TM 5-3805-260-24TORQUE CONVERTER CLEARANCE CHECKS4. There must be a minimum radial (running) clearancebetween the stator and impeller.5. Check the clearance between the outside diameter of theinner flange for the stator and the inside diameter of theimpeller 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 statortoward tooling (B) until it makes contact with the insidediameter of the impeller and tooling (B). Adjust the dialindicator until it is on zero. Keep an even pressure onthe stator when it is moved. Move the stator awayfrom tooling (B) 180° until it makes contact with theother side of the impeller. Make a record of thedimension measured. Make this check at severallocations around the impeller and stator. Make arecord of each dimension measured.NOTE: Turn the impeller around tool (A) and the stator whendifferent locations are measured.d) The largest dimension measured is used for theclearance between the two parts. The total clearancemeasured across the diameters must be .009 to .015in. (0.23 to 0.38 mm) with a maximum permissibleclearance of .024 in. (0.61 mm). The radial (running)clearance is half of the dimensions measured.3-176
