Thanks to all for the speedy replies!
A quick check using an unmarked "Monkey wrench" and a ruler confirms 36mm - ish.
Thanks Wagtail and K5lwq for the tips.
Finding a helpful community is as invaluable as having a Service Manual.
Thanks from Canada, eh!
Could anyone please tell me what size socket is required to remove the drive pulley from the crankshaft?
I have the Service Manual, but it does not specify any bolt head / nut sizes.
Thanks in advance,
Mike.
