However, if you're determined to proceed, here's a general outline. This is not a complete, step-by-step guide, and details may vary slightly depending on the exact engine configuration. Always consult a repair manual specific to your 1985 Ford Ranger 2.8L V6. A factory service manual is ideal.
1. Preparation:
* Safety First: Disconnect the negative battery terminal. Wear safety glasses and gloves.
* Gather Tools: You'll need a variety of tools, including but not limited to: socket wrenches, ratchets, extensions, torque wrench, timing gear puller, timing gear installer, harmonic balancer puller (likely), crankshaft pulley puller (likely), possibly a dial indicator for accurate timing setting, and a repair manual.
* Gather Parts: Obtain the correct replacement timing gears. Ensure they are the correct specification for your engine.
* Workspace: Work on a clean, well-lit surface with ample space.
2. Engine Access:
* Remove Accessories: You'll likely need to remove various components to gain access to the timing gears. This might include the:
* Radiator
* Fan shroud
* Water pump (possibly)
* Power steering pump (possibly)
* Alternator (possibly)
* Other belts and pulleys
* Remove the Timing Cover: This will expose the timing gears.
3. Timing Gear Removal:
* Lock the Engine: Critical! You must properly lock the engine to maintain the crankshaft and camshaft timing. The method for this varies; your repair manual will explain how to accurately lock the engine in the proper position. This prevents damage during the process. Failure to do this correctly can lead to engine damage.
* Remove the Timing Gears: Use the appropriate tools (gear pullers) to carefully remove the timing gears from the crankshaft and camshaft. Take note of their orientation and any marks to help with reinstallation.
4. Timing Gear Installation:
* Clean all mating surfaces: Thoroughly clean the crankshaft and camshaft surfaces where the gears will mount.
* Install new gears: Using the correct installation tools, carefully install the new timing gears. Make sure they are seated properly and are not damaged during installation.
* Double-Check: Ensure the timing marks align perfectly according to your repair manual's specifications. A dial indicator can be very helpful here.
5. Reassembly:
* Reinstall the timing cover. Use a new gasket if necessary.
* Reinstall all accessories: Reconnect everything you removed, ensuring all bolts are properly torqued.
* Reconnect the battery: Double-check all connections.
6. Verification:
* Start the Engine: Carefully start the engine and listen for any unusual noises. Check for any leaks.
* Monitor the Engine: After a short run, check for overheating or any other problems.
Disclaimer: This is a simplified overview. This process is complex and requires significant mechanical knowledge and specialized tools. Improperly performed, this repair can severely damage your engine. Refer to a repair manual specific to your vehicle and, if you have any doubts, consult a qualified mechanic. The cost of a professional repair will be far less than the cost of a damaged engine.
