Craftsman 1HP Sander 351.22638

JZiggy · Mar 5, 2016

I'm not sure if this guy qualifies as "vintage" or not, but I'm hoping someone will help me determine the approximate date of manufacture. It's a made-in-Taiwan Craftsman belt sander + disc sander. I bought it from a guy who did a lot of knifemaking with it. Ran very strong but was ready for bearings.

I will post complete pictures of my actual unit, but right now it is all in pieces!

In the meantime, heres a picture from an old eBay ad of an identical unit:

clients%2Fezsellusa%2Fphoto_sets%2F66884%2F100_4934.JPG

I tore the motor down tonight to address a rattly bearing. It took 6203's just like a block grinder. The original bearings were Nachi so I take that as a positive sign of overall build quality.

It has some more similarities with the old Block grinders, but the stator size and primary coil wire diameter are somewhat smaller than my 70's made 1HP Block.

In general I am pretty impressed with this sander. The belt sander housing and work table are heavy cast iron. The whole unit weighs 65 pounds!

How old would you guess this sander is? Late 90's perhaps?

I bought mine in the early nineties.

My forward belt idler bearings are gone. I've been blowing belts like crazy and finally noticed it sounded sort of strange when turned off and coming to a stop. Sure enough, that idler would not spin when finger tweaked. The other is fine.

When I am spending time in the workshop, there is hardly a day that goes by that I don't use this tool. Don't know how I got along without it all those years.

I don't have lots of experience changing what appear to be pressed in bearings (6602 LL they are) and am reluctant to proceed until I know what's what because I don't want to break it.

See some photos here: https://www.dropbox.com/sh/dsd5fwjzpnu6gxp/AABemVJ1Tp2FoBiJbhHeuN2La?dl=0 Image "...600.jpg" is the outside view with the snap ring removed, what you see when you open the cover. Other image is backside, facing motor.

If you don't have a DropBox account, look for the "No Thanks, Continue..." at the bottom of the popup when you crick on the link.

I have also attached images to this thread as a reply, which follows.

The shaft is frozen onto the bearings. It's been soaking in Kroil for an hour and does not want to budge when struck by a hardwood dowel and hammer.

Suggestions from the crowd, if 'yall please?

I have also attached the images of the front and rear of the idler pulley and bearings. The front view shows just the end of the shaft, and is what you see when you remove the dust enclosure, with the snap ring removed.

I'd call that unit "not vintage, but close, and very nice" - !

It'll be very useful for you I bet, and it sounds like you know what you need to do to make it run great...so, what did you pay??? :pimpflash

JZ,

Looks good. 2x42's belts are easy to find. Takes care of the bearings/bushings and you should end up with a great machine.

JZiggy · Mar 20, 2016

Hey guys,

Sorry I kinda forgot about this post!

pc_whocares: Those pulleys look just like mine. I bought some Chinese sealed 6202 replacements on eBay. I figure they may wear out a bit faster than premium bearings but they'll get all coated with sawdust and **** anyway, so premiums may not be worth it.

Try getting the shaft to budge with a brass driver, or just use a 3/8" extension... hardwood may not deliver enough shock to move it.

If you'd like, feel free to send the pulleys to me and I'll swap the bearings for you and mail them back.

Also, thanks for confirming a timeframe -- early 90's. Almost vintage

SweetD: I paid $80 for this sander. We actually agreed on $70 but the seller only had change in non-US funny money!

McB: Yep, with fresh bearings on the motor and pulleys this thing runs really nicely. I almost like it as much as my block grinder (but please don't tell Big Ziggy I said that).

pc_whocares · Mar 23, 2016

Thanks for the offer, JZiggy, but I got them out ok once I realized they were pressed in. I ordered the "6202-2NSE Nachi Bearing 15x35x11 Sealed C3 Japan" from VXB.com in Anaheim, paid regular US postage, ordered them on a Saturday, got them Tuesday "priority mail." How's that for service? $18 for both, delivered w/sales tax. Shipping was cheap enough I only bought one set just to see how they work.

