INSTALLATION INSTRUCTIONS for JM601 BombProof™ MOTOR MOUNTS
P.S.
Please read and understand all instructions before beginning the installation of these motor mounts. Please read
the terms and policies on the back of these instructions.
The JM601 motor mounts are designed to fit the following Jeep® vehicles: 1987 -1990 YJ Wranglers equipped
with 4-cylinder engines (2.5L) . A increase in engine vibrations will be noticed with the 2.5 L
D.S.
engines!
STEP 1: With the Jeep® on flat level ground, apply the parking brake, block the tires so it cannot move.
Put the transmission in neutral. Using a jack, place a block of wood between the jack and the oil pan. Apply a
slight amount of pressure on the oil pan , Be careful not to jack the engine to high or you may break the radiator
shroud.
STEP 2: Remove the drivers side stock motor mount. Save the hardware that you removed because it
will be re-used. Install the BombProof™ motor mount in it’s place. Do not tighten any of the nuts or bolts at this
time. If your vehicle has a aftermarket suspension lift kit that uses spacers between the skid plate and frame to
lower the transfer case, this can cause the motor mounts to be slightly out of alignment. If you have trouble lining
-up the thru-bolt, it may be necessary to temporarily un-bolt the transmission mount from the skid plate and raise
the transmission up slightly until the thru-bolt lines up.
STEP 3: Remove the stock motor mount from the passenger side of the engine. Install the BombProof™
motor mount in it’s place . Re-use the stock hardware. Do not tighten the nuts or bolts yet. If you had un-bolted
the transmission mount from the skid plate in step 2, you can now lower it back into place and tighten the bolts
that you removed.
STEP 4: Tighten the bolts and nuts on the bottom of the BombProof™ motor mounts to factory specs.
Tighten the thru-bolts on the engine mounting “fork” to factory specs. Remove the floor jack. Check all of the
hardware for proper torque specs after 50 miles and every off -road use. Thank you for purchasing your BombProof™ motor mounts from M.O.R.E.™.

TERMS-POLICIES:
FIT and TOLERANCES: These Motor Mounts are the results of countless hours of research, testing, fitting and refining.
Jeep® frames have a wide tolerance on bolt hole centers from frame to frame. This is why M.O.R.E.™ has installed “slots” in
which to mount them. In addition to the factory tolerances, most people install other then factory equipment such as suspension lift kits, skid plates, different transfer cases etc. M.O.R.E.™ has done the best job we can to insure that our parts fit with
all of the possibilities. However, you may find it necessary to grind, elongate, bend, or force these parts to fit on your rig.
