Review EATON Fuller Mainshaft Gear

The Eaton 12212 Fuller Mainshaft Gear is an essential component in the transmission system of heavy-duty vehicles, specifically those equipped with Eaton Fuller Roadranger or UltraShift transmissions. This gear is designed to provide efficient power transmission from the engine to the transmission, enabling the vehicle to perform optimally under various load conditions.

The Eaton 12212 Fuller Mainshaft Gear is manufactured using high-strength materials, such as heat-treated steel, to ensure durability and resistance to wear and tear. Its robust design makes it suitable for the demanding conditions encountered in heavy-duty applications, such as construction, logging, and transportation.

The gear features a full-float design, which allows each gear tooth to float independently, reducing the stress on individual teeth and increasing the overall longevity of the gear. This design also allows for some degree of misalignment between the input and output shafts, making it more adaptable to real-world conditions.

The Eaton 12212 Fuller Mainshaft Gear comes with precision-machined splines on both ends, ensuring a secure and reliable connection to the input and output shafts. Its tooth profile is designed to provide optimal meshing with the corresponding gears in the transmission, ensuring smooth and efficient power transfer.

The gear's dimensions are as follows: its length is approximately 22 inches (559 mm), its width is about 7 inches (178 mm), and its height is around 9 inches (229 mm). Its weight is approximately 120 pounds (54.4 kg), reflecting its robust and heavy-duty design.

The Eaton 12212 Fuller Mainshaft Gear is recommended for replacement when the original gear shows signs of wear, such as excessive noise, vibration, or difficulty shifting gears. Installing a new gear can help restore the vehicle's performance and reliability, ensuring that it remains operational for years to come.

When it comes to maintenance and installation, the Eaton 12212 Fuller Mainshaft Gear requires specialized tools and expertise. It is recommended that the installation be performed by a qualified technician to ensure a proper fit and function. Additionally, regular maintenance, such as lubrication and inspections, should be performed according to the vehicle manufacturer's recommendations to ensure the longevity of the gear and the transmission system as a whole.

1. Cost: Replacing the mainshaft gear in an Eaton Fuller transmission can be a costly investment, especially for those on a tight budget.

2. Complexity: The installation process for the Eaton 12212 Fuller Mainshaft Gear can be complex, requiring specialized tools and a high level of mechanical expertise.

3. Availability: Depending on the specific model and availability, it may take some time to locate and purchase a new Eaton 12212 Fuller Mainshaft Gear.

The Eaton 12212 Fuller Mainshaft Gear is an essential component of an Eaton Fuller transmission system, and its durability, ease of installation, and high-quality materials make it a worthwhile investment for those seeking improved performance and reliability. However, the cost, complexity, and potential availability concerns should be weighed carefully against the benefits before making a decision to purchase.
