Maybe fighting a non-problem but I would like make another stab at getting a balance of reasonable pedal pressure to throw. I have a small input toploader and I'm running a McCleod pressure plate #360821.
McLeod Racing - Diaphragm Pressure Plates
I have a McCleod small input throw out fork I got from Brent.
I have the Quicktime bellhousing and I installed the 1/4 inch spacer under the fork mount to maintain the fork towards the front of the bellhousing opening.
The car came with a 3/4 Tilton master but when the throw seemed long I switched to a 7/8 master. The 3/4 master looked like it had some scoring although I had only cycled it a few times. The pedal pressure was heavy before and I didn't notice a large increase. It did disengage with a shorter stroke but some of my initial problems may have been from pedal placement and adjusting the slave cylinder rod clearaces sufficiently.
Not sure what ERA is providing for a Slave Cylinder size with a 3/4 inch master - hoping Bob P. will weight in on this for clarity.
Couple things I'm pondering:
1. I had ERA splay my pedals out for me.
I have a hard time just stabbing one pedal at a time even with this setup (size 12s) but as a question for Bob again - I wonder if this splayed set up has been associated with any higher clutch pedal operation? It obviously puts a pretty good eccentric load on the pedal shaft bearing.
2. I have a spacer under the slave which is probably necessary for the bent finger clutch and fork positioning. I have what appears to be, pretty good alignment with the clutch fork when the clutch is let out. But as the clutch arm is pushed back it will pivot out and the alignment will become more off-center. I'm wondering if I should shim under the slave spacer to angle it slightly to the outside so that it won't experience quite as much side loading as the clutch is pushed in?
It's a bit strange that my fork clears my master cylinder with no problem considering that many have had to trim their fork on the end to clear cleanly. Maybe something to do with the small input fork????? I guess I will get my little camera scope out and look around in the bellhousing to see if anything is amiss.
Right now I'm thinking about ordering another 3/4 inch master cylinder (original was scored and leaking a little) and see if I can manage the longer throw and hope for lower perceived leg pressure.
It's not like I'm not use to a clutch. I drive a Mustang GT as a daily driver and have a 427 Corvette (also with a McLeod diaphram clutch).
Any thoughts, recommendations, suggestions on this would be welcome.
Thanks
Dan
