STALL TEST
Inspection and JudgmentINFOID:0000000003849078
INSPECTION
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the
CVT fluid temperature is 50 to 80°C (122 to 176°F). Inspect the
amount of CVT fluid. Replenish if necessary.
3. Securely engage parking brake so that the tires do not turn.
4. Install a tachometer where it can be seen by driver during test.
NOTE:
It is good practice to mark the point of specified engine rpm on
indicator.
5. Start engine, apply foot brake, and move selector lever to “D”
position.
6. Gradually press down accelerator pedal while holding down the
foot brake.
7. Quickly read off the stall speed, and then quickly remove your
foot from accelerator pedal.
CAUTION:
Never hold down accelerator pedal for more than 5 seconds
during this test.
8. Move selector lever to “N” position.
9. Cool down the CVT fluid.
CAUTION:
Run the engine at idle for at least 1 minute.
10. Repeat steps 6 through 9 with selector lever in “R” position.

INSPECTION
Line Pressure Test Procedure
1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the CVT fluid reaches in the range of 50 to 80°C
(122 to 176°F). Then inspect the amount of CVT fluid and replenish if necessary.
NOTE:
The CVT fluid temperature rises in the range of 50 to 80°C (122 to 176°F) during 10 minutes of driv-
ing.
3. After warming up CVT, remove the oil pressure detection plug
and install the joint pipe adapter (SST: KV31103600), adapter
(SST: 25054000), oil pressure gauge set (commercial service
tool).
CAUTION:
When using the oil pressure gauge, be sure to use the O-
ring attached to the oil pressure detection plug.
4. Securely engage parking brake so that the tires do not turn.
5. Start the engine, and then measure the line pressure at both idle
and the stall speed.
CAUTION:
 Keep brake pedal pressed all the way down during mea-
surement.
 When measuring the line pressure at the stall speed.
Refer to TM-144, "
Inspection and Judgment".
6. Install oil pressure detection plug and tighten to the specified
torque below after the measurements are complete.
CAUTION:
 Never reuse O-ring.
 Apply CVT fluid to O-ring.

TRANSAXLE ASSEMBLY
 When using the drive plate location guide (commercial service tool:
31197CA000) (A), set it to the stud bolts which is used to install it
to the torque converter.
 When not using drive plate location guide, rotate torque converter
so that the stud bolt (B) for mounting the drive plate location guide
of torque converter aligns with the mounting position of service
hole.
 Rotate crankshaft so that the hole (A) for inserting drive plate loca-
tion guide of drive plate aligns with the service hole (B).
NOTE:
When not using drive plate location guide, insert stud bolt of torque
converter into the hole (C) of drive plate, aligning the drive plate
hole position and torque converter.
CAUTION:
Be careful not to strike the drive plate when installing the
torque converter stud bolt.
 Align the position of tightening nuts ( ) for drive plate with those
of the torque converter, and temporarily tighten the nuts. Then,
tighten the bolts to the specified torque.
CAUTION:
 When turning crankshaft, turn it clockwise as viewed from the
front of the engine.
 When tightening the nuts for the torque converter after fixing
the crankshaft pulley bolts, confirm the tightening torque of
the crankshaft pulley mounting bolts. Refer to EM-79,
"Exploded View".
 Rotate crankshaft several turns and check that transaxle rotates freely without binding after con-
verter is installed to drive plate.
 Never reuse O-ring.
 Apply petroleum jelly to O-ring.
