Hey Pat,
I ran the McLeod diaphram pressure plate, with the Tilton hydraulic T/O and a Lakewood bellhousing in my last car. Formerly used a RAM hydraulic too. I don't think I ever really got it set up quite right with the diaphram pressure plate - after multiple tries. At first it worked really well...then over time as the pressure plate and clutch disc started to wear in, I needed to re-adjust the gap/clearance setting pushing the T/O bearnig on the trans input collar closer to the pressure plate each time. Eventually, the T/O bearing had to expand so far to disengage the clutch that it would allow the Tilton seal to pop out. i.e. overdriven. I only tried the RAM and Tilton T/O bearing setups though.
Anyhow, I wished I would have just went back to the 3-finger style pressure plate for the hyd. T/O setup (requires much less travel to disengage like .050 I believe). When it was working, I liked how the hydraulic TO setup functioned, very much - smooth and positive action.
Let me know how it goes and if you decided on a diaphram or 3-finger setup. I hope to learn where I went wrong from your guys experiences with it. Thanks.
