Other materials:

Piston Wear Inspection
Measure the outside diameter [A] of each piston 5 mm (0.20 in.) [B] up from the bottom of the piston at a right angle to the direction of the piston pin. If the measurement is under service limit, replace the piston. Piston Diameter Standard: 75.959 75.974 mm (2.9905 2.9911 in.) ...

Main Throttle Sensor Input Voltage Inspection
NOTE Be sure the battery is fully charged. Turn the ignition switch to OFF. Remove the throttle body assy (see Throttle Body Assy Removal in the Fuel System (DFI) chapter). Do not disconnect the connectors of the throttle body assy. Disconnect the main throttle sensor connector ...

Front Wheel Rotation Sensor Removal
NOTICE The wheel rotation sensor should be handled carefully, never struck sharply, as with a hammer, or allowed to fall on a hard surface since the wheel rotation sensor is precision made. Be careful not to get water or mud on the wheel rotation sensor. Do not try to disassemble or repair t ...
