Default Replace Motor Mount (INSTRUCTIONS)


REMOVE/REPLACE FRONT ENGINE MOUNT (MOTOR MOUNT) (These are the steps that I took with the tools and equipment that I had available)

-- Lift the bike with the Craftsman red MC/ATV lift or other suitable lifting device. I lifted mine all the way to the top limits of the lift.
-- Secure the bike to the lift with straps. Since the bike is at the top lift limits of the jack, this is very important.-- Remove the voltage regulator by removing the two 7/16 nuts, one on each side, and let it hang from the attached wires. It is not necessary to completely remove the voltage regulator from the bike.

-- Remove the two bolts/washers/nuts from the flange of the motor mount. The bolt is 9/16 and the nut is 11/16. This is usually removable with a standard ratchet and box end wrench. No impact (air) tools are necessary.

-- Remove the bolt in the center of the motor mount. The bolt is 9/16 and the nut is 11/16. Notice the position of the big washer on the underside of the mount.

-- With the motor mount completely free of attaching bolts, lower the bike on the lift all the way down.
-- Remove the lift from the bike and then re-position the lift as far back on the underside frame of the bike as possible. You will actually have the let one arm of the lift make slight contact with the transmission/rear end area of the bike. Not to worry.

-- Lift the bike to just upright and level. The front wheel should be slightly off the floor, 1 inch clearance, or so, and the rear wheel touching the floor.

-- Secure the bike to the lift with straps. Be sure to secure the front of the bike as well as the rear area of the bike. Take one strap and position at the front of the fuel tank area between the fuel tank and the front forks. This is the area where the main frame becomes the neck of the bike at the front forks.

-- Cut a block of 2X4 wood to approximately 8 inches long.-- Get your scissors jack from your automobile. This is the jack that comes with most cars. A small bottle jack may work as well.-- Position the scissors (car) jack as close to the front of the motorcycle (mc) jack as you can. So looking at the bike from the left hand side. You will see: back tire, mc jack, car jack, front tire.

-- Take the block of 2X4 and place on the top of the car jack. The top is the part of the car jack that actually touches the item being lifted. The block of wood will eliminate scarring of your engine underside and provide a more stable lifting method.

-- Slowly lift the car jack until it makes contact with the underside of the engine. Continue to lift the car jack until the engine begins to lift off the motor mount. The engine will lift approximately 1 inch off the mount. Pay close attention that the bike is not moving on the mc jack or that the car jack is not trying to lift the bike. The only thing that should move is the engine.

-- Remove the two bolts, washers and nuts from the bracket that attached the motor mount to the engine. You will see the stabilizer turn-buckle attached to this bracket. The bolt and nut are 9/16 and are a bit aggravating to get too mainly because the bike is low to the floor.

-- The bracket should now be loose from the engine but still attached to the turn-buckle.-- Now you should be able to remove the old motor mount and replace it with the new one. Spray a bit of windex on the rubber portion of the new motor mount. This makes it even easier to put it in place.

-- Attach the new motor mount by replacin

How do you tell if the motor mount is broken?

Thanks for the detailed instructions. I, myself, don't need it at this time, rither. But nice to know it is here if I do. How long will this post stay on the forum, if I need to search for it later? Just curious.
