440 Skidoo clutch removal?

[440ROTAX]

I need some info on pulling the whole clutch off a 440 Skidoo Rotax motor ? It has the square shaft end type.
And the square shaft end is messed up bad!
So it rattles like Hell!
So the clutch back half closest to the motor Has to come off the end of the crank.
Off any ideas how this is on there?Is it Pressed on or threaded on the end of the crank?

Thanks Ross

I had a 377 Rotax motor in a safari it had
a square clutch shaft too and I
Tried everything to get the clutch off with no luck!
Then I found out u need a long bolt type puller for that motor!?
So what I'm sayjng is this it sounds like the clutch from the safari is the same as yours u may need bolt type puller
