Title: Cleaning with Molasses....
Post by: Brian on March 02, 2010, 02:49:04 PM
Well I had found a thread about this over on the HAMB board and thought I'd give it a try.



So I'm working on rebuilding a cone style suregrip unit. Yes I know
they say they can't be rebuilt but there was an article inone of the
mopar mags years ago that walked you through a rebuild, and plus I
figured I'd give it a shot...what the heck.



So I've had an original unit for many years, we pulled it, working I
might ad, from a friends 69 roadrunner. You can see why we chose not to
use it....the cross shaft decided to walk a bit through the case.

I have picked up spare parts over the last year or so and decided to
finally get around to cleaning them up so I can get on this rebuild. I
mixed up a 5 parts water to 1 part molasses bath and soaked the parts
for about a month, this method is not fast but does work if your not in
a hurry.



 So here are the before pics....

And after a month of soaking and a good cleaning with simple green and
water to neutralize the acids in the molasses....Those side bearings
were absolutely seized solid before going in the bath, after I could
spin them easily by hand!!

 Now it's some machining and a few shims and I should have the Franken-diff back in service.



 I plan on putting them in a set of 3.23's for the wagon.

I had a friend who used the molasses method to free up a rusted locked up smallblock..
We all laughed at him.
At first...
 
I'm a believer now.

Damn. . .I forgot all about that!  I did that when I was a kid.  Mom always had molasis laying around. . . She could never figure out what happened to it. . . .  But my Plymouth knew where it went.  LOL
 
Good Job Brian

And the best part...it's cheap!!  I got a 5 gallon pail of pure molasses at the local animal feed store for $15.  If I mixed it 10:1 I could get approx 50 gallons out of that one pail.

And you can keep using this stuff.  Just skim off the nasty stuff off the top and keep using it.  I have a big tote I'm using right now to clean up a bunch of old exhaust manifolds.  Then it will be some Hemi valve covers, and then.....

And when your done with it you can use it on your lawn, best if put on lawn before a rainfall.  So it's environmentally friendly as well!!(http://www.moparfins.com/forum/smileys/smiley4.gif)

I'd still rather use Ultra One.....the resto shop listened to me and tried it on a stuck 1911 Old Limited engine (priceless) and it now is a perfect running car in the AACA museum. The pistons, rods, camshaft, rockers, etc all were stuck in an aluminum crankcase - and I think molasses is a slight acidic.......which could harm the aluminum.

I was thinking the same thing when I started reading this thread,
perfect for Ultra One... not sure you could pour that on the lawn
though!



I'd love to see that Olds Limited, they were huge cars, isn't that the
only one left or something? as I recall from when I belonged to the
Olds club OCA, from an article in "Journey with Olds".

It will work quicker if you can agitate it slightly and keep it warm

Wonder what would happen if I dipped my rambler and let it soak... Would it come out all shiny and new?  LOL  ;)

At the very worst, it would come out rum flavored.

What an automobile! And what an honor it must have been to work on it, way to go BOB!

I'd love to own a brass era car. They are such raw machineery.



The wife works in a rural area, near Steve's Country Estate out in
Willet,  and she has a patient with a Model T truck in pieces in
the barn that she wants to sell, so I'se going to find out if it's
affordable.

I never heard of this trick until now. Now I want to find something to try it on! My wife sure liked the idea of me using environmently safe cleaners that I can dispose of safely. :thumbsup:

I don't use no stinking tongs or gloves....dryes the skin out a little but not too bad.  Not sure why you would let it ferment for 3 weeks prior to putting parts in?  And then have to wait another 2 weeks, for a total of 5 weeks.   Put the parts in right  away and wait 4 weeks...should be done by then.

Steve...A few of the guys who have done this have tried aggitation and temp and found no difference in cleaning times.

I know it works better with the Ultra one. . .   OK  Just a thought.

problem is the "weeks" part.....I heat U1 just to get it to work faster than overnight!

If I had to clean something with aluminum or zinc, I would definitely use Ultra one.(http://www.moparfins.com/forum/smileys/smiley4.gif)

Unless you wanted to clean off the oxidation.  Then just a couple of hours

Hadn't thought of that....might try this on a few old aluminum pieces and see what I can get away with.

from my testing, U1 is poisoned by zinc and by hardened steel (like a file) when the black crud sloughs off and mixes into the liquid. I soaked a 413 AFB carb (aluminum) in U1 and it came out clean, but the steel and brass parts were much cleaner than the rest. Then I soaked it in carb cleaner to get the passages clean. Mag wheel acid will get the aluminum oxide off of it.

Back to the original topic, Skinned Knuckles magazine once had a story about soaking rusty metal parts in whey...the smelly cheese byproduct. They said it took a while, but it wasn't destructive (sounds like Ultra 1 )
