Jeff: My TR will be ready for it's major next year. With all the good information you are sharing with us, I am "almost" tempted to do my major now.......one step behind you. HAHA I hope you are taking a lot of pictures, and notes, since I will be talking to you a lot when the time comes. | ||

THANK YOU GREG....PETER....AND VERELL !! I think I can now do this with some level of comfort. When I do I'll take some pics and post them with the procedure I followed. And then I'll wait for feedback before doing anything more to the engine. If I still make an error, I'm sure someone will let me know. Thank You again guys for all your help! | ||

Jeff, There's a step before your *3. 3-. Once the tensioners have reached their furthest travel, Turn the engine over by hand at least 2 &preferably 4 times to ensure that the tension has equalized around the belt. Best done w/ spark plugs out so you aren't fighting engine compression. The tensioner will move in & out slightly as this is being done. Notice where in the engine's rotation the tensioner is at maximum extension. After the rotations, bring the engine around until the tensioner is at max extension & lock it down. Make absolutely sure you don't turn the engine in reverse. The belt will jump teeth on the cam drive gears(don't ask, but I was lucky). | ||

Jeff, I destroyed mine when I tried to pull them off. It didn't matter as they were garbage anyways. The new ones I got I simply pressed them on, using a bench vise and a piece of pipe (which had an I.D. that was slightly bigger than the bearing shaft, but would fit comfortably on the bearing inner race [The part which slides onto the shaft]). | ||

Thank You Greg for the info. and pics. I don't have a TR tensioner in front of me, but your pics do look very similar. How did you remove and replace the bearing....are they pressed on or do they simply slide off? If I recall from scanning the archives, a TR's bearing was destroyed removing it....this implies that it was pressed on. The problem I have with my shop manual is that it has a written procedure that references some numbered diagrams. But when I look at those diagrams, there are no arrows or numbers pointing to any of the bolts, screws, or other parts mentioned in the text. Pretty crappy! Thank You Again for your help! | ||

Pic of bearing assembly on the car. You can see the locking nut tightened down now. Hopefully this is close to the TR assembly.  | ||

Here is a picture of the assembly. Regrease those puppies too, the spring.  | ||

On the 308 there is a locking nut. You loosen it and compress the tensioner assembly then lock it back down. I removed mine off of the car to replace the tensioner bearings. I thought the TR was close as the tensioner bearing assembly goes. I will look for a pic of one. I used to have one on my other hard drive. | ||

Second posting on this subject. I've reviewed the archives, and am still foggy on this procedure. Sorry to be a pain guys, but I'm afraid of making a costly mistake here. 1. Can you compress (release) the tensioner by hand, and if so, how is it locked into place so you can change belts? 2. Do the tensioners need to be removed from the engine to replace bearings? Are they pressed on? 3. I assume the tensioners are locked into place once they have reached their farthest travel in tightening the belt? 4. What is the torque for the tensioner bearing retaining bolts? Again, I don't mean to be a pain. But the weather has been great lately and I'd kinda like to get my car back on the road. Thank You for any help...it's appreciated. Sincerely; Jeff |
