Engine/Transmission (1994 - 1998) belt tentioner? Someone have a pic?

[hereismylife]

I am tring to get a belt for my engine. I am wondering where the tentioner should be at with the belt on. I did read in the haynes manual about it being pulled to far is not good and there might be a mark where it is to loose and to tight. Anyone have a pic of this.



Thanks Joe

Joe...

Here is a shot of the belt routing taken from Dave Fritz's site Dodgeram.org . It shows the A/C and Non-A/C routing of the belt for you. The circle with the arrow in it is the Belt tensioner... ..... Andy

thanks. I did know that but I was looking for where the wheel should be. Anyhow I did get a belt that finally fit I think. My tentioner is facing straight down. I did see others like this so I hope I did it right. .



Thanks Joe

I checked out an old tensioner I have and could not find anything that resembled index marks.

Every tensioner on every car truck I have worked on has had the indexes , if your have the tensioner mounted correctly with a belt on , then use a tool to move it from lose to tight , you should see something almost like a thick casting mark moving between 2 none moving casting marks , sorry no picture & not quite a 1,000 words .

Then it would seem you have never done a 12 valve Cummins. The tensioner is mounted with one bolt and has a pin in the back that fits into a corrosponding hole to keep it from rotating. There is only one mounting position and no adjustment provision.



Joe, mine is a little left of straight down, viewing it from the front. However the belt has about 90k on it and may be stretched a little.

GAmes , the tensioner is spring loaded & swivels , on the out side of the spring housing is wear the marks are , the part you are referring to is the back mount with the pin keeping the mount from turning against the spring tension , that why its called a tensioner , to remove you put a 3/8 " drive into it & turn to remove tension so that you can change belt , we have a failure to communicate .

I guess so. I am well aquainted with the tensioner on my truck. I have R&Rd the belt many times and the tensioner once. Your previous post suggests there is and adjustment for tension obtained by using a "tool to move it from lose to tight" after the tensioner and belt are installed. I was pointing out that once installed there is no way to adjust it. And there are no "marks" on the old or new one, why would there be? There are raised surfaces that serve as travel limit stops.

I was not suggesting adjustment , just that the marks show when the belt has stretched beyond what the tensioner can work with .
