I recently bought a hub motor MAC 6 T , then bought a Sunrace MFEX9 9 speed freewheel,
I did not have a freewheel remover tool, so I put the freewheel on hand tight, but noticed it needed a little more torque,
so I got my chain whip tool ( sprocket Remover Tool ) and tightened (clockwise ) the freewheel on a little more
after that I tried to turn the freewheel ... counterclockwise, to see it working but it does not turn counterclockwise, ?
I looked to check the spacing between the freewheel and the hub, and there is plenty, 4-5 mm no issues there.
Hub not laced up to a rim yet so no issue there either .
What is going on ?
So then I went to a couple of bike shops to find a freewheel remover tool, and bought one, ( Park Tool FR-1.2 for Sunrace/Shimano/Sacs )
got it home only to find out that the hole in the middle of the remover tool is too small for the axle of a electric hub motor .
they are made for axles that are up to 10 mm O.D. and the MAC electric hub motor axle is 14mm O.D.
I will try to drill the hole bigger , although I called Park Tool and they say the tool is hardened steel, so have not done that yet.
I put in a request to the tec worker at Park Tool and he said that the company does know about this problem, they just don't make a freewheel remover tool for the larger axle's , yet. Who Does ?
