Bengal disc brakes pulley sealing plug for KMX trike
by sanktnelson, published
One of a bunch of improvements I made for my KMX Cobra recumbent trike: Since several of the pulley openings point upwards, they collect dirt and water, eventually leading to corrosion of the pulleys or just freezing in the winter. This thing is intended to seal the end at the brakes a bit better.
print, maybe drill out the hole, squish into brake pulley hole as shown in the picture, then feed the pulley through. Maybe press some grease into thespace under the plug for some extra water resistance.
The hole is significantly bigger in the design than is neccessary for the normal pulley diameter, but my printer tends to shrink small holes, so it fits perfectly for me. Openscad source provided, so change as you like.
