Torquing pulleys?

[sage2k]

Gonna install underdrive pulleys this weekend, do they need to be torqued to a certain # or do I just hand tighten?

i installed some on a new edge a couple months ago--hand tightened. they havn't flown off yet!

Usually, fairly "hand snug", then run the car a few minutes, check again, then drive the car, then check again.

The WP and crank pulleys have more than one bolt...should be fine. The Alt pulley should be put on using an air ratchet.

If you dont change ALL the pulleys, you may need a new belt.

many people on the forums have said i wouldnt need a new belt?

I changed all but the Alt. Pully with the BBK Pully kit, belt fits fine

The belt is made to fit based on the total of the diameters of all the pulleys....If that TOTAL number changes, the belt will not fit. (if you change to a WHOLE set of underdrives, the total diameter will not change)
