I bought a truck the other day that had a "new clutch" that "broke the transmission." Trans is fine, but what I've come to guess is the master cylinder was just hanging out of the trans where I assume it bolts in. Lots of crappy rubber-to-plastic splicing and I've not even found the "slave cylinder" yet. The only diagram I've found is very tiny, and I can't figure out what all I'm missing. According to the diagram, I've bolted the master to where the slave goes, and don't have a slave at all. I'm completely lost. Any ideas?

I can get pictures wednesday when I start working on this thing again.

After more research I found out the slave is inside the bellhousing, durrhurr, still doesnt explain how any of this actually works, some assembled pics would be great! :p

Edit..again...after even more research I found out that isn't even the right diagram and that there isn't really one showing the '84 toyo 4wd clutch setups...Don't really want to have to buy a new everything and drop the trans but I think I'll have to because if they muffed up the hydraulic system this bad imagine what they did to the rest of it.

The master cylinder on your truck will be exactly where it is in that diagram... (on the firewall) and the slave cylinder is totally different. In that diagram, the slave cylinder is inside the bellhousing but your 4 speed would have it outside on the driver's side. It pushes against the clutch release fork that also sticks out of that side of the bellhousing.

That is unless a newer trans has been swapped into your truck over the years.
 
After looking about it is the external, and I can reach inside the bellhousing and just flop the fork around freely, and the slave is missing a few parts, so looks like I'm ordering a new slave and dropping a trans soon as I get the engine running. It goes in gear and turns the engine over (we tried roll starting it) so I bet the "new" clutch is installed backwards.

Clicking relay but no crank, cranked when we jumped it then stopped doing that, so I'm replacing all positive terminals and wire to the starter now. Got a brand new starter to figure out it's the wires or the relay.

Relay is the only thing I won't have replaced in the starting system and even though it clicks I bet it's the issue.

No known spark yet, either, but the external contacts on the distributor were nasty so hopefully a quick cleaning fixed it. This truck's one heck of a project for me. It'll be worth it in the end, though.
