DFI System Wiring DiagramCylinder Compression Measurement
NOTE
Use the battery which is fully charged.
Warm up the engine thoroughly.
Stop the engine.
Remove the spark plugs (see Spark Plug Replacement in
the Periodic Maintenance chapter).
Attach the compression gauge [A] and adapter [B] firmly
into the spark plug hole.

Electrical Leads
A two-color lead is identified first by the primary color and
then the stripe color. Unless instructed otherwise, electrical
leads must be connected to those of the same color.
Instrument
Use a meter that has enough accuracy for an accurate
measurement. Read the manufacture’s instructions ...
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
