PROBLEM

Show/hide table

The existing yoke on the 419-2892 Transmission (2 speed) can fail on certain 553C/563C/573C/2470C/2570C/2670C Wheel Feller Bunchers, and 586C-2864C Site Prep Tractors. If the leak is a result of yoke to oil seal interaction wearing a groove in the yoke shaft, it can result in oil loss from the (2 speed) transmission.
