=== Replacing Motor Mounts === Usually motor mounts do not require the engine to be removed from the vehicle, but in some cases the lack of clearance requires it. Besides lifting the engine up, the vehicle may also need to be raised to allow parts to be disconnected and reconnected. In some cases, radiator shrouds, exhaust manifolds, fuel and water lines, linkages, etc. may have to be loosened or removed. There are times that engines have to be removed to replace mounts, but this is rare. Always replace mounts in pairs. Even though the other looks good, you have the equipment available and spending the time now is better. Also look at replacing the rear trans mount, especially if they are OEM equipment. In some cases, mounts may come as a complete kit for your application. [[Image:Eng_-_trans_mount_kit.jpg ]] #Gather all equipment together to do the job. This includes engine lift, roller jacks, jack stands, drain pans, speciality tools, wood blocking and planks. #Find a level surface, block rear wheels and jack up the front of vehicle to a level which allows you a safe access under the vehicle. Block up the vehicle using jack stands under the frame. #Place engine lift at front. Remove air cleaners, fan shrouds, and battery cables. Loosen or remove exhaust pipes, water and fuel lines if necessary and drain them. Install lifting chain or lifting plate to engine block, do an initial lift to engine and then inspect. #Check for electrical wires, lines and hoses that are pulled. Check for clearance between engine and firewall, and transmission and floor pans. Check for rad to fan clearance. Check steering shaft to manifold clearance. #Continue raising engine to a suitable working and mount removal height. Remove thru-bolts from both mounts. Make engine stable using jack stands, wood blocking and planks. Wiggle engine around to simulate working on it. REMEMBER: YOUR FINGERS WILL BE IN CLOSE PROXIMITY TO THE FRAME AND OTHER APPARATUS. #Remove mounts from engine and frame. Compare old parts to new replacements. Inspect for any damage to engine and frame. Chase out the threads in the block with a bottoming tap and use new grade 8 bolts and washers of the appropriate size. #Install new mounts. Apply lubrication to all bolt threads and tighten to specifications. Lower engine and align lower mounts, insert thru-bolts and tighten up hardware. Thrugh bolts are usually a knurled grade 8 type for maximum shear resistance. #Continue lowering engine and reassemble parts and equipment as required. Lower vehicle to ground after final inspection. '''Note:''' If replacing transmission mounts, raise transmission after loosening bolts and slide in new mounts, then finger tighten bolts before lowering vehicle. Tighten and torque down bolts. For added security use lock nuts or loctite to ensure that these bolts don't back out. [[Category:Engine]] [[Category:Transmission]]
