I need to replace the motor mounts on an '83 300SD. There is precious little
on a "Google" search on this topic and conflicting information on Google and
my Haynes manual. Apparently the right and left side is different and
jacking up the motor (I do not have a hoist in my garage) is not clearly
defined. (Use a block of wood under the oil pan and DON'T use a block of
wood under the oil -pan) Have any of you done this and can you give me the
benefit of your experience and any special tools I should be aware of and
situations to avoid. Should I change the shocks while I am there since it
looks like they have to come off too? Thanks for any help and information in
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
more than 3 - 4". Slide in the new mounts.
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
