Hi,
I have a 1995 model Newman Whitney KF-24 gang ripsaw that is used for woodworking. A few days ago, we ripped up nearly 300 2x8x8' boards with no problem at all. After ripping the 2x8's, I took the blades off and set them to run a different width for another order. After I put the blades back on the saw, I noticed a bad vibration when I turned the saw back on. I didn't think there was a problem with the blades, but I did take the blades off to make sure that they weren't causing the vibration. After taking the blades off, the vibration was still there. The vibration was so bad that the laser guide on the saw got out of alignment. I first thought that the vibration might be coming from the rubber Sure-Flex connector between the motor and the saw arbor. I replaced the Sure-Flex connector with a new one, but the vibration persisted. When I took the old Sure-Flex connector off, I did run the motor without being connected to the saw arbor. The motor ran fine without any vibration. I wanted to make sure that the motor wasn't causing the vibration. There are 2 inboard bearings on the saw and 1 outboard bearing. I have a new outboard bearing ordered and should receive it on Thursday. I am planning to replace the outboard bearing and hope that the vibration will stop. Does anyone know how I can check to make sure that it is a bearing causing the vibration? And, if it is a bearing, how do I know which bearing or bearings is causing the vibration? I'm trying to keep from just buying a bunch of unneeded parts. I would rather just purchase the parts that I am actually needing. Thank you very much in advance for your help.
