FUNDAMENTAL PROCEDURES
DYNAMOMETERA6E2014000042174WD testing/servicing
•Brake tester
Caution
•
To ensure the stability of the drag force of the viscous coupling always perform a brake test after
using the dynamometer or speed meter tester.
Note
•If there is a great amount of brake drag, it is probably due to the viscosity of the viscous coupling or the
center differential (RBC). To remove the influence of the coupling, jack up all four wheels of the vehicle
and verify that each wheel can be rotated freely by hand.
•Chassis dynamometer/speed meter tester
Caution
•
The vehicle may sway or surge forward when on the dynamometer. To prevent possible vehicle
movement, firmly secure it in place using steel retainers (chain, wire or similar) attached to the
front and rear towing hooks or to the tie down hooks.
•
Do not pop the clutch.
•
Do not accelerate suddenly.
Note
•The dynamometer/speed meter tester has two setting modes: propeller shaft removed mode and free
roller mode. After placing the vehicle on the tester and setting the wheels on the free rollers, start the
engine. For MTX vehicles, set the shift lever into second gear and gently, at low idle speed, release the
clutch pedal. For ATX vehicles, set the selector lever to D range, and slowly accelerate.

*5: Replacement of the timing belt is required at every 100,000 km (62,500 miles).
Failure to replace the timing belt may result in damage to the engine.
*6: Replacement of the timing belt is required at every 120,000 km (75,000 miles).
Failure to replace the timing belt may result in damage to the engine.
*7: If the vehicle is operated under any of the following conditions, change the rear differential oil
every 40,000 km (25,000 miles).
a. Towing a trailer or using a car - top carrier
b. Driving in dusty, sandy or wet condition
c. Extended periods of idling or low speed operation
d. Repeated short trips of less than 16 km (10 miles)
