CONVERTER.
a. Connect the torque converter to the drive
plate and torque capscrews to 15 ft.-lbs. (2.07
kg-m).
b. Adjust converter runout to .020 inch (.508
mm) maximum (refer to paragraph 7-12).

CHECKING RUNOUT (see figure 7-6).
a. Attach a dial indicator to the converter
housing with its point resting on the impeller
hub (pump drive sleeve).
b. Rotate the engine one full turn. The
indicator should register not more than .020
inch (508 mm) total variation (see figure 7-7).
c . If the indicator variation is substantially

splined to a clutch hub which splines to the
output shaft. The separator plates of polished
steel are splined to the clutch housings. When
a clutch pack is hydraulically locked up, power
flows through the input shaft, the clutch pack
housing, the separator plates and the friction
plates to the output shaft (see figure 7-9).
7-19. The clutch packs are splash lubricated.
Oil is splashed by the gears through holes in
the side of the clutch pack housings. This oil
escapes through holes in the housings.
