Topic tags/keywords: craftsman saw belt blade

Hello all! I have a question i was hoping someone out there had an answer to. I have a 1988 model craftsman contractor saw and everytime i adjust the blade height the belt either loosens or tightens depending on which way I am moving the arbor. This is more of an annoyance than anything else but i was wondering if any one else got tired of adjust the motor height like i am. Thank you

On my Craftsman TS approx the same age, the motor is hanging out the back and pivots on a rod at the bottom of the plate. The top of the plate is a bolt (1/4×20 silver in my pic) that should not be too tight as to restrict the movement of the motor, it should only keep the motor lined up with the pulley for the arbor.
Maybe that screw is too tight and not allowing the motor to pivot.
I took a picture of mine to show you what I mean.
I took the belt cover off so you can see it better.
Hope this helps.

You know Charlie you could have imparted a little wisdom from your 30 years of experience and helped out with this guys question, but that’s right “There isn’t any benefit in it for you.”

Jay,
The belt is tensioned by the weight of the motor hanging against the belt and arbor. The bolt that you are constantly loosening/tightening as you raise/lower the blade is too tight. Just tighten it slightly to reduce vibration and the motor will raise/lower with the blade. I only tighten my motor in place if I am going to be using the saw at the same setting for long period of time.

Good luck and remember that lumberjocks is a place to share :)

Thank you all for your advice and for charlie I bought the saw second hand and did not get a owner’s manual. I am a maintenance mechanic by trade so the thought of leaving the bolt loose never occurred to me. I did not really like the idea of just leaving it loose so I came up with an alternative. I got a longer bolt from my stash and also came up with a compression spring. I tightened enough so the the motor will pivot but the spring holds it tight enough that it will not vibrate i attached a couple of pics. Thank you again.

you should not need the spring…if designed properly the weight of the motor should give you the needed tension. if not, a little oil at the arbor end or time for a new belt (they stretch with time and temp).

I have a Rigid 3650. I had to add a spring to mine too. The bolt kept backing out. I guess it was from the slight vibrations of the saw, I don’t know. Anyway, I added a spring like you did just to keep tension on the bolt. It keeps it from backing out. The motor can rise and lower itself like it was intended to do. It’s been on there for months now and I haven’t had anymore problems.

Not sure if you found an owners manual yet, but here is a link one that should be similar.

Jay I like the spring idea. I put a nylon washer there already, but a spring (sort of like the trunnion lock) might keep it from vibrating a little. Here is the link for the manual Brian wanted to give you. Good luck. -Jack
