Re: 3.7 underdrive pulley installed

I am curious. You said it took you a while to figure out how to install this. Does that mean it was fairly complex? Or just not easy to grasp from the start?

Re: 3.7 underdrive pulley installed

Did you have to remove the fan or both fan and shroud to get this in? I understand for the 4.7 you had to remove both to get in there?

Re: 3.7 underdrive pulley installed

I didn't take any pics during the install but i can snap a quick one of the finished assembly if you guys would like.

The reason i said it took a while was beacuse of the special tool thats needed for the installation of the new part. The factory piece can be removed with a common three jaw puller but there is no getting around the need for a specialized tool for installation of the aftermarket part. The dealership wanted to charge me $250 for install (way too high in my opinion) or i would have had to buy the tool and it costs around $150 up here (hard to justify for a one time use tool). I know it can be rented through the Airram website but again,because of my location,that wasn't practical.
What i ended up doing was to buy 2 new damper bolts from the dealership, cost about $12 each, and gave them to a guy i work with who has his welding tickets and a nice mig welder at home. He cut and welded the bolts back together but made the entire thing about 2 inches longer. This worked great to pull the new balancer pulley onto the crank snout far enough, until i could use the original bolt to actually torque it down.
Other than the special tool the job isn't difficult and most anyone with decent ability should be able to do this job in an afternoon easily. You technically don't need to remove the fan shroud but for the 10minutes of extra time it takes to remove and reinstall later, it makes the job much much easier. It gives you room for an impact wrench rather than a ratchet, which makes removing the crank bolt waaaaay easier. Since the 3.7 only uses an electric fan, you can remove the shroud/fan assembly by just removing 4 bolts and unplugging one large wire connector.

Not sure as that was quite a while ago and i've traded off that truck so i can't even go and look. I just went to my local auto parts store and bought a few belts that were shorter, returned the ones that didn't work.
