The Chelsea 645XESX-4XX or 645XESX4XX is a power take-off assembly built around a 6-bolt PTO-to-transmission interface. Its defining design feature is a 45-degree downward angular offset, which repositions the PTO body to clear components that would otherwise create interference in tighter installations. Because it shares input gears with the Chelsea 442 Series, technicians already familiar with that platform will find the gear geometry consistent. The 645XESX-4XX mounts to a 6-bolt transmission opening, making it compatible with a range of medium- and heavy-duty transmission configurations that use that bolt pattern.
