Testing time delay (Lag test)
While the engine is idling at a frequency when the lever movement to select the neutral position before the operation is felt should be a time lag.
Testing the delay in time is to test the performance ND, 1-2 and NR accumulators, front and one-way clutch, clutch the reverse gear and brake bands front lower gears and reverse gear. Testing
| PERFORMANCE ORDER | | 1. Start up the engine. | | 2. Check the engine speed of the engine idling. The frequency of rotation of the crankshaft of the engine idling:
For Europe and Australia: 750-850 min -1
General: 700-800 min -1 | | 3. Move the selector lever from the position "N" to the position "D". | | 4. Stopwatch to measure the time from the lever to trigger transmission. | | 5. With the engine running, move the selector lever to position N and leave the engine running at idle speed for at least one minute. |
A warning  Engine operation for at least one minute at idling speed transmission fluid cools and prevents deterioration of its properties.
Before each subsequent testing for a sufficient time and cool the transmission.
Perform three tests on each mode, and calculate the average value of the time delay.
| 6. Similarly swipe tests when moving the selector lever in the following positions:
a. the position N> D;
b. the position N> D (switch O / D in position OFF);
c. the position N> R Time delay: The N> D 0,5 ~ 0,6 with
Time delay: The N> R 0,6 ~ 0,7 with |
