Replacing front crank shaft seal TB42

[Parksy]

Just looked under my tb42e and it looks like the front seal is leaking. Once the harmonic balancer is off, is the seal easily accessible? Just remove old one and insert new one?

Edit: never mind found some pictures, just pry old one out and gently press new one on evenly.
Is the crank bolt a typical lefty loose to undo?

I have used the crank the starter technique a couple of times to undo the crank bolt. - I didn't like it the first time but I had tried all the other metdos .

The only other way is to make a wedge that can be used on the fly wheel teeth.
