TIGHTENING TORQUE CHART

TORQUE CONVERTER AND SHAFT

The torque converter consists of a impeller (pump), turbine and stator assembly in a single unit. The pump is connected to the engine crankshaft and turns as the engine turns. This drawing force is transmitted to the turbine through the oil which is recycled by the stator.

The transmission has two parallel shafts; the input shaft and the output shaft. Both shafts are in line with the engine crankshaft. The input shaft includes the overdrive clutch, reverse clutch, underdrive clutch, one way clutch, 2ND brake, low & reverse brake, overdrive planetary carrier, output planetary carrier and transfer drive gear. The output shaft includes the transfer driven gear.

TORQUE CONVERTER STALL TEST

This test measures the maximum engine speed when the selector lever is in the D or R position. The torque converter stalls to test the operation of the torque converter, starter motor, one-way clutch operation, the holding performance of the clutches, and brakes in the transaxle.

1. Check the automatic transmission fluid level and temperature, and the engine coolant temperature. Fluid level: At the HOT mark on the oil level gauge Fluid temperature: 80~100°C Engine coolant temperature: 80~100°C
2. Prevent all the wheel from moving during the test.
3. Pull the parking brake lever up, with the brake pedal fully depressed.
4. Start the engine.
5. Move the selector lever to the "D" position, fully depress the accelerator pedal and take a reading of the maximum engine speed at this time. CAUTION: The throttle should not be left fully open for any more than five seconds. If carrying out the stall test two or more times, move the selector lever to the "N" position and run the engine at 1,000 r/min to let the automatic transaxle fluid cool down before carrying out subsequent tests.
6. Move the selector lever to the "R" position and carry out the same test again.

Scheme 19

1. Stall speed is too high in both "D" and "R" ranges Low line pressure Low & reverse brake (B) slippage
2. Stall speed is to high in "D" range only Underdrive clutch (C) slippage
3. Stall speed is too high in "R" range only Reverse clutch (A) slippage
4. Stall speed too low in both "D" and "R" ranges Malfunction of torque converter (D) Insufficient engine output

Scheme 22

1. Warm up the engine until the automatic transaxle fluid temperature is 80~100°C.
2. Jack up the vehicle so that the wheels are free to turn.
3. Connect the special tool (oil pressure gauge) to each pressure discharge port.
4. Measure the hydraulic pressure at each port under the conditions given in the standard hydraulic pressure table, and check that the measured values are within the standard value ranges.
5. If a value is outside the standard range, correct the problem while referring to the «HYDRAULIC PRESSURE TEST DIAGNOSIS TABLE»(ref-276745-S05204386642008011000000) .
