I seriously doubt that how well the dust covers seal around the spindle has anything to do with oil flow rate. In the first place, the dust covers don’t come anywhere close to actually sealing to

Ken – you are welcome The question comes up from time to time so I thought it might be of interest . . . “High Speed” is relative . . . I must admit I seldom seem to run the lathe above 600 rpm

All 618’s have the same tapered roller bearings. And NO Atlas built 6” machine ever had babbit bearings. Robert Downs

Is the 618’s serial number 023653 or 028653? Robert Downs Sent: Wednesday, January 23, 2019 11:14 To: [email protected] Subject: Re: [atlas-craftsman IO] Welcome to [email protected]

Dave has a good point. Plus you should be measuring end float when setting tapered roller bearings, not radial float. Tapered Roller Bearings are normally operated with a preload. The Atlas 10” and

Hot Rodders of the early 50's could take them up to ~140 HP reliably with careful attention to building the bottom end up. There was a system of troughs the dippers on the rods ran in and a manifold

I have one of those in my 53 Chevy Advance Design truck. A marvel of Rube Goldberg style engineering. There is another intermediate style of shell bearing as used on my 47 Allis Chalmers tractor. It

True but not the old Chevrolet "Splash and Hope" rod bearings! Pressure feed to them came only with the 235 CID "Powerglide" motor in the 50's.?? Bill in Boulder CO USA

The Atlas-built machine database (currently 89% Lathes) is in the Files section of /g/atlas-craftsman/ and click on Files and then on 12a Atlas-Craftsman-AA Machines Databases

Robert, you pose a very interesting question here. Other than basic conservationism on the part of customers and producers I do not see why! But then the basic design of our lathes was done in an era

From the photo of the left hand spindle bearing, your machine was obviously a Craftsman 101.07301 (built by Atlas for Sears from 1939 until mid-1957). The highest reported serial number is 030965. At

Some extracts from the Atlas MOLO for interest . . . . And on the tightening / loosening issue for sleeve bearings . . . Best regards, Carvel Sent: 25 January 2019 10:19 PM To:

There should be a thrust collar with set screw trapping the bearing against the pinned ring. I have not done it but I presume that the way to remove the bearing is to drive the pin from the primary

Thank you David. I thought I was missing something. I may try that. I've already tried holding the gear and giving little baby taps on the screw with a punch. And yes, I realized after I typed the

It's supposed to be a very close hand fit, but some of mine are (were) quite tight and needed a light touch with abrasive paper not to stick. Suggest gentle prying with a screwdriver using the collar
