Description

Product Overview
The ROTOR DRIVE COUPLING 17SPL is a universal joint drive shaft coupling, specifically a splined shaft sleeve. Its core function is to efficiently and reliably transmit power from the tractor’s power take-off shaft to the combine harvester’s threshing drum system. It serves as the “throat” component in the harvester’s drivetrain, connecting external power and internal operations.
• Core Model: ROTOR DRIVE COUPLING 17SPL
• Original Part Number: 1345307C1 (This is the official Case IH standard part number)
• Compatible OEM Numbers: It is often compatible with related or alternative models such as 1345308C1 and 1345309C1, but please ensure that 1345307C1 is used when purchasing.
Key Functions and Features
1. Power Transmission: As the hub of power transmission, it withstands the enormous torque from the engine, ensuring the threshing drum rotates stably at the required speed to complete the threshing and separation operations. 2. Spline Connection: “17SPL” indicates a 17-tooth spline. This design ensures a highly precise fit with the driveshaft, enabling high torque transmission while allowing a certain degree of axial movement to accommodate slight vehicle movement and vibration during operation.
3. Protecting the Drivetrain: The high-quality coupler absorbs instantaneous impact loads, protecting the tractor’s PTO shaft and the harvester’s internal components, such as the roller and bearings, from damage.
4. Wear-Resistant and Durable: Typically made of high-strength alloy steel and heat-treated (such as quenching and tempering), it has a hard, wear-resistant surface and a tough core, ensuring a long service life.
5. Precise Fit: Designed specifically for Case IH series harvesters, the mounting dimensions, spline specifications, and performance parameters are identical to the original parts, ensuring optimal equipment operation. Applications
