Thanks Bert. That sounds ok for those with experience but do you think it would be safer for me to use a puller? Less likely to have a mishap?
Thanks
Believe it or not, pullers make a bigger mess than smacking it with a hammer because it is on a taper.
If it was a parallel shaft like an axel then a puller is good but on a taper, a short sharp shock is the way to go.
The only catch is you must protect the thread which is why you put the nut / bolt back in loose by 1 turn.
SHMBO is 5' and weighs almost nothing wringing wet so she uses a really long wrecking bar and sits on it with her legs either side of the engine then applies the blow.
Some call them crow bars you know the jobbie a bar with a hook at one end and a bend at the other.
The bent bit goes on the fins with the end under the flywheel.
Pullers usually mash up the end of the shaft and rip the threads out before the flywheel even looks like budging if they don't actually break themselves.
The holes for the puller are not tapped so before you start you need to thread the holes then get the correct puller.
And when you get that you will still have to smack the puller with a hammer because with a taper, the puller is not a puller but a preloader so when you hit it with a hammer the shock will break the lock of the taper.
A jaw puller on an alloy flywheel will cause the flywheel to bend and in bending lock the taper tighter.
