Hi Drikko,
(If I remember right ....

)
The rebated external spacer (#17) should come out easy enuf. When clean, it's a sliding fit, so it's now just playing with you

. Be firm but nice (easing oil and heat), and it will yield ('he says ....'

)
After that, blind puller for the first bearing, #4 - an expanding frame anchor/bolt of the right size normally does that job ...
(admin edit: image posted deleted by admin after receiving a warning message regarding use)
If not, get a proper puller
After that the internal spacer #15 falls out and you can tap - NO BASHING!!

- the other bearing out from the inside.
HTH
