R (3) Install the O-ring (42) in the groove on the IDG splined shaft.
R (4) Install the O-ring (44) in the groove on the IDG (1) pilot diameter.
R (5) Put the IDG (1) on a HOIST - ACCESSORY, IDG R/I FOR CFM56-5 (TMHSD10-
R 20-00) or HOIST - ACCESSORY, IDG R/I FOR CFM56-5 (S387IDG).
R (6) Use the hoisting mechanism to align the IDG with the mounting pad
R support.
R Make sure that none of the weight is on the input shaft.
R (7) Turn the QAD tension bolt (43) to open the QAD ring (46). Align the
R mark on the QAD ring with the mark on the QAD engine-adapter plate.
R (8) Engage the lugs on the IDG in the openings in the QAD ring. To do
R this, align the " open-position " mark on the QAD with the opposite
R mark on the IDG.
R (9) TORQUE the QAD tension bolt to between 22 and 26 lbf.ft (2.98 and
R 3.52 m.daN).
R (10) Lightly hit the outer edge of the QAD adapter with a softface hammer.
R (11) Do a check of the tension bolt torque. The torque value must not
R decrease more than 2 lbf.ft (0.27 m.daN).
R (12) Do again the procedure until the torque on the tension bolt is
R between 22 and 26 lbf.ft (2.98 and 3.52 m.daN).
R (13) Do a check of the distance between the ring lug and bracket of the
R QAD ring and bracket. If the distance is less than 0.312 in. (7.9 mm)
R minimum,
R (Ref. Fig. 408/TASK 24-21-51-991-308)
R remove and replace the IDG (Ref. TASK 24-21-51-000-040) and the QAD
R adapter (Ref. TASK 24-21-41-000-040).
R (14) Safety the tension bolt with Lockwire CRS 0.032in. (0.8mm) dia
R (Material No. CP8002) (45).
R (15) Remove the HOIST - ACCESSORY, IDG R/I FOR CFM56-5 (S387IDG) or HOIST-
R ACCESSORY, IDG R/I FOR CFM56-5 (TMHSD10-20-00).

R D. Removal of the Protections
R (1) If necessary, remove the shipping plugs (19) and (18) from the oil-in
R and oil-out bosses, and retain for subsequent use.
R (2) Remove the protective covers from the oil-in (13) and oil-out (12)
R lines.

R E. Installation of the Unions
R (1) Install the new packing (17) on the union (16) and the new packing
R (15) on the union (14).
R (2) Install the union (16) and TORQUE it to between 30 and 40 lbf.ft
