I remember reading about there being two different styles of the tensioner and guide. There was and old style and a newer style.

In terms of installing there is no difference correct?
Also which one do I have, not sure if its the old style or the new style, thanks.

I thought the newer style tensioner wont fit in the small access window.

Dave

 

not too sure. but the new style would fit if the whole timing case was off wouldnt it?

 

Yeah, that's the main thing the poster was saying about the new style- it required the case to be removed.

Dave

 

The difference between the old and new one is the angle at which the Guide sat, which then required you to change the tensioner also.

 

 

yep but you can get away with jus changin the tensioner.but its not recommended

 

daaaamn so I have the wrong one??

 

And wanna email me a copy

Ospit1@aol.com if you wanna be my hero

 

pm sent.................

 

That might be the re-revamped version, I believe I had the same guide and returned it because it wasnt the right one(95)

 

yikes. . .

its like #3 on fast . . the alternative but 26 instead of 25. I guess I'll find out when I put it on. . .

I'll keep the right part number on hand incase this should not fit.

 

Well the way David B the parts guy explained it to me is, the new tensioner is to large to fit through the door like the old one did...you need to remove the entire cover to get the tensioner in.

part #'s

# 1307031U00
# 1307031U01
Bad New part number is 31U26

Old part number will be 31U00 or 31U01 and Will fit

The tentioner that wont fit and requires the entire cover to be removed is the 31U03 or the 31U26 which is the kit.

well as long as it still fits that is fine. I plan on putting this on when the motor is out of the car so that factor isnt a big deal just as long as it will fit.


So from what I've gathered its just the old style that could be installed without removing the timing case, the new part requires the timing case removal. But both parts once installed both work just fine.


Thanks for the info this clears up some things for me.

 

13091-2Y001 is the one i installed in mine 2 months ago. Definetely cured the problem.

 

OLD TENSIONER//OLD GUIDE



NEW LONGER STYLE TENSIONER//OLD GUIDE

PICS thanks to JIME....This is the NEW style Tensioner, with the Old Style Guide in a 4th gen

The

 

yea I saw those pics. I will be all new, no reusing old parts for me

 

So does he in fact have the older part number, that will fit?

aww man, I have the bottom version, son of a..

 

I have the new style.

 

When was your car produced?

 

... 8/94 .... wondering if a possibly unupdated 96 tensioner would work?

 

Mine is 4/96.......


So that is saying that on 1/96 it changed, but that one is also not the current one right?

 

No guys, these part numbers just recently changed. Nothing to do with the stock part number. They are all, from 95-99, the SAME EXACT part number.

The larger Tensioner was just changed last year from fix from Nissan. This has Absolutely Nothing to do with Production dates at all

-matt

 

Guess I better start looking for an old one.........


From the looks of it, finding one will not be easy.

 

Dont mind that PM... and i dont think you'll find one

 

That is what I am thinking ....

 

I forgot to mention last night that the dealer I spoke with gave me the 13091-31u26 as the old part. He told me they had another one with the #13070-31u0a. I do not know if this is correct. He also told me that I could just change out the tensioner with this one. I also do not know if this is correct, reason I came back on here to check. Maybe someone here could look into it. I will do some digging at lunch time.


**Edit**

Has anyone tried going the aftemarket route for this? What about getting one from a used engine at the junkyard?

 

Never really tried the aftermarket route. Could be something you do when you pull the stock one, go to the store with the stock one and see if they are the same size. I would think that would be a good idea.

No Way. They will all have alot of miles on em beacuse a junk yard with a low mileage motor wont start pulling parts from it

-matt

 

Here's a thought..inside the tensioner, there's an o-ring that basically seals the piston & bore. This way when oil is forced into the tensioner chamber, it pushes the piston out against the chain guide. I grabbed an o-ring from my mechanic that was an exact replacement. I'll be putting it in when I get some time & report my findings.
I was one of the first guys that replaced my old tensioner with the new one (twice), and only realised that they were different after the fact. It worked in the sense that it got rid of the start-up noise, but as you can see in the pics, it ain't pretty.

 

I just finished speaking with one of the parts guys at a dealer here in town. The guy was actually trying to help me and was on the phone with me for a while. He told me the new number, 13070-31U0A, also requires the changing of the guide. I guess I can try getting the Autozone tensioner and see if it works. The shop I go to quoted me $400 dollars labor to change out both the tensioner and the guide. I think this is not that bad for all the labor involved. They had quoted me $175 dollars to change out the tensioner out the door. They were going to use the OEM one though. I will take the Autozone tensioner and they will check to see how it measures up to the old one. Hopefully the aftermarket one goes in....


Edit:

This is the link and picture to the one from Kragens. It looks like the revised version.

Just for the record, the new redesigned tensioner WILL fit in the access hole without removing the entire timing cover.

But what's the point? You have to remove the entire cover to install the matching guide, so it does you no good at all.

 

Please look at the pictures I have posted in the beginning of this thread. We know that the new tensioner fits through the hole but does NOT line up with the guide you have on in the engine now. Nissan is selling a "package" that includes the tensioner and the guide in one for that reason. The guide requires you to remove the cover to install.

Can I install the spring and/or piston and/or O-ring from the new tensioner into the old tensioner body?

There's no way I'm taking my timing cover off. Ever.

 

[QUOTE=matty]Well the way David B the parts guy explained it to me is, the new tensioner is to large to fit through the door like the old one did...you need to remove the entire cover to get the tensioner in.

I am simply trying to clear up the misinformation from Dave B that you posted earlier.

Because it is simply not true.

seriously...

 

Hmmm, would be good to know. Having some issues with yours too Ben?

 

My tensioner has been flaky for a long time. I'm going to be changing the water pump this weekend, so I ordered the new tensioner kit too.

If I can't swap the new bits into the old part, then I'm just going to put in the new tensioner with the old guide and live with it.

 

I started noticing the noise only while driving. This happened within the last month or so.

Keep us posted on exchanging out the new bits into the old part. I would much rather go this route.

 

I "rebuilt" my old tensioner using the plunger, spring and seal from the new one. It all fit right together.

Of course, I dropped the plunger in the timing chaing cover while removing the old unit. Luckily, I was able to fish it out with a magnet on the first try.
