Cleaning A Engine To Get Ready For Rebuild

KCTractors · Sep 8, 2022

I have Allis Chalmers D-14 that has a tight engine. The tractor sat outside with the head off (How Long ? )I don't know.
I have the engine removed and took the oil pan off. Lots of sludge on everything. I don't think the pistons will come out without the sleeves.
How do I clean this thing and also get all the oil passages cleaned?
Anybody have a good running engine for a D-14 with power-steering?

I have had good luck with a product called simple green. Spray it on with a spray bottle, let it set for a while, then rinse with water. a pressure washer works great. Might need a few applications. Or take it to a rebuild shop they have a cabinet they put it in, with a lot of spray nozzles. Too bad no more hot tanks. Stan

I have cleaned many engines before rebuilding.
Pressure washer and purple power.
Took my Dodge slant six 225 engine to machine shop in town to have cylinders mic-ed years ago.
I had cleaned it at home.
Mechanic was amazed at how clean I had got it.

I wouldn't skimp. Take it to the rebuilders for cleaning and inspection. Cleaning the outside is just the beginning. The really important part is the oil galleries. They are equipped to get them really clean and put new plugs in if you want. They will also advise you if it is junk because of some fatal flaw that you may have completely missed.

No more hot tanks? Where at?

California for starters, doesn't allow them. The same wackos that are going to stop all gasoline cars in 12 years. If your state allows them, lucky you. They really did the job. Stan

Once you get it completely apart, it will probably clean up better than you think. Remove any galley plugs, freeze plugs, get access to every place possible.

The most important place to clean is the oil galleys, especially if there were a mechanical failure that introduced metal shrapnel, like a failed bearing. Harbor Freight has some assorted bottle brushes in various sizes. Squeeze the loop down so it will go in a drill chuck and go into every passage. You still need to do that, even if you have it pro cleaned.

Straight Purple Power is some strong stuff! HD has some big plastic storage containers, they are good for soaking parts. Oven cleaner will get the burned on oil off. Pressure wash as a final treatment.

Yet, everyone bakes them now. They would shot blast if there weren't fine machined surfaces.

I would start with presdure washer, tgen purple piwer and equ with a retired dishes sponge. Scrubbing with an old sponge is really efficient.

Well, not really surprised if its Cali. I thought this was something new within the last nine months when I had a block boiled. Guess its time for more advanced technology since everything is aluminum these days. When they halt internal combustion in 2035 ( why is the end of the world always 12 years away?) , you can bet legislation is on the way to get rid of the stuff already sold.
