PROBLEM
Show/hide table
| The existing drive motor group may not operate as expected on certain two speed 236B3 Skid Steer Loaders. The machine may jerk to the left when shifting to two speed, requiring a joy stick correction in order to return to the intended path. This is due to an incorrect spool inside the right side motor resulting in motors not shifting at the same time. If machine has this problem, replace the right side drive motor group. |
