SPECIAL TOOLS

Some of the procedures in this manual require special
tools. These are described in the appropriate chapter and
are available from either the manufacturer or a tool sup-
plier.
In many cases, an acceptable substitute may be found in
an existing tool kit. Another alternative is to make the
tool. Many schools with a machine shop curriculum wel-
come outside work that can be used as practical shop ap-
plications for students.

BASIC SERVICE METHODS

Most of the procedures in this manual are straightfor-
ward and anyone reasonably competent with tools can
perform them. However, consider personal capabilities
carefully before attempting any operation involving ma-
jor disassembly of the engine.
1. In this manual, front refers to the front of the vehicle.
The front of any component is the end closest to the front
of the vehicle. The left and right sides refer to the position
of the parts as viewed by the rider sitting on the seat facing
forward.
2. Whenever servicing an engine or suspension compo-
nent, secure the vehicle in a safe manner.
3. Tag all similar parts for location and mark all mating
parts for position. Record the number and thickness of any
shims while removing them. Identify parts by placing
them in sealed and labeled plastic sandwich hags.
4. Tag disconnected wires and connectors with masking
tape and a marking pen. Do not rely on memory alone.
5. Protect finished surfaces from physical damage or cor-
rosion. Keep gasoline and other chemicals off painted sur-
faces.
6. Use penetrating oil on frozen or tight bolts. Avoid us-
ing heat where possible. Heat can warp, melt or affect the
temper of parts. Heat also damages the finish of paint and
plastics.
7. When a part is a press
fit
removal, the information or type of tool is identified in the
text. Otherwise, if a part is difficult to remove or install,
determine the cause before proceeding.
8. To prevent objects or debris from falling into the en-
gine, cover all openings.
9. Read each procedure thoroughly and compare the il-
lustrations to the actual components before starting the
procedure. Perform the procedure in sequence.

10. Recommendations are occasionally made to refer ser-
vice to a dealership or specialist. In these cases, the work
can be performed more economically by the specialist
than by the home mechanic.
11. The term replace means to discard a defective part
and replace it with a new part. Overhaul means to remove,
disassemble, inspect, measure, repair and/or replace parts
as required to recondition an assembly.
12. Some operations require the use of a hydraulic press.
If a press is not available, have these operations per-
formed by a shop equipped with the necessary equipment.
Do not use makeshift equipment that may damage the ve-
hicle.
13. Repairs are much faster and easier if the vehicle is
clean before starting work. Degrease the vehicle with a
commercial degreaser; follow the directions on the con-
tainer for the best results. Clean all parts with cleaning
solvent while removing them.
CA UTION
Do not apply a chemical degreaser to an
O-ring drive chain. These chemicals dam-
age the O-rings. Use kerosene to clean
O-ring type chains.
