[QUOTE="campbell45, post: 129389, member: 23825"] Hi guys, hope someone can help me. I recently bought a used bobcat 731 for pretty cheap. Runs and drives but soon after running the right side would not want to move. I assumed it was the hydrostatic drive pump instead of the motors. I have sent the hydrostatic drive pump to be rebuilt and decided to pull both drive motors to put a new seal kit in and inspect them for wear. The left side (which let the machine move easily) looked original and so I tore that down first. Afterwards, I tore the right side down (which was the side that did not want to move). I discovered a few differences in this pump compared to the left side. See the attached picture. As you can see the right side has more of an oval shape at the bottom where the o-ring sits compared to the left which is a complete circle. I'm now worried someone replaced my right side with an incorrect drive motor. Or possibly this is a revised version of the original drive motor? Can anyone help me identify this? Both motors are missing the riveted ID tag. [ATTACH type="full" alt="drive motors.jpg"]4699[/ATTACH] [/QUOTE]
