5. Operation
The Speedway Motors Hurst Street Super Shifter provides a short-throw, positive shifting experience. Proper operation ensures longevity and performance.
- Engage the clutch fully before attempting to shift gears.
- Apply firm, deliberate pressure to the shift knob to engage the desired gear.
- Avoid forcing the shifter into gear, as this can damage the transmission or shifter components.
- Ensure the vehicle is stationary and the clutch is engaged when shifting into reverse.
6. Maintenance
Regular inspection and minor maintenance will help ensure the optimal performance and lifespan of your shifter.
- Periodic Inspection: Annually inspect all bolts, nuts, and fasteners for tightness. Check for any signs of wear on the shift rods, bushings, and clips.
- Lubrication: Apply a small amount of high-quality grease to the pivot points of the shifter mechanism and the ends of the shift rods where they connect to the transmission levers.
- Cleaning: Keep the shifter mechanism free from dirt, debris, and excessive grease buildup. Use a clean cloth to wipe down the chrome stick.
- Bushing Replacement: If the nylon bushings show signs of excessive wear or play, replace them promptly to maintain shifting precision.
7. Troubleshooting
This section addresses common issues that may arise during or after installation.
| Problem | Possible Cause | Solution |
