I have a 30SCTT. left drive wheel is locked up tight. A tech on this forum said it is most likely the bearing. Right wheel spins freely when the forklift is blocked up. It appears that there are three very large bolts holdind the drive assy to the frame and 4 bolts go through it to hold the motor on to it. Can anyone give me some idea on how to get this off and access the drive bearing? Thanks much.
