Solid Clipper Seal Installation

    1. Make sure the seal bore and shaft are clean. Take out all burrs and nicks.
    2. Prior to installing the seal into the cavity, pre lubricate the seal ID and shaft. Apply a pre-lube which is compatible with the system lubricant. The pre-lube will help in installing the seal easily and prevent dry running during the first start-up. (Do not lubricate the seal OD or housing.)
    3. Seal lip must be guarded against damage from sharp keyways, splines, and screw threads. It can be done by both taping the keyway, inserting an element into the keyway or utilizing an assembly sleeve that fits over the shaft.
    4. The seal lip must be pointed in the right direction and push to the edge of the counterbore.
    5. Apply finger pressure to start seal into the cavity. Once the seal is started in housing, tap evenly with a soft-faced mallet all around until seated.
    6. Use a flat plate tool to drive the seal in the final position to complete the installation. The diameter of the plate must be big enough so that it contacts the face of the seal housing. It will ensure the seal is positioned straight and perpendicular to the shaft.

Split (R Series) Clipper Seal Installation

  1. The machinery cavity recess area should be cleaned up thoroughly. Take out all burrs and sharp corners. Provide adequate lead-in chamfers.
  2. Light grease or oil coating should be applied to the shaft area where the lip will engage. Do not use grease or oil to seal OD or machinery bore surface.
  3. Form a helix with the seal by separating the cut ends of the seal sideways. Do not try to structure the seal into a “U” shape. Separate the end far enough so that the seal can be slid over the shaft.
  4. Between the seal and the bore cavity, insert the garter spring over the shaft, joining the ends of the spring with the hook-and-eye connectors. Insert the garter spring into the lip carrier groove with the joint at least 45° from the split juncture. Push the seal to the bore cavity until it makes contact, making sure that the split ends are well aligned and positioned at 12 o’clock.
  5. Begin placing the seal into the cavity with the split juncture at the top, compressing the OD lightly, until the split juncture has been inserted to about one-third of its width. Continue to press the balance of the seal into the cavity, working away from the split, until the whole seal has been started into the cavity recess. Tap evenly around the back face of the seal with a soft-faced mallet until it is fully placed.
  6. Use a flat plate tool which will drive the seal flush with the housing to ensure the seal is installed square and perpendicular to the shaft.
