I've just replaced the clutch and slave cylinder (M5OD) on my '93 Ranger 4.0l SuperCab. I'm having a problem bleeding the system. I've heard that they can be a pain in the butt.
Here's my problem:
I have two different procedures that totally contradict one another. The first one states that: "Before performing any service that requires removal of the slave cylinder, the master cylinder and pushrod must be disconnected from the clutch pedal. If not disconnected, permanent damage to the master cylinder assembly will occur if the clutch pedal is depressed while the slave cylinder is disconnected." Basically this procedure says: Open the bleeder and let it run.
The other procedure I have states (in short) to:
1. Disconnect the coupling at the transmission with a coupling disconnect tool
3. Remove cap and diaphragm and fill reservoir to the step
Do you have a visible bleeder valve at the transmission? I'm not sure the exact procedure for this, but pump the clutch in and out several times, then hold it on the floor. Have someone else crack open the bleeder valve for maybe a second. Repeat this until the pedal gets firm, making sure to keep the master cylinder full of brake fluid. Gravity bleeding it at first may help get it bled faster too. That's where you open the bleeder valve and just let gravity pull the fluid down the line from the master cylinder. Then bleed it normally to get the remaining air out. Hope this helps, I don't have a lot of experience with these clutches, but I think that might work.
