  • DP15501 Pulley

    I have the DP 15501 and the instructions state that the pulleys need to be at the same height. The center idler pulley slips into the head with no adjustment and sits about 1/8 low. The motor puller and spindle pulley seem to be in line. Does the idler pulley self-adjust?

    If the idler is sitting low, you might remove it and place a large washer as a shim to raise it up a little. I've read where people had issues with the motor being too high, but not what you have. 1/8" normally won't do much harm, but it is wise to get everything aligned as best you can.

      At higher RPMs the misalignment will contribute to vibration in the DP which could affect some operations. At the least it will have an affect on belt life. If you know it's out then why let it go? Fix it and be done with it. The washer shim suggestion will work if you can't align all three pulleys by adjusting the height of the outer two (quill pulley and motor pulley). I have an older Emerson made Craftsman DP which is basically the same as the RIDGID(Emerson made) DP.
      "When we build let us think we build forever. Let it not be for present delight nor for present use alone. Let it be such work that our descendants will thank us for, and let us think, as we lay stone upon stone, that a time is to come when these stones will be held sacred because our hands have touched them, and that men will say, as they look upon the labor and wrought substance of them, "See! This our fathers did for us."
