Gearbox oil change

Thanks DW,
I hadn't thought of diesel, I will give that a go.

from Marty.

Same as DW, had the same thing in an old ford tractor we bought. Sump plug (engine)had been rounded off, oil looked like it hadnt been changed in years. Managed to get it off. Cleaned out with diesel. Worked fine

Top advice that.......

Yep, this is how I'd do it....

Same as with engines, always drain oil while it is hot, and pull the bung as soon as possible after a good work-out (within seconds, not minutes after engine shut-down), for the reasons already stated..


:)

Damn, what a fantastic thread.

Explore Oz by tractor!

Thanks guys ;-}

actually if you look into it a convoy of Chamberlain tractors did a trip around Australia, old ones at that, was a fantastic idea and was an eye opener, we came accross them at Kunnanurra ............... top blokes i may add.. and after all, what is the hurry i ask ???
What a way to see Australia.....

This may be a little more help if you like..
Do the diesel thing (its a top idea actually...have done it more times than I can remember)..BUT...add about 2 litres of auto transmission oil to the diesel.
Dont fill it right up...just to normal levels. Then take tractor for a slow drive on good flat ground for about 2 minutes....both forward and reverse. Dont place any load on it ...all you need to do is give everything a good spin and whirl around...have engine running at aboout 1000-1200 revs.Then drain it all out overnight. refill with an ordinary basic cheaper engine oil ...and drive it about as before...but for 5 minutes this time...drain oil overnight again. the engine oil will flush out the diesel mix, but the small amount that is left wont affect the correct oil in any way. It is not really expensive in the scheme of things (I used supermarket engine oil)...and it works well.
In a previous life I was a western Cocky...and we had 2 Chamberlains...a C670 and a C6100...both of which did huge hours. we did this process to each of them every 5000 hours....and neither tractor had any drivetrain problems wotsoever. normal oil changes were done every 2500 hours (I think)
BTW...do the slow drive in the normal working gears..IE...not high range.

HTH.

Cheers Keith

P/S..90 grade gear oil for main gearbox and rear gearbox/diff...but 140 grade for final drive reduction...worked for me.
