K3M injector timing

[ecoke01]

I have just installed a new injector pump on my cub cadet 7273 tractor.
runs great now as long as there is no great load on the pto.
I notice if my finish mower gets into high grass and it starts to drop rpm there is knocking clanking sound
that seems to be centered near the engine fly wheel area.

so I am thinking the injector timing needs to be set. (assuming the torque curve is not at specs.)
I got a K3 engine manual and the timing setting is simple.
But NO timing Marks on the front pulley as shown in he manual.
Boy that I s a kick in the butt.
I need 19 degrees before TDC. there is supposed to be a mark of three lines which is the timing mark for setting the injector timing.
loosen the number one injector line at the injector nozzle, turn the engine clockwise until fuel is just seen to appear, and you are at the point where the injector timing mark is supposed to
line up with the stationary mark on the timing cover.

looking for bright ideas.

updating my own post.
the problem was not so much with the injector timing. The bush hog ran fine on this tractor. I thought it was because of the heavy blades giving no stalling with their
mass and velocity. One small problem was a slightly loose idler pulley on the finish mower, but the real problem was the old belt had stretched and was not allowing the power transfer to the blades. The blades were slipping when they hit any tall grass resistance. Now the finish mower cuts like IT was the bush hog..
I still want to figure out how to properly measure the injector timing without marks on the crankshaft pulley.

I will solve it and share.

thanks

I would like others to correct me on this one !
First is to get TDC and mark it.
Then messure the diameter of the front pulley and calculate the circumferens
Then by using maths you calculate the lenth for 1 degre x 19 and mark that distans from TDC on the pulley as 19BTDC
Now to get no 1 firing on your inj pump .
Make sure that inj and 19BTDC is wright
