AERO 7500 ASSEMBLY
1.
Over time, you may need to disassemble your TITAN Aero 7500 for service or to replace components. Use the
following steps to put the actuator back together, checking this manual's assembly diagram and parts list for
reference.
2.
Set the coupler case <2> on its left side so that its bottom is facing you. Set the ball catch casting <32> on its flat
side with the spring pocket facing up. Place the ball latch torsion spring <33> in the pocket with the bent spring
leg below the casting hole, and pointing up. Slide the casting and spring into the coupler behind the ball socket,
lining up the holes. Check that the spring leg is located in the notch of the strut welded to the coupler. Push a 1/2
inch diameter damper pin <5> through the coupler case, spring, and casting. Check to see that the sub-assembly
is operating properly by rotating the ball latch casting against the spring pressure. The casting should return to the
closed position when released.
3.
Set the coupler up-side down. Fix the small end of the damper <4> to the coupler case <3> with the 1/2" damper
pin <5>.
4.
Fit the lockout lever torsion spring <41> over the ball latch pin <5> on the right side, with the coupler case facing
you. The long leg of the spring points to the center of the coupler case, and the short leg faces out. See Figure 6.
Place the lockout lever <40> over the ball latch pin so that the short leg of the ball latch torsion spring <41> is
hooked in the kidney shaped hole of the lockout lever. The lockout lever <40> should want to rotate down by both
the force of gravity and the lockout torsion spring <41 >. Using your hands, hold the lockout lever <40> to the side
of the coupler case assembly <3> and slide the assembly into the outer case. Lay the front roller <24> in the rear
of the coupler case assembly <3> and allow it to roll forward into position. Locate the torsion handle spring <37>
as shown in Figure 7, and temporarily lock it into position using the 1/4 inch diameter handle groove pin <35> (to
avoid later inconvenience, do not neglect this step). Do not attach the retaining ring to the pin at this time. Insert a
1/2 inch diameter bolt <25> through the front hole in the outer case, through the coupler case assembly, and
through the front roller. Secure the ½ inch bolt <25>, with a flat washer <27> and a ½ inch lock nut.
5.
Rotate the actuator again so that it is laying up-side down. Place a block (roughly the size of a 2 inch by 4 inch
section of lumber) under both ends of actuator to ease assembly. Slide the ½ inch bolt <25> through the second
side hole from the front of the outer case, into the coupler case, and into one of the sintered iron rollers <23>.
Note the beveled side of the rollers should face out towards the outer case sides. Position the roller separator
<29> and slide the ½ inch bolt <25> though the holes of the separator. The separator needs to be positioned so
the middle portion of the "U" is on the bottom, flush with the inner coupler. Continue sliding the ½ inch bolt <25>
through the second rear roller, and finally through the outer case. Secure it with a ½ inch washer <27> and a ½
inch lock nut <26>.
