A couple of weeks ago, the AC compressor clutch on my wife's '04 C240 shattered and took the belt along with it. I was planning to get around to R&R'ing the compressor this weekend but a package arrived yesterday with the wrong compressor (7SEU16 vs. 7SEU17C.) The problem is both my wife and I needed our cars this weekend so I had to come up with something....or rent a car for one of us.
What I decided to do, since the shattered clutch left enough clearance for it, was to install a shorter serpentine belt eliminating the AC compressor temporarily. But searches on this and other MB forums gave me no hint as to the belt needed to do so.
Thanks to the patience of AutoZone staff and a couple hours of trial and error/back and forth, I found that the perfect belt to do this was their "Duralast 910K6" or "6PK2310" (same belt-different number.) Just pull back the tensioner, run the belt from the PS pump directly to the crank pulley instead of where the AC pulley would normally go and the job's done.
A 100mph road test for 10 miles proved that it worked like a charm!
Annoyingly i once ordered a 2315mm belt by mistake since both the 2420 and 2315mm belt is listed as fitting the m271 engine. Now i understand what the shorter belt is for, thanks!
Thank you so much for your post. My 1999 E320 has a similar problem and I too do not have the time to get it fixed this weekend. I had the same idea and was about to go get a tape measure in order to guesstimate the circumference. Luckily, I had a moment of lucidity and decided to do a search on the web. Luckily, I found your post and confirmed that the layout of your wife's car is the same as my 3.2 V6. I installed the belt you referenced and the bypass is working perfectly. Now I can drive the car and have the time to fix the compressor issue without rushing. You saved me hours, if not days, of guessing. I can't thank you enough.
On my wife's 2002 C230 (4 cyl Kompresor engine) I was able to use a 6PK1755 to by-pass the AC compressor while I waited for the new one to arrive. This is the driver's side belt that drives the water pump, power steering pump and the AC compressor. Like most MB designs, it takes much longer to gain access to the serpentine belts than to change them. The gents at Advanced Auto don't know how to find them by length but they let me rummage thru their stock to locate one. Any length from 6PK1755 (1755mm long) thru 6pk1765 should probably work too.
*** PLEASE HELP****So I have a w220 s500 and I replaced my belt with the one stated to by pass a shot ac compressor for the mean time and save me towing $. Did anyone else have clearance issues by or around the tensioner bracket?!?

not sure if you're in the right forum. Anyway if the belt is barely touching the bracket may be you can use a metal file and grind away a thin layer to get enough clearance.

sorry about that... I figured even if it is a C class thread it was one of few threads out there that actually discussed my current situation. it was a similar enough topic as I've found that this belt part # is also compatible to do the bypass method on m113 engine as well.
So I bypassed my ac compressor and the belt fits but seems to be pretty close. I started my car and it doesn't seem to be rubbing or making marks on the belt itself so it might be ok... maybe I will try fiiling it down a little, thanks!
I was in Pecos Texas (heading to Denver) when my ac clutch pulley went bad. The Serpentine belt shredded and popped off. There was an autozone open that day but they only had sizing for the regular serpentine belt (945K6...which is 94.5" with 6 grooves). I had to bypass the AC to get home so it took a little time to find out what length I needed to do that. I saw someone else which a different model vehicle had done a similar bypass and appeared to have the same size specs for the with-AC belt and ended up finding that the 91" belt worked to bypass their AC. This is just to verify that to bypass the AC on a 2007 GL450 you can use the 91" 6 groove belt (910K6).
I put it on with my daughter's help in a motel 6 parking lot (didn't remove the radiator fan so it was tight to get at). We were back on the road and the had no problems the rest of the way.
BTW, the GL450 takes a 17mm socket on the tensioner pulley to move it so you can get the belt on...

getting ready to try this tomorrow on my 2008 GL450. Was driving home from Hot Springs, AR and battery light came on and steering got right. Knew i had lost a belt. Luckily was right at an exit and could get off and get right to a truck stop and shut it down. Found the idler pulley shredded and belt cut in half. This was 2 hours from home and we luckily had an older daughter at our house and she was able to bring our other SUV to pick up the group. Went back this morning with tools and pulley and belt and 45 minutes later, thought I was ready to go. Start it up and belt was smoking. Shut it off and found the Ac clutch not spinning. Really did not expect to find this sort of thread for this type of vehicle, but so glad I did. Fothir, thanks for posting the info for the GL
This post was from 8 years ago, but saved me today.
The part number was correct and took 5 minutes to install.
Thanks so much!
I needed my car fixed to get to work, but don’t want to spend $700 on new AC compressor for a car that does not have much life left.
I used the Duralast 910K6 and my car is a 2005 Mercedes C240 wagon.

This happened the other day and it was an absolutely terrifying experience however, I am very lucky because when the belt was shredded, it did not destroy any hoses, components, or fan blades.
My car was around 165k, approaching 170k miles when its AC Compressor Clutch seized and got me stranded on the highway in the middle of nowhere in PA.
I made a YouTube Video explaining the symptoms and what you can do if you're stranded but close to or near an auto parts store.
