I have found that SRT-4 have timingbelt idler which can be used in TIII. It is a bit smaller in diameter and you do not need to use washers. It has bolt integrated so that's why I drilled and tapped a hole in A/C bracket. I also added nut to other side. So far it has been working fine over 10000km (over 6000miles).
Example gates P/N T42121
So this seems to help?, i have yet to have belt failure or cam problems and ive been setting mine by ear??? probley have 40+k miles of doing it this way.
On stuff like this, I'm getting to be a fan of pressing the bearing out of the original part and replacing it with one made in the first world. US/Canada/UK/Germany etc... bearings themselves cost $2 bulk retail maybe $5 ... the aftermarket replacement stuff is real hard to find without nasty Chinese bearings in... the one I had fail on a non-delicate 8v non interference motor came damn close to wrecking the valvetrain, and spat metal all over the engine bay where it could have caused damage in other parts.

Can you press out the bearings on the stock idler though? I should take another look but I thought part of the reason Lengel made those rebuildable ones was to fix that issue.Originally Posted by RoadWarrior222
doh, point.

Lengel makes rebuildable tensioners AND idlers for the TIII and they are very high quality pieces as I have bought several sets so far. He can also sell you rebuild kits for them which consist of new bearings that press in. I myself have used a timing belt tensioner pulley sourced from a later 3.5L V6 Concorde/LHS and used it as the timing belt idler pulley on the TIII. All it needed was a washer to space it out a bit and it worked great. Very cheap and probably always in stock at NAPA Autozone Oreillys etc..
Can someone with search skills link me to Lengels? I looked in vendor forum and TIII and cant find em.
FWD-performance has them listed on their site.
Yeah, I try to buy stuff from her and she doesn't get back to me. Not sure how they stay in business...
What do u mean "try"? Just go on the website and order. I've never had a problem...
just PM lengel its like $250 or $260 for the pair (idler and tensioner)
I asked for something 1/4" off from what they have on the site, so I can't just go on there. I will PM him as soon as my next check comes in, thanks.

Good to know, I'm putting that into my t3 info file!
I used the srt4 idler at a cost of 28.00 (my cost) at oreillys you cant go wrong, I was planning on using the 3.5 one however they were out of stock. Srt4 idler worked out great. No washer needed as stated above. I just put a fender washer and nylock nut on the back side. I tapped my hole for the attached bolt.
I still have the Koyo one with the countersunk bolt but this is another good find,
