Mine is an XS firewall forward so I am not certain, but I
believe a starter motor out job on a classic f/f/w
requires engine out.

Adrian changed mine for me, in situ. I recommend him !

What I am nor sure of is whether the shaking is caused by
the worn sprag clutch or whether the worn sprag clutch has
been caused by the non-starting and kick-back.
The kick-back is caused by the starter just not being man
enough to do the job. (912S). Adrian put a HD starter on
for me and the engine starts instantly now.
If yours is a 912 then Peter Jeffers may help - he was
having similar problems and changed his sprag clutch at
around 1000 hours.
I understand that the HD starter motor will not fit inside
the classic engine mount. It is only a matter of 1/4 inch
or so. Maybe some judicious cutting and rewelding might
work (if approved !) or a large hammer ?
