Hey guys – would appreciate a little help from my friends at LJ. I have a very old Crafstman “Commercial Dustless, 2 spd ” 4X24 belt sander, Model # 315.22670. The thing is a beast, was given to me many years ago from a fellow sawdust maker’s widow after he passed away from cancer. I cannot find any manual or other info for it buit thought I saw some comment online about old belt sanders like mine require periodic oiling. ??? Obviously this isn’t the case on newer stuff.

I would imagine it is from the early 70s – early 80s since it is an all metal housing and weighs a ton. Thing is rated at 1.5 hp.

Any help whatsoever on info/manual as well as the oiling issue is greatly appreciated.

Hi Andy – I just got the same model sander on Ebay – but it is incomplete. After looking at the parts diagram, it looks like the sander can be set up to use the dust bag, or without the dust bag. My sander does not have the small squirrel cage fan in the black plastic housing – so it is not “dustless”. As to oiling, I have the same era 3” x 21” Craftsman sander, and it has 2 points marked on the housing to oil daily – so I’m going to assume that the 4” x 24” sander has sealed bearings. I’m going to take a closer look at the sander this evening, and I’ll get back to you.

Is it a locomotive type or a sidewinder? The locomotives usually have a gearbox and require a specific lube for it. A picture would add to the fun factor here…

Hi guys, thanks for chiming in on this one. I posted this months ago and didn’t get any response until the other day seeing an email that I had some replies!

Gettonna/Lee – First, I don’t have a dust bag with mine so not sure if it came with one or not. Sounds like there is some truth that you have to oil these things. As to whether a locomnotive type or sidewinder, I’m clueless as to what that means, sorry. I never really used the sander after getting it many years ago. Then I attempted to use it to sand down my western red cedar deck and it didn’t run right, squeeled and I just shut it off. Went out and bought a 3X24 Hitachi which has worked Ok, although no personal attachemnt to the thing. I like this old Craftsman so threw up the post to see if anyone had any info or manual on it. Even Sears didn’t have anything, even to download. It’s a beast, would like to get it running like it should again. Will try to post a picture of it, have been busy getting my son ready for college.

Thanks again guys, appreciate you weighing in.

Have your say...
