Mr. Kricketts, I have been trying to fix my Delta drum sander for the past 2 years, with no success; but 3 days ago I clicked on RUclips again, and right there was your video.
Yesterday I fixed my sander. Thank you very much, sir.
Thank You, my work is not in vain. Make some saw dust.
Threw ours in the bass lake in about 12 feet of water. Pretty consistent bass and crappie honey hole. That is the best it ever worked.
Thanks for the video! Will be tearing mine down this weekend.
Thank you for your helpful and valuable information recording this video for people to learn from! 🙏
Great vid....thanks for taking the time, making my life easier.
Thanks so much for the video. Just fixed my sander.
Just a note to say thank you for posting this. I was about to give up but we’re back in business.
Sooo glad I found this!!! Thank you!!!
Thanks for the video. I really appreciate it. Helped a lot.
I have this sander its been a nightmare. I picked it up cheep .i had the same problem as you took forever but fixed it then the feeder motor went replace that 350 later .now the plastic gears to rase and lower the bed stripped out 165 for new metal ones . hard to find some parts for this machine . waiting on parts still but omg nothing but problems but when its done will be a great asset to my shop . your vid was helpful thanks..
Hi Mr. Ricketts I bought a used Delta 31-250 Sander from my hardwood supplier for $100. One of the top rollers was missing but the replacement parts came with the sander. I put that in with no problem. I then wanted to check the bearings of the bed raising system. I watched your video, which is excellent. One of the lock nuts came off very easily, the bearing was fine so I lubed it a bit and put it back together. The problem came when I tried the next lock nut. I ended up holding the timing gear underneath with a channel lock while my wife used a crescent wrench to remove the nut. Long story short, the nuts on two of the lifters I tried to take apart were so tight that we broke the hubs of the timing gears. Now I am searching the internet to find replacement timing gears. I am not having a lot of luck. Since the three bearings I saw were in good shape I decided not to attempt to remove the fourth lock nut above the main drive gear. I hope your sander is still performing nicely. Very Best Regards,
As a follow up to my post 3 weeks ago, I have found a source for the timing gears that I broke. I am buying two new gears from the company and they will be shipped in less that a week. The company is State Tool Gear Co. in Newark, NJ. Phone 973-642-6181 and ask for Mike. Since they no have the pattern, they can probably make gears for you even faster.
One more follow up to my previous posts. The timing gears from State Tool Gear arrived on Saturday. They exceeded my expectations for fit and finish. I highly recommend them if you need discontinues parts for your sander or other machine.
Were they plastic or metal?
I'd found that the nut on the stem bolts were too tight and so the cranking was to tight.
I had to hold the crank and loosen the nut until the washers and bearing could spin freely...and left it. That did it.
The previous owner cranked it while too tight and striped the plastic gears which are $50 if you can fine them.
Many parts on these things are discontinued. The pivot bushings bearings are $150 each
Thanks for the video! I bought the same sander for the same price and it has the same problem plus the gears where broken. I fixed the gears with SDP-SI (part # A 1M 4-Y16032) and a bushing but it is still very stiff. I will take it all apart to clean the bearings.
Thanks for watching. I can't for the life of me find where I bought those bearings but it was under $20 for the 3 bearings. Sometimes bearings may feel good when removed but have flat spots and stick under load. The only other tips are to not over tighten the nuts and not over tighten the belt. Thanks for the part number of the bevel gears. Do you remember the cost of the gears. I am sure this is something other viewers will be interested in.
I think have broken one of the gears on mine while trying to tension it. the belt is no longer catching when i turn the handle. how do i know if it's broken?
Great thanks for the info, mine was given to me but never used it rite away, I went to adjust it today, was seized up but thanks know what to do to get it working better, thank you,
Love the intro music. Perfect 🤘
Crap, I was expecting "Jump in the Fire".
Haven't used mine in over 2 years because of the constant issues with table adjustments. Will take it apart one more time and use your advice for the fix and hope it works. Nice machine to have around when it works. Thanks so much for taking the time to help others. You are a true craftsman.
I have been battling my Delta Sander for 15 years and I’ve put hundreds of dollars in parts into it and actually had custom pinion gears made. But I never realized those bearings were in the levelers. This gives me the confidence to replace those because my table is hard to move up and down. I didn’t quite get where you bought those bearings they look exactly like the ones that are in mine. This is a great video I appreciate it good job..
Steven, you can google the part number and come up with the bearings. They are more expensive then what I paid. One thing that is important is not to get the belt too tight after installing new bearings. I will see if I can find them and put it in the description.
