Just started reconditioning a pretty decent 101.07301 have some questions for the experienced!

[makeparts]

This 101.07301 looks to be in pretty good shape (Serial No.: 6L 025657). The gears/threads throughout look to be pretty good, but there are some small chips out of a couple pulley walls on the M6-79 Pulley and Gear with Bushings on the spindle, and a chip out of the M6-80 pulley on the countershaft hanger assembly. I think these chips are small enough that I could live with these while I get it running, and then replace them later.

I may have a franken-lathe, as it appears the Back Gear Assembly is a 2 collar M6-243X, but it may have been missing the M6-255 washer. Also, the Spindle Assembly looks like a 1 roller bearing & bushings spindle, even though everything I see shows 2 roller bearings in all the documentation. Am I on crazy pills here?

The lathe came to me almost fully disassembled, with parts separated into bags. The exception being the headstock: the spindle & back gears were still installed, and seemed to move pretty well, fairly smoothly. I have disassembled this, and put into baggies to manage it all, post a soaking in PB Blaster.

I think it's fairly complete, but I shall find out soon.

Again, the Back Gear Assembly looks like the 243X version with TWO M6-253 collars, but did not have the M6-255 washer...seems like it had the space for that washer...

Parts for Countershaft I might like to replace during reconditioning:
M6-109
L2-682 Collar

Parts for Backgear Assembly I might like to replace during reconditioning:
M6-249 Bushings
M6-253 Collars
M6-255 Washer (or at least share what the specs/material is, for this?) This assembly did not have this washer installed when I disassembled it, and put into bags for inventory management.

Spindle Assembly
M6-71 Dust Covers (or is this a generally available item for that bearing?)
M6-72 Dust Covers (or is this a generally available item for that bearing?)
M6-81B Bearing
M6-82B Bearing
M6-258 Bushing
M6-89 Spacer

I might be able to get away with just a full re-assembly, to get it moving again. What do you all think?
Are these parts available from Clausing, or a 3rd party? I sent a note to them asking about availability, but thought I would engage with you all as well.

I soaked everything in PB Blaster, and it all looks pretty good, the exception being the one bearing off the spindle seems rough to spin now - that maybe a function of the PB Blaster breaking down the lubrication in the bearing.

The machine is at a siblings, so I will get some pictures later this week and post them, but I really don't remember seeing 2 bearings on the Spindle Assembly, so I am freaked out a little, as Im clearly losing it, or it isn't a configuration I have the manuals for...

Is there a trick to removing/replacing the bushings in the pulleys/gears, castings?

any other thoughts or recommendations?

thanks in advance. Im looking forward to the community...

makeparts,

If your lathe is in fact a 101.07301, then you probably do not have a Frankenlathe. You are looking at the wrong parts list. The 101.07301 has two sintered bronze bushings plus a ball thrust bearing on the spindle. The spindle and headstock casting are different from those on the Atlas 618 and the later 101.21400 that replaced the 07301 in 1957. The only difference between those latter two after 1957 is the badge and maybe the paint color. They do both have most of the parts that you list as needed to replace but the 101.07301 doesn't have at least some of them.

Most of the parts are the same between the sleeve bearing and roller bearing models. The main things that aren't are the countershaft and the spindle assembly and headstock casting. But some of the parts on both assemblies are the same.

The exact configuration of the countershaft pulley and back gear sub-assemblies varied somewhat over the years, with some cases of the as-found lathes not having exactly what the parts list called for.

You will find one or two versions of the 101.07301 manuals in the Atlas and Craftsman area in Downloads. Read the instructions for use that you will find up above in the Sticky area before trying to access Downloads.

Unfortunately, Atlas never did an exploded view parts list for the sleeve bearing machines.

will do thanks wa5cab
I'll post some pics of the headstock items as I had them separated into bags... I had some pics on a tablet during disassembly, but it appears that they were deleted by either me or another user...hopefully I can figure that out with the correct manuals.

A photo of the headstock casting alone will tell whether it has Timken or sleeve bearings without even looking at the bearings. The 101.07301 has a single fillister head screw in front of each bearing. And a slot cut into the front of each bearing cap that the screw can close it up a few thousandths. Anyone with a 101.07301 should also get a copy of the 1950 Atlas 618 manual for parts identification and location other than ofthe spindle bearings, spindle, thrust bearing and countershaft bracket. All 101.07301's originally came with the 6" Type 2 countershaft whereas all but the early 618's and all 101.21400's have the Type 3. The pulley assembly is the same but the countershaft bracket of the Type 2 is much shorter that on the Type 3 and the pulley hanger hangs down instead of sticking up as it did or does on the type 2.

Hey I really appreciate you responding...
here are some pics I was able to get last night. It is a 07301, and the headstock has the fillister screws in front of the oilers.

 

[makeparts]

here's what came off the spindle. spindle was a little beat up...

 

[makeparts]

that thrust bearing is a Nice 5774. Anybody have a current quality replacement? should I go to RBC?
small ding in the spindle gear that drives the change gears, and the spindle step pulley has had a knock, too.

I'll get into an inventory of the the rest of the machine in the next 3-4 days...it's all in bags. The seller told me it was complete, but I have not verified.

Well, you're into it now for sure. I would normally just clean and lube and then re-assemble and see how it runs before looking for new parts. Worn parts v. broken or missing parts. A lot of times you discover what you need while in the process of putting it back together.

 

[makeparts]

The backgear looks ok, but the shaft is a bit beat up...same with the countershaft spindle...
the countershaft pulley has what looks to me like a non-standard pulley, for the motor belt...is that a "4"

lol yeah... the machine was pretty much fully disassembled, except for the headstock, and I figured since I was at this point, I'd get into it all...what lubes are you using?
