Timing belt issue

[thesupragod]

I have a problem. Wen installing my new isuzu timing belt i find that the tensioner is not tensioning anything. The belt is very loose, and im not sure what i can do about it. I have removed the hydraulic apparatus located below the pulley. It doesnt move, im not sure if its supposed to.

Any info would be great!

Thanks in advance.

when you removed the hydraulic apparatus, did you put a small pin in it to keep it down? I recall doing something along those lines. Because otherwise it would already be pushing all the way out.

Like I said, Im not positive thats what has to be done, but Im about 90%. I kinda wish that I had one infront of me to look at.

Yes the timing belt hydraulic tensionor has to be pressed in.

It will not be easy, you have to have a c-clamp at the least. Once in you have to put a pin like object ( I used a allen that was small ) to put in there, put on with the two 12mm bolts have the belt correctly one,

Cam gear lines facing up, timing on the crank set at 0 degrees, and then pull the pin. it will self adjust.

Now you said it was loose, which means it may be broken. If it is correct it would be tight, and you would have the hardest time getting it on.

So check it out and see if it is all the way in, because from what you're saying that is what it seems.

well... thats interesting. Do you think that i could just put it in place with the bolts threaded losley, then tighten the bolts up evenly?

No you need the pin there. Then you can tighten the bolts to their torque, and then pull the pin out.

It's not the correct way to do it, but that's the way Ive did it and I've taken mine apart three or four times and installed it back in this way everytime.

The way Ethan told you to do it is the correct way. I did it that way the first time and it was a bitch. So far I haven't had any negative results from doing it this way. Good luck.

The best way is to put it in a vice and compress it till you can fit a small allen key wrench in it. You should also always replace the tensioner when replacing the timing belt, they are less than $50 and you can get one for a 2jz anywhere.

I thought the 2J and the 1J tensioners were different, or was that the tensioner brackets?

Also, why was this threda moved? I know it said for Isuzu, but im fairly certian hes talking about the Isuzu belt that fits a 1J. Thats why i had in mind

You can get the correct timing belt from Jeff Watson for approx. the same price as you can the isuzu belt. I think mine cost about twenty dollars.
