Same pulley for SVX,WRX, LEGACY and Outbback?

Ovidiu STAN · #1 04-12-2002, 12:26 PM

I had to do some research to get a new pulley for my SVX. For those who don't know (yet ) this is another SVX problem.

The (crankshaft) pulley (or harmonic balancer) is made from a core and a crown and in between there is a rubber layer. This rubber ages and finally your pulley fails.

Diagnostic?

The pulley starts slipping, no AC, no alternator, no servo and most important it will sturt rubbing against the timing cover (the crown will start advancing toward the timing cover).
As a prelude

you will notice that is running a little bit (1/20") excentric.

After this introduction comes the question:

What years and models of Subaru you know that is using the same pulley?

Anybody could share his experience?
I found that 98 Legacy has the same pulley. Can anybody confirm that?

Thanks

To my knowledge, this is correct. That means an aftermarket pully for any subaru, even the new WRX, will work on the SVX. I think. Lets see what the others have to say.

There was a suggestion from Beav that this failure is caused by over tightening the belts. I have noticed that after market belts require more tension.

Just to be clear, overtightened belts can cause the problem but that is not the only possible culprit. Deterioration of the rubber isolator, caused either by heat and old age or by saturation from oil can cause the problem. Also a high-drag device such as a failing alternator, p/s pump or a/c compressor can overload the abilities of the pulley.

It used to be that small block chevys were the cars to chuck the pulleys most frequently but now it seems the SVXs and the Mazda MX-6 / Ford Probes with the 2.5 V-6 have taken over.

Thanks to you again Beav for coming up again with the penultimate posting !

I had been wondering about this alleged bogey but once again my fears have been laid to rest as this is not uncommon in all sorts of arias involving bonded rubber components and is not too much of a black mark.
