I intend to change the Transmission oil of my 1988 Champion 720 Motor Grader, transmission model is 8400.
Despite not presenting any noticeable problems, I want to change the oil as the previous owner sometimes filled with ISO 68 hydraulic oil instead of Dexron II as indicated in the manual. I've only seen foam through the level gauge when it starts up.
Considering that the oil is contaminated, I intend to change as much as possible that is in the system, which according to the manual is 53 liters and I will put ATF 220 from Mobil, which is the oil with the Dexron II name available in these neighborhoods.
I would like to know if there is any procedure other than removing the drain plug and waiting for the last drop to fall and putting the new oil up to the middle of the level indicator.
Is it done with a hot or cold engine?
Is it necessary to prime the system before starting the engine?
I appreciate your advice.
