I didnt make it to the show, so was unable to see any demonstration of the checking tool, so perhaps what i am asking has already been sorted.
I was just wondering can someone tell me what the datum point is?
In other words does the tool hold the crank at TDC, and so the coil position should then register on the magnet at the position photographed in the tech regs, which is very vague, or is it something different, e.g. it holds the crank at the correct advance, and the indicates to a different mark on the flywheel.
My concern is the tool holds the crank, on the clutch side, and aligns its self on the woodruff key (as i understand the tool so far), an area which does wear through use of the clutch. This section of the crank is a very small diameter 19mm, and then taking a reading from the flywheel at 170mm diameter, could lead to incorrect readings.
If the scrutineer tightens the tool just 4 thou out of true, (which is perhaps the amount needed to make it push fit anyway) or the tool wears through use, that will i think mean a full degree difference on the circumference of the flywheel. Also if the crank is hot, the tool will have to be opened up to fit on etc????
I like the idea of getting the timing figures equal and i really want the checking system to work, it just bothers me that the tool will work when brand new, but will not be as precise the more engines that are checked, lets face it not all scrutineers are mechanics or engine builders and so not all will have the understanding of how it works and what is they are actually checking.
Hoping to be corrected
