Re: OT big lathe in Texas
I guess it depends on where one lives, here in Metro Detroit it is unlikely to sell for more that its scrap value.? ? Even in a machine tool desert, $3500 seems quite high.

Re: Bull Gear Greasing on zerkless 2J head
Well after taking in all this feedback, I think I'll let this sleeping dog lie...for now...until that time when I'm in a pause between projects and have a month to tend my shop improvements list, and probably do a more extensive rebuild than just swapping out the grease. It turns out the outfitting of a shop is a creative endeavor of it's own, and now it's becoming time to actually use the shop. Thanks all!

Re: Bull Gear Greasing on zerkless 2J head
The bull gear grease lubrication on the 2j head is for life.
The grease that is packed in there when it is built doesn't evaporate, doesn't leak out, doesn't burn up and as has been shown the grease is still there years later.
You don't keep adding oil to your vehicle engine, you drain the oil and refill it with new oil, and the same should be done with your fill for life transmission.
But if you don't remove the existing grease from the bull gear and replace it what is going to happen to the additional grease you pump in?
Simple through hydraulic force it will find a way to migrate out of where it no longer has room and start getting into places that SHOULD NOT have grease in them.
Too much grease in some areas causes excessive heat, why do you think bearing have a correct amount of grease to add and adding excessive grease causes overheating of the bearing.
The Bridgeport does have lubrication in areas that are a total loss system and a way of adding lube is provided, but unless there is a loss of lubricating fluid/grease you will end up overfilling it if you keep on adding lubrication.
Something I will say about fill for life components in motor vehicles, yes those components will last longer if they have the lubricating fluid changed regularly, but only if this is done CORRECTLY.
Yes I highlighted the word "correctly" for a reason, I've seen many transmissions ruined by lacking of servicing but I've also seen a number ruined/failed by incorrect servicing

Re: Bull Gear Greasing on zerkless 2J head
Like modern vehicle transmissions?? Seriously.?
Funny story.? I bought a glowing skull plasma display on ebay sold as working.? It was shipped in original box and foam but didn't work when I got it.? This was the second one I got like this so I was sure the tiny vacuum fill stem on the bottom had broken like the first one.? I opened it up and that was the issue.? ?Notified seller,? he said send it back.? ?On return,? he tried to credit me only half the price and said "it was working when I shipped it and the buyer opened it and said it didn't work and the item clearly says no user serviceable parts inside".? And he added a picture of that text!? ?Dumbass.? ?I replied when complaining to ebay that this was absurd and noted that I'm a professional structural engineer in multiple states with decades of experience repairing appliances and electronics.? ?Yeah they have me a full refund.? Neighbor gave me a shirt that says "I void warranties" on it...

I'm sure this was the first rebuild that head has ever had.? None of the standard oil cups, ports, etc go into that compartment of the head.? The quill/spindle assembly is completely isolated, so none of that oil drip could get there either.? Seems to run great now with all new belts, lube, etc.

Re: Bull Gear Greasing on zerkless 2J head
My mid 80s 2j has a set screw in place of where the zerk fitting is on this older (picture below)
The head placard says lubricated for life do not grease instead of providing info on what grease to use.

Re: Bull Gear Greasing on zerkless 2J head
Oh, yeah!? Mine is a little quieter than before (maybe), but now the power feeds work, everything is much, much smoother, and oh yeah the new clock spring makes a huge difference over the broken one.
Mine in a cnc head so the motor is under the upper housing and doesn¡¯t need to come all the way off to do this. I suppose that does make it a bit easier.
? 2 hours, really?? I...have doubts on that.? I completely rebuilt mine and it might take 2 hours just to disassemble it, especially if the housings still have the original pins between top and bottom.? This machine was pretty filthy and I would bet money had not ever been rebuilt since the 80s.? The gears still had plenty of nasty grease on them, however.? As for time, it took me two hours just to get the motor back in with the new belts and all.? Granted, it was my first BP rebuild job.? In contrast, replacing the timing belt, water pump, etc on my 2000 Toyota Tundra only took about 4 hours and I'm not a professional mechanic.
I have a mid 80s vintage 2J. It¡¯s pretty noisy but it could be that my dry walled garage really amplifies the sound and I am usually machining things with the door closed.
I rebuilt the head and changed all of the variable speed system bearings and bushings. It didn¡¯t really get much quieter.?
The point is it¡¯s a maximum of 2 hours to pull the head apart and replace the grease. You should change the timing belt while your in there.

Re: Bull Gear Greasing on zerkless 2J head
Daniel , I don't think these things were *GREASED* originally. Some possible differences in some later models having some SEALED bearings ?I
But the higher - OIL CUP -? is supposed to lube the back gear.? I believe the ZERK fitting is a common modification rather than original equipment ?
Packing the grease in there was often done for CLEANLINESS more than anything ?? Less OIL to constantly clean in this TOTAL LOSS lubrication system as it were.? ?For set ups that operated with the Head TILTED for long periods the grease was considered the best solution for longevity.
