After shutting down my shop and selling all of my industrial machines I was the lucky recipient of a Craftsman 315 series – the saw has run well for the past 6 months but recently it has developed a nasty tick/knock which seems to be stemming from the arbor assembly – does anyone have experience in this area?

Does it do it when you spin the blade by hand, on start up or slow down, or does it tick all the time?

I have a 315.228410 that ticks on and off, but I’ve never really had any problem. I think mine is from my motor though.

Well that would be the weird part – if I disconnect the belt and spin the arbor manually there is only a very faint knock every 1/2 rotation. Conversely with the belt disconnected the motor runs almost silently (as quietly as a motor of its age can.). Connect the operation and the problem rears its head. I will upload a video this evening.

I had a sears contractor’s saw that had a similar noise. when I looked closer, the drive pully on the Arbor shaft had loosened and slid to the side. Moved it back and tightened it, the noise went away.

The symptoms you are describing certainly sounds like a loose driven pulley.

If it’s not the drive pulley:

I had this happen and found that the bearing on the pulley side went dry (but not bad). If you carefully take the arbor off, you can re-grease them with either a bell jar or heat vacuum. Or just buy a new one for four to six bucks.

I’ve checked the drive pulley and the darn thing is tight and in alignment… Still scratching my head over this.

If it is the bearing/s (which I can’t think of anything else it would be), it sounds like at least one of the balls has a flat side. They would have to be replaced. I found two on Ebay for $8.95 with free shipping. I only replaced the bad one because the saw side bearing doesn’t come off.

Its unfortunate that one cannot remove the saw side bearing – I am hoping that its not the one thats gone for a loop.

That definitely sounds like a bearing to me.

I’m sure that you have ruled this out, but I will ask anyway, do you have the belt guard on? Mine would make a sound very similar to that when the belt would get to close to the motor pulley. they keyway rubbing the plastic guard made a heck of a racket.

I think the bearings may be a good starting point… Worst case scenario I can find a donor saw and start to part it out. With regards to the belt guard, I removed it from the machine because it caused an impingement when lowering the blade down.
