ACTION REQUIRED

Show/hide table

Attention: Before beginning any of the following work, place the machine in a safe state. Ensure that you have read and understand the Operation and Maintenance Manual for safety information and safe working practices before starting this Rework Procedure.

It is our recommendation at this time, based on the data that is currently available to us, that a flush-and-refill procedure will be adequate to mitigate the negative effects of the FDAO.

1.) Drain the axle and remove the center drain assembly (eco-drain). This drain assembly should be removed, not just opened.
2.) Remove both final drive drain plugs.
3.) Remove and replace the Diff Lock oil filter.
4.) Replace the drain plugs and fill axle with TDTO-50
5.) Drive machine, making some turns so that differentiation occurs.
6.) Turn on diff lock for one minute.
7.) Drain oil as outlined in steps 1-2.
8.) Remove and replace the Diff Lock oil filter.
9.) Replace drain plugs and refill with TDTO-50
