This time around I tore into the right angle worm gearbox for our King kiddie ride rebuild. This gearbox has a ratio of 9.66. In combination with the chain sprocket, this results in a final speed of about 10 RPM.
Completely disassembled the gearbox, gave it a bath, and replaced all the Timken bearings and seals. We also replaced the belt pulley and hub as the originals were destroyed trying to get them apart.
Abart Gear & Machine Co from Chicago Ill. manufactured this worm gearbox / speed reducer
- Type 26-U

According to the web, Cleveland Gear company acquired Abart in the 1980's
