Another timing tensioner question

[UrN2nd]

Ok I've search the forum and have a quick question. I put a new tensioner on my 2g 7bolt. I se t the tensioner pulley to where both holes are on the bottom, then pulled the pin on my tensioner. First the pin came out easy. Then the tensioner never extracted itself. I actually had to put a screw driver in and pry it out. But once it came out it held and didn't retract. But I read that I should rotate the pulley till the arm touches the tensioner before I pull the pin. I pulled the pin with a tiny amount of a gap. And after it tensioned its extracted out about a1/4 of an inch, the belt is good and tight. But I just wanna make sure. I'm just worried about the tensioner didn't move out on its own at first. When I pryed it a tiny bit to give the belt a lil tension it moved out on its own.

The tensioner is designed to remove slack over time as the belt stretches. When you pull the pin out, it's not going to snap back really fast. How long did you wait before you used the screwdriver. I believe you are supposed to let is sit for 15 minutes or so to let the tension build up. Same reason why you should loosen the tensioner slowly, it's not meant to move that fast over a short period of time. I'm not an expert but this may help clear things up a little.

At this point, unless you're really concerned about the condition of the tensioner (not sure I completely understand), just worry about whether or not it's in spec.

You could depress the tensioner and reset it to ensure proper operation. GSX_beast gave a fine description of expected behavior.
What concerns me is the way you described the action of the tensioner extending. Since the spec is pretty much the same as when the pin is still installed, I would hope that the rod didn't extend much if any, and certainly not require coaxing with a screwdriver.

I'll post a pic. It extended a lil but the belt had a lil slack so I pushed it up to get the belt tighter. What's the belt deflection spose to be?

I think this will help make things more clear.
But still post a picture. Everyone likes pictures.

There should already be tension on the belt before you pull the pin, the tensioner extends to keep tension on the belt when it stretches. The rod is only supposed to extend out .15 - .18 inches , if its extended 1/4 inche then its extended to far.

Looking at the picture, that has no tension at all. Rod is fully extended. Running the engine like that is just asking for the belt to slip wiping out the head. Spend a couple of bucks for a feeler gauge and set the gap between the arm and the tensioner body between .015 and .017.

It's tight. Super tight. But ## saying the arm is extended too far. Ok ill reset it.

Thats way too far extended. I would follow instructions on how to compress that tensioner,put the pin back in, and do it right!
I used a vice to compress mines but you have to know the procedure for using the vice on the tensioner or you will blow out the seals that are inside of it. It is an easy process.

Some guys do a timing belt without using a timing belt tensioner kit but I believe that using one would make the job a whole hell of alot easier especially on a stock 2g block and head setup. Just my two cents!

Guys have posted good info on how to do a timing belt properly helped me alot.

I used the tensioner pin sliding method which helped me determine how tight to make the belt and when the tensioner was set within spec.

Just follow the directions and don't be afraid to redo it until the "grenade pin" can be reinstalled after your done. The key thing is to not put so much tension on the belt that the hydraulic tensioner is bottomed out but not so little that the pin can't be put back in. Just keep redoing it until the pin can be slid in and out with minimal resistance.
You can make the screw tensioner tool yourself with some thread stock and a couple nuts but considering how cheap you can get the whole set for that I would just go ahead and get them to make it easier for you.

The instant you pulled the pin that rod should have extended, not sat there and required you to 'assist' it extending. You should also be able to set the grenade pin back into the locking hole on the tensioner.

Better safe than sorry - Pull that thing off, send it back, and get a new one. If you had to 'help' it extend then I wouldn't recommend trusting it. That's the livelihood of your engine we're talking about here.

Got a replacement one on the way. And I'm makin a tension tool out of all thread so ill give it another shot

Is this the correct timing mark line for a 96 7 bolt

New tensioner is in. On a another note I compressed the one that I had to assist and it extended perfectly after that. But I still don't trust it. So I'm replacing it anyways. But is the crank mark correct?

 

[synthetek]

Yes, it looks correct
