ohh my god that's disgusting!!!!!!!!!!!!

first thought upon cracking the seal to the gear box.

Can anyone suggest a good method for flushing the gear box?

I am in the process of rebuilding motor and unfortunately need the old girl back at work asap so am trying to do as much as possible quickly and the condition of the oil that came out of that box @@@@****?????. Milkshake

Is diesel a bad thing ?

Was thinking of something to poor through to try and loosen some scum and give an extra couple years.
What works and does not require the specialist equipment i have read about.

Sounds savage but am almost thinking to fill the whole thing with degrease and water for 12 hours flush out with oil/diesel and then fill ready for use? I don't like the sound of it myself but opinions please.

Diesel works fine.
Don't drive the tractor with it though,just pour it in,rock the tractor a couple of times,let it soak for while,then drain.
If you have the time,let the drained diesel sit for a while,so the flushed out crap will separate from the diesel,so you can take the separated diesel and repeat the treatment until you are satisfied.
Then refill with fresh oil and off you go.

Good luck.

PS Don't let it soak for days though,i don't know how that will affect the oilseals.

I'm going to disagree with Rob!

Fords did not recommend us to use diesel in either the gearbox or the rear axle for flushing because it can affect the rubber seals and "O" rings.

Their recommendation, and what I have used since my apprenticeship on Nuffield and Fords in the late 1950's is kerosene. In fact Fords used this to dilute the oil in the hydraulics way back in the days of the E27N and through to the '000 nd series in the 1970's and 80's, in cold conditions and when the piston pump on the 3000 suffered from cavitation problems. And it works. Done it many times.

You can put a couple of gallons (10 ltr)of kerosene in the gearbox, mixed with a quart (1 ltr)of engine oil and drive round up to a mile without any problems. Do not work the tractor though, just a drive round, then drain and allow to drip dry. Repeat if you feel it requires it. This method was fully approved by the Training school for both gearbox and rear axle.

You know your stuff!!!!!!!

Now to find someone that sells kero.

Brilliant will attack that once i get the motor back in and these bloody brake drums off and back on.
