Description of Change: A new piston pump group replaced the former piston pump in the hydrostatic drive system. The new pump group has a stronger, crack resistant head.

Adaptable To: The new 133-1333 Piston Pump Group is a direct replacement for former 111-0371 Piston Pump Group. The new piston pump group is effective with the 914G (7ZM211, 9WM330) Wheel Loaders and IT14G (8ZM186, 1WN236) Integrated Toolcarriers.
