I don't know if I'd call it a "control system", but it's not that difficult. I did look in my paper manuals (Engine manual and both volumes of the Chassis and Body manual) for information, but found only job 03-410, Removal and installation of flywheel and driven plate, and job 03-420, Refacing flywheel, to be related to the manual clutch in any way. I thought I had seen something that at least talked about bleeding the clutch, but I cannot find that either! > The supply hose was leaking, so I did a field-expedite repair with an > incorrect hose.

So everything hydraulic needs to be looked at. The master cylinder for the brakes and its affiliated appurtenances are the more complicated part of the system. The clutch system has one master cylinder and one slave cylinder. The master cylinder is fed by a rubber/cloth hose from the rear section of the brake fluid reservoir. That goes through the firewall to the inlet of the clutch master cylinder. The outlet of the clutch master cylinder is connected to a hard line that goes through the firewall near to the bell housing. A short flex line jumps the gap between the body and the bell housing and connects to another hard line that goes to the slave cylinder, which actually does the work of pushing on the clutch actuator. The leak at the master cylinder can be due to the connection of the hard line being loose. That was the problem on our car when I found a brake-fluid-saturated (and ruined) driver's carpet. Both the master and the slave cylinders, of course, are subject to leaking gaskets and seals. I used to rebuild them, but don't anymore. Q has the parts you need. I found the best way to bleed the clutch is by pressure bleeding from the slave cylinder bleed screw. That has the potential of over-filling the brake fluid reservoir. Others say one should connect one of the front brake caliper bleed screws to the clutch slave cylinder bleed screw and pump the brakes. That risks ruining the brake master cylinder by running the seals onto a region that hasn't been much used and is therefore rough. Still others say start the car in gear and drive around until the clutch self-bleeds. I wish you success.
