Greetings, Everyone - Posting this on both sites as I am stumped:
I've tried to lurk and search since joining the forum in an effort to avoid creating duplicate threads, but I'm stuck with a problem here.
Parts involved:
Ford Racing Bellhousing M-6392-E https://www.summitracing.com/parts/FMS-M-6392-E
RAM HDX 10.5" Clutch Kit 88794HD https://www.summitracing.com/parts/RAM-88794HD
Ford Racing Super-Duty T-5 Transmission M-7003-Z https://www.summitracing.com/parts/FMS-M-7003-Z
Summit Racing Clutch Fork SUM-700105 https://www.summitracing.com/parts/SUM-700105
Wilwood 13/16 Clutch Master Cylinder 260-11972 https://www.summitracing.com/parts/wil-260-11972
Rosehill T5 Hydraulic Clutch Bracket Kit w/CNC 305 Push 7/8" Bore Slave Cylinder Rosehill Performance Parts (http://www.rosehillperformanceparts.com/Products_Page.htm#-:T5%20Hydraulic%20Clutch%20Bracket%20Kit:-)
The Problem:
Installed all parts and bled the hydraulics for the clutch. I'm getting a solid 1 + 1/8" of travel from the slave, which from everything I had read, should be enough.
If you picture the available travel for the clutch fork within the opening in the bellhousing, the clutch will not open until the last quarter of that range, leaving about 1/2" of distance before the clutch fork would contact the front of the bellhousing. In and of itself that could be fine. But...
I'm having to preload the throwout bearing by the better part of an inch under load (by running the nut and ball on the threaded rod forward) to get to a spot where the slave's throw ability is in the right range to make the clutch open.
From anything I have ever heard, read, witnessed, the throwout bearing should have 1/8" of play off the face of the clutch fingers, or at the most just very slightly touching...but certainly not an inch of pressured load up against them. It's as if the clutch requires wayyy too much throw to open up.
Does anybody have any idea at all on what I've managed to muck up here? I know there are many many people running around with hydraulic clutch setups on cobras and mustangs.
Any help is greatly appreciated in advance!
