    So I dialed in my bellhouse and it came up with 12 O’clock is reading 12, 3 O’clock is reading 13, 6 O’clock is -1, and 9 O’clock is 0 where I started. So it looks like I need .007 offset dowel. Anyone else have this issue and where did you get your dowels from? Does a GM dowel fit a 225. Or is there a specific Buick dowel?

    You can get offset pins at Summitt. Can't remember the OD. Honestly .007 isn't terrible and within tolerable spec for a T18. Personally I wouldn't futz with it.

    Well with my T90 transmission it was grinding and since I took everything apart to fix it I might as well try to line everything up. You seen the previous picture of the pilot bushing? It was suggested by others that I should dial it in. So if it will bring it closer to center why not. Right?

    Just for reference - your pilot can get mangled from a couple different things and dialing it center is just one of them. I've seen perfectly dialed setups get chewed by having an issue with the tranny input bearing and/or the needle bearings in the top cluster having an issue.. on the T90 specifically, its the ones between 2nd and 3rd as well as the input and output bearings that can cause issues. Just a bit of wabble over time can be catastrophic on the pilot bearing.

    I’ll take that into effect. But for update I have reinstalled the T90. With new pilot bushing/clutch plate (in correct way as identified on plate itself) dialed in bell housing and pressure plate torque to spec according to manual. So with everything torque to spec and everything installed it should be able to change gears. Now I may have to adjust the plunger on the 3/4 Novak hydraulic clutch but am going to start out about half way out and press the clutch to see if any play before it hits the dia. Style clutch. Also have pivot ball adjusted out further as well. Crossing my fingers.. I’d be lost without a paddle if this fails.

    Went to go out and start the jeep, had a dead battery. I feel as though the clutch fork has at least 1” of movement on outside from Novak plunger to fork. But I can push pedal to floor and about 3/4 to the floor I don’t know if fork is moving anymore/less. But not sure if it’s engaging the clutch. I ordered a adjustable TO bearing from Mcloan or something 1.375 ID because Novak may be back ordered for 10wks. I am having doubts so that’s why I order the bearing. I will be trying it once the battery is charged today. I will update you sooon. I appreciate the question for update, sometimes i think I write in here and get nothing back but many do give great advice. Thank you all.. update soon..

    Rest assured that we are always watching and reading (two fingers my eyes to your eyes).
    Even though some (like me) may have nothing to add to your situation.
    The eyes are always watching.

    I asked because now I'm having my own questions about the Novak system. I just finished the install and tested mine and I was not able to shift while running the engine. Is there even enough travel in the system to fully disengage the clutch? I recently read, on Novak site, that the travel on a 3/4' slave will be the exact same as the travel on the 3/4" master. - Makes sense. So I just measured the travel on a brand new YJ master and it is real close to 1.5" Is that enough to fully engage / disengage the clutch on a V6?

    I appreciate it greatly. You all have been there since the beginning of my “Smallville” operation on my 62 Cj5/A1. Never done anything like this in my life and you all have shared with me how to do things. Thank you all and thank you to the site and builder of this.

    I know my pedal travel is just about 6” and my fork is just about 1” and I wasn’t getting any engagement from clutch. I may be getting the adjustable TO bearing to see if I can get more on the diaphragm type clutch plate

    I cant imagine that 1" at the fork is enough to disengage the clutch.

    The fork is just about all the way forward on bellhouse, pivot ball is almost fully extended, and Novak plunger is extended as well. Don’t know how to get more with the kit that came with Novak (hydraulic clutch,fork)

    So I got the battery charged and started it up. (Rough) but got it. Let it run for a bit. Then tried shifting.. NO GO. Grinds in R & first. Can go in second/third but jeep no go. Last option is the adjustable throw out bearing. If that doesn’t work. Then I have no clue!! Everything was put on to spec, aligned, and pretty much new besides flywheel and pressure plate because they worked and looked fine all day long when I had them out. Just have no idea what else it can be. And from previous post from everyone, the only thing left is the TO bearing.
    How much movement should the TO bearing have to travel? I have the bearing just about touching the pressure plate so when I press the pedal it should press into the diaphragms fingers..

    Second and third. It goes in but like no gear there or stalls when you try to go?

    Grinds in first and reverse. so that just seems like your not getting enough clutch. It pretty much should be the same in the gears.

    Is your transfer case in neutral? It sounds like the clutch is dragging so it doesn't want to got into the non-synchronized gears. But if it's dragging when shifting gears, it should be engaging when the clutch is let up.

    That might be why it’s not stalling out in second. So when you engage the TC it likely grind going into any gears.

    Yeah, I would think so.
