Here's a general outline. Specific steps might vary slightly depending on your exact model and any aftermarket modifications. Consult a repair manual specific to your 1986 Jeep Cherokee 2.8L 5-speed for detailed instructions and diagrams. These are invaluable.
1. Preparation:
* Gather tools: You'll need a socket set (metric), wrenches, a bleed kit for the clutch hydraulic system, a catch pan for fluid, a new slave cylinder, possibly a new clutch line (if damaged), penetrating oil (like PB Blaster), rags, and gloves.
* Safety first: Disconnect the negative battery terminal. Support the vehicle securely on jack stands. Chock the wheels.
* Fluid drainage: Place the catch pan under the transmission to collect any spilled fluid.
2. Accessing the Slave Cylinder:
* Remove the inspection cover: Locate the slave cylinder on the transmission. Usually, you'll need to remove an access panel or cover to reach it. This might involve removing some bolts or fasteners.
* Disconnect the clutch line: Carefully disconnect the hydraulic line from the slave cylinder. You might need a wrench to loosen a flare nut connection. Have a rag ready to absorb any spilled fluid.
3. Removing the Slave Cylinder:
* Unbolt the slave cylinder: The slave cylinder is bolted to the transmission. Usually, there are one or two bolts holding it in place. Use penetrating oil if the bolts are stubborn. Remove the bolts carefully.
* Remove the slave cylinder: Once the bolts are removed, the slave cylinder should come out relatively easily. Note its orientation and any seals or other parts that might be easily lost or damaged.
4. Installing the New Slave Cylinder:
* Clean the mounting surface: Clean the mounting surface on the transmission where the new slave cylinder will go. Remove any old gasket material or debris.
* Install the new slave cylinder: Carefully install the new slave cylinder in the same orientation as the old one. Tighten the bolts to the manufacturer's specified torque (check your repair manual).
* Connect the clutch line: Carefully reconnect the hydraulic line to the new slave cylinder. Be mindful of not over-tightening the flare nut connection.
5. Bleeding the Clutch System:
* Reconnect the battery: Reconnect the negative battery terminal.
* Bleed the clutch system: This is crucial to remove air from the hydraulic lines. Use your bleed kit. The process typically involves opening the bleeder valve on the slave cylinder while someone slowly depresses and releases the clutch pedal. This forces air bubbles out. This step is detailed in your repair manual. It's usually a two-person job.
* Check for leaks: Inspect all connections for leaks.
6. Reassembly and Testing:
* Replace access cover: Reinstall any access panels or covers removed earlier.
* Test the clutch: Start the Jeep and test the clutch pedal. It should have a firm feel and the clutch should engage and disengage smoothly. If the clutch pedal feels spongy or the clutch slips, there's likely still air in the system and you need to re-bleed the system.
Important Considerations:
* Repair Manual: A repair manual specific to your 1986 Jeep Cherokee 2.8L 5-speed is essential. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Clutch Replacement: If the clutch itself is worn or damaged, this is a good time to replace it, as the transmission needs to be removed or at least partially disassembled to access it.
* Professional Help: If you're not comfortable performing this repair, it's best to take it to a qualified mechanic.
This is a general overview. Always consult a repair manual and prioritize safety. Improper repair can lead to damage to your vehicle or even injury.