Here is the part. I know I paid about $5.00 each but don't remember where I bought them. www.motionindustries.com/productDetail.jsp?sku=00094487
Kricketts cool I just ordered 4
Thanks.....
@@kricketts4348 that link takes you to the wrong bearings. I ordered them and they were too big. It's not the same one as what you show on the box in the video. You might want to fix those links so more people don't order the wrong one's. Iirc those are TC1625 and what is needed is tc1220
@@swiftyforlifey1 Thanks. I updated the link. Sorry for the mistake.
I just bought one of these, and like an idiot I didn't check to see how the table moves; I just verified the drum and feed belt worked. It's setting in the back of my vehicle right now, and if the table binds when I set it in my shop I'll know what to do. Thank you.
merci
I've had mine for 20 years and the feed belt just broke recently. I replaced it but it's not been easy to get the belt to track.
Great Vid Thanks.
These are cool Sanders but....
Not much life to them. Repairs are in inevitable and for the cost its frustraing. I've done more hard work on this than my Toyota Truck to replace a belt.
Here's my experience with this machine:
Table height wheel was very difficult to turn. Belt was skipping teeth now and then, which throws the table out of alignment a tiny bit with each skipped tooth. I replaced the belt, hoping a fresh belt would work better. While I had the belt off, I performed the service shown in this video.
No improvement.
One viewer recommended greasing the needle bearings, so I did that. I also loosened the large nuts on the four table posts to finger tight.
Voila! Table height wheel turns easier than ever! No skipped teeth either!
Will report back after some use.
Hey, I have the same issue with mine (timing belt skipping teeth and so misaligned height posts). I’m not sure I got what you say. Where are located the nuts you hand tightened?
@@rifosi 8:10 - The large silver nut on each post. He's grabbing one at this frame of the video.
@@bullfrogpondshop3179 , thanks for your attention. Yes, makes sense that this nut should be just touching the washer-bearing-washer pile, and not crunching them. In my machine, I needed to screw this nut a little bit more using a wrench, to get no gaps between the nut and the w-b-w pile, taking care to still allow them to move freely side to side but not up and down. I did this yesterday. But it is still skipping teeth, unfortunately. Since I took all three posts (all except the one with a jam nut) apart and cleaned and lubricated all parts, including the now infamous thrust bearings, my last guess for the culprit is the timing belt. I took it off and although it looks okay, maybe 15 years of service being used eventually with more tension that it would be recommended, resulted in some stretch. The problem now will be to find a replacement, since I live in Brazil. I tried to Google the codes printed in it, but got no valuable information. Do you know some Goodyear online retailer that I could try? Thanks again!
UPDATE: I just found it in Amazon. I’ll place an order and let you know if it worked.
@@rifosi great news, good luck and yes keep me posted!
I eventually found out that in my case the problem is with one of the timing gears. It’s broken and the screw get stuck at some point. So I need a replacement. If someone has a non-working sander like this, I would buy this part if not damaged.
I got the delta x for free! used twice. the bed belt wouldn't turn. hit the reset button.. like brand new. now, here's the only problem I had. the two tension bars have about 5,000lb more than they need. remove them. then it sands perfectly.. so long as you start with the height just barely rubbing the wood. 1/4 turn at a time after that.
I had to think about what you were talking about. Those tension rollers have a very strong spring and I don't know why.
@@kricketts4348 once you thought about it.. it was automatic though. I took mine right out. now? what a beautiful machine. go by feel and sound.. vision too. doesn't matter if the wood doesn't touch the first time through. but once the perfect height to start from is found? no more than 1/4 turn at a time. it's beautiful without them. I think the spring order must have gotten mixed up with a steel grinding machine vs. fine woodworking.
@@garycarpenter2932 I think they had some left over elevator springs. I do the 1/4" thing when I get the board started but I have to put a strong hip push to get it started past that tensioner. Doesn't seem to be a real problem so I think I will leave them in for now but I knew exactly what you were talking about.
Another thing if the board is thicker at one end and you start at 1/4" and turn it down to touch it could jam the conveyor and trip the conveyor motor. Done that.
Yes, those rollers apply way too much pressure. I wonder if that's why I'm getting some snipe. They're an absolute byotch to install or remove, but I'm going to try removing them while I have the bed off. Thanks for the tip!
Great video. Followed right along, and replaced the three roller bearings.....moves up/down pretty well.
My kid got this used; didn't work quite right so he gave it to me to sort it out.
My problem now is the conveyer belt. I can't get it to remain stationery. It moves to the right and no matter how much I turn the adjustment (clockwise) I can't stop it. At this point, the length on the right side (front roller to back roller is 32 1/8" while the left side is 32 1/16"....but she still drifts right.
