Important Torque Converter
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
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 .
