Recently took apart the Bobcat soil conditioner I have. I bought it used from the rental fleet at a nearby bobcat dealer. What I found was very disturbing. The female spline (10 tooth) was stripped. I now know why the drum stopped rotating! The obvious fix is to replace the female spline part which is of one peice construction and is connected to a square tube that drives the drum at a cost of $1000USD +. Any thoughts or comments? I was thinking if I could find a female 10 tooth spline someplace I could drill out the old and weld in the new.. I'm looking for a machinists perspective who may have encountered same problem. Help please!
