[QUOTE="brunsyeah, post: 12477, member: 1421"] I think I have it figured out! I pulled the flywheel and lifted the cab to figure out what I could. I got the motor mounts today from local bobcat dealer and had them print off the expanded parts diagram to figure out whats missing! Start with my assumption about what happened, they removed the engine from the bobcat, but in the process decided not to remove the pump, so essentially everything connecting the two has something wrong with it! Damages so far: 2 rear motor mounts missing one of the top bolts that connect the motor to the flywheel housing (which is called the Mount #29 on the parts diagram) is missing. These are diagram number 27 (pn# 5cm1025)there are three across the top. The two bottom bolts that connect the motor to the flywheel housing (Mount) are missing. These are diagram number 31 (pn# 12cm1230) The bolt attaching the hydraulic pump to the front left motor mount is missing, Diagram number 9 (pn# 17c840) So that is where I stand! None of these instock at local dealer so it will be late in the week before I get back to it.... So here is what happened in my opinion. I know the motors been replaced, they put the motor back in, didn't install all the bolts, but it was lined up good enough at the time to start the engine and drive, as they drove the two vibrated away from each other, the starter then began barely touching the ring gear, this destroyed the original ring gear. they thought oh thats the problem so they replaced the ring gear, they put a new one on, but it was backwards! Anyway that wouldn't fix the problem as the starter no longer touched the ring gear! Solution: Pull the pump and flywheel housing forward, replace the front left bolt and tighten the front right motor mount back into place (it is also out of its mount as it just slides in and out!). Then pull the motor backwards to align the motor to flywheel housing mounts and hook those back up. Big finish with actually installing rear motor mounts! [/QUOTE]
