Torque control disassembly procedure
If air motor has been operating properly, do not remove it from
torque control section at this time, but proceed as outlined. The
steps to be followed have been grouped. Steps within a group may
be performed in any sequence. The groups, however, cannot and
must not be per-formed out of sequence. All steps within a group
must be completed before proceeding to the following group. Refer
to assembly drawing on Page 11.

When failure is due to a malfunction of torque control unit,
the failing parts, usually, can be found easily by observing
operations of the various pawis and latch. This can be done
by holding subassembly in the hand and applying torque or
turning force to internal gear (Pc #10) within reaction mem-
ber (Pc #26). See Trouble Shooting Chart.