The bearings I bought are nearly identical to the failed ones, except they are sealed with a rubber gasket on both sides of bearings. I expect that's how the old ones failed, as they were not sealed on the inside of the idler pulley.

I don't have a press but have a wide jaw vice and plenty of hardwood and brass backers so that I can likely press them in pretty easily. That will be today or tomorrow. Thanks again for your offer.

BTW, I paid $200 for mine, new, not on sale. I'd wager you can get the manual at Sears.com -- they are pretty good for that stuff.

pc_whocares · Mar 24, 2016

New bearing! Let's sand something...

JZiggy · Mar 24, 2016

Freakin sweet!

One of these is on my local CL. Would this particular sander be good for metal work?

JZiggy · Mar 28, 2016

Probably. The previous owner of my sander used it for knife making.

I had a similar CM unit, but it was rated at 1-1/2 hp. I would say it is not appropriate for metal work, especially not heavy metal removal like in knife making. The belt speed is too slow, but most significant is the lack of a contact wheel. Without it, all grinding is done with the belt pinched between the work and the backing plate. The belt quickly heats up and fails at the glue joint.

If the intent is beveling a knife edge, then sure---but shaping and contouring of a blade would be much better on a something along the lines of a Multi-Tool grinder.

JZiggy · Apr 21, 2016

Question to any of you guys that may own this same sander... can you snap a pic of the lower shroud that goes under the disc sander? Refer to part 54 on this picture:

Mine is missing that shroud which allows you to hook up a vacuum. I'd like to find some dimensions to see if I can make one. Thanks!

JZiggy · Oct 25, 2016

Thanks to a great friend from GJ (you know who you are!) I got the hookup on a BRAND NEW IN BOX Craftsman 1HP sander, made in 1997 according to the manual. This one is model 137.215280, but apparently the same as my original one. I figured you guys would like to see the "Christmas morning" opening experience, so here goes:

Ta daaa! It runs as perfectly as it looks.

My original sander with the 351 model number appears to be an earlier version, early 90's I think. There are a few minor differences like the older one has metal clamp handles and the newer ones are plastic. There is one bigger difference I wanted to get the forum's input on. While both motors tout that they are "1 HP Max developed" the older one has a rating of 8A while the newer has a rating of 6.2A.

Both motors are identical in appearance. Do you think this amperage rating difference means there is a real difference in winding design or had the motor rating regulations changed between the models?

toddmp · Oct 25, 2016

very cool multi-purpose sander. Hope all is well jzig!

Two different manufacturers: "351" = Colovos, and "137" = Rexon. I suspect the older model was built better, and would be the more powerful one as well based on the amperage ratings. The amps are more significant than the throw-a-dart-at-the-wall horsepower rating.

I have the 351.22638
Bought it new in 1994
It is a great sander. Mine has been used almost daily since new. And still going strong.
Mine is mounted on a stand so I can move it around.

I realize I'm bringing back an old thread but picked up this grinder for $50 yesterday. Awesome machine.

pc_whocares · Jul 15, 2019

Is there a question here?

Trillobyte · Sep 17, 2020

Manual no longer available at Sears.com/ Parts Direct for the 351.22638.
Anyone willing to email a PDF to me?
Thank you in advance.

tyandhope · Jan 15, 2021

Hello, could someone show me the correct way to install the sand belt. I have purchased new belts the same length side by side with the old broken one and they are the same length but I cannot find a way to install them. When I try thry always appear to be 3" or 4" short.

tyandhope · Jan 17, 2021

Hello I just purchased another sander model 113.226431 from an estate sale and forgot the angle slide, and now can't get it. I purchased this one for my son but I need to find another angle slide for it. The table is part H819493D that the slide would slide into. I found an older angle unit but it will not fit into the table slide. Anyone know where I can get one or have one to sell?
Thank you,
Stinson

pump for new eyes.

