This aftermarket gearbox shaft and pinion is made for compatible John Deere rotary cutter gearboxes using the Iberica gearbox style. It transfers power through the cutter gearbox and replaces the worn shaft and bevel gear set inside the drive assembly. Built to match OEM This part uses the original-style 15 tooth pinion shaft and 22 tooth bevel gear configuration. It is built to match the required gearbox type and tooth count so the gears mesh correctly when installed in the proper Iberica gearbox. Installation Installation requires opening the gearbox and transferring or replacing related bearings, seals, and hardware as needed. No modifications should be required when the gearbox type matches, but standard gearbox service practices should be followed for alignment, backlash, and lubrication. .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; } }
