I'm almost done gathering parts for a 4-speed swap and I'm trying to mock up my hyro slave cyl.
I've run into a little issue where I'm not sure where in the range of motion the clutch fork goes. I can figure out the release distance from the flywheel position but I need to know how far into the bell housing the flywheel sits.

Hi Player1,

When I made a swap of an 833OD I had a block and crank attached to a flywheel, with a clutch, bell, TOB, and tranny all attached. I was trying to figure the stroke length to release and engage clutch disc from flywheel, and was using a pull slave, so I wanted to be sure the slave had long enough stroke to do the job.

I am uncertain I understand your question is why I say what I did to start. It sounds as if you are after the measure of how far the clutch fork has to move inside the bell from loose when clutch is engaged to tight against clutch fingers when clutch disc is separated from the pressure plate. Is that right?

How far the fly goes into the bell is not such a useful measurement because you would still need to subtract that from the stroke to get what you want. To establish the stroke all you need is a fixed external measuring point. I just bolted a flat steel plate to one of the tranny to block bolts. Then put a lever on your fork and with the tranny in a gear, use one hand to try to spin the output shaft. With the other hand pull your fork to you until full release or first release occurs, whichever you want. Hold the lever and measure the fork to plate distance with the hand that was on the output shaft, or block the fork with an adustable threaded rod.

I will look in my notes and PM you the distances I had, and I used a wilwood pull because it had the longest stroke.

Yep, i'm looking for the " from loose when clutch is engaged to tight against clutch fingers when clutch disc is separated from the pressure plate" measurement, but I figured I could get to that point if I knew how far inside the bell the flywheel sits when it's all bolted together. I didn't expect anyone had the exact numbers.
I built the bracketry setup to get me into the ballpark and I figured it would be close enough but the fork has an awfully long throw. I mean if I bottom the fork back against the trans case it has to travel about 1 1/2 inches before it hits the fingers if I'm guessing the position of the flywheel correctly.
I suppose I could wait till I get it all bolted together but I was hoping to do as little fabrication during the install as possible. PITA to mock stuff up when its under the car...and after thinking about it (writing this post), yes it would be easier to use some sort of threaded pusher to get the range set rather than bottoming out the slave and hard mounting it in what could be the wrong position..that's what I get for trying to make it harder than it needed to be.Thanks again
