To facilitate actual operations, notes, illustra- tions, photographs, cautions, and detailed descriptions have been included in each chapter wherever necessary.
  • Page 11 Replacement Parts Replacement Parts must be KAWASAKI genuine or rec- ommended by KAWASAKI. Gaskets, O rings, Oil seals, Grease seals, circlips or cotter pins must be replaced with new ones whenever disassembled.
  • Page 12 1-4 GENERAL INFORMATION Before Servicing Tightening Torque Incorrect torque applied to a bolt, nut, or screw may lead to serious damage. Tighten fasteners to the specified torque using a good quality torque wrench. Often, the tightening sequence is followed twice-initial tightening and final tightening with torque wrench.
  • Page 13 GENERAL INFORMATION 1-5 Before Servicing Ball Bearing and Needle Bearing Do not remove pressed ball or needle unless removal is absolutely necessary. Replace with new ones whenever removed. Press bearings with the manufacturer and size marks facing out. Press the bearing into place by putting pressure on the correct bearing race as shown.
