Timming a 951 di
I'm trying to time the crank to the counterbalance shaft. The manual says to alighn the timming marks on the gears. But my gears have no notch only a blue paint mark. Do i go by that.
Some one please help if you can. I got this motor all apart.
I can see in the manual how to set the crank in the block with the notch alighned with the case. On the large couterweight.
Thanks if anyone thet can help. Rich

Yes the blue marks for alignment or look at the way the counterweights are and they should be facing away from each other.

Can you shoot us a pic? Sometimes the casting indicator marks are so rough they are hard to make out.

I just checked all the CB shafts i have on my bench, and they all have a blue mark for alignment.

that link doesn't do squat for timing a 951, it talks more about adjusting an already running engine for performance via timing changes........
the other advise with timings marks on c/b & crank is your answer

dont trust any marks idi once - once!
spin the crank so that the mag bigend pin centre is aligned with the flat (mating) surface of the cases, then put in the balance shaft so that the counter weight center on the mag side is facing the crank big end pin and is centered to the flat mating surface (thats the centre of the heavy side) it will also be the reverse on the pto.
so two will face eachother and the other two will be apart
