I welded the centre nut to the plate as trying to get a spanner in on a
3 bolt pull was a pain but on a 2 bolt it should be fine although I
could have threaded the plate instead, must have over-drilled the hole
by mistake.



By the way, did you still have to whack the centre bolt after
tightening it?


Last mowers I repaired would have been over 30 yeas ago now but I'd
suggest it's more of a controlled tap than a whack.

If the first tap doesn't do it a "little" more pressure on the puller
and another firmer tap rather than trying to grunt it off.

First thing to strip will be the threads in the flywheel holes but you
can always re-tap them to the next size up.

Worth noting that if tapping threads into a blind hole you need to start
with a tapered tap and finish off with a bottom/plug tap.
