loosen the part covering the actual gear.
Pictures are rotated 90 degrees counterclockwise...
