We got a broken delta belt sander. We didn't know what the problem was, but after gathering the right tools and a bit of part searching and ordering, we could get the replacement parts. Then, after few hours of diagnosis and labor, we were able to get the belt sander up and running again!

Here is how we fixed it.

Step 1: Tools

To be able to get started, you'll need the following tools:

- Screw drivers ( 3 standard sizes).
- A hammer.
- Set of allen keys (different sizes).
- Thin wire.

<p>Just got mine tuned up and put a new drive belt on there. Everything was working fine until I put the plastic guard and disc plate back on- it became evident that the drive belt was slipping off the gear and cutting into the guard.</p><p>Am I to understand that this is similar to the tracking of the sanding belt? In that it's a balancing act to keep the belt in the right place? Or am I missing something? Taking the plate off is a real pain in the ass, so I'd like to know what I'm doing before I go any further.</p>
<p>Somebody can help me?</p><p>Mine is a Sears 6&quot; disc x 4&quot; Belt sander that started to fail to keep the belt on the rollers: If I install the belt centered the rollers, it takes about 20 seconds for the belt to start &quot;walking&quot; towards either the front or the rear of the machine, regardless of the adjustement of the right side roller (if I turn the knob to one side, initially it tends to stop the belt running out of position, but makes it slowly start to go to the other side, so that I'm never able to keep it running centered. This problem was not present when the sander was new, and it behaved OK for three years, and then started acting. Any suggestions? Amclaussen (amarquezclaussen at Hotmail.com)</p>
<p>Nice instructable :) Sadly this one doesn't help me. I have a similar belt and disk sander. It is marketed by a company called Clarke here in the UK but it is also very similar to one with the 'Titan' name also. With mine the motor has burnt out completely :( A new motor is &pound;75 (roughly $130 to $140US dollars). To get the motor fixed is around &pound;150. Way over the top in both cases. So I'm looking at adapting another motor to put in its place. Has anybody ever done this with this style of sander?</p>
THANK YOU for posting this helpful instructable. I have the same Delta sander. <br> <br>Any advice on removing the aluminum disc? Mine is stuck! <br>I'm very familiar with the set screw accessible via the top with a hex key. I have taken it out completely and replaced back into position multiple times. With limited view and access, it's much like Arthroscopic Surgery! <br> <br>As I cannot remove the disc, I also am unable to remove the black plastic housing which is positioned behind the disc. In order to check out the belt, I had to improvise and made my own new &quot;access hole&quot;. I riveted part of CD to use as my pivoting cover. Actually very functional. <br> <br>I was able to see that my belt is worn strangely. If you think of the ridges as running horizontally, I see that the left 50% of ridge is about completely worn away. The right side still looks OK. The belt has come off FREQUENLTY. I'm able to get the existing belt back on properly. But - I'm guessing a new belt will certainly help. <br> <br>Unfortunately, I'm not sure I can replace the belt without getting access behind the black plastic cover. Any suggestions on how to get the aluminum disc off? Would you have any suggestions? I've put a couple pictures here to illustrate...
I finally figured out how remove the stuck &quot;aluminum sanding plate&quot;. After peeling off the sandpaper disc, I noticed 3 holes visible from the outside. I hacked together a custom &quot;gear puller&quot; and it worked! See photo here. Also, I plan to put up some detailed notes in a separate instructable. You can find it by looking for: &quot;How to Remove a Stuck Disc Sander Disc&quot;.
Hello, Im in need of assistance, Im about to buy a second handed belt sander, exact same model, only thing is, the rubber belt is missing, but the motor seems to work just fine, if you could only send me more info on the rubber belt, like measure length and wide it would help me a lot with my decision. Thanks, by the way, Nice instructable, very detailed.
i have that exact same belt sander. it was making a squeaking noise and the engine did not run smooth, so i opened it up an had to loosen some of the screws with some liquid wrench. i discovered the problem was that the disc was loose so i secured it. then when i ran it again it did not squeak but it was still rough sounding. then it stated smoking, and slightly caught on fire. now it does not run but when turned on it makes a buzzing sound. i think it probably short circuited because of the oil, and burnt out the motor. do you think it would be possible to replace the motor?
Absolutely. A wonderful instructable. Thank you for taking me through all the steps. I had a similar problem with a Ryobi sander, and the drive belt was the problem. I wouldn't have even known what to look for had I not seen this. So I wanted to thank you for saving me $60 in repair shop costs. :)
Hi could you post a picture of the &quot;drive wheel&quot;, the part that is in contact whit the sandpaper belt and makes it spin around, cause i am planing to build a home made belt sander and was wondering which shape and textured it had and hoped you might have a picture of it. Anti_dolph
