Anyone ever try installing the front pulley (all 72 ft/lbs. + of it) using an air-driven impact wrench? I used one to take the thing off, very simple. But I'm not sure what the resultant torque would be with an impact wrench when putting the pulley back on. It would sure be a lot easier than sweating on a manual torque wrench while trying to keep the pulley from spinning.

Yepp,, Thats the way Id do it, Thats how I do the clutch, dont hafta hold the trigger down, just Pop it & itll ram the nut up before the clutch basket can spin,.

On that pulley, yea, nail it, just make sure you have the nut started good. I like to let whatever Im tightening to be away from the landing & hit it, it spins down hard before the impact even starts banging.

They usually cram lugs on way too tight, these pulleys get loose. Theres a technique to what I am saying,& I am a good mechanic. Im not talkin Dogin it, Im talkin makin it run up & snap & be pretty tite before the impact even starts hammerin,

proper impact usage


Sometimes, tho, not all the time,an air hose is involved.
& Yea, quick blasts on the trigger will work wonders,.
Ive been stuck with a 22 gallon, wimpy compressor from Harbor Freight for 6 years. When I worked in shops, there was all the air a guy could use, 2 big compressors with big motors feeding the painters & bodymen, but Ive had to learn how to get the most work out of a little air,

I've never heard of any such thing and quite frankly, that sounds ridiculous. The main reason brakes "warp" is that, for starters, people buy low-quality rotors. Then they do very hard and long stops(like getting off the highway and stopping at a red light) and proceed to mash their foot on the brake like they're trying to prevent a 40ft trailer from rolling down a hill. The brake rotor is now way too hot and without air movement to cool it down, bits of the pads weld to the rotor causing high spots. If you're like me and don't care to spend the money on quality rotors, you can't let your vehicle sit in one position after a hard stop.

And believe it or not, you can't feel a warp in a rotor, you can only feel a high or low spot. As long as the sides of the rotor are parallel, it can look like a record in the sun and you won't feel it.

I've been an ase certified brake tech for 26 years. The number 1 cause of warped rotors is uneven torque of the wheels. If they are not all the same torque, as the rotor heats up it will warp to the side of the looser lug nuts. This is a practice taught in all auto tech classes and I have witnessed for myself over the past 26 years. the shop I have worked at for the last eight years has little to zero lifetime replacement brake pads that also have warped rotors. Think whatever ya want, makes no difference to me, but the cars I work on don't get warped rotors half way through the brakes pads life. Lol just google "does uneven wheel torque cause warped rotors"
