Ok so removed damaged hydrostatic final drive motor and replaced with reman final drive from CRC Components….got the reman re installed, all lines were labeled and landed onto the correct connections….i go to start the machine, turn the park brake off, and slowly engage the drive lever forward and reverse, the drive sprocket will rotate about 3-4 inches and then lock up and bogs down like the park break is set
The other side moves OK? If so, sounds like an issue with the new drive motor. You didn't by mistake leave any plastic caps on any of the lines?
This may sound foolish, but it might be worth double checking to make sure all the hoses are connected. leaving the brake line disconnected could give similar symptoms.
