Full-Time AWD MT Models
1. SPEEDOMETER TEST (Jack-up method)WARNING:
- Secure a rope or wire to the front towing hook to prevent the lateral runout of front wheels.
- Do not abruptly depress/release clutch pedal or accelerator pedal during tests even when engine is operating at low speeds since this may cause vehicle to jump off test machine.
- Avoid abrupt braking after tests.
- In order to prevent the vehicle from slipping due to vibration, do not place any wooden blocks or similar items between the safety stands and the vehicle.
- Since the rear wheels will also be rotating, do not place anything near them. Also, make sure that nobody goes in front of the vehicle.
1. Position vehicle so that front wheels are placed between rollers of speedometer test machine.
2. Jack up vehicle until rear wheels clear the floor, and support with safety stands.
3. Start engine with shift lever set in 2nd gear (for safety considerations). Perform speedometer tests.
2. SPEEDOMETER TEST (Free roller method)
WARNING:
- Secure a rope or wire to the front towing hook to prevent the lateral runout of front wheels.
- Do not abruptly depress/release clutch pedal or accelerator pedal during tests even when engine is operating at low speeds since this may cause vehicle to jump off test machine.
- Avoid abrupt braking after tests.
1. Position vehicle so that front wheels are placed between rollers of test machine.
2. Scribe alignment mark corresponding with centerline of rear wheels on floor.
3. Back up vehicle so that centerline of free rollers are aligned with mark scribed in step 2 above.
4. Drive vehicle onto free rollers.
5. Perform speedometer tests.
3. BRAKE TEST
1. Drive vehicle for a distance of several kilometers (miles) to stabilize dragging force of viscous coupling.
2. Place vehicle onto brake tester.
3. Perform brake tests.
Effect of braking force on viscous coupling torque:
Approx. 245 N (25 kg, 55 lb)
NOTE: If dragging force exceeds specifications, check brake pad or brake shoe for dragging. Abnormalities related to the viscous torque of viscous coupling unit may cause excessive dragging force. At this point, raise vehicle so that two front or rear wheels clear floor, remove cause of abnormality and check wheel rotation.
4. CHASSIS DYNAMOMETER TEST
WARNING:
- Do not abruptly depress/release clutch pedal or accelerator pedal during tests.
- Avoid abrupt braking tests after tests.
1. Locate vehicle onto chassis dynamometer tester.
2. Locate rear wheels onto free rollers.
3. Perform dynamic performance tests.
5. TIRE BALANCE TEST (ON-car machine)
CAUTION:
- Perform tire balance tests after each tire balance has been measured.
- Locate the vehicle so that its front and rear sides are equal in height.
- Release parking brake.
- Manually rotate each tire and check for drag.
- Do not operate clutch and do not accelerate the engine abruptly.
- If error occurs due to engine operation, do not operate balance's motor.
1. Raise vehicle so that left and right wheels to be checked clear the floor. Support wheels using pick-up stands.
2. Raise the other two wheels off the ground and support with a safety stand.
3. Attach on-car machine to wheels to be checked.
4. Drive wheel with engine and perform tire balance tests.
6. TOWING
1. Loading vehicle onto dolly or flat-bed truck.
CAUTION:
- Transport vehicle using a dolly or flat-bed truck whenever possible.
- Move shift lever to "1st" position and apply parking brake.
2. Towing with a rope.
CAUTION:
- Use a rope only when power train and all wheels are operating properly.
- The ignition switch should be in the "ACC" position. Never have the ignition switch on "LOCK" while the vehicle is being towed because steering will not be possible, since the direction of the wheels will be locked.
- Put the transmission in neutral.
- Never use the tie down hooks for towing.
- Remember that brake booster and power steering will not work when engine is "OFF". You will have to use greater effort for the brake pedal and steering wheel.
- Before towing, check transmission oil and differential oil levels and top up to the specified level if necessary.
3. Towing with front or rear wheels raised
CAUTION:
- Do not tow vehicle with only front or rear wheels placed on towing dolly or flat-bed truck. This may degrade viscous coupling performance or cause vehicle to jump off dolly or truck.
- Do not tow vehicle with rear wheels raised under any circumstances since this will damage bumper.
- Do not tow vehicle with front wheels raised under any circumstances since this will damage bumper.
