This housing encloses and protects the reel-drive tine bushing on the combine header. It mounts at the end of the reel shaft, securing the bushing that supports the tine arm as it rotates through the crop. A damaged or missing housing allows debris to enter the bushing, leading to accelerated wear and eventual tine-arm misalignment. This component is formed from sheet steel to match the original profile, ensuring it seats correctly against the reel frame. When reinstalling, verify that the housing is fully seated and that the retaining fasteners are torqued to specification to prevent loosening during operation.
