TESTING
4. Start the engine and bring the engine speed up to
full throttle.

full forward motion (Fig. 551). Operate without
any load for approximately 2 minutes; this allows
the system oil temperature to rise.
Figure 551
Note: Raising the system oil temperature will
make a difference in the readings you
receive. To complete the test accurately,
the oil temperature must be near system
operating temperatures. Suggested
temperature range 160° - 210° F (71.1° -
98.9° C).
