PROBLEM
Show/hide table
The existing elbow on the head end of the lift cylinder can contact the inside surface of the outer tower plate on certain 236B2 and 236B3 Skid Steer Loaders. If the existing elbow contacts the inside surface of the outer tower plate, it can lead to possible cracking of the elbow resulting in a hydraulic leak.
In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 7% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
