I recently purchased a Delta left-tilt tablesaw model 36-978 and have been having a problem with the motor dropping. The manual says that the weight of the motor should provide the correct belt tension but what is happening is the weight of the motor is stretching the belt and causing it to fall on it post mounts. I have thought of retroactively adding a support for the motor to keep it from falling below a certain level but I shouldn’t have to. Has anyone had this problem?

Is the belt the correct length for the saw?

It is the belt that came with the saw so my assumption is that it is the correct length.

May want to double check to make sure it is the correct belt. Another option would be to replace it with linked belt such as the following.

I actually have an extra linked belt but when I put it on, the weight of the motor also stretched it causing the motor to drop. I guess I can keep removing links until the motor weight doesn’t cause the motor so stretch the belt to drop it.

Is this a new saw? If so I would think you should call a Delta rep and tell them what is happening. They may have been contacted about this problem before and could give you advice on correcting it, or maybe they could replace it under warranty.

Yes, it is a new saw and I have gone to the Delta website and posted my problem. However, I haven’t heard anything back from them and noticed this site so I decided to post the problem thinking that someone might have had a similar experience and have come up with a solution.

Perhaps the motor or motor bracket are mounted to the wrong set of holes. Is there a way to adjust the mounting position? Can you go to a retail store that has this saw and see how that motor is mounted?

Gotta believe that it’s something simple (which I don’t mean as an insult). As you mentioned, you shouldn’t need to resort to making modifications to fix this.

Or maybe you could post a picture of the problem here and a friendly LJock could compare to his/her saw…

It could be that the motor mounting plate is reversed but I have double-checked the instructions and it appears correct. Now, there is a woodworking store not to far that has this saw so I can go and check it out and verify that it is mounted correctly (no insult taken because I will be the first to admit doing something like that many, many times over the years). If it happens again I will post a picture.

Well I have to laugh at myself because after visiting a local woodworking store and looking at the correctly put together saw, the problem is that I put the mounting plate on upside down (or reverse, depending on the point of view). With the mounting plate on correctly, the plate itself halts downward motion but mounted the way i have it, the entire weight of the motor is on the belt which stretches when in use and allows the motor to drop. It only took about 5 minutes to correct. Add one more thing to the list of things not to do in the future. Thanks everyone for all the help!!

Glad you got it worked out. Looking forward to seeing some projects from the saw.

It’s happened to all of us in one way or another. Welcome aboard.

For future reference… I had some problems with my Delta saw. I tried contacting the customer service folks via the web. They never replied, even after multiple postings on their site. I eventually called during regular business hours and had almost no trouble getting them to take care of me.

Also, be careful when trying to buy accessories for your saw. I bought the ones listed in the owners manual only to find out the manual they gave me was for the old contractor’s saw models, which were right-tilt.

Thanks for the customer service information because, to date, I have yet to hear anything back from their customer support via their website. Since the problem has been corrected, then it isn’t any big deal. I did notice other posts where someone had attempted to purchase a saw blade insert and followed the Delta proscribed item numbers only to find out that they didn’t fit and the numbers were incorrect in the manual. I am hoping that I won’t be adding things so soon after I purchased the saw but everyone knows how that goes. Thanks again everyone.
