Changing V6 Fan Bearing

Hi all, was wondering if anyone is familiar with the best way of changing this bearing. Haynes manual says to use a press to remove the old one and insert the new one. I have also read where a little heat can be used to heat up the alloy cover to drop out the old one and insert the new one. There is also the hub to take off the old bearing and fit on the new one. Any advice greatly appreciated.

The replacement bearings available need a trimming down of the shaft as they are longer

Hey Guys, I'm a new member looking for a restoration project, had a Mk1 1970 back in the late 70's early 80's....
I also have spent my entire working life in the bearing industry BTW, it been a real long time since I changed out that fan bearing, I have a distant memory that , the bearing had a wire clip  or circlip, that needed to be extracted first , 
my books tell me the ford number was 2720E8626A, the RHP No. ( the actual manufacturer) was (  or should be !) FPS396, Which I doubt very much you will find, there was a "soft shaft" universal version available, where the bearing inner race ( which is the shaft) is only hardened on the ball track, hence you can cut / trim the excess, much better to get a machinist to do,
if you cant find one, sing out and i'll see if i can round one up for you - but I'm in Perth
Cheers
