Best way to clean out dirty gear box without removal?

[allwheeldrive]

Opened up my Torque Transmitters on the new coot. Front box is 100% sealed and full.

Rear box leaked any fluid above the drive shaft bearings. You can see in the picture most of the bolts are uneven and backed out (lose) hopefully snugging them up will stop leak. However I’m left with this disgusting gooy mess that will need to be cleaned out before new oil goes in.

Any tips for doing so while the unit is still in the machine? As nice as it would be to remove the box, gears, axles and apply new gaskets, and power wash. That isn’t going to happen.

I was thinking. Pumping sludge out, than spritzing and soaking in diesel fuel a few times. Than wiping down with rags.

Anyone got any other suggestions? Anyone know if diesel is safe on bronze gears?
Thanks.

I think your idea is fine. It will take several times but you should be able to get a lot of that out. I would just be concerned that your bearing may suffer from the contamination and ultimately fail. If you are depending on the Coot to get you places, I'd replace it. If you're just toying around with the coot, clean it and run it. Good luck.

Clean as good as possible and fill with diesel and run with no load(tires off ground)as diesel dosent offer much lubrication for those worm gears.
