Turbo Model

  1. Reassembly precautions
    1. Whenever the O-rings, oil seals, and snap rings are removed, they must be replaced with new ones.
    2. Thoroughly wash the parts and allow to dry. They must be kept free from cleaning oil and dust.
    3. Reassembly procedure must be performed in clean place. Ensure that the parts are kept away from the waste threads or other dust particles.
    4. Cleaning oil tends to stay inside the front casing. Remove it completely by blowing compressed air.
    5. Ensure that the parts are free from rust. (Use specified hydraulic oil for rust prevention after cleaning and drying.)
    6. Reverse the sequence of disassembly procedures.
  2. Apply grease to the oil seal and inner surface of front casing (at bearing location).
    CAUTION: Make sure that the front body internal surfaces are free from damage. 
  3. Attach ST to front body. Using a press, install the oil seal.
