its easy, just remove the flywheel - theres a special tool you can use to drwa the primary gear out - which removes the seal - then another special tool to press the seal back in.
you can 'flick' the seal out with a screwdriver, but you will need the tool to fit the seal with no worry of it leaking.
you will also need a special tool to remove the flywheel

Quite right, as always, Richy.
I always just dig the old seal out with a thin screwdriver, but I do have the correct tool - that's the 'top-hat' tool to push the seal home nice and square and the protection sleeve to guard the lip of the seal whilst it passes over the primary gear splines. In fact, it an be done without any special loating tools and using masking tape wound around the splines, but it's easy to get it out of square and then it can damage the new seal.

The pullers are rarer than hens teethI always just dig the old seal out with a thin screwdriver, but I do have the correct tool - that's the 'top-hat' tool to push the seal home nice and square and the protection sleeve to guard the lip of the seal whilst it passes over the primary gear splines.

But would definitely recommend the insertion tool.

thats the 'putter - inner'the 'puller - outer' is a sykes tool that turns up on ebay.
that and the awsome hydraulic flywheel puller ive just bought makes doing stuff like this an actual pleasure!

I could be wrong but , don't the early flywheel housings have a flange behind the seal which prevents the gear being pulled out like the later ones, I'm sure i've come across this and thought what a dumb idea
your right rich, but i think the primary gear will pass though?, the lip just lets the oil seal locate in the right place.will look into it and let you know!

No the primary gear needs to be in place when you fit the seal.AND DOES ANYBODY HAVE A FLYWHEEL OIL SEAL FITTING TOOL THEY WANT TO SELL

The fitting tool I listed above, the puller is no longer made and are as rare as hen's teeth, expect to pay over £100 for one, if you can find one.
Try your local mini club, someone may have one you could borrow.
You can change the seal without either the removal or re-fitting tool. It's just a lot easier if you have the right tools for the job.
I've never had a seal removal tool and never had any problems getting the old ones out. I used to use a 6" long piece of pipe the same diameter as the outside diameter of the seal for re-fitting and masking tape coated in light grease to protect the lip of the seal when sliding it over the primary gear splines and over the lip onto the primary gear plain section after the splines. Then just held the tube against the seal and gently tapped it until it was in the correct position.
It is easier with the top-hat tool though. I thought Mini Spares sold them (Richy?).
