Lincoln AL3Z-6068-B Engine Support Insulator Assembly

There are three powertrain mounts on the vehicles; left and right engine mounts attached to the engine block and frame, and a rear mount attached to the transmission and frame. Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage or wear on driveline components. During the check, the engine must be raised slightly to remove the weight from the mounts. Raise the vehicle and support it securely on jackstands, then position a jack under the engine oil pan with a large wood block between the jack head and the oil pan, carefully raising the engine just enough to take the weight off the mounts. Check for relative movement between the inner and outer portions of the mount using a large screwdriver or prybar; if movement is noted, lower the engine and tighten the mount fasteners. Inspect the mounts for cracked, hardened, or separated rubber, indicating a need for replacement, and apply rubber preservative to slow deterioration. Disconnect the cable from the negative terminal of the battery, remove the engine cooling fan and shroud, and raise the front of the vehicle securely on jackstands. Support the engine with a lifting device from above, ensuring not to connect it to the intake manifold, and raise the engine just enough to relieve the weight on the engine mounts. For 2WD models, remove the engine mount-to-frame support bracket through-bolt, then the mount-to-engine block bolts, and remove the mount and heat shield if equipped. Place the heat shield and new mount in position, install and tighten the mount-to-engine block bolts securely. For 4WD models, remove the engine skidplate, support the front axle with a floor jack and jackstands, and lower the front axle for additional clearance. Remove the front crossmember and the bolts attaching the front axle to the frame, then remove the engine mount-to-frame support bracket through-bolt and the engine mount to engine support bracket bolt and nuts. Install the new engine mount onto the engine support bracket and tighten the bolts securely. After installing the engine mounts onto the engine, lower the engine while guiding the engine mount and through-bolt into the frame support bracket, then install and tighten the through-bolt nut securely. The remainder of the installation follows the reverse order of removal, after which the engine hoist and jackstands can be removed, and the vehicle lowered.

There are three powertrain mounts on the vehicles; left and right engine mounts, bonded to the engine block and the frame, and the rear mount connected to the transmission and the transmission crossmember. Engine mounts do not usually need service but when you have a damaged or worn out mount, you should replace it before it spoils or damages other parts of the driveline. During the check the engine must be lifted up, so that the weight would not lie on the mounts. First of all, a car should be lifted and safely secured on the jackstands. Place a jack under the engine oil pan, and put a large wooden plank on the head of the jack, slowly lift the engine just enough to minimise pressure on the mounts. Next using the large screwdriver or prybar try to move the inside and outside of the mount relative to each other; if motion is obtained, lower the engine and tighten the mount screws. This test involves checking the mounts for signs of cracking, hardening or where the rubber has separated from the metal in which case then we replace the gave mounts. Remove the multi metre cable connection from the negative terminal of the battery, next, lift the front part of the car and place it on jack stands. Exploding the side of the engine where carburetor is located Disconnect the hood and the intake manifold. For 3.5L models only, disconnect high-pressure fuel pump, two nuts of charge air cooler's tube bracket and free the hose clipped on the valve cover side. First take off the cowl panel, then the air deflector over the radiator and the under vehicle splash shield. Most of the nuts that hold the transmission mount crossmember needs to be loosened but not fully removed. It is necessary to fasten lifting eyes at the right-front and left-rear of the engine and use a crane or engine support fixture to lift it. For 4 WD models raise front axle slightly and support front differential reinstall floor jack under front differential ensuring that the differential is firmly held to the jack, remove differential mounting bushing bolts when the differential is to be lowered to gain access to the engine mounts. First take out the through-bolt of the engine mount and then the bracket to engine block bolts and finally the bracket. Loosen the three bolts which holds the mount insulator to frame rail. Bolt in the new engine mount using the recommended torque value. Slide the engine mount onto the engine support bracket and tighten the bolts then insert the through-bolt of the mount and apply means of preventing the thread from backing out. The rest of the operation is done step by step in the reverse sequence to the removal that concludes with the removal of the engine hoist and jackstands before lowering the vehicle.

Insert a large screwdriver or prybar into the space between the transmission and the crossmember and try to pry the transmission up to check the transmission mount; if the transmission is easily moved, closely examine the rubber insulator part of the mount for tears or cracks, indicating it must be replaced. If there is any separation of the rubber, the mount is worn out. Remove the nuts attaching the mount to the crossmember, then raise the transmission with a floor jack until the mount studs clear the crossmember, and remove the bolts attaching the mount to the transmission. After removing the mount, installation is the reverse of the removal procedure, ensuring to tighten the nuts and bolts to the specified torque.
