Personal injury can result from hot oil or hot components. At operating temperature, oil is hot and under pressure. Hot oil can cause burns. Remove the fill cap only when the engine is stopped, and the fill cap is cool enough to touch with your bare hand. Do not allow hot oil or components to contact skin. |

Note: Put identification marks on all lines, on all hoses, on all wires and on all tubes for installation purposes. Plug all lines, all hoses and all tubes. This will help prevent fluid loss and this will help to prevent contaminants from entering the system.
Note: The transmission hydraulic control valve can be removed with the cab on the machine. This process will be easier if the cab is removed. For photographic purposes, the cab has been removed.