Might have to make one, or maybe another company sold this as well. I had good luck finding another sell and getting parts

The Cobbler · Jan 29, 2021

do you mean the miter gauge that slides in the table slot?

edit, just re read your post, what are the dimensions of the slot in the table?

sneezer41 · Mar 8, 2021

Old thread, but figured I would see if anyone noted the size of the start cap when they had theirs apart. Mine has needed one for years and we just slacken the belt on startup

I was thinking of getting a new sander, but this one is pretty rugged and with a new cap it should keep going

BTW you drop the table and pull down on the belt lever to install the belt, but tyandhope probably figured that out already

I replaced the bearings in the pulleys and it still making noise...
So I might be deeper into mine in the next couple weeks, if yes I will report back.

Good news, mine is the 8 amp!

sneezer41 · Mar 9, 2021

Bought mine new in the 90's sometime it howls pretty good but never bothered me. Forgot how beefy it really is till I tipped it over to try and gain access to the cap. And thanks, Been like this[slow starting]a decade, a few weeks probably won't matter

JZiggy · Mar 14, 2021

Curious if any of you guys located a start cap for this sander. Looks like sears 00291.00 is the one, 150mfd

Maybe this one will suit? https://www.amazon.com/dp/B00TECZ4NI/?tag=atomicindus08-20

Thanks for the link.

I had a 90's drill press that needed a bearing and pully and couldn't be found...
Then I posted here and a guy replied with a link to a Porter Cable one, and it worked! I wonder if Porter Cable also make this 1HP sander... ?

JZiggy · Mar 20, 2021

Welp, I gave the $9 Amazon start cap a try and it worked great! Very similar dimensions to the one in there which I suspect was also not original based on the electrical tape.

Cinci5 · Apr 6, 2021

Hey JZiggy PM me I don’t have enough post’s to PM you interested in pulley speed reduction you make.

lafester · Aug 24, 2021

Finally got my hands on one of these after several years looking. I've seen some 1/3 hp pop up but I wanted the real thing.
Seems to be in pretty nice shape but I'll go through everything before using it.

JZiggy · Aug 26, 2021

Sweet!!!

lafester · Aug 26, 2021

Yeah I think I got a good one. Everything spins smooth and straight, and there was nothing but sawdust behind the guard. I ordered up some cheap belts to see how I like it.

Coxxxy5 · Sep 3, 2021

Hey y'all. Glad there's recent posts cause I was about to resurrect this old thread. I've received one of these (6.2A motor) and it has always needed to be started by hand. Obviously you'd think the start cap. was out so I replaced that first thing...no change. Got into it and removed the internals and found this little hole blown in the windings. Still measures resistance so I guess that's what was always able it to still run with help. Question is: Is there a replacement stator coil I can buy to swap or a motor that's a known replacement. Or even schematics one could use to rewrap it myself. Any info on a direction to go would be great. I'm to the split in the road not knowing if it's worth doing. Thanks yall for any info you got.

Coxxxy5 · Sep 3, 2021

Heres info on the label. No pretty red any more.

lafester · Sep 10, 2021

I have no idea, but if it were mine I would just keep an eye out for another one.

Hey.. thank you for the reply. Thats all I know to do. If I had the info for rewinding and access to the right wire and resin and all that jazz I'd do it myself but thatll likely cost more than a new motor (or functional used one rather) I've got the windings separate if I could find just the winding armature and motor body to swap (not sure if my terminology is correct).

Breeeez · Feb 17, 2022

I inherited belt/disc sander mentioned in this thread. Craftsman 137.215280. I've always had to 'jump start' it by rubbing the belt to get the motor turning. I'm attempting to fix that problem so I ordered the start capacitor from Amazon as suggested in this thread. When I went to install it, I was surprised to see no start capacitor OR relay was present! Both are missing. Motor is 'hot wired' if you will. Soooooo.....I was thinking I'd find a relay. Looks like P/N ZE 604 in pics, but can't find one. Anyone know of a replacement relay that would work?

bruce l · Feb 25, 2022

I am looking for a platen and bolt for one of these Craftsman 351-22638 and all I find is discontinued. Anyone have extras laying around that they would accept money for? I live in southern Minnesota.
