- Socket set
- Torque wrench
- Engine hoist
- Oil and oil filter
- Gasket set
- Timing chain and gears
- Engine assembly lube
- Safety glasses
- Mechanics gloves
Preparation for Installation
Before starting the installation process, ensure that you have a clean workspace and all tools at hand. It’s essential to read through the Scat stroker kit instructions thoroughly. Familiarizing yourself with the components will help streamline the installation.
Step 1: Remove the Engine
Begin by disconnecting the battery and removing any components that obstruct access to the engine. This may include the air intake, exhaust manifold, and any accessories mounted to the engine.
Using an engine hoist, carefully lift the engine out of the vehicle. Make sure to secure the engine properly to prevent any accidents during the removal process.
Step 2: Disassemble the Engine
Once the engine is removed, place it on a sturdy engine stand. Start disassembling the engine by removing the valve covers, intake manifold, and cylinder heads. Keep track of all bolts and components for reassembly.
Step 3: Remove the Stock Crankshaft
Next, remove the oil pan and timing cover to access the crankshaft. Unbolt the connecting rods and main bearings, then gently slide the stock crankshaft out of the engine block. Inspect the bearings for wear and replace them if necessary.
Step 4: Install the Scat Stroker Crankshaft
Carefully place the Scat stroker crankshaft into the engine block. Apply engine assembly lube to the main bearings before installation. Torque the main caps to the specifications provided in the kit instructions.
Step 5: Install New Pistons and Connecting Rods
With the crankshaft in place, it’s time to install the new pistons and connecting rods. Ensure that the pistons are oriented correctly, and apply assembly lube to the wrist pins. Torque the connecting rod bolts to the manufacturer’s specifications.
Step 6: Reassemble the Engine
Reinstall the oil pan and timing cover. Follow with the installation of the cylinder heads and intake manifold. Make sure to replace any gaskets and seals to prevent leaks.
Step 7: Install the New Timing Chain and Gears
Install the new timing chain and gears according to the kit instructions. Ensure proper alignment and tension to avoid timing issues that could affect engine performance.
Step 8: Final Checks and Reinstallation
Before reinstalling the engine, double-check all connections and torque specifications. Reinstall any components removed during the disassembly process, such as the exhaust manifold and air intake.
Step 9: Start the Engine
Reconnect the battery and start the engine. Allow it to idle for a few minutes, checking for any leaks or unusual noises. Monitor oil pressure and temperature to ensure everything is functioning correctly.
Step 10: Test Drive
Once the engine has been started and checked, take the vehicle for a test drive. Gradually increase speed and acceleration to evaluate the performance gains from the stroker kit. Note any changes in handling or power delivery.
Conclusion
Installing a Scat crankshaft stroker kit can provide significant horsepower gains and enhance your engine’s overall performance. By following these step-by-step instructions, you can ensure a successful installation and enjoy the benefits of increased power on the road.
