TORQUE CONVERTER CLEARANCE CHECKS
There must be a minimum radial (running) clearance
between the turbine and stator. Check the clearance
between the turbine and stator as follows:
a) Put turbine (I) on a smooth flat surface. Install tooling
(A) at four positions around the turbine as shown.
b) Put stator (3) in position in the turbine. Make sure the
welded fins in the stator are not in contact with tooling
c) Put tooling (B) against the stator as shown. Move the
stator toward tooling (B) until it makes contact with the
inside diameter in the turbine. Adjust the dial indicator
until it is on zero. Slide stator (3) 180° away from tooling
(B) until it makes contact with the other side of the
turbine. Make a record of the dimension measured.
d) Make this check at several locations around the
turbine. Make a record of each dimension measured.
The largest dimension measured is used for the
clearance between the two parts. The total clearance
measured across the diameters must be .012 to .018 in.
(0.30 to 0.46 mm) with a maximum permissible
clearance of .030 in. (0.76 mm). The radial (running)
clearance is half of the dimensions measured.
