1. Introduction to the OS Giken R200 Differential
The OS Giken R200 is a high-performance Limited Slip Differential (LSD) designed to enhance vehicle stability and traction. Manufactured by OS Giken, a renowned Japanese company specializing in automotive performance parts, the R200 LSD is engineered to distribute torque effectively between drive wheels, minimizing wheel spin and maximizing grip.
2. Benefits of Upgrading to the OS Giken R200 LSD
Upgrading to the OS Giken R200 LSD offers several advantages:
- Enhanced Traction: Improved power distribution reduces wheel spin, especially during acceleration and cornering.
- Better Handling: Provides consistent and predictable handling characteristics, crucial for high-performance driving.
- Durability: Constructed with high-quality materials, ensuring longevity even under strenuous conditions.
- Versatility: Suitable for both street and track applications, accommodating various driving styles.
3. Tools and Materials Required
Before commencing the installation, gather the following tools and materials:
- Floor Jack and Jack Stands: For safely elevating and supporting the vehicle.
- Wrench and Socket Set: Essential for removing and securing bolts.
- Torque Wrench: Ensures bolts are tightened to manufacturer-specified torque values.
- Differential Fluid: High-quality fluid compatible with the OS Giken R200 LSD.
- Gasket Maker or Replacement Gasket: For sealing the differential cover.
- Pry Bar: Assists in removing the existing differential.
- Drain Pan: To collect old differential fluid.
- Safety Gear: Including gloves and safety glasses.
4. Preparing Your Vehicle for Installation
Proper preparation is crucial for a successful installation:
- Safety First: Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the front wheels.
- Elevate the Vehicle: Use a floor jack to lift the rear of the vehicle and secure it with jack stands.
- Remove Rear Wheels: This provides access to the differential and associated components.
5. Removing the Existing Differential
Follow these steps to remove the current differential:
- Drain the Differential Fluid: Place a drain pan beneath the differential and remove the drain plug to empty the fluid.
- Disconnect Driveshaft and Axles: Unbolt the driveshaft from the differential and detach the axles.
- Remove Differential Cover: Unbolt and carefully remove the cover, exposing the internal components.
- Extract the Differential: Unbolt the bearing caps and use a pry bar to remove the differential assembly.
6. Preparing the OS Giken R200 for Installation
Before installing the new differential:
- Inspect the Unit: Ensure the OS Giken R200 LSD is free from defects or damage.
- Pre-Fill with Differential Fluid: Adding a small amount of fluid to the differential before installation can aid in lubrication during initial operation.
7. Installing the OS Giken R200 Differential
Proceed with the installation as follows:
- Position the Differential: Carefully place the OS Giken R200 into the differential housing.
- Secure Bearing Caps: Reinstall and torque the bearing caps to the manufacturer’s specifications.
- Reattach Axles and Driveshaft: Connect the axles and driveshaft to the new differential, ensuring all bolts are properly tightened.
8. Reassembling the Drivetrain Components
After installing the differential:
- Clean Mating Surfaces: Ensure all surfaces are free from old gasket material and debris.
- Apply Gasket Maker: If not using a pre-made gasket, apply a continuous bead of gasket maker to the differential cover.
- Reinstall Differential Cover: Attach the cover and tighten bolts to the specified torque.
9. Refilling Differential Fluid
Proper lubrication is essential:
- Locate the Fill Plug: Typically situated on the differential cover or housing.
- Add Differential Fluid: Using a fluid pump, fill until the fluid reaches the bottom of the fill hole.
- Secure the Fill Plug: Tighten to prevent leaks.
10. Post-Installation Checks and Adjustments
Ensure everything is functioning correctly:
- Lower the Vehicle: Remove jack stands and carefully lower the vehicle.
- Test Drive: Conduct a short drive to assess performance and listen for unusual noises.
- Inspect for Leaks: After the test drive, check for any signs of fluid leakage around the differential.
11. Common Installation Challenges and Solutions
Be aware of potential issues:
- Stubborn Bolts: Use penetrating oil to loosen rusted or seized bolts.
- Alignment Issues: Ensure the differential is properly seated before securing bearing caps.
- Fluid Leaks: Verify that all seals and gaskets are correctly installed and intact.
