Rumble is probably not normal. I've not replaced them, but worst case you may hear a click click sound, but not rumble. Welcome to the forum btw.Has anyone replaced the headstock bearings on an old Beaver WL 3400 36" lathe? The bearings are rumbling as I turn and the outboard end of the headstock shaft is getting hot. Or perhaps this is normal for this model?
Thank you Ryan!! That info is perfect!! Thursday will be tear down day and hopefully I can find the bearings nearby.Odds are that the bearing grease is bad alright based on your descition, happens.
Here's the manual with an exploded diagram: http://vintagemachinery.org/pubs/83/2132.pdf

Another restore thread:
(I suspect given the origins of the Beaver lathes the Canadian forums are likely to be generally more active with them...).
If you don't find them locally, try these guys... you'll need to know sizes, construction, etc.... but they ship quickly, not overly pricey.Thank you Ryan!! That info is perfect!! Thursday will be tear down day and hopefully I can find the bearings nearby.
Thank you, and it does. All that remains is to reassemble the little darlin' and take the tool rests to the machine shop for smoothing of the tool rest edges. Prolly not required, but I am a fussy old bugger.....It feels good to make progress doesn't it.... glad things are beginning to work out for you.
I've had good success smoothing out the edges of the cast iron tool rests that came with my lathe with a mill bastard file followed up with various grits of sandpaper. The cast iron is surprisingly soft and easy to work. Some of my other tool rests have a hardened steel edge, but those don't tend to get dinged up like the cast iron ones do. I also keep a bar of paraffin wax at the lathe to lube the edges on my tool rests....All that remains is to reassemble the little darlin' and take the tool rests to the machine shop for smoothing of the tool rest edges.

For machined surfaces like the bed of the lathe, and things like the bottom of the tailstock and tool rest banjo, I prefer to use Johnson Paste Wax.Thanks Vaughn, I'll try that while I'm waiting for the bearings to arrive...that wax would also work on the slides, I presume...
