The Chelsea 645ZJUX-4KA or 645ZJUX4KA is a 6-bolt PTO assembly that mounts to a 6-bolt transmission opening. It positions the PTO at a 45° downward angle, an offset designed to help clear chassis components and eliminate common interference problems in tighter installations. The unit shares its input gear architecture with the Chelsea 442 Series, making it a familiar choice for shops already working with that platform. A link-bracket or secondary hardware conflict? This mounting geometry is often the fix. Call us to confirm proper fit for your application, Pro Gear and Transmission carries genuine Chelsea PTOs.
