timing belt problem

April 10, 2013, 04:58:33 PM

So I put on an esslinger cam pulley and now my timing belt wont stay centered on the pulley. When I turn my car on and get out to look at the timing pulley (I didnt have the cover on) and I can see the belt moving like a snake slithering towards the back of the pulley and slide a quarter of the belt of the pulley. I checked all three pulleys to see if they were loose and they feel very tight. I then put a leveler on the pulley and the valve cover and my engine is canted rearwards. I am not sure if it should be like that or maybe a motor mount died and thats why my belt is slithering backwards.?.? Any tips or advise?

If the belt ran true before the pulley change then the answer is Cristal clear. The new pulley is not running true. This can be checked with a dial indicator for run-out.

Well I dont have any dial indicators but I rolled the pulley across the ground multiple times and it always rolled straight.

Are you running the belt guide behind the cam gear?

Well the instructions said not to but then I called them up and finally on the fourth try calling and 15 minutes of waiting, they said to run the guide... I got it figured out!

The belt is designed to pull back slightly in to the block by the tension-er. This in turn will make the belt ride slightly on the FRONT side of the guide.The GUIDE PLATE MUST BE USED. If you do not run one what you described will happen. I assumed you were running one when you changed over. It is mandatory to use it. Like i said if the stock one worked correctly and the new one did not your answer was Cristal clear. And you found out that you need that plate. A quick look at the plate will show you that the belt is slightly pushed against it by the tension-er to keep it from walking. Years back FORD had an issue with the tension-er and came out with a new setup. I have an AUTO TENSION-ER that i came up with that works much better than the stock one. Is your belt square tooth or round??? An UP GRADE to a round tooth would have been a good thing at this time. They work much better. Glad you figured it out!!