The rollers looked a bit worn, so I sanded them down to smooth 'em out. The belt is definitely not pretty, but seems to be intact.....although along the edges it sometimes does not lie flat.
Not sure what else to do to get the belt stationery. I've seen a new belt on Amazon for $50; just don't want to waste my money if that's not the problem.
Suggestions most appreciated.
Mine does the same but not enough to tear the belt up. I was going to try to flip the belt end for end and see if it tracks the opposite direction. That would tell if the belt is stretched on one side. Also I would check the head roller to make sure it is straight to start with.
@@kricketts4348 Brilliant! You nailed it. Squared up the drive roller against the table (it was quite a bit off) and she's working fine. Much thanks. (Do you do wife repairs?)
@@larryhavassy2280 Working on my second one but I may have it figured it out.
Did I miss you regreasing the bearing? It needs oil or grease on any thrust bearing.
Would you mind telling what the drum diameter is on your drum sander? Thanks in advance if you can help!
It seems to me that the likelihood of moving one of the posts while installing the belt is almost certain. Wouldn't it be better to get them close, then install the belt, then adjust the posts using the hex top?
Thanks for the great vid! My question, is I see that you seem to be missing the support plate? It works without it? Maybe that’s a factor? According to the parts diagram, there should be a large rectangular plate (406130720006) that rests on the 2 support bars that span the 4 threaded rods just under the bed. Mine came used without one, but all 3 “types” of this model show it in the diagram. What gives? Thanks again!
I don't see one on mine but I didn't dig too far. Maybe it is a plate that supports the sand paper on the bottom. It may be there but the sand paper is in the way. If it is not on the video then it isn't there. I don't remember it.
Thanks for the reply sir! seems to be working for you without this plate, so I’ll try that. Curious to hear any other owners - black support plate? No plate? I’ve also realized that the originally specified 1” bolts that screw through the plate, into the leveling rods are 1/8” too long, so I’m pretty certain the support plate was supposed to be there. I may just fab one. Thanks!
@@lostandfound404 late reply, I know, but hopefully it's of use to someone. The "support plate" is just a plastic shield basically intended to prevent sawdust from getting on the table screws. Older models didn't have this, they released it after the fact.
@@NKWoodworks Yes, mine doesn't have the "support plate"
Just looking to pick one of these up for $550. Good condition only used a half dozen times.
Is it worth it in your opinion?
Reviews are mixed.
I think it might be if it is truly used just a little. They seem to work good for several years but the table starts acting up after that. I waited until I found something cheap. The price of used was just too close to new.
They aren't that complicated. Maybe look at the drum closely for wear. I have also seen where people have problems with the clips that hold the paper but I don't have any problem.
@@kricketts4348 Thank you for your reply. I'm still debating it. If the was a little less I think I'd be all in. Just not sure.
Great video.
It does seem to be on the high side or maybe fair price but I look for a bargain.
@@kricketts4348 yes I agree.
One more (less important) question... the thrust bearings being spoken about in comments, that should be lubed - those are the same “washer bearings” that you do keenly discovered?
The washer bearings are technically a thrust bearing. They don't turn fast and shouldn't have too much pressure except for the table. I vaguely remember somewhere where it recommends a few drops of oil once in a while. Just remember any lubricant will collect sawdust. I left mine as is.
It’s called maintenance, all machinery with moving parts need lubrication. This is not a mystery, dirt clogs where oil or grease should be. Those are thrust bearings and even if crappy will work and last your lifetime if you just oil them. Full stop. Not everything is disposable!!
I bought this sander brand new about 15-18 years ago (guessing). It would not make a good boat anchor. As far as a sander............................I messed with it from new to 3 years old and it never worked as intended. I gave it to my brother who was going to mess with it..................Now we don't talk anymore. If someone wants to give you one, don't take it. If someone wants to sell you one, report them to the police as a crook. Shame on you Delta. Seriously, a large, heavy piece of shit.
I can see where this sander could be difficult for some. It does take a little bit of mechanical ability to figure it out.
@@kricketts4348 Funny. Mechanical ability? The space shuttle does take a little bit of mechanical ability to figure out. This machine is just garbage. Doubt you can find any other machine on you tube with so many videos about how to fix. And the fix videos about this machine are not from over use IMHO, they are fixing what Delta (or china) put together cheaply and poorly in the first place. I guess it goes without saying that I do have parts if anyone is needing some. Or wants an entire machine, but I will not provide a warranty.
@@grantparnes Somebody has some strong feelings.
Grant Parnes He was being polite, it’s a sander, it isn’t the machine, it’s the operator.
