Odd Bearing Retainer (Front Wheel)

[Raygun]

1977 CB550 F

I was under the impression the front wheel bearing retainer had only 4 notches, though this one seems to have a few more?!

Does anyone know what tool is required to remove this as the standard CB500 Front Wheel Bearing Retainer tool doesn't look like it's the right one

The slots appear to still be opposite each other though - I used a piece of 25mm wide x the slot thickness bar (x the bearing retainer diameter for the length) with a slot filed in it to clear the spindle end. I then put an adjustable spanner/wrench on it as the lever to turn the retainer. May need to use a punch to get it started

Looks home made and i think i can see half a hole on the hub where an original staking has been drilled out, try some heat to loosen the crud
