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 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.
