The Left Bearing Cover is a precision-machined component that secures the differential bearing on the left side of the housing. In the Rear Axle Final Drive Housing with Bearing Cover Assembly, it is made of high-strength steel with a corrosion-resistant coating. The cover features accurately positioned bolt holes and a locating dowel pin to ensure correct alignment and even load distribution across the bearing. Its precise fitment maintains the required bearing preload, which is critical for the long-term reliability of the Rear Axle Final Drive Housing with Bearing Cover Assembly.
The Right Bearing Cover is the symmetric counterpart to the left cover, securing the differential bearing on the right side of the housing. In the Rear Axle Final Drive Housing with Bearing Cover Assembly, it is identical in construction and finish to the left cover, ensuring balanced support and alignment. Both bearing covers work together to maintain the correct bearing preload and shaft alignment, which are essential for smooth gear operation and extended bearing life. The covers are designed to be easily installed and removed, simplifying maintenance of the Rear Axle Final Drive Housing with Bearing Cover Assembly.
These high-strength hexagon head bolts are used to secure the bearing covers to the main housing. In the Rear Axle Final Drive Housing with Bearing Cover Assembly, they are manufactured from grade 10.9 alloy steel with a fine-pitch thread and a zinc-nickel coating for corrosion resistance. The bolts provide the necessary clamping force to hold the bearing covers firmly in place, preventing any movement that could affect bearing preload or gear alignment. Their precise length and thread engagement ensure that the correct torque can be applied, which is essential for the long-term reliability of the Rear Axle Final Drive Housing with Bearing Cover Assembly.
These precision-ground dowel pins are used to accurately locate the bearing covers to the main housing. In the Rear Axle Final Drive Housing with Bearing Cover Assembly, they are made of hardened steel with a close-tolerance fit that ensures precise alignment of the covers with the housing’s bearing bores. The dowel pins prevent lateral movement of the covers during installation and operation, maintaining the correct bearing preload and gear mesh. Their use eliminates the need for trial-and-error alignment, simplifying assembly and ensuring consistent quality in the Rear Axle Final Drive Housing with Bearing Cover Assembly.
The Rear Axle Final Drive Housing with Bearing Cover Assembly is manufactured from high-strength cast iron, providing exceptional rigidity and durability. Its robust design withstands the high torque loads and vibrations of the driveline, ensuring reliable performance over the life of the vehicle.
This Rear Axle Final Drive Housing with Bearing Cover Assembly includes all necessary components – the housing, bearing covers, bolts, and dowel pins – for a full installation. No additional parts are required, saving time and ensuring compatibility.
The use of precision-machined bearing bores and locating dowel pins ensures that the bearing covers are perfectly aligned with the housing. This maintains the correct bearing preload and gear meshing, reducing wear and extending the service life of the Rear Axle Final Drive Housing with Bearing Cover Assembly.
The Rear Axle Final Drive Housing with Bearing Cover Assembly is manufactured to the exact OEM specifications, guaranteeing a perfect fit on the Sitrak C7H. The precision-ground surfaces and correctly sized fasteners ensure a hassle-free installation, reducing downtime and labor costs.
