Important Torque Converter Installation Tips
1) PREPARE THE CRANKSHAFT AND CONVERTER
FOR INSTALLATION a) always check crankshaft for burrs and out of round b)
remove rust with emery and lightly grease pocket c) remove paint from
converter crank pilot with emery d) pour one quart of ATF into the converter
e) check the flex plate for cracks and worn teeth f) install the converter on
front of the transmission
2) CHECK CONVERTER TO FLEX PLATE ALIGNMENT a) after bell housing bolts
are tight, then check free movement of converter. It should have 1/16 to
1/8" of clearance between pads on converter and flex plate. If you have
more than 1/16 to 1/8", install equal thickness washers to reduce
clearance to 1/16 to 1/8". If not enough clearance, remove transmission
and check to see if converter is seated in front pump properly. b) draw
converter bolts up evenly so as not to pull converter into a bind causing
vibration and pump bushing failure. c) if vibration occurs after
installation, mark converter to flex plate and rotate the converter one bolt
hole at a time.
3) The number 1 cause of vibration is failure to prepare the
crankshaft for installation. Each time the converter is installed without
sanding out the crankshaft rust, removing the paint from converter pilot and
adding a little grease the converter may be drawn up crooked with the first
bolt, causing the converter to run-out and usually ruining the pump bushing.
The 2nd most common complaint on converters is a whine after installation.
This usually means too much clearance between converter pads and flex plate.
This draws the converter hub too far out of the pump drive gear causing the
gear to rock .
