Here's the process:
1. Preparation:
* Transmission Removal: The transmission must be removed to access the crankshaft and flywheel/flexplate. This is a major undertaking, requiring significant mechanical knowledge and the right tools. Consult a repair manual specific to your year and model Ram 1500.
* Cleanliness: Thoroughly clean the crankshaft mating surface and the flywheel/flexplate. Any debris will prevent proper seating and can damage the engine.
* Tools: You'll need a flywheel/flexplate alignment tool. This tool is *crucial* and ensures the flywheel/flexplate is correctly positioned on the crankshaft. It fits into the pilot hole of the crankshaft. Without this, you risk misalignment and damage. You will also need torque wrench and socket for the flywheel bolts.
2. Alignment and Installation:
* Insert Alignment Tool: Insert the alignment tool into the crankshaft pilot hole. This tool will project from the crankshaft, acting as a guide.
* Position the Flywheel/Flexplate: Carefully position the flywheel/flexplate onto the crankshaft, ensuring the alignment tool is fully inserted into the corresponding hole in the flywheel/flexplate. It should slide on smoothly. The flywheel/flexplate should sit flush against the crankshaft flange.
* Secure the Flywheel/Flexplate: Install the flywheel bolts (or flexplate bolts) and tighten them in a star pattern, gradually increasing torque according to the specifications in your repair manual. Do *not* over-tighten.
3. Torque Converter (Automatic Transmission):
* If you have an automatic transmission, the torque converter needs to be properly seated on the crankshaft pilot before installing the flexplate. There's typically a pilot bushing to ensure proper alignment. The torque converter should slip onto the crankshaft, with a positive engagement. This is where a helper can be quite beneficial.
* After the torque converter is fully seated, the flexplate bolts are secured.
4. Verification:
* After tightening the bolts, carefully inspect the flywheel/flexplate to ensure it is still aligned with the alignment tool. Any wobble or misalignment suggests an issue.
Important Notes:
* Repair Manual: A factory service manual specific to your year and model Ram 1500 is indispensable. It will contain precise torque specifications, diagrams, and procedures. Attempting this without a manual is strongly discouraged.
* Safety: This is a complex task requiring mechanical skill. If you're not comfortable performing this repair, take it to a qualified mechanic. Improper installation can lead to serious engine damage.
* Automatic vs. Manual: The process is slightly different for automatic (flexplate and torque converter) and manual (flywheel) transmissions. Make sure your steps are correct for your transmission type.
This is a simplified explanation. The specific steps may vary slightly depending on your vehicle's year and engine configuration. Always consult your repair manual for detailed instructions. If you are unsure about any part of this procedure, seek professional assistance.
