ATP 111002 "AWD" Disconnect... or is it?

[DirtyBacon04]

Well, I've discovered something rather... unexpected. I'm not sure whether or not I'm mad.
I installed the ATP 111002 (AWD disconnect assy)about 2 years ago. It had a good seal and grease from factory so I never opened it. I cracked it open today to inspect and regrease and found something that confused me at first... See if you can spot what's wrong with this "AWD" unit!





That's right, folks. The 111002 contains the normal fork/gear combination as a standard splined disco. Only difference is the inboard half of the case has a raised plug where the fork sits (where the actuator mounted), essentially doing the "redneck awd mod" that a few have done.



Initially I was furious. But then I was trying to figure out why I was mad... The purpose of the change was for an upgrade in durability, and I've beat the shit out of this rig and it never failed. I didn't even notice it was different until 2+ years later when I opened it for normal maintenance. I suppose once you take out the fork syncing the gears of different speed, which is the destructive action, this is just as reliable.

So I guess this post is just to inform people that if you DO purchase the ATP 111002 "AWD" disco, this is what is actually in there. Seems like the only difference between ATP 111001 (4wd) and 111002 (AWD) is the outer case. Hmmm.

Greased up and back in!



PS: My big tip is every time you install a CV, coat both splines w/ anti-seize (if you're not, already). When I removed mine today, I didn't need a single tool to free it from the disco. 2 or 3 pulls on the tripod housing, it popped loose. great success

Interesting, good to see it's holding up! Another vote for anti seize on the splines, makes a big difference down the road

Fascinating. How was the amount and condition of their grease?

[DirtyBacon04]

Well there was certainly a lot of grease in there. After 2 years, it got pretty dry, as you can see. In the second picture at the top center, you can see the pile of grease that I pulled out. Dry enough to pick up and it not leave any stain on the cardboard. Still slick on the gears and probably could've lasted a few more months.

Odd, I guess at their lower volumes, they wanted to keep their part numbers down and instead just machine the tooled outer half differently to account for the functional difference.

I bought the same one as you. I opened mine up before I installed it. Check it out.

To save everyone else the read: c0a8l0v6i8n9's unit came with the sleeve not the fork/gears.

Oh well. I'll just keep it as is. No reason to change it now.

Bacon, yours must have been an older version, I wonder if you contacted ATP if they would send you a new sleeve for a small charge... you know, if you really wanted it.
