Tightening torque on the belt tensioner clamping bolt is 75 Nm (55 ft-lb). Thank you, Pierre.

[@ItsAli4]

What to do? Well, First "Pray". Then pick up your phone and dial 1-800-FOR-PIERRE. Another great video from Pierre who is long overdue for some rest and vacation.

Great info, thanks!

[@BigmoRivera]

Those yawns are contagious I alway sneak off for a nap in the unimog when I get these yawns 20 min power naps really help with any work being done

How do you tighten the pulley, I've tried to tighten that screw but it snaps off the pulley

[@jimpeters3328]

Tensioner failed 20 miles up a dirt road picking up a hiker on Mt Rainier in my 2000 e320. Coasted down from 7,000 feet and got cell service. Searched and amazingly I found a tensioner at nearby Autozone and almost coasted the whole way watching my temp gauge as I fired up the motor for short durations. Fixed it in the parking lot… couldn’t believe I pulled that off. Great motor not so great benz so now drive a sweet 93 300d

Change it! Stop wrenching on it trying to save a few bucks. Also, buy the right belt like Pierre mentioned in one of his other videos. Take care of her and she will take care of you.

[@williambrashears3411]

Can I please get some some help I have a m102 and I replaced the tensioner with a febi one and I have snapped the large 19mm (twice now) on my 190e

[@SuperBranFlakez]

When I tighten the top of the 13mm tightener it spins u til it clicks and then loosens again any ideas?? It won’t tighten the belt

[@user-bn5ng1rs5c]

how to change tensioner lever on 97 e300d?

[@paddydaddyo]

I need to find an alternator mounting assembly for my ‘84 300TD ... some ham-fisted hack skipped replacing a broken tensioner bolt and over-torqued the other bolts to keep it in place. Pelican screwed me, letting me order major components that were not in stock. DYING in SC

[@b67fstb]

Is it possible that the tensioner got fatique.When you tighten the belt I run out of thread ?? And a smaller belt doesn't fit. I am talking about a 2445 belt cause a 2415 doesn't fit by all means. And by running out of thread I ruined the thread !!! A1032000870

[@christopher6161]

what about the om606

[@doe8939]

I have heard of Febi tensioners failing in a few thousand miles

[@mikefranco5651]

Made the mistake of buying a uro tensioner once, lasted a whole day.

[@Johnathan_Waters]

Uncanny timing! I am literally doing this exact replacement on an M103 as I watch this! Febi tensioner failed entirely!

[@shaazy]

Hope you made videos and pics! What were the signs yours was failing?

[@Johnathan_Waters]

@@shaazy Well this event was now over 3 years ago for me, but the belt was squealing at times when cold or when the steering wheel was turned to full lock, and the A/C compressor would shut down due to belt slippage being detected.

[@shaazy]

@@Johnathan_Waters Oh sorry overlooked that. Thanks a lot for remembering! I had a squeal and some AC clutch issues of late, the squeal went away after changing the belt but the AC clutch seems to be dragging. It spins slowly with pulley after AC is off when it's supposed to be completely still. AC is still working, and clutch engages when AC is on to spin at same pace as pulley, so I guess I'll wait till it completely dies. hehe
