TORQUE CONVERTER CLEARANCE CHECKS
TORQUE CONVERTER CLEARANCE
Dial Test Indicator Group
There must be a minimum radial (running) clearance
between the inside diameter of the rotating housing and
Check the clearance between the inside diameter of the
rotating housing and the turbine as follows:
a) Install tooling (A) in four positions in the rotating
housing as shown.
b) Put the rotating housing on a smooth fiat surface.
Install turbine (I) in the housing.
c) Put tooling (B) in the position shown.
d) Push turbine (I) toward tooling (B) until it makes
contact with the inside diameter of the rotating housing.
Adjust the dial indicator until it is on zero. Slide the
turbine 180° away from tooling (B) until it makes contact
with the other side of the rotating housing. Make a record
of the dimension measured.
e) Make this check at several locations around the
housing. Make a record of each of the dimensions
measured. The largest dimension measured is used
for the clearance between the two parts. The total
clearance measured across the diameters must be
.020 to .040 in. (0.51 to 1.02 mm) With a maximum
permissible clearance of .045 in. (1.14 mm). The
radial (running) clearance is half of the dimensions
