Looks great>>
Very nice JetCone,
I am aware of similar type sludge as you mention...
Didn't know if you were aware of what we use "here" in the tranny biz to clean parts/cases.
Very close to your mentioned Kerosene, but we use Varsol.
It is a trademarked version of Mineral Spirits/Stoddard Solvent.
(On the fracking tower, its above Kerosene)
Exxon made a fine grade of mineral spirits, and patented it.
They removed the sulfur, and did one other thing that wasn't published, have never really known for sure...but its great stuff.
My mentor for tranny's was a retired Ford guy.
He told me that it would be hard for me to find varsol, as it was getting hard for him; it was a used as a dry cleaning fluid for years...something like since the 20's.
I have been lucky, we have one oil distributor that still carries it.
We buy it by the 55 gallon drum; when I started in '80, it was a $1.50 a gallon, now over $8...
Ford used a unique automatic transmission fluid badged as "Type F" in tranny's from early (>?) on to the mid/later 70's.
Anyway, clutch material in those Ford's are unique, and require only that fluid; but, when it burns the fluid, it would stain the case that nut brown/sludge color you have shown here.
We use a large, heavy metal hooded dishwasher to wash aluminum, or cast iron, cases.
When a really bad Ford of that vintage comes in, the aluminum case will be stained so bad, that the normal dishwasher will not make a dent as far as removal...(water based with a detergent about 10 times the strength of regular powder Cascade).
The Varsol used for even Hand/Manual cleaning of a tranny case wouldn't do it easy; but normal soak type carb cleaner is the bomb.
One of the features of Varsol was the no staining of white cotton.
My mentor reminded me that if I wanted to know for sure that a company sold Varsol, take a white man's handkerchief, dip in the suspect mineral spirits...hang to dry.
When dry, the kerosene/mineral spirits would always be yellow tinged; the varsol would be white.
And the Point?? only that here in the tranny work, kerosene left a film on valves in some valvebodies that would stick a valve...no rhyme or reason, could be stuck cold, or when hot.
Shops that didn't use varsol would usually not a touch a Ford of that era.
Anyway, useless stuff, but seeing that case and parts, made me think how hard you worked to get that stuff off!!
Good luck, and keep the pics coming.
>>Blackstone>>
I assume he is speaking of RTV (Room Temperature Vulcanizing) Red silione sealer.
Any of your parts stores for auto's has it...and many others...probably wally world by now.
Hope this Helps,
