Slide gearbox

A member (gomatthew) is sending me 2 broken gearboxes that I will be reworking and I will submit my new design changes to the manufacturer..

I will make a bracket with the double sprocket tied to ia separate shaft and then coupled to the motor shaft , so if the motor or gearbox ever needs replacing, it should be a 10 minute job. It is insane that it is set up so you need to loosen all the cables to change out the gearbox.

Good Luck!


If they adopt the changes, I hope you get paid for them!

I may be more interested in selling the adapter plate and supplying modified gearboxes

I received 2 old gearboxes today from member (gomatthew) to study changes needed.
I worked up the drawing for an adapter plate (about 4" X 7") to hold the sprocket in place.
If the gearbox ever goes bad, you will only need to loosen a set screw on a coupling that connects the sprocket shaft to the gearbox shaft.
Then slip the gearbox shaft out of the coupling. No need to loosen cables, chains etc.

A gearbox swap out should take less than 10-20 minutes. As long as you have removed the wood panel covering the motor / gearbox.

Since the gearboxes are supplied with sprockets, you would also need to remove the sprocket on the new gearbox.

All parts are now on order. I hope to have an assembly made up by the end of next week. If so, I will post a picture.

The design has come together and I feel it will be a relatively quick and easy changeover. (The cables will need to be marked with white out to mark their current settings first, then pull out the original bracket and install my bracket)

Once the changeover is made, replacing a dead gearbox in the future will be simple.
