Cant get timing belt to stay tight...

[Hesh724]

I have the shop manual i have the motor mount and cover and pulleys off and stuff and i have a hydraulic that is less than 1 year old off dsm graveyard .. or Xpsi cant remember but in any case its very new. i have the old tensioner pulley still though. I got the "special tool" for the pulley and i have been installing the Hydro tensioner and pulling the pin and slowley tightening the pulley in increments untill i hit 4mm. then after a few days of driving the belt has come decently loose again? i wonder if i should be using locktight on the Tensioner pulley center bolt? or what else could i be doing wrong. i have followed the shop instructions to a T didnt work and so i tried my own way and it holds longer than it did but after a few days it always seems to come loose again? Any advice would be GREAT!!!

Is the tensioner leaking? Are you torquing the tensioner pulley to the correct specs?

You have to check the Tensioner and the Pulley, Have you seen where the Tensioner is at before redoing it?, Have you seen the Pulley as well?, You have to check both of them to figure it out, If the pulley is not where you set it up the first time, then you have the problem at the pulley side, But if the Tensioner is not where it was set, then the tensioner is bad, Put some thread locker on the bolt from the pulley, to make sure that it stays there, Does the pulley bolt has a washer on it, Check both closely or just put a new tensioner and pulley and be done with it.

Also you are putting the slack towards the back of the motor (tensioner) correct?

I think i know what i was doing wrong. i guess i was being sloppy and over torquing the idler pulley against the belt and over time (2 days) the tension and vibration of the belt against it pushed it back a bit. so this time i set it with an actual torque wrench and letting the auto tensioner do the work instead of the pulley. Knock on wood.... S#it is stressing me out.... also i did a couple things out of order trying to be slick . but im not apperently

Knock on wood.. Damn dsm has one issue after another about to buy a labaron! JK

well i have it all back together AGIAN!!! haha but i was wonderign if i need to reset base timing like do i need to readjust the CAS?
