Rebuilding An Old Ammco 3000 Brake Lathe

My next door neighbor owned an auto shop business his whole life and recently retired so he gave me his old Ammco 3000 brake lathe. I don't think it was ever cleaned in detail. It has many decades of oil soaked brake dust and metal bits. Using reasonable precaution to asbestos filled oily crud, I got it all cleaned up and am in process of rebuilding the machine so I feel comfortable using it. I found Andy called brakelathespecialist on ebay, who has been supplying me with great instruction on easy steps to take for the rebuild. His prices on parts are competitive too. Below is the list of the parts I replaced. The cost of parts for the rebuild is less than $200. So if you buy an old Ammco 3000 brake lathe, plan on spending about that much.

- main arbor shaft 1" (original might be ok, but was beat up badly, and worn threads)
- deep nut for main arbor 1" (just to match the threads on new arbor)
- the left & right accordion style dust boots (old ones broken)
- front cross-feed dust cover (old one broken)
- feed screw dust cover in lower-right area (old one broken)
- left & right main oil seals (old ones okay, just did them to be complete)
- rear seal hidden behind the drive pulley (old one leaking)
- tool post stud (threads on old one worn badly)
- one piece clamp nut (old one was multiple pieces and worn)
- 2 red tri-wing thumb screws (old ones were messed up)

If you have any questions, feel free to ask me.

i always kept a pair of bristle type paint brushes.. when cutting rotors.. i would lay them sideways across the cutting edges.. kept the cuttings from flying up across the rest of the machine..

i always wanted to have a brush company create a hinged brush that had putter brush angle to the heads that would work so much better.. with rubber bands instead of a fixed hinge.. so if it catches.. it just pops the rubber band off and falls in the filing tray.

a single brush works on the drum cutter..

congrats on the great find.. hope you got a full set of adapters. or most of the set..

Hi Wayne,

I'll have to keep your "bristle brush" tip in mind, jury-rig something myself to keep the machine clean. Thanks for that!

Yes, the machine came with everything in doubles plus more with nothing missing as far as I can tell, and it all seems to be in good condition. I used an old Ammco brake lathe years ago and so I am familiar with this machine and adapters & the rest.

I see in my initial post that I got my investment incorrect. Parts cost me near $300, NOT $200. I'd fix my post but don't see an "Edit" button. I just joined today, still learning the forum ropes here.

I wanted to post somewhere about the rebuilding of an old Ammco brake lathe because I searched everywhere and found nothing. I got very lucky connecting with Andy of brakelathespecialist on ebay. He saved my butt, avoiding making some serious disassembly mistakes.
