Cambelt idler question...??
 

Right, new idlers are on the way, but, there are 4 idlers, (my00) one small, one toothed, and two plain.... the two plain ones on mine are different to each other, although they would appear to be interchangable.... one is a single bearing one, and the other is a twin bearing type..... i reckon the twin type would be better for both.... whats the deal with them being different...???

Ron...

If you search at "Subaru Fast" part programm you'll see they give you the twin type for both if you are going to change them, although the single bearing part has in the edge a small guide to keep in place the cambelt.
These are the parts I bought for my WRX MY03, keep in mind the only different part in our cars is the 13073AA230:
13028AA240 cambelt
13033AA040 tensioner
13085AA080 idler
13073AA190 idler twin bearing
13073AA142 idler single bearing
13073AA230 small idler
12369AA011 crank bolt, just for the case

Thanks Jim.... i've ordered two the same.... so fingers crossed they're the twin type....

There isn't problem RON in every case, this is what Subaru suggests for every cambelt change, I am the one who prefer to keep the same setup with what comes factory fitted!
