Right Angle Gearbox

Right Angle Gearbox Rebuild

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.
