Advance Chute Swing Gearbox Seal Tulsa

Advance Chute Swing Gearbox Seal Tulsa

This output seal is a direct replacement component for the Tulsa HFG430 chute swing gearbox (Terex part 12651) used to control the chute swing on front discharge concrete mixers. Each gearbox requires two of these seals to prevent gear lubricant from leaking and to protect internal components from concrete dust and debris. It is an essential maintenance item for older Terex Advance and Indiana Phoenix mixers equipped with the HFG430 drive, ensuring smooth operation of the chute swing mechanism.
