    1-2 GENERAL INFORMATION Before Servicing Before starting to perform an inspection service or carry out a disassembly and reassembly opera- tion on a motorcycle, read the precautions given below. To facilitate actual operations, notes, illustra- tions, photographs, cautions, and detailed descriptions have been included in each chapter wherever necessary.
  • Page 13 Replacement Parts Replacement parts must be KAWASAKI genuine or recommended by KAWASAKI. Gaskets, O-rings, oil seals, grease seals, circlips, cotter pins or self-locking nuts must be replaced with new ones whenever disassembled.
  • Page 14 1-4 GENERAL INFORMATION Before Servicing Tightening Sequence Generally, when installing a part with several bolts, nuts, or screws, start them all in their holes and tighten them to a snug fit. Then tighten them according to the specified se- quence to prevent case warpage or deformation which can lead to malfunction.
  • Page 15 GENERAL INFORMATION 1-5 Before Servicing Press For items such as bearings or oil seals that must be pressed into place, apply small amount of oil to the con- tact area. Be sure to maintain proper alignment and use smooth movements when installing. Ball Bearing and Needle Bearing Do not remove pressed ball or needle unless removal is absolutely necessary.
  • Page 16 1-6 GENERAL INFORMATION Before Servicing Lubrication It is important to lubricate rotating or sliding parts during assembly to minimize wear during initial operation. Lubri- cation points are called out throughout this manual, apply the specific oil or grease as specified. Direction of Engine Rotation When rotating the crankshaft by hand, the free play amount of rotating direction will affect the adjustment.

  • Page 235 COOLING SYSTEM 4-5 Coolant Flow Chart Permanent type antifreeze is used as a coolant to protect the cooling system from rust and corro- sion. When the engine starts, the water pump turns and the coolant circulates. The thermostat is a wax pellet type which opens or closes with coolant temperature changes. The thermostat continuously changes its valve opening to keep the coolant temperature at the proper level.

  • Page 434: Caliper Fluid Seal Damage

    12-16 BRAKES Calipers Caliper Fluid Seal Damage The fluid seal (piston seal) [A] is placed around the pis- ton to maintain clearance between the pad and the disc. If the seal is in a poor condition, it could lead the pad to wear excessively or the brake to drag, which may cause the tem- perature of the discs or the brake fluid to increase.
  • Page 435: Rear Caliper Holder Shaft Wear

    BRAKES 12-17 Calipers Rear Caliper Holder Shaft Wear The caliper body must slide smoothly on the caliper holder shafts [A]. If the body does not slide smoothly, one pad will wear more than the other, pad wear will increase, and con- stant drag on the disc will raise brake and brake fluid tem- perature.
