3.4 swap into 1985 Jeep Cherokee questions?

But that one according to the Parts America site has the wrong number of teeth.

**Ok I tried looking up the flywheel for a 1988 FI 2.8 blazer and it calls for a flywheel with 148 teeth...the same amount as my 1985 jeep. So since the blazer was fuel injected I assume this means it was a model that was internally balanced. Is this correct, and will this bolt up to and fit my jeep with no modifications. Also I have an AX5 tranny if that makes a difference.

Yes a blazer/pickup flywheel will work. But that link you gave us shows an external balance flywheel.

Labeling stuff is for dorks.

I had a chance to work on the jeep for a few hours tonight. I am getting pretty close to being able to pull the engine. All of the acessories are off now, most all of the wiring/vacuum is un hooked, the throttle cables are disconnected, the starter is out, the exhaust is cut off, the tranny is drained. Here are a few pics. When I have a few more hours after work one day I am going to try to yank the engine. I would like to disconnect the tranny before I pull it, do you guys know how hard it is? From looking at it the top bolt closest to the firewall/tunnel will be the only real pain. Any thoughts on this? Anyway here are a few pics, feel free to post thoughts or advice.



**oh yeah, check out the motor mount on the right (pass.) side...it has no rubber above the bolt, I think it is time for some new mounts

No. The Camaro wheel was a strange one. It has a very large dish in it. You need the S-10 style flywheel.

Same here. That page was too unorganized for me to read all the info though. A new flywheel will work fine.

do you think the camaro/firebird 3.4 flywheel will work fine? Because that will probably be cheaper than having the machine work done.

it has an explanation on why u want to use the externally balanced flywheel and have it neutrally balanced

maybe I am blind but I don't see what you are talking about. I read the part about them having the flywheel neutrally balanced, but I do not see where they are saying you have to do this as opposed to buying a newer flywheel that is already neutrally balanced.

I may give it one more shot then before I take it to a shop. I am going to have to drop down in drill bit size if its going to work, because there is not much material left.

Yep, I know where you're at. I broke a few bits.

[cardana24]

Yeah, you can't drill the extractor itself, gotta remove material around it. My 3.4L had a couple broken studs in it too.

Why do you need to get it out? Isn't that in the engine you're replacing?

I had that problem when I used the wrong size extractor and broke the tip off. I destroyed some drill bits drilling around it the broken extractor and chiseling it out so I could re-drill and use the correct size. Wasn't fun, but I got it out.

I need to get it out because it's on the 3.4. I have not even tried to pull the manifolds off of the 2.8 and to tell you the truth I doubt I will. I will probably just cut the y pipe so I can take the oil pan off.

as for the stud, I tried drilling it again after I broke the extractor in it and I could not drill it, no material was coming out at all...that's when I gave up.

If you have broken and easy out off in the bolt then you pretty much limited yourself to welding a piece of metal to the stud and trying to get it out. Welding something on will also rapidly heat the broken stud hopefully breaking it free. My Trooper also has a broken bolt on the exhaust manifold where the PS pump bracket mounts.
