hydraulic clutch setup problem

I have a southwest speed hydraulic throw out bearing I installed on a ford T-5 transmission. Im using a wilwood 3/4" bore master cylinder and its not moving the throwout bearing enough. The southwest speed throwout bearing papers says not to use anything but a 3/4" master cylinder, so im not sure what to do. Should I move up to a 7/8"? I bleed the system correctly, and seem to have enough pedal travel. any idea's?

Check your clearances on that hyd throwout bearing as they do not have a whole lot of throw to them..You may need to do some shimming to get it setup right..There is I think a special tool to do that with..My old mind is foggy on that point..

Good Luck

Here's a link to a thread on another site that might help. Different setup but the info is good.

If shimming the bearing is not the issue...Can you drill the pushrod hole about 1/2" lower on your pedal to increase the motion ratio? I like to set things up so the pedal will push the piston throughout it's entire stroke allowed by the master cylinder. You may need to move your clutch master cylinder so as to keep the pushrod going in straight. You can also make an angled shim to put under the mount to get everything lined up.

Just a suggestion.
