1. Clean the outside surface of the torque converter.
2. Install the special tool into the converter hub.
3. WARNING: Always follow correct safety procedures while using press. Failure to
follow these instructions may result in personal injury.
Install the torque converter with the installed special tool into the arbor press.
Secure the press, apply enough force to seal the tool into the torque converter.
4. NOTE: Use clean dry shop air.
Apply air pressure to the valve on the special tool.

5. With air pressure applied to the valve, inspect for leaks at the converter hub, seams, drain plug
and studs. A soap bubble solution may be applied around these areas to aid in diagnosis. If a
leak is found around the drain plug, install a new drain plug and recheck the torque converter. If
any other leaks are present, install a new or remanufactured torque converter.
6. Remove the air hose. Release pressure and then slowly release the press. Remove the torque converter. Remove the special tool. Klj . 2 ba

Torque Converter Impeller to Pump Stator Interference
Check
1. NOTE: Front pump support may remain in front pump support and gear during this test.
Position the front pump support with the splines up.
2. Mount the torque converter on the front pump support with the splines on the one- way clutch
inner race, engaging the mating splines of the front pump support.
3. Hold the front pump support stationary and rotate the torque converter counterclockwise. zThe torque converter should rotate freely with no signs of scraping.
z If there are signs of scraping, install a new or remanufactured torque converter.

Torque Converter End Play Check
1. Install the special tool into the torque converter pump drive. zTighten the inner post until the tool is securely locked.
2. Install the special tool on the converter pump drive hub and zero the dial indicator.
3. Lift up on the special tool and note the dial indicator reading. zIf the reading exceeds end play limits, install a new or remanufactured torque converter.

Torque Converter One-
Way Clutch Check
1. Install the special tool in one of the grooves in the stator thrust washer.
2. Install the special tool in the converter pump drive.
3. Use a torque wrench to turn the special tool counterclockwise while holding the special tool stationary.
zThe converter should lock up and hold torque.
z The torque converter one- way clutch should rotate freely in the clockwise direction.
z Try the clutch for lockup and hold in at least five positions.

DISASSEMBLY AND ASSEMBLY OF SUBASSEMBLIES
Torque Converter Turbine to Pump Stator Interference
Check
1. NOTE: Front pump support may remain in front pump support and gear during this test.
Position the torque converter with the pump drive up.
2. Install the front pump support to engage the mating splines of the front pump support shaft on the torque converter.
3. Install the forward clutch cylinder and shaft, engaging the splines with the rear clutch hub.
4. Check for stator to turbine interference. 1. Hold the front pump support stationary.
2. Attempt to rotate the forward clutch cylinder and shaft.
„The turbine and torque converter clutch assemblies should rotate in both
directions, not exceeding maximum torque of 9.5 Nm (7 lb- ft), without any signs of
metallic interference or scraping noise.
5. If interference exists, the stator front thrust washer may be worn, allowing the stator to hit the turbine. In such cases, a new or remanufactured torque converter must be installed.
zThe converter crankshaft pilot should be checked for nicks or damaged surfaces that
could cause interference when installing the torque converter into the crankshaft. Check
the converter front impeller hub for nicks or sharp edges that would damage the pump
seal.
