.
(e) Remove the two bolts and the 856A2717 ADAPTER-LOCK CORE ENGINE (856A2717G01) from the handcranking drive pad.
(f) Install the handcranking drive cover (Ref. AMM TASK 72-63-00-400-002), but do the HJ9 and HJ10 harness connections at the end of this procedure and do not do the tests.
(3) Install the control alternator (30) as follows:
(a) Install the 856A2953 GUIDE PINS STATOR ALTERNATOR (856A2953G01) in the three bolt holes in the attachment pad.
(b) Remove the protective covers and closures from the control alternator (30).
(c) Lightly lubricate the new AIPC 73-21-30-01-040 O-RING (210) with engine oil (Material No.CP2442) .
(d) Install the new O-ring (210) in the recess on the attachment pad.
(e) Install the control alternator (30) over the rotor (140) until the alternator seats on the attachment pad.
(f) Remove the guide pins from the attachment pad.
(g) Install the three bolts (180) and three washers (130) through the alternator into the attachment pad.
(h) TORQUE the bolts (180) to between 65 and 60 lbf.in (0.73 and 0.68 m.daN )
