Title: PS Belt Size
Post by: rb6667 on May 20, 2012, 23:51:07
After searching the archives, I found that the only way to take off the PS Pump Belt, short of taking off the ps pulley, was to cut it off.  Mission accomplished!  Now on to a replacement.  The size belt I cut off was indeed the correct size.  13mm X 750mm.  This appears to be very close to 13mm X 29.5"  Hopeful someone can confirm that this size will fit, or advise what size is needed. 

Thanks in advance.

Doesn't the PS belt have a tensioning bolt(6 mm or so)???   (Amateur Pagoda ol ogy. ..)   below the dizzy?

It does, and you can turn the tightener back so the belt will go slack but not enough to take it off easily. A sharp knife works good for that.
I start it on the pulleys and then bump the engine which will make it pop on. You can also turn the engine over by hand and slowly feed it on to the pulleys.

I have been down this road not too long ago on this forum. That sounds like the right size of belt and you do have to work it on like the Dr. says. I used a rubber strap wrench around the crank pulley and was pretty easy. Don't bother looking for a slightly longer metric belt because they don't make one that will work. The next size up is just a bit too long to tighten up.

Just not enought adjustment range on the P/S bracket. Kind of stinks.

UPDATE!!!!  The 29.5" will not work.  Just a bit big.    I used a 29" belt, and it works.  I've had my hands full getting belts to work on this car.   Had a similar problem on the AC/Water Pump/Crank belts as well.  That was a real nightmare.

I'm curious why Mercedes used 2 belts here.   It obviously does serve as a back-up system, but is there another reason?
