The first time I removed Bumble's wheels it was a major effort and I had to resort to heating the
hex Octagonal
nuts to get them started. It's also quite difficult with the
hex Octagonal spanner on the left hand side as it's basically an overarm hit for a right hander, and the spanner is a loose fit. I put this down to enthusiastic tightening, because I've had no problems with the Roadster. However on the second occasion it was just the same, which puzzled me. I invested in the MWS brass spanner (as recommended by NigelP I think), and this has made it slightly easier, but still really needs a two handed hit with the Thor hammer. The reason that this job is harder on Bumble, even when the centres protrude further out and are more accessible can only be due to one reason - the black powder coating is grabbing the centre nut more effectively than the chrome on stainless of the Roadster.
So man logic and man maths have concluded that a solution has three ears. Or actually twelve ears.
This is the left hand part number:
I've also knocked up a wood and leather buffer although the wood may prove to be too soft over time.
A dab of yellow paint improves things:
I use Halfords touch up which has a thin metal tube in the cap - ideal for delivering a thin stream of paint.
White primer first then yellow.
The next step included hitting my thumb quite hard with the Thor, and using several innovative expletives............
But a good opportunity to clean the wheels, including the insides of course, which were quite grubby.
And now I reckon that the centre nuts will come off much easier, and with less damage to my thumbs. I may invest in a heavier Thor........................
