Re: [MBZ] Serpentine Belt Lower Pivot - Need Help!
I did it to Gump. It was a bear, and not to be done twice on purpose. It took most of the day, nowhere near 12 hours though. I might have prepped the area prior to getting it near the shop, and once done, gone back home to install all the stuff I had removed for safe keeping. On Friday, May 26, 2006, at 07:04 PM, Kaleb C.

[MBZ] Serpentine Belt Lower Pivot - Need Help!
Help!
I rec'd my Bentley manual and noticed the warning about the tensioner
becoming worn and out of alugnment - checked my '91 300D 2.5 this am and
discovered 1/4 play. I'm ordering all new stuff from Rusty - but I need to
know if it's safe to drive like this as I expect the parts won't arrive
until next tuesday. -
2 questions -
1st - Should I park it 'til I fix it? (my wife would drive it today, Sat
Sun to work - 100 mi RT each day - unless ya'll say it's too dangerous.)
2nd -- where the H do I find the engine #? I've looked all over but
evidently not the right place. As I mentioned - it;s a '91, W124 5 cyl 2.5
Turbo.
Thanks guys - I know I can count on ya'll!

That is a good question- I've been wondering about mine too. I have at
least 1/4 inch play on mine with slight noise at startup for about 10
minutes. How can we tell when the tensioner pully or spring etc. are
failing? Watch for wobble in the pully?

Hi John!
Hope you're doing well. Do you know how long your tensioner has had the
play you mention in it? Since I just bought my 300 in Feb I'm not sure if
mine has been like this for 12 weeks or 12 months.

I've looked all over but evidently not the right place. As I mentioned - it;s a '91, W124 5 cyl 2.5 Turbo. It is unlikely to fail until there is considerable noise from the area (and you have driven it a lot and it hasn't failed YET), but if the idler is more than a few degrees out of parallel with the length of belt above it, I wouldn't be taking any long trips. Be sure you have a 12 mm allen hex key/socket that will fit the lever. I'd also order new plastic front covers for the idler and tensioner lever to keep dirt out. In my experience, the belt/tensioner/shock/idler assembly require attention about every 75kmi, but not every piece needs to be replaced every time. The shock absorber seems to be the shortest lived element. The original equipment ones seem to last about 75-80kmi while the aftermarket ones seem to fail at more like half that interval (but they cost less too).

Thanks John,
I ordered the rest of the parts needed to fix it from Rusty this morning -
along with the stuff I ordered last week it looks like around $175 total for
the spring, damper, lower pivot, upper pivot and damper.
Not sure how much disassembly I'll need to do to get to everything but I've
removed the shroud fan before so that'll be easy. Just not sure what
damage has been done by the lower tension adjuster getting cockeyed.
Hopefully the damage will be minor and limited to the tensioner and not
where it attaches to the engine.
Time to study the manual and plan my attack ;-)
Thanks for the info you provided -

If you don't use it this time you will the next time. If there is ANY deviation from parallel between the belt and the idler, either the idler or the lever OR BOTH) require replacement. If the play become extreme, the fan blade can hit the idler and if it does it can shatter taking the radiator, ATF and oil hoses with it and that CAN destroy the engine. Even if it doesn't destroy the engine, it's an expensive repair! Inspect the location of the idler with respect to the belt every time you open the hood and expect to service the tensioner system about every 75kmi (or sooner if you use aftermarket shocks). Replace the belt if there are ANY cracks on the ribbed side. I get 50-100kmi from belts (and always keep an old belt as a spare for emergency - the belt can be hard to find when you need one on a Saturday or Sunday - even some dealers don't stock them).

Re: [MBZ] Serpentine Belt Lower Pivot - Need Help!
David asked:is checking on the smooth side

Hi David -
I think you need to look carefully at the underside of the belt - there's a
place where a pulley reverses the direction of the belt and exposes the
underside (on my W124 diesel it's next to the power steering reservoir) IMO,
the underside if the best indication of the condition of the belt. BTW, the
belt is inexpensive (less than $20 for W124 300D's) and installing it is
pretty easy.
If there's any question about the condition of the existing belt it's false
economy not to go ahead and change it (IMHO)--
Sincerely,

Or should I replace a belt that shows this kind of wear? The ribbed side of the belt is clearly visible where it loops over the idler while where the belt loops over the PS pump pulley and then descends to the AC compressor, the ribbed surface is somewhat obscured. If there are any threads dangling at the side or the side of the belt seems to be frayed, I'd change the belt too. I think you misunderstood my question, due to poor word choice on my part. By checking I meant fine, shallow cracks that form a sort of irregular checked pattern on the surface. On one of my cars I have a serpentine belt that has that kind of wear on the smooth side, but the ribbed side still looks good. I'm wondering if I should change it.
Re: [MBZ] Serpentine Belt Lower Pivot - Need Help!
As usual, Marshall calls the truth without even looking at the car. An inspection of my idler shock reveals that it is spoiled (spins around, can't be tightened.) It is the source of the sound. I bought a shock and idler (to keep in the trunk with allen wrench) for future. Still haven't touched the wretched shutoff valve. AS a test, I plugged in the vacuum line to the new shutoff valve and watched from inside the car as I turned the key off. The new valve closes all the way. TIME to pull the old one out? Oh po.

I'm ordering all new stuff from Rusty - but I need to know if it's safe to drive like this as I expect the parts won't arrive until next tuesday. - 2 questions - 1st - Should I park it 'til I fix it?

I've looked all over but evidently not the right place. As I mentioned - it;s a '91, W124 5 cyl 2.5 Turbo. It is unlikely to fail until there is considerable noise from the area (and you have driven it a lot and it hasn't failed YET), but if the idler is more than a few degrees out of parallel with the length of belt above it, I wouldn't be taking any long trips. Be sure you have a 12 mm allen hex key/socket that will fit the lever. I'd also order new plastic front covers for the idler and tensioner lever to keep dirt out. In my experience, the belt/tensioner/shock/idler assembly require attention about every 75kmi, but not every piece needs to be replaced every time. The shock absorber seems to be the shortest lived element. The original equipment ones seem to last about 75-80kmi while the aftermarket ones seem to fail at more like half that interval (but they cost less too).

I've never seen that pattern on any of the 15-20+ belts I've had on my cars. If the belt seem pliable and supple I expect I'd go with it (but ALWAYS carry a spare belt). I change the belt whenever I do work on the tensioner (unless it's been very recently changed) and keep the best of the old belts as spares. These belts seldom fail without clear visible and audible warning well before they actually do fail, but you do need to pay attention. If the belt makes noise FIND OUT WHY and fix it!
