What's up guys? I'm finishing up my 2.0 for the Mirage, and was looking for an OEM auto timing belt tensioner, and ran across this.

Here is the link http://www.streettunedmotorsports.com/p ... sioner.htm


My only question is, where the factory OEM tensioner is hydraulic, and makes up for vibration, how does this one work if its locked in one position with nothing to dampen or take the vibration?

Anybody ever used this, or have any good info on this? I'd love to get this because I hate the stupid auto tensioners, but am kind of puzzled as to where the movement goes when using this one?

Thanks in advance,
Scott

I would advise against it unless you like checking/adjusting it all the time. Then again I've never ran one, so my opinion is skewed

Thanks Nate.

I was wondering how does it stay locked securely, and would it need constant adjustment as well.

I'll stay away from this and I'll just order a new one from Mitsubishi

From what I've read it would need constant adjustment, but again I don't know of anyone personally running one. I would think it would need adjustment as the belt stretches, and I think that it would wear faster due to maximum tension at all time.

I've considered these as well and have always ended up going OEM. I've never heard of anyone having issues with the OEM hydrolic tensioners.. why change it?

Also they are probably just made because they are very simple and cheap to manufacture.

We had an OEM one on Shep's car.


And you know my theory, when in doubt- use the big boys for the answer.v

The two wheel guys run manual tensioners in anything that sees any abuse at all, and have zero reliability issues. In fact, reliability is the primary reason for using them, as the motorcycle tensioners tend to fail under sustained high rpm abuse. They also free up some oil system capacity (an irrelevant amount if the tensioner is working correctly, but still). If you plan to spend lots of time above, say 8k or so, it probably wouldn't hurt. And the timing belt should only stretch a little bit, and take a set unless you're really tightnening the crap out of it.

BTW, now that I think about it, the VTEC H-series Honda guys swap from hydraulic to manual tensioners for high rpm reliability, as well. And ENDYN just released a 'second' tensioner for B-series for similar issues.

thats because the stock hydro honda tensioners arent made for high rpms cause there really weak... they were never made to go fast from the factory.. just to get good gas milage... I know the owner of collective autoworks here in tucson...they build/work on 90% hondas..they have build alot of 12 and 11 sec all motor cars.. they use the solid tensioners and they dont like them..

now for the one on this topic.. stay with oem.. just imagin if you get the solid one.. and have to make adjustments lets say once a week for 3 weeks untill the belt is streached to where it will stay... taking that front cover and all that crap u have to do to get to it is a pain and in my opinion not worth it when u can set it once with the hydro one and be good for 40+k miles.

Yea as soon as Nate told me about the constant adjustment, I knew I'd go back with a hydraulic tensioner from mitsu.

The Honda manual tensioners that I have seen on the K series have a manual ratcheting mechanism that does adjust for the inherent stretching of the timing belt or chain.

This device is definitely not good for a daily driven vehicle that needs to have a timing assembly cover. For a trailered drag car that does not run for extended periods of time or necesarily need a timing assembly cover this item would be acceptable.

I have a buddy that had one. I don't think he has ever checked his. He daily drove his car before nuking a twin disc. I've had a stock unit fail. its not cool.

Most guys continue to use OE tensioners that have a lot of miles on them and are 20 years old which invites disaster. And trooper had even purchased a new one from Autozone that failed prematurely due to a dimple being pounded into the arm that sits on top of the tensioner.

I drove around for a long time on one of my engines with the pin still in the tensioner; effectively making the tensioner a "solid" style tensioner. It didnt skip time or snap the belt but having an auto tensioner to always keep the slack out of timing belt is far better for a daily driver than a solid tensioner that needs constant attention.

d series honda's used solid tensioners for years and years and they never had issues. i think the recommended replacement interval is around 160 000 km's or 100 000 miles in normal conditions.

The K's use a chain, and chains stretch at a constant, even rate with use. A belt should only stretch once, and only a little. Like I said, how many Hondas have you ever known to need the tensioner reset, ever?

D series Honda engines use a spring which constantly applies pressure to the belt.
But Honda still equips those engines with an automatic self-adjusting tensioner. I will admit I do not know how much or for how long a timing belt will stretch.

My OPINION is that no street or daily driven car should use a solid, non-self-adjusting tensioner.
