Hey guys,

my nevo idler pulley has got a loose center bearing and has been scraping on the bracket that the tensioner uses...

So I went ahead and ordered a 4AGE timing belt tensioner pulley, a GMB unit for $35...

All went well, added 3 reasonable washers to bring it out 1-2mm from the bracket when put on there backwards... until my tensioner ran out of adjustment and I was left with one rather limp 975mm belt... it has some cracks in it anyhoo.

Question; is anyone running the 4AGE tensioner pulley as their s/c idler/adjuster pulley? If so, what size belt are you using, I'd assume i'll need to drop back to a 960 or 965mm..

Cheers,

lawl dan just changed my tensioner on my gze, i got a 20v idler etc but im running stock boost etc so its different? i was using a 950 belt but i have a 955 belt atm...

[inertia]

Yes it's different, there is not enough room for a standard sized idler... however the tensioner pulley is smaller than the nevo one by some margin.

[(OO BANGN OO)]

doesnt the idler for the timing belt have an oval in the centre rather than a circle? i cant remember i just rember it being able to slide side to side

the timing belt idler/tensioner make for a great s/c belt idler/tensioner. you can use it with the braket or cut it off. a couple washers to space it right and i welded a larger nut onto the stock one so it sticks out making it easy to get to with a ring spanner... no more stripped nut as it's a bastard nut. haha.

i've sorted out the spacer behind it, luckily bunnings had m10 washers that the chinese make, so there was a few there that were double thickness .

I also used another one on the outside of the tensioner which mostly centers the bolt to stop all the slack.

I need to get another belt, i put some string all the way around in one of the grooves of the pulleys, it came to 945mm under tension and with the idler/tensioner pulley at full adjustment.

I assume this would be close to a 960mm belt required. Feral, what size belt did you use ? I have the nevo 175mm and the map supercharger pulley.

Ok,

5pk955 was too small...
5pk 965mm fits fine just fine and still another 1-1.5cm of adjustment left on the idler.

Car was shoving me forwards like a complete bitch whenever i'd try to nail it, i then saw my fuel gauge was bottomed out and the fuel had been sitting there for 1+ months...
gave her $25 of 98ron, which got me about 5ltrs lol, and she was back to screaming up the revs... I could swear it is quicker and i hear no belt hiss/squeal!!!!

for teh search ending

NEVO 175mm 4AGE Timing Belt Tensioner S/C Idler, belt is 5pk965 965mm MAP 4AGZE.

[kAm]

i'll keep that in mind dude are you running map or afm?

[inertia]

Running MAP. I guess an AFM charger would be 5pk975 or 980 and the belt wrap would be even more.

[kAm]

would that be cause the sc pulley is larger? (running larger belt)

[inertia]

Correct

[kAm]

hrmm so what do you need for the timing belt idler to fit onto the idler for the sc? just the idler and a few washers? so i would pretty much use the standard adjuster etc but just a diff idler pulley?

[inertia]

Yes a few washers, spaced it out 5 or 6mm from memory, then the tensioner put on backwards, then another washer to stop the tensioner from jiggling around too much on its 10mm slot.

Correct, I just used the standard adjuster.

I need to re-check mine to see if it is all still tight, given that with the thicker tensioner pulley and washers there is less thread to use for the nut.

[feral4mr2]

i used another nut with mine because of that, the stock one doesnt have thread all the way to the base of the nut.

[kAm]

just incase anyone needs the info. AFM gze with 175mm over size and nevo idler. im using a 5pk990 belt.
5pk970 didnt seem to work...

[inertia]

Thanks i'll replace mine next time I think of it . it's still tight as a nun's

[try_hard]

thanks kAm i think repco was getting sick of swapping belts every day after about then 4th belt. once i read this took about half an hour to drive to town an get the belt and fit it. now running 14psi. your a blood legend

[kAm]

i get 13psi .............

[inertia]

It's still running fine, about the replace the belts and will replace the Nut if I can find one .

[inertia]

FYI, the timing belt tensioner pulley is still going strong in it's duty as a s/c idler.. longest lasting of all that I've tried thus far... about to replace the belts again...
