Disk Feed Gearbox Rebuild AMMCO 4000/4100

[@noone9929]

As a factory-trained Ammco service tech I've collected a decent amount of genuine Ammco parts over the last 40+ years. I'm retiring and have a parts inventory list if you are interested.

Good evening you say to use a lot of grease but where do you install the grease before installing the unit? Thank you and God bless you ✝️✝️✝️

[@handydandyupgradesinc7164]

Everything should be covered in grease and the well at the bottom should be full.

[@handydandyupgradesinc7164]

I like to see a cup and a half - 2 cups of grease in there.

[@nathan484848]

@@handydandyupgradesinc7164 what kind of grease to use in the crossfeed and the drum brake gearbox?

[@handydandyupgradesinc7164]

@@nathan484848 thanks for the call. I want to put this here - for colder climates use a thin brown grease like for barrings. In colder climates the grease can thicken and you want a nice thin grease.

Dandy do you have a video on the 4000 drum feed gearbox rebuild.

[@MakingStuffUp1]

yes we do kzbin.info/www/bejne/apnYpn6HYseNr8U complete drum feed gearbox assembly.

[@henrymiecz8566]

Where do you get the paper washer that you installed at 2:54? Do you make it yourself? If so what type of paper?

[@MakingStuffUp1]

matchbook covers work fine.

Could you make a video on some of the options to modify the ammco 4000 to accept larger brake rotors? I know the gold option is your power feed but it is expensive. I have seen other options like changing the lead screw nut and changing the twin cutter platform. There may be pros and cons though.

[@MakingStuffUp1]

Its in the works to do a series of videos on cutting the big stuff. The extension plate is not stable enough in my opinion. Tends to have chattering issues. Excellent question. Short answer is it comes down to stability of both the rotor/drum and the cutting tooling. Turning rpm too.At some point in the future Im thinking of doing a variable main drive motor upgrade or make some better pulleys Slowing down the arbor speed is a must at like 16 inch diameter.

[@roberthayes5037]

Andy, do you have any videos showing how to take it apart properly? Thanks

[@johnpeters631]

Hi how are you doing ? I have an AMMCO BRAKE LATHE. And it does not have a motor to feed the disc cutting knives table is that a normal thing or does this one have a missing part? And if I need parts for my machine would you have a recommendation for a place to get some?

[@handydandyupgradesinc7164]

It sounds like you have a drum only machine - if you want to upgrade it see our power feed upgrade video. kzbin.info/www/bejne/qJrQpHtorbuoY7c

[@jphefner2981]

My gearbox keeps slipping out of gear in fast speed only, literally have to use a silencer band to hold it in gear....the shifter handle is tightly secured to shaft but there seems to be considerable play inside the gearbox. What part do I look to replace in the gearbox ?

[@handydandyupgradesinc7164]

First thing to look at is the shifter. The only thing holding it in gear is the spring in the shifter handle. If its sticky it wont hold it in gear. Some times its the shifter plate is worn or miss aligned. If that doesn't solve it call me.

[@maxmoore2648]

Do you know if the long and short Lead Screws are interchangeable on the drum box?

[@handydandyupgradesinc7164]

They are interchangeable in the gear box BUT the length is important on the machine itself. You cant use a 4000 drum feed screw in a 4100. A 4100 screw can be used in a 4000, but only if it is cut carefully to length and dress the threads properly.

[@stockamx]

Where do you get new gears for it? Cannot find any parts?

[@handydandyupgradesinc7164]

What part do you need, we may have new or used replacement parts. Call us 1-833-768-8447

[@henrymiecz8566]

Question: I noticed your trap gear drive rod has slots running all along the entire rod. My rod has slots that stop short about 2 inches from the end. Do i need to get a newer rod like yours for longer travel or are they the same? Also would i then need a newer coupler as well? Yes i'm already getting a longer the longer slide bar and i will reverse the feed nut.

[@sinned96]

Why is the feednut backwards the lip should slip in the case. That keeps the feednut centered. The screws don't really keep it centered correctly

[@sinned96]

I don't know how many customers call me complaining that hey it doesn't go into gear it keeps skipping out. My first question is you didn't take it apart did you? They're like no we didn't take it apart. I remove the Box off the the machine and take it apart and that gear talking about they put in backwards but they swear they never took it apart. I'm like the factory doesn't put this in backwards

[@johnbennett5263]

Are there parts on Gearbox that often break and need to be replaced?

[@MakingStuffUp1]

Yep all of them can break one way or another.

[@Boyztobros]

My ammco brake disc feed doesn’t work when I turn it with the knob unless I pull and push it but when I put it in gear slow or fast the knob turns on its own but the disc feed shaft itself stays in place it won’t move on it’s own

[@handydandyupgradesinc7164]

sounds like the roll pin in the trap shaft has fallen out. its a easy fix. Remove disk feed box and replace the roll pin. it might also be just unscrewed from the trap shaft coupling. this happens when someone leaves it in gear and whines out the feed screw.

[@Boyztobros]

@@handydandyupgradesinc7164 thanks I’ll take another look at it now I appreciate the videos thanks 🙏

[@Boyztobros]

@@handydandyupgradesinc7164 I figured it out there’s a brass piece on the cone to the disc feed with 2 Allen bolts that piece snapped on the back side so nothing holding it to back and forth ...any idea we’re I can buy that piece??

[@handydandyupgradesinc7164]

@@Boyztobros We have them and now would be a good time to think about extending the travel. Maybe even doing the guide bar upgrade? An slap some new grease in the cross feed carriage. Make everything slide nice. An how does the spring boot look.

[@Boyztobros]

@@handydandyupgradesinc7164 not a bad idea but I just bought this lathe for cheap because I wasn’t working, do you have a video on how to extend and do the other recommendations? Thanks for the help 🙏

[@domjohnson2579]

Your vid says use lots of grease. What kind of grease or does it matter?

[@MakingStuffUp1]

Soft grease is what I like. We are looking for smooth action. The harder stuff has issues when it gets really cold. Molly greases tends to break sheer gears when its really cold. The drum feed gearbox wont work well with harder grease. There are trade offs with the soft stuff too. The juice runs out in hot climates. The soft brown stuff or the soft blue stuff seems to work pretty well. White lithium grease is nice for sliding parts.

[@sinned96]

I don't like those newer gear boxes with the single shifter Fork that rubs up against that gear set they are noisy

[@sinned96]

I was like oh my God you just pulled that shaft out of the gear. I understand why to show people what it's like sometimes I can get those to go through right away sometimes I'm like you messing with it for 20 minutes trying to keep those roll pins in place

[@waymonblevins6939]

I can't get the crossarm from the Main Shaft. The the 90 degree Arm that is used for Disk Rotors is Locks Up. I have removed the Rod from the Cross shaft but the 3 inch cross arm won't separate from the Main Shaft. Can You Help?

yes I can help, call me 1-833-768-8447
