Buying Guide for Speedometer Gears for Turbo 350

When I decided to upgrade my Turbo 350 transmission, understanding speedometer gears became essential. These gears play a critical role in ensuring my speedometer reads accurately, especially after modifying my vehicle. Here’s what I learned along the way.

Understanding Speedometer Gears

Speedometer gears are crucial for converting the rotation of the transmission into a speed reading on my dashboard. The Turbo 350 uses these gears to determine the vehicle’s speed based on the driveshaft’s rotation. It’s important to select the correct gear to ensure my speedometer reflects accurate readings.

Factors to Consider

Before I made a purchase, I considered several key factors:

1. Differential Gear Ratio: The ratio of my vehicle’s differential affects the speedometer reading. I needed to know this to choose the right gear.

1. Tire Size: The size of my tires also influences speedometer accuracy. Larger tires can cause the speedometer to read slower than actual speed, while smaller tires can make it read faster.

1. Transmission Type: Understanding that I was working with a Turbo 350 was crucial. Different transmissions may require different gears.

1. Desired Accuracy: I wanted to ensure my speedometer was accurate at various speeds, especially since I drive on highways.

Types of Speedometer Gears

I found that there are several types of speedometer gears available for the Turbo 350:

1. Plastic Gears: These are lightweight and often the most common. They are suitable for most applications but may wear out over time.

1. Steel Gears: More durable than plastic, steel gears can withstand higher torque and heat. They are ideal for performance applications.

1. Color-Coded Gears: Many speedometer gears come color-coded to indicate their tooth count. I learned that matching the color could simplify my selection process.

Installation Process

Installing speedometer gears was straightforward for me. Here’s a brief overview of the steps I took:

1. Access the Transmission: I had to remove the tailshaft housing to access the speedometer gear.

1. Remove the Old Gear: Carefully, I extracted the old gear, taking note of its type and tooth count.

1. Install the New Gear: I ensured the new gear fit snugly in place before reassembling the tailshaft housing.

1. Test the Speedometer: After installation, I took my vehicle for a test drive to verify the speedometer’s accuracy.

Final Thoughts

Choosing the right speedometer gear for my Turbo 350 was a rewarding experience. I learned that understanding my vehicle’s specifications, including differential ratio and tire size, was vital to achieving accuracy. Whether I opted for plastic or steel gears, I felt confident that I could enhance my driving experience with the right choice. Taking the time to research and install the correct gear made all the difference in my vehicle’s performance.
