Default Pulley Torque Specs

I am probly gonna be putting my lightweight pulleys on this week, but need some help.
I know the crank pulley needs to be torqued down to anywhere between 75-105 ft/lbs but what about the Power Steering and the Alternator pulleys?
Also, how do I get those off (P/S and alt.) without having the pulley spin around as I try and get it off?

The crank pully is more like 160 lbs/ft. As for the other two, check with your local Suby dealer. They may be able to tell you the torque specs.

Hmmm, well I know that in the posts im searched iv found many different choices, so I really dont know the real spec.

ANYONE with a 2.5 engine factory manual (Phase II engine) tell me what the pulley torque specs are?

I have a '99 RS and have had the underdrive pulleys on since 2000. There great and do make a difference. You'll see a huge difference with the OEM and MOD pulley weight.

When I did the change I had no torque wrench. I followed these instruction and found everything went smoothly.

I-Club Pulley Instructions

You will need to pull like hell and may need some one in the car to hold the brake (or steering?) as I did. I also had to go to sears and buy a long breaker bar type for leverage.

When it came to torqueing it down I just pulled liked hell(being careful of course) to the point where I thought it took for the OEM.

The only issues I've had are with the alternator belt. I have to adjust it every now and then as the seasons seem to affect its tension.

If you can't find the exact specs, but are mechanically inclined following the above instructs should be fine.

Absolutely wrong. 160ft lbs you will stretch the crank pulley bolt. Possible causing shortened bearing life and vibration.

The factory torque for the crank pulley is 90 ft lbs. Most good tuners recomend 95(no idea why but they do)

If ya don't believe me ask Shiv, Trey Cobb, or any other reputable scooby specalist!!!

OK...

Here's a link to a page from the service manual stating the stock pulley torque specs.
