6-43. INSTALLATION OF MANIFOLD. (Refer to Figure 6-12.)
a. Lubricate and install the "O" rings (28) on the seven transfer tubes (27).
b. Insert the transfer tubes into the Power Pack body.
c.
Install the time-delay valve plunger (3) in the manifold. The plunger must move freely in the
manifold without binding.
d. Mate the manifold to the Power Pack body, using care to prevent damage to the "O" rings on the
transfer tubes. Align the dowel pin on the Power Pack with the dowel hole in the manifold.
NOTE
When installing the manifold, time the landing gear assembly to
the rack on the selector spool as shown in Figure 6-15. Refer to
the following steps if binding exists.
e. Install the four manifold attaching bolts (34) and washers (33). Torque the screws to 35
inch-pounds and safety. Do not over-torque the bolts, as this will cause binding in the movement of the
landing gear handle.
f. Lubricate and install the two "O" rings on the time-delay valve retainer. (Refer to Figure 6-10 or
6-11.)
g. Lubricate and insert the larger spring and spacer in the body through the reservoir.
h. Lubricate and insert the ball and smaller spring in the time-delay valve retainer (ball next to the
top of the retainer).
i. Lubricate threads on the time-delay valve retainer and install the retainer in the body through the
reservoir. Do not over tighten the time-delay valve retainer as this will cause the landing gear selector to
bind in the manifold. After tightening the time-delay valve retainer, check for freedom of movement of the
landing gear selector spool.
j. Thoroughly lubricate the handle return springs and plungers and install in the housing with the
hex-head retainers. Do not tighten the retainers at this time.
