    Do I really need an impact to install the pulley on an alternator? The instructions say to tighten with an impact until the lock washer is collapsed fully (Do not over tighten!)...Why couldn't I use a ratchet?

    Do what all the other mechanics do. Use a pipe wrench on the pulley and a ratchet with a 15/16 socket. I have always used a air or electric impact to install the last 100K pulleys.

    It's definitely easier to take one off with an impact wrench...
    Wear a heavy leather work glove, grab the pulley and hit the nut with the impact wrench.

    Same process for installation.

    A 3/8 impact is plenty don't use a 1/2. You won't over torque it. I put them on with my bare hands holding the pulley and have done for 34 years 6 days a week. Gloves are a great idea if you are not comfortable for the first time!

    I have used a Snap on IM31 pneumatic for decades and now use a Snap on electric that works well. Almost any impact will work. Snap on is a ton of money but you might be able to find a deal on Ebay.
