I picked up an old Delta/Rockwell 10" bandsaw a while ago (model 28-113) for peanuts - I don't think this model was ever considered particularly good (it's got the plastic wheels), but it'd be OK for the kind of stuff I'd use it for.
Anyway, the bronze driveshaft bearings were completely shot - but when I pulled them out so I could replace them, I found that the one on the drive pulley side completely blocks the grease fitting pathway!
It seems impossible that it was always like that; there's a cavity within the saw's cast frame which still had some grease in it (albeit not much). So I assume that the bearings have been replaced at some point in the saw's life; did the original (on the grease fitting side) maybe have a notch to allow grease in? Or perhaps a hole, and grease could flow between the bearing and driveshaft into the cavity (but this seems unlikely as the clearance between bearing and driveshaft is so small)?
Another possibility is that according to the parts break-down (e.g.
The bearings which were fitted were 10/16" ID and 13/16" OD (and 12/16" OD seems much easier to obtain, again perhaps suggesting that the saw has over-size replacements), and I've got some new ones to put in - but in order to fix the lube problem properly it would be useful to know what the original setup would have been.
