I had ordered an installer tool for the harmonic balancer, but it seems the parts it comes with for jeeps do not work on the 2003 2.4L, due to the threads on the crank shaft starting down inside a bit, instead of at the face. I found the "official" tool, but it's $100 when you take into account tax and shipping. Best I can tell, it's a long M12x1.75 bolt, with a flange nut and a thrust bearing. I don't need the cup since I didn't pull off the timing belt sprocket. Curious if anyone else has experience with doing it on the 2.4L engines, and if I am wrong in thinking I can piece it together cheaper.

Looks like something I'd make if I was doing it.

Depending where you are located -

A loaner / rental from advance, autozone, oreilly, etc? Or a tool rental store like american rent all

All the ones they have available are like the one I had purchased, and are not long enough.

you should be able to get the harmonic balancer on enough to thread with the original bolt if you tap it (the balancer) with a hammer. then you just tighten it all the way down.

I've worked on (rebuilt) those 2.4's before. Use a skinny washer on the bolt to start it, then the original thicker one to finish, if putting it back on is what you're talking about.

This cost me about $20 since I couldn't find the bolt and thrust bearings locally. It worked like a charm. Way better than spending $100 on the tool. If anyone else needs this in the future, it's a 150mm M12x1.75 full thread bolt, M12x1.75 flange nut, and a 12mm thrust bearing. If you ever need to do the timing belt sprocket on the crank though, you may still want the tool with the cup that sets the depth correctly.
