Thomas & Bill,
My sentiments exactly! however in this case it worked out a bloody odd size
in metric and I WAS using calipers ( in metric).
Now I grew-up with Imperial and still use it ( as well as metric) but Thomas
is correct in that this is a motor built in the metric system and we should
therefore use metric - all MY drawings are in metric, but even then there
are some odd seizings floating around, I can tell you!
You only have to look at the timing wheel to see that, and I can tell you I
like ( and look for) full millimetre sizes, but sometimes it just ain't the
case.
Don't ask me why!
