Section II. TORQUE

6-8. Description

a. The torque converter is composed of three

members: the impeller, the turbine and the stator. The

impeller forms the outer shell of the converter, and the

turbine and stator operate within the impeller, but turn

free of the impeller. The complete unit is mounted on the

engine flywheel and always turns at engine speed. See

b. The torque converter is filled with oil and when the

impeller is rotated by the engine, the oil in the impeller

vanes also rotates; and being subjected to centrifugal

force, causes the oil to flow outward.

6-9. Removal

Refer to paragraph 2-6 for removal procedure. Note

number of shims on converter pilot.

6-10. Inspection and Repair

a. Inspect converter for excessive wear, warping,

cracks, or other damage.

b. Since the torque converter is a welded assembly,

it must be replaced as a unit as authorized.

6-11. Installation Checks

The following checks should be made when installing

Figure 6-9. Checking converter tang depth.

a. Tang Depth.

(1) Install converter on flywheel with no shims on pilot.

(2) Place scale across tangs of converter and another

scale from flywheel housing face to-first scale (fig. 6-9).
