Froze up for 20 years

[GP Hansen]

I"ve decided to change the trans/diff sludge. It is a thick brown goo. My plan is to add several gallons of diesel and run it around the place a little bit and drop the drain plug and put in new oil. See any problems with this ?

I think usually people drain the oil first and then put in kerosene or whatever to clean it out.

I"d put a gallon or so of cheap oil in with the diesel just to be sure there is something there to provide at least some lubrication.

This sludge is so thick it hardly comes out it needs to be thinned.

yes I would put some oil in it. It doesn't take long to scar a shaft with out oil!

Put a space heater on it to get the rearend hot and it will drain . Probably 140 weight and in this weather it is a weeeeee bit stiff.

For 10 minutes of no load cleaning, no oil is needed (the residual will do fine) if you feel unsure, jack it up and run it W/O even weight. Jim

If your fill cap is large enough, I have taken a boat bilge pump and placed it in a catch container (bucket). Stick the hose in the fill and let it run with diesel flowing. I gave mine 10 minutes and it was cleared out of all the junk. Then I filled it with a mix of diesel and oil to get the rest cleared.

Ive done that several times to get it flushed good.

I pulled the transmission cover plate off and drained everything then scraped the goo out with a 2" wood slat. I/m glad I did, the sludge was so congealed and heavy I don"t think it would have ever thinned out and drained.
