  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 11 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 12 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 13 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 14 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.
