TORQUE CONVERTER CLEARANCE CHECKS
4. There must be a minimum radial (running) clearance
between the stator and impeller.
5. Check the clearance between the outside diameter of the
inner flange for the stator and the inside diameter of the
impeller flange as follows:
a) Put the impeller on a flat smooth surface as shown.
Install two ½/2" (12.7 mm) diameter rods (4) 18 in.
(45.7 cm) long across the impeller as shown.
b) Put stator (3) in position on the rods.
c) Put tooling (B) in the position shown. Slide the stator
toward tooling (B) until it makes contact with the inside
diameter of the impeller and tooling (B). Adjust the dial
indicator until it is on zero. Keep an even pressure on
the stator when it is moved. Move the stator away
from tooling (B) 180° until it makes contact with the
other side of the impeller. Make a record of the
dimension measured. Make this check at several
locations around the impeller and stator. Make a
record of each dimension measured.
NOTE: Turn the impeller around tool (A) and the stator when
different locations are measured.
d) The largest dimension measured is used for the
clearance between the two parts. The total clearance
measured across the diameters must be .009 to .015
in. (0.23 to 0.38 mm) with a maximum permissible
clearance of .024 in. (0.61 mm). The radial (running)
clearance is half of the dimensions measured.
