Belt noisey

[SilverSaloon]

My 1995 E300D saloon has had a noisey belt since we got it. it makes a tappy noise all time time which is not noticable on my estate 124.

it seems to be coming from around the pully attached to the power steering resesvior.

any tips or hints on what can be done? is this belt relatively easy to work on/replace/tighten etc?

It's probably the tensioner pulley bearing. You could remove it and soak it in oil to flush it out, failing that replace it.
The tension is automatically adjusted by the spring.

It just fits in a tuna tin nicely.. Note how black the oil becomes and the bits in it.

how easy is the bearing to remove? do i have to remove the belt 1st or is it something i can take off witht he belt in situ?

These are a common failure - they wear and then get noisy. Before I replaced mine I thought it was the top end of the engine getting "old" and tired! That was at about 150k on a e300d. Replace the tensioner and shock absorber - and hey presto - back to quiet and smooth tick over - just like new (almost). I was really chuffed - well worth replacing rather than trying to clean out.

Belt off, then undo the centre allen bolt.
