T.  Install engine removal/installation hoist equipment (Fig. 405). Perform the following:
(1)  
Remove access panels covering the three engine hoist receptacles.

(2)  
On engine hoist receptacles with spring torsion feature, manually insert loadcell assembly into their respective engine hoist receptacles, push upward, and allow indicating systems to rotate by spring torsion 60 degrees clockwise to lock position, and pull down to ensure seating (Fig. 405). Repeat for each loadcell assembly being installed. On engine hoist receptacles without spring torsion feature, manually insert loadcell assembly into their respective engine hoist receptacles, push upward, turn indicating systems 60 degrees, and pull down to ensure seating (Fig. 405). Repeat for each loadcell assembly being installed.

WARNING:  TO PREVENT INJURY TO PERSONNEL OR DAMAGE TO EQUIPMENT DUE TO A LOADCELL ASSEMBLY SLIPPING OUT OF ENGINE HOIST RECEPTACLE, MANUALLY ENSURE THAT EACH IS IN LOCKED POSITION. WHEN CORRECTLY INSTALLED, THE LOADCELL ASSEMBLY WILL NOT ROTATE WITHOUT BEING PUSHED UPWARD INTO RECEPTACLE.

(3)  
Check that inboard forward, inboard aft and outboard loadcell assemblies are in their proper locations.

(4)  
Install F80219-( ) hoist assemblies to their respective loadcell assemblies by inserting the ball lockpins.

(5)  
On system, with painted engine hoist receptacle (SB 57-1117); and tooling (F80219-47,  -48 and -69) with lock collar and painted alignment stripe, perform the following:

(a)  Using hand pressure only, insert loadcell assembly into receptacle and allow loadcell assembly to rotate by spring torsion 60 degrees clockwise, so that paint stripes on receptacle align with paint stripes on loadcell assembly (view 1). Pull down into locked position and install lock collar (view 2) to disallow upward motion of loadcell assembly and subsequent possible disengagement.
WARNING:  TO PREVENT INJURY TO PERSONNEL OR DAMAGE TO EQUIPMENT DUE TO LOADCELL ASSEMBLY DISENGAGEMENT, ENSURE THAT LOADCELL ASSEMBLY IS IN LOCKED POSITION. WHEN CORRECTLY INSTALLED IN THE LOCKED POSITION, THE FOLLOWING CONDITIONS APPLY: 1) THE INDEX MARKS ON THE RECEPTACLE WILL LINE UP
WITH THOSE ON THE LOAD CELL ASSEMBLY.
2)  THE LOCK COLLAR WILL PREVENT THE LOAD CELL ASSEMBLY FROM BEING PUSHED UPWARD INTO THE RECEPTACLE.
3)  THE LOAD CELL ASSEMBLY WILL NOT ROTATE.

When using F80219-45, -46 and -68, check that fingers of keepers in engine hoist receptacle are visible after installation of loadcell assembly. If fingers of keepers are not fully visible, loadcell assembly is not seated and locked; reinstall per step (2).
WARNING:  MANUALLY INSTALL LOADCELL ASSEMBLY INTO ENGINE HOIST RECEPTACLE. ON ENGINE HOIST RECEPTACLE WITH SPRING TORSION FEATURE, USE OF HAND OR POWER TOOLS COULD APPLY AN EXCESSIVE FORCE IN AN UPWARD OR ROTATING MANNER WHICH WOULD DAMAGE THE ROLL PIN STOPS OR TORSION SPRING IN THE ENGINE HOIST RECEPTACLE. DAMAGED ENGINE HOIST RECEPTACLE WOULD PREVENT PROPER SEATING OF LOADCELL ASSEMBLY.
WARNING:  DO NOT PUSH UPWARDS TO CHECK IF LOADCELL ASSEMBLY IS SEATED. UNSEATING MAY OCCUR.
