3) Raise the cable and place a roller under it allowing the cable to rest in the groves; then insert a 1/4-inch clevis pin
into the bottom hole at the angled end of housing A; next run it through the roller that you just positioned and out
the other side of the housing.
4) Slide TWO 1/4-inch flat washers onto the clevis pin; then, using the needle nose pliers, secure the clevis pin in
place with a 1/4-inch locking ring. You must use two flat washers on this clevis pin before inserting locking ring to
secure the clevis pin properly in place. Reverse the position of the two loose ends of the locking ring to lock
it securely in place. See figure 2 on page 5.
5) Make sure that both rollers spin freely and that the clevis pins remain stationary. You will want to double check
this after the cables are attached to the tailgate and you are operating the Gorilla-Lift™.
6) Repeat #1 through #5 to install the rollers on the other side.
STEP 4, ATTACHING THE CABLE TO THE TRAILER’S TAILGATE
See figure 4, figure 5, and figure 6 on page 6.
1. Lock your tailgate in upright position. Note: Quick-Links may be substituted for S-Hooks.
2. Attach an S-Hook to looped end of each cable. If S-Hooks are not available please refer to Step 4B on page 5.
3. Take all the slack out of each cable and using the S-Hooks attach each cable to the mesh on each side of the
tailgate as close to the side support angle/tube as possible. See figure 4 on page 6. (S-Hooks or Quick-Links
are for installation purposes only; NOT for permanent use!)
4. Slowly and carefully lower tailgate halfway down to the ground. Tailgate should remain stationary in this position
and move all the way up and down with very little effort. If not, return tailgate to upright position, secure it there
and make the following adjustments:
! If there is not enough lifting-power on the tailgate, keep raising the attachment point with the S-Hooks on
both sides of tailgate (keeping both attachment points the same height) until the tailgate remains
stationary at almost any position and moves up and down with very little effort.
! If there is too much lifting power on the tailgate and it will not go completely down or stay completely
down, please refer to troubleshooting #4.
5. Using a marker or punch make a mark on the tailgate side support tube/angle at the same height as the opening
in cable loop.
6. Drill a 1/2-inch hole through the gate’s side support angle/tube, where you made your mark.
7. Slide a 1/2-inch flat washer onto a 1/2-inch x 5 1/2-inch gate attachment bolt.
8. Slide the cable thimble onto the 1/2-inch x 5 1/2-inch gate attachment bolt.
9. Put one of the 1/2-inch flanged locking nuts, smooth end first, onto the 1/2-inch x 5 1/2-inch gate attachment bolt
and tighten the nut to the end of the threads. Then put one of the 1/2-inch flat washers onto the bolt.
10. Two people may be necessary for #10 and #11 if there is significant tension on the cables. Insert the gate
attachment bolt into the hole that you just drilled through the tailgate’s side support angle/tube.
11. Slide the other 1/2-inch flat washer onto the bolt. Then put on the other 1/2-inch flanged lock nut, flanged side
first, and tighten securely to the gate. The flanged locking side of the two nuts should now be in contact with the
two flat washers, sandwiching your tailgate’s side support angle/tube between them.
12. Repeat #5 through #11 on the other side of your tailgate.
The Gorilla-Lift™ should now hold most standard tailgates stationary at any position and travel up and down with
very little effort. If it does not, you need to increase or decrease the lifting-power by raising or lowering the
attachment points on your tailgate; see troubleshooting # 4. Never force the tailgate in either direction!
TROUBLESHOOTING:
1) If you are having trouble putting the locking rings on the clevis pins:
! Be sure you are using needle nose pliers, and as you push the ring on the pin gently rock it back and forth.
2) If a roller is not spinning freely:
! Check to see if the angled ends of your housing were bent during shipping; these ends must be straight. Check
to see if any burrs or rough spots were missed on inside of housing during manufacturing and smooth them down.
3) If your tailgate and/or equipment are rubbing against or hitting the locking rings and clevis pins:
! Change the direction of your pins to where the locking rings are on the opposite side of the housing.
