This aftermarket bearing arm double pulley kit fits John Deere X Series mower deck drive systems. It supports the belt and pulley arrangement on the deck so the blades can run properly and stay aligned under load. Built to match OEM This replacement kit is made to match the original bearing arm and double pulley layout for the correct deck application. The mounting points, pulley position, and bearing function are intended to line up with the factory-style setup without changing the deck. Installation Installation is a straightforward deck service job for a DIY mechanic with normal hand tools. Remove belt tension, take off the worn assembly, and bolt this kit back into the existing location; no cutting or fabrication is required when used on the correct application. .product-description-v2 { font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif; color: #1d1d1d; line-height: 1.55; max-width: 720px; } .product-description-v2 > div { margin-bottom: 18px; } .product-description-v2 h3 { font-size: 16px; font-weight: 700; color: #1d1d1d; margin: 0 0 8px; } .product-description-v2 p { margin: 0; font-size: 15px; } @media (max-width: 768px) { .product-description-v2 { font-size: 15px; } }
