starter gears are not normal gears, they are too small for their tooth
count. Also most starter gears are the same inch/metric, IOW the metric
ones are identical to much older inch series. IIRC the vw uses a 1 inch
diameter, 9 tooth pinion. This is a wide standard used everywhere. You
can also use an 11 tooth 1.15 inch diameter if you offset correctly. YOu
will more than make up for the slight mechanical disadvantage with the
better tooth form.
Grab such a pinion from a electical rebuilder and measure the two
together engaged, do the math, add ten thou and be done with it. It
isn't that fussy






Thanks, this is exactly the info I was looking for. My measurements of
the starter pinion match yours exactly.
