B. Aircraft Maintenance Configuration
(1)
Disconnect the isolation coupling of the PTU (Ref. TASK 29-23-00-860-001).
(2)
Depressurize the Green and the Yellow hydraulic systems (Ref. TASK 29-10-00-864-001), (Ref. TASK 29-10-00-864-002).
(3)

Subtask 32-11-11-869-060
C. Flight Configuration Precautions
(1)
If the electrical power is not necessary for other maintenance tasks, de-energize the aircraft electrical circuits (Ref. TASK 24-41-00-862-002). Then it is not necessary to operate the LGCIU circuit breakers.
(2)
If the electrical power is necessary, do the precautions for flight configuration (Ref. TASK 32-00-00-860-001) before you open the circuit breakers.

A. Detailed Inspection of Forward Pintle Pin Lock Bolt Installation
(1)
Examine the forward pintle pin and make sure that:
-
the lockbolt (1) is not missing
-
the sealant on the head of the lockbolt (1) is not cracked or broken. Cracked or broken sealant shows that movement of the lockbolt (1) has occurred.
(2)
If the lockbolt (1) is missing, do the detailed visual inspection of the forward pintle pin and spherical bearing at Para 4.C.
(3)
If the lockbolt (1) is in position but the sealant is cracked or broken, do the detailed visual inspection of the lockbolt at Para
4.B.
(4)
If the lockbolt (1) is in position and the sealant is not cracked or broken, lubricate the spherical bearing (18) through the greasers
(17) (Ref. TASK 12-22-32-640-001).
