Bringing this oldie back from the dead, did you ever figure out which sides of the AC bearings face each other? I am guessing they should be opposite each other. I'm thinking the bearing label is...
Yep, the pulley is threaded on and has set screws that just go into the threads. I think it had a mild loctite on it, not sure what though. Tightened it just a little and the backlash went away. It...
I think this sprocket might be threaded on. I will try to use a band wrench on it. It might also be the fasteners for the ball nut. I will update if I figure it out.
Definitely ball screw. Servo driven with encoder on the screw drive, not the motor so it shouldn't be negatively impacted by a loose belt.
I tightened that flange, but it didn't change anything....
Hello,
I have had an old IH manual mill since 2007 and regretted never getting the CNC kit which led me to purchasing a used Charter Oak made around 2014 that seemed all ready to go. Once I got it...
I am not sure if the backlash in the quill (I assume that is what the bouncing is from) is any different than before the seal replacement. It seems like it is worse, but I didn't really spend enough...
Thanks for the replies. As far as the bearings go, I didn't actually remove any during the seal replacement (http://www.cnczone.com/forums/showthread.php?t=26850). So I don't know how I could have...
I think I may have a problem with my non-CNC IH spindle. If I set up a block under the tool and then lower the spindle, there is about .03" of vertical slack that gets taken up between when the tool...
Hello Kimoyo,
I removed the motor by removing the bolts and lifting it off (you also have to disconnect the wires coming from the switch). Then I removed the top plate bolts. Next, I tightened...
Maybe all mills leak some, but this leak seems a little more than just 'normal'. I wonder if there is a flaw in the casting like youngfg had? I wouldn't be quite as worried about it except that if...
Well my leak is back. Its odd since I have not run the mill since I last posted and there were several days where nothing was dripping. Then I noticed a couple days ago that there were a couple of...
No plans to CNC in the near term, I feel like I have a lot of learning to do since I am brand new to the mill. I would love to CNC sometime in the future if I start doing minor production work. Who...
Here are all the pictures I took. The grub screws are in there along with pictures of the spring (and the little screw on the shaft you have to get it to attach to), the flange and its gasket before...
Yeah, I was fine on how much oil was in it. That wasn't the problem. Almost certain it was the top seal.
Thanks MAX711! I did as you said and got the spindle all the way down. That allowed...
Runner: I don't have the part number for the seals with me, but I will try and get it when I head back to the shop. However, from what Aaron said they are not always the same. I have the new model...
Thanks, but I have the manual. I just don't know what method to use to either break the seal on the bearing that the gear tree sits in or figuring out some other way to get that flange removed. At...
Close...its a Rong Fu knock off as well. In that head diagram, the seals that are being replaced are numbered 135 and the gasket is 131 (I believe).
Yeah, a picture would certainly help. Here is one with the damaged top seal in view. You can see the flange right in the middle, the spindle spline is poking up through it. Since this pic was...
Hello everybody, this is my first post here so I hope I am not covering something that has already been done before. I did a search, but couldn't find any info on this topic. Here goes...
I just...
