300SD motor mounts

Have a little experience with the 123 and 126. You didn't mention the year. You will need a hoist. There are three points on the top of the engine for lifting. Loosen the transmission (check the clutch while you're at it), loosen anything else that may have a problem being moved more than 3 - 4". Slide in the new mounts.

It is an 1983 300SD.. wolf

On a 126 there right and left mount have different part numbers. I got a "engine hoist" and metric hexagonal Allen sockets ( you need 8 and 6 mm socket). I replaced the small hydraulic dampers and holders too. Undo the throttle linkage by removing the clip and pushing back toward the fire wall. I did not touch the air filter. Be aware of the radiator and fan as you lift the engine. First remove the single large screw form the bottom of the mount then remove the 2 (6mm) screws on top of the mount (I have to lift and tilt the engine to get at the medial screw.. just hoist up on a diagonal one side at a time.I used a cut off seat belt and tied it into the loops provided on the front and back of the engine.) Replace the parts and screw down the medial 6mm screw first since you cannot get at it once you drop the engine again. All in all pretty easy job. wolf
