Are you really still running M28 stuff, or was that a typo and shoulda been M18? I love M28 but Milwaukee has virtually walked away from it in the domestic market.
Yeah i have a handful of older M28 stuff. The drill is too heavy but i love my circular saw and big impact. I invested a few hundred bucks in batteries a few years ago so I'm not ready to give up on them

So only got a couple hours in today. Dropped shafts and y-pipe. Jeep does use a pretty impressive thread lock on the shafts. My M12 impact couldn't do it all, had to break out the M28 for a few fasteners.

The kit does include a throw out bearing
Probably the "red" Loctite used on the steering box nut. A little heat works great to break that stuff down so its easier to unscrew/unbolt. We use it here and there at work and since I do the rework I had to come up with ways to get things apart that werent design to come apart:)

So here's the dual mass flywheel. Not a fantastic design in my opinion all riveted together. I guess it's supposed to separate the engine balancing portion from the piece making contact with the first clutch disc?

Whole assembly was in terrible condition, lots of heat burns.

How much of a bear is the 6sp, I mean does it seem overly heavy or not too bad?

How many miles? I have seen worse but that is not great lol I am no expert though. What do the springs look like? What’s the clutch look like?

It was a bit much for me but my workout regiment consists mostly of 12oz curls...

Maybe 150 lbs? I used my floor Jack. I dropped the t-case by hand but kinda ended up half pinned under it :facepalm:

It's near identical to the AX15 in my old TJ, just longer. If you've done one of those, your good here

37,000 miles. Most not very hard miles. I think the twin clutch introduces a whole bunch of unnecessary slip and heat

What’s weird is twin discs are used in higher hp/ torque applications. Aftermarket sells them to trucks who tow heavy as well.

Thanks for sending all the pictures. Very interesting to see.

You dropped the t case separately?

I think if the discs engaged simultaneously like a multi disc clutch pack in an automatic transmission drum, that would work well, but the staggered engagement of this unit makes no sense.

Not being a muscle-man, and working by myself, i did drop the t-case separately. With a better transmission jack (I own one but I left it at my father's house and travel is difficult now with the restrictions) they could be slid back together instead of removed.

What exactly is meant by dual mass? Is it made out of two different materials that are bonded together?
No, a dual mass flywheel is usually made from two pieces (inner and outer). The crank connects to the inner and the clutch rubs the outer. There are springs between the two. They are usually used to dampen torque spikes in engines with large spikes like diesels. Here's a link to wikipedia with some illustrations.
