    Just looking for some ideas on how to remove the caked on 30 year old grease on my tansfercase and transmission. I have not done much more than scrape the lumps off. I have sprayed with brake cleaner and other cleaners but that stuff is really on there. Any ideas on how to break it down or soften it would be appreciateed.

    not for aluminum

    not for aluminum, but for steel/iron, oven cleaner works great. Hit the local dollar store, pick up a case and go to town on the transmisison and engine, axles, frame, etc. Just keep it off the transfer case.

    drag it to the car wash they have pretty good pressure on the rinse cycle or barrow a pressure washer and get some cans of foam engine degresserand soak it with that for a few minutes before you pressure wash it

    The car wash here even lets me bring my little ramps that I can drive up so I can have some more clearance underneath.....

    I had to use a piece of wood or a plastic puddy knife to getthe goo off mine. the car wash wouldnt even touch the stuff. then a wire brush after (not on a drill) then I could do the car wash thing.....

    Kyle,

    I think I am in your boat...that stuff is on there and I even struggled with the puddy knife. I will keep pecking away and then off to the car wash.

    Thanks

    Formula 409 & a wire brush, bristles need to be stout so you don't bend them but its worked well for me.

    Best to go in stages...
    1st powerwash to knock loose stuff off.
    2nd take an old screwdriver/putty knife/wire brushes and pry/scrape the gunk off.
    3rd soak with gnarly degreaser of choice
    4th blast with power washer again
    5th repeat above 2-5 until you get it all (becuase there is no way you got it all the 1st time!)

    1. Get a cheap tank-type sprayer
    2. Fill with Kerosene(or Diesel)
    3. Spray liberally and let soak, spray, soak, etc, etc
    4. Try carwash or rent/borrow a Hotsey...heated pressure washer.

    OR.....in place of the carwash/Hotsey....a wire brush...cup brush on a cordless drill or angle grinder + SS wire tooth brush:hillbilly:;)

    Steam cleaners work great. Unfortunately from my experience you'll be hard pressed to find someone who will let you use one due to the environmental issues (the city wherein the company is located will often come by and and test the sumps for oil/grease). If you can find one great, but be prepared to shop around to find someone who will be willing to take the risk.

    Sometimes all it takes is a little elbow grease!

    .2 could also be 100% mineral spirits. I soaked all of my axle parts in 5 gal buckets, and they came out like new. But it has to be 100% mineral spirits.

    I had good luck with a fine wire wheel on my cordless drill while applying liberal amounts of straight dish detergent followed by a little pressure washing. Did it to a used tcase yesterday came out shiny and clean without toxic chemicals or oil to dispose of.

    If you are rebuilding the part then disassemble, scrap off as much of the grease/crud as possible, and throw it in the oven. Bake at 600 degrees for an hour, remove, let cool, and bead blast the remaining ash off.

    Powder coat extreme chrome with red highlights....

    My favorite crud removal tool. ACE Hardware carries these. It will get almost any crack/crevice.

    Wish I had an oven. :hmm:

    Harbor Freight sells a sprayer that you attach to your compressor. I fill a bucket up with hot water and use this high pressure sprayer with a degreaser. It works very good. Although I usually hit it with a paint scraper first.

    makomark,

    got a part number on this sprayer? I have a big compressor and this just might help out. Thanks for all the replies.

    Pressure washer, :D Just picked up an electric one from Costco, less than $200, about 1500-1700psi and it works great. :)

    Side note, the word S C R A P E is a bad word in the forum...WOW!!, or it's just profiling the R A P E part??
