Doug, I've kinda been along this trail with the CTB since last Jan, when I changed from a Toploader to a TKO 600. With my new Pond block, there was no hole for the ERA slave mount, and I didn't feel like drilling one, and several McLeod CTB users were around and saying good things. I am using the new version 1400-30 slip-on. And I did have to return the first one because it leaked at the swivel fittings
So the first install last Jan, I had a little trouble getting enough volume out of the 3/4" Tilton cylinder ERA sent me, had to unscrew the clevis about as far as it will go. Then my pedal is depressed all the way to the floor to get disengagement. This became a little better as it got broken in. Been having a lot of fun with it, but recently find myself replacing the disc and pressure plate for more robust stuff
The most important aspect of the installation is the gap betwen the CTB and the pressure plate fingers. McLeod install instructions explain this, and I did also in another thread recently. You have to measure the distance from the PP fingers to the outside of the bellhousing and compare it to the distance from the bearing face to the tranny face. There should be from .10" to .30" gap between the CTB and the PP (before the slave cyl is bled and pumped up).
You may or may not need the McLeod CTB spacer (I am talking about a spacer that goes on the TKO bearing retainer before the 1400-30 adjustment collar goes on). McLeod swore that I had to have one if I was using the transmission adapter (the 5/8" plate that goes between the tranny and the bellhousing). I didn't need it, it turned out.
McLeod says "bleed the master, bleed the slave, bleed the master again, and bleed the slave again." If you don't do this, you may have problems getting enough piston movement on the slave to get clean disengagement.
Keep us posted as you get into it, and we'll try to help. CTB's are a little complicated, each installation is unique, but they work great once they are dialed in ...
Don't hesitate to call Doug if you need advice from an absolutely reliable source!
