Here's a breakdown of the process:
1. Necessary Tools:
* High-quality harmonic balancer puller: A three-jaw puller specifically designed for harmonic balancers is crucial. Cheap pullers can slip and damage the balancer or crankshaft.
* Impact wrench (preferably air powered): This is essential for breaking loose the incredibly tight bolt. A breaker bar and cheater pipe might work, but it's risky and likely to result in stripped bolts or injured hands.
* Socket that fits the crankshaft bolt: Ensure it's the correct size and fits snugly.
* Crankshaft holding tool: This is absolutely critical. It prevents the crankshaft from rotating while you loosen the bolt. Without this, you risk serious injury and engine damage. This tool usually engages the flywheel teeth.
* Wrench (or socket) to fit the crankshaft holding tool.
* Torque wrench: For proper re-installation.
* Penetrating oil (PB Blaster, etc.): Apply liberally to the bolt several hours or overnight before attempting removal.
2. Procedure:
1. Disconnect the battery: This is a safety precaution to prevent accidental shorts.
2. Apply penetrating oil: Generously spray penetrating oil onto the crankshaft bolt. Allow ample time for it to soak in. You might even want to reapply it several times over hours or overnight.
3. Secure the crankshaft: Use the crankshaft holding tool to firmly secure the crankshaft. This is the MOST important step to avoid injury and damage.
4. Remove the bolt: Use your impact wrench to break the bolt loose. It will require significant force. Be prepared for resistance. If the impact wrench isn't strong enough, do NOT use excessive force with a breaker bar – you risk damaging the crankshaft. If it won't budge with the impact wrench, you may need professional help.
5. Remove the harmonic balancer: Once the bolt is out, use the harmonic balancer puller to remove the balancer itself. Follow the instructions that come with your puller carefully. Be gentle but firm.
6. Inspect the crankshaft: Once the balancer is off, inspect the crankshaft for any damage.
3. Reinstallation:
1. Clean everything: Thoroughly clean the crankshaft and balancer mating surfaces.
2. Install the balancer: Carefully align the balancer with the crankshaft and install it using the puller in reverse.
3. Install the bolt: Install the crankshaft bolt and tighten it to the manufacturer's specified torque using a torque wrench. This is crucial to prevent premature failure. Consult a repair manual for the correct torque specification.
Important Considerations:
* Professional Help: If you are not comfortable performing this repair yourself, or if you lack the specialized tools, it's strongly recommended that you take your vehicle to a qualified mechanic. This is not a beginner-level repair.
* Repair Manual: Obtain a repair manual specific to your 1997 Dodge Ram 1500 5.2L. It will provide detailed instructions, torque specifications, and diagrams.
* Safety First: Always prioritize safety. Wear safety glasses and gloves.
This process involves potentially serious engine damage if not done correctly. If in doubt, seek professional help. The cost of professional repair is far less than the cost of engine damage.
