ACCT Rebuild Question

I rebuilt my ACCTs last night using new TOC springs and I'm wondering what others have experienced. The instructions call for one CW turn of the threaded shaft for preload, then threading the plunger assembly onto the shaft (while holding the shaft stationery, I assume) until the three-sided clip engages the three slots in the body of the ACCT. This sounds fine, but if done that way the plunger only extends about 1/2" from the body when it is fully extended. Does this seem right? I assembled one that way and then fitted on the bike. The end of the plunger didn't quite contact the cam chain guide inside the cylinder block, which leads me to believe that it won't hold tension on the chain.

How much should the plunger extend from the end of the ACCT housing for proper chain tensioning?

I did mine and found that also. I put them with no preload and worked fine.
Once you get them in give a twist to tighten them up with the adjust screw.
I have no noise from my ACCT's anymore.
What a great sound, ou should I say no sound.

It's been a little while since I did mine, but I seem to remember doing them a couple times before the plunger actually felt/sounded like it was doing it's job.
How far out it was at that point, I don't remember.

When I've redone mine, it's been the same - about a half an inch after the preload. A couple of weeks ago when I was redoing the springs on my '92, I felt like I'd overloaded the spring and the plunger was out only about 1/4 inch. I pulled it apart again, and focused on getting just 1 turn CW on the spring before screwing on the plunger. 1/2 inch was the result.

I stand's my ACCT from the left side of my bike. I just came back from the store and didn't have any coins in my pocket, so the bill should give you some sense of perspective. Too short - clatter, clatter, clatter. The right side, which I think was a little longer when I installed it, is quiet. In this case, the distance visible on the plunger body is almost exactly 5mm. I'm going to take it to 7mm and see if that eliminates the noise.

More shortly.
