Mountain Off Road 7686-4 - Manual (Page 5)

STEP 8: Depending on your springs you may be able to now set the shackle angle at 60 degrees with
the springs hanging ( No Weight ) and everything will be fine, See Figure 11 . We suggest that you do
this as a starting point but once the hanger has been clamped to the frame at the 60 degree angle you
then apply weight to the springs. The shackle angle should be straight up and down 90 degrees, see
figure 12 , If it is not 90 degrees than move the bracket “P” forward or back until the correct angle is
achieved.
STEP 9:
Find the exact center of the slotted holes, and punch a mark. SEE FIGURE 13 & 14. This
must be done as accurately as possible, in the inside and outside of the frame rails, drivers and pas-
senger side. Center punch the lower “lock mounting bolt” hole at this time as well. SEE FIGURE 15.
Remove items “P” from the frame. With a 1/8” drill bit in a angle head drill, bore a pilot hole through
the center punched marks, all locations. SEE FIGURES 16 . Now, with a 1/2” bit in a power drill,
enlarge the pilot holes ON THE SIDES OF THE FRAME ONLY to 1/2”. Do not drill the underside lock
mounting bolt holes at this time!!! Drill from the outside toward the inside using the inside pilot hole to
keep the bit lined up. Enlarge the OUTSIDE HOLES ONLY to 3/4”. SEE FIGURE 17. Chamfer any
burrs that maybe present.
STEP 10:
Now, enlarge the underside “lock mounting bolt” holes to 21/64”. Tap these drilled holes
with a 3/8” x 24 (fine thread) tap. Use cutting oil and tap slowly and carefully. Make sure the tap is
straight and true when going up through the hole. SEE FIGURE 18.
STEP 11:
Insert items “Q” into the 3/4” holes you just drilled. SEE FIGURE 19. Be care full not to
drop them into the boxed frame!
STEP 12:
Re-install items “P” on the frame over items “Q”. Grab all four items “R” and install one
item “T” over each, and install “R” through item “P” and “Q”. Then in the inside of the frame install an-
other item “T” over the threads of item “R” and one item “S” on each. Re-check the angle, and if cor-
rect, tighten items “R” & “S” to 55 Lb. Ft. torque SEE FIGURE 20.
STEP 13:
Install items “W & V” over items “U” and thread items into the tapped holes. Tighten
them to 10 Lb. Ft. torque. Install your shackles to your springs and to items “P”. SEE FIGURE 21.
Use thread locking compound on the threads or, new locking nuts on your bolts. Do not tighten at this
time. Install the U-bolts and plates and torque them to factory specs. Install the wheels and tighten
the lug nuts to factory specs. Remove the jack stands. Jump up and down several times on the front
bumper to “seat” the springs. Tighten items “I” & “J” to 30 lb. ft. torque. Tighten your stock shackle
bolts to 10 Lb. Ft. torque.
STEP 14:
Test drive the Jeep® . Chances are the steering wheel may not be centered. You can
adjust the drag link to center it. Installing this shackle reversal system will not affect the alignment
(camber or toe-in), so having the Jeep® aligned is not necessary. The caster will increase slightly,
however it is a non-tire wearing angle. Go back and check all of your work and make sure everything
is done properly. Check the brake lines and make sure that they are not being stretched to far.
STEP 15: Your drive shaft will need to have a long travel slip yoke installed to work properly with
this system. Call Tom Wood’s Custom Drive Shafts at: 877-497-4238. DO NOT TRY TO SHORT CUT
THIS STEP OR DAMAGE COULD OCCUR TO YOUR DRIVE TRAIN!!!
You are finished! Be sure to re-check all hardware for tightness after 100 miles. If you have any questions,
please call. Thank you for purchasing this product from M.O.R.E.™ Keep on Jeepin’.
