Check the motor mounts, as they collapse the exhaust will contact the
chassis and make a lot of noise..

Subject: [MBZ] After Action Report - '87 300TD accessory belt
tensionerreplacement
Dieselvolk,
Finished the job last night, and I am VERY pleased with the reduction in
noise from the engine bay. I'd read about others reporting such happy
news,
I'm glad to add my name to that list. I have known this needed
replacement
for the last 10k miles or so, and ordered the part about two years ago
from
BuyMBparts.COM way back then. The pulley wheel was just out of the plane
of
the rest of the pulleys and the belt, and by carefully pushing on the
lever
with a stick I could make a change to the engine's noise at idle.
However,
recently the car developed some really nasty noises at around 900 RPM that
I
was convinced were due to a loose exhaust bit or some other piece of the
motor that was loose.
I'd also order the 8mm stubby hex in socket form 'special tool' for R/R
the
viscous fan clutch. It is too stubby in my opinion for loosening the
screw, but just fine for applying 45 Nm of torque. I needed a strap
wrench
to hold the pulley still for the R/R of the fan clutch.
In addition to the lack of a 12mm hex, there was one other problem. The
new
tensioner did not come with an end cap, so I'll need to order one of
those.
Rather irritating that the cap didn't come with it. I fashioned a
temporary
cover from a piece of Tyvek-like material and a zip tie; that should keep
the road grime out of the pivot bearing workings until a new cap arrives.
Very respectfully,
/s/
