Underdrive Pulley Installation

water pump pulley to hub bolts 15-22 ft. lbs. and crank pulley to damper bolts 35-50 ft.lbs.

If you don't have a torque wrench, W/P should be firmly snug. You can get them tight enough holding the pulley by hand as you tighten with the wrench. Just don't lean real hard down on the pulley when tightening so you don't break the pump. It's not fragile, but some people get carried away, I've seen some funny breaks

On the crank, get them tight, but don't kill them.

Waterpump- unbolt the fan and then the bolts on the waterpump pulley and then bolt the new pulley up and the fan.

crank- unbolt the four bolts on the pulley and tap the pulley off with a hammer. Just bolt the new one on.

I just used a regular ratchet and socket (and allen socket for the new one)for the crank pulley and a ratcheting wrench for the fan and waterpump.

I actually wouldnt use the alternator pulley. I used it when I put underdrives on and it basically didnt charge the battery at idle and the headlights dimmed. Even after putting on a 130 amp alternator the charging at idle sucked. I put the stock pulley back on and now it charges fine. There was a difference of atleast one volt between the two pullies.
