E. Prepare to Install the Solenoid
S 424-040-N00
(1)
If it is necessary to install a new solenoid, do the steps that follow:
(a)
Remove the protection covers from all openings in the solenoid.
(b)
Lubricate the two adapters, which are installed in the top of the solenoid, with engine oil.
(c)
Install the two adapters with the gaskets into the openings on the top of the solenoid. 1) Tighten the two adapters to 65-75 pound-inches (7.3-8.5
newton-meters).
(d)
Lubricate the threads of the caps, which are installed on the adapters, with engine oil.
(e)
Install the caps to the adapters. 1) Hold the adapters and tighten the caps to 90-100 pound-inches (10.2-11.3 newton-meters).
2) Safety the caps with lockwire or safety cable and safety cable ferrule.
(f)
Lubricate the threads of the three remaining adapters with engine oil.
(g)
Install the larger adapter with the gasket in the center of the solenoid.
(h)
Install the remaining two adapters with the gaskets in the outer ports.
(i)
Tighten the center adapter to 150-170 pound-inches (16.9-19.2 newton-meters).
(j)
Tighten the outer adapters to 110-120 pound-inches (12.4-13.6 newton-meters).
F.
Procedure
S 424-041-N00
(1) Install the solenoid:
(a)
Remove the protection covers from all open line ends.
(b)
Put the solenoid in position on the intermediate case with the two capped adapters on the top.
NOTE: The mounting lug of the solenoid must be to the rear of
____ the lugs on the intermediate case.
(c)
Lubricate the threads of the bolts, which attach the solenoid, with engine oil.
