VFR800X Rear Hub Bearing Holder Removal - it wont budge!

[Skids]

Looking for some suggestions.
 
I'm trying to remove the rear hub bearing holder on my '15 VFR800X so I can inspect the mating surface on the eccentric cam as it is getting increasingly difficult to tighten the chain. I've un-staked the 46mm axle nut but cannot get it to undo. I've tried with my breaker bar and a hollow pipe extension fed over it, so about 3-4ft of leverage and it simply wont budge. I've applied some WD40 where I can and will wait now until tomorrow to see if it ingresses at all but after that, I'm stuck as to what to do.

Any suggestions?

Heat it up not ideal you will need caution, buy a new nut and grind through the old one part way and split it with a chisel, sometimes tightening first can help.

There are more effective penetrating oils out there than WD40.  PlusGas is excellent as is the 3in1 equivalent.
Let us know how you resolve this.  I have probably got this lying in wait for me as I so rarely have to adjust the chain (Scottoiler), that mine is almost certainly solid too.

Managed to loosen the adjuster by prising open ever so slightly the bearing holder clamp and sprayed some WD40 in the gap then worked the chain adjuster sprayed a bit more etc until it did loosen off quite well.

I'll take that as a partial win for now.

Well done.  Stuff that is supposed to move and doesn't is a right PITA.  I'm in the process of sorting a Defender TD5 with my son, and this is a frequent and frustrating issue.

I didn't realise TD5's had a SSSA.

I’ve used a product called Shock Unlock on stubborn stuff in the past. It’s a freeze spray and penetrating oil combined.
The cold causes cracks in the corrosion that’s holding everything together and as it returns to normal temp it draws the penetrating oil into the join.
It released a completely seized mirror stalk adjuster that hadn’t moved in 10 years. Took some doing and a number of reapplications. But it worked.
