    Default Older Reid Surface Grinder feed belt tightening

    Hey guys,

    I've got an older Reid surface grinder that I've had for several years. It needed some rehab before use, and I didn't have time to mess with it. I dug into it this evening, got all the old dried grease (yes, grease!) off of the ways, and coated with hydraulic oil. The gears and shafts inside are all well lubricated. What I found is that when started, everything runs smoothly and quietly, but as soon as I engage the table feed, the power feed shaft stops and the belt slips.

    I dug into it a little deeper, and the power feed belt is very loose. I can't seem to figure out how to tighten it. There is a jacking screw under the housing that the power feed shaft and pulley are mounted in, and I tried using that to tighten up the belt. But when I do that, it puts a bind on the shaft and it won't turn at all.

    Any tricks to this? I've included pictures of the machine in a Google Photos album here... I'd love any direction any of you could give me. As you can see, the grinder drive belt is pretty new, but the feed belt is quite old.

    So, my grinder is basically the brother to the knees in n this thread: Line Shaft Driven Reid Brothers Surface Grinder This guy indicated his was serial 445 and mine is 443. My belts are routed a little different than his. But, from the looks of it, we are looking at 20s or 30s. Anyone have one of these?
