Re: [MBZ] Growly and vibrating tandem pump 300TE......fixed
Looks like I owe Peter a cigar, it turned out to be the alternator pulley being off center, genius auto electrician used the old non springy spring washer to fasten the pulley. Came loose and wore an oblong hole in the pulley, the auto sparky re-tightened it but did not check that it was center, me being a trusting fool didn't check it either. Anyway all is fixed now and everything is quiet, for the time being.

Re: [MBZ] Growly and vibrating tandem pump 300TE
Anyway this makes me think that the pump is not the culprit, now it's onto the fan belt tensioner, although it is only a few months old, maybe try a new tensioner dampener, as it is pretty old. On the 60X I've had just about every part of that tensioning system go bad. Idler wheel, pivot, shock absorber, spring... And the rocking motion can ruin a new pivot bearing in short order. The engine will run fine for a few seconds without any belt, check that. We also nearly lost a front crank pulley, so check that too. Made some weird intermittent racket that did... -- Jim ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] Growly and vibrating tandem pump 300TE
The noise is definatley in the tandem pump area, that's why I am thinking the tensioner because it is right under the pump. Everything spins nice and free, which is the frustrating thing, there is a little play in the water pump shaft but not enough to cause it to leak. Urrrgh I hate these situations.
