I need help with installing the Z power feed on my bridgeport. Press fit?

[xalky]

I just got a powerfeed from Enco for my z axis. I nthe instructions it sais to remove the dial, dial socket and bearing flange. I'm stuck at the dial socket. I pulled the whole z crank shaft out of the knee, that was easy. The dial socket which is to the right in the photo seems to be press fit, but before I ruin something I gotta know for sure. This part and the bearing flange need to come out so that I can install the powerfeed. Any help would be greatly appreciated.



Here's the instructions that came with it. They're not very specific as to the dismantling of the existing machine.



Thanks
Marcel

Never mind... I got it. It's threaded on. That sucker was on there tight.hew:

by the looks of the drawing, you have taken it too far apart. they say one thing but seem to show another. "install the extension shaft" etc, looks to me to go over what you have taken a picture of. . . maybe ?

I wouldn't have taken it that far apart if I could have gotten the dang dial holder off. It was only 3 extra screws to pull that whole shaft out. Now that I know the dial holder is threaded on, I would have just taken a pair of channel locks to it. That collar for the thread dial has to come off. None of the drawings show whether that's threaded or not. After cleaning it out inside real good and peering in there with a flashlight it looked like it might be threaded so I stuck it in the vice and twisted real hard with some channel locks and it came loose. I also wasn't sure if i was gonna need that part again so i didn't want to ruin it. It turns out that I didn't need it after all. The power feed comes with a special one that has the ring gear on it as one piece.

I'm just about done installing it. I just have to set up the travel stops and track for it left.

Thanks for the looking out, it's much appreciated.

s:rofl: Thats too funny! I'm laughing because I looked all over the net for anything that would show how to take that off. Bamm....you had it sitting there the whole time. If nothing else it'll be here for the next guy.

Actually, it would be good if you posted that whole PDF somewhere here on this Bridgeport forum. That looks like a real gem. We could ask the mod here to make it a sticky.

---marcel--before i completely rebuilt my 1967-bridgeport model 2-j variable speed .i purchased a rebuild ''the bible'' called '' --''A GUIDE TO RENOVATING THE BRIDGEPORT ''2J'' VARIABLE SPEED MILLING MACHINE''-- published by ILION industrial services,llc. these books can easily be bought today and are also printed for other bridgeport models as well as the ''2j''. believe me when i say it is money well spent if you own a bp mill . buy one for yourself --you will not regret it. enjoy your powerfeed --i really do enjoy mine --as ''cranking'' that table up and down ain't much fun. re steve in mt.

She's ready to rock. I just finished it up.



While I was installing the stops for the power feed, I thought this would be an excellent opportunity to mount up an Igaging DRO for the knee.



If anybody is wondering why It's cocked over to the side like that.....It's so I could get at the table lock. If I put it straight up n down I couldn't get at the handle on the knee lock.

Now, I have to clean up all the mess. Damn, I make a mess when I'm working. :allgood:

I second this advise. If you own a Bridgeport, buy the book.

Here is a good source H&W Machine Repair The J and the 2J. Good news they are on sale right now. You will not regret the purchase. The books give all the tricks to a complete tear down of the entire machine.

Marcel, just me curious again, about how much power or tork do those have. My need is enough tork to lift a V8 engine block on the table.
I need two hands to crank this, enough I gotta sit down and rest. I already got in my mind these must be big bucks?? anyways good job
