Many small Lugger marine engines and Northern Lights generators are equipped with a power takeoff (PTO) unit that can be used to drive accessories. Hydraulic pumps are a common use case for this PTO.
These PTOs are equipped with electric clutches to allow them to be powered or unpowered at will. This is convenient, but the clutches are a wear item that periodically require service. In this video we replace the clutch on a Lugger L844d auxiliary engine with 1036 hours on it. This same clutch and PTO also is used on the Northern Lights 12KW and 16KW generators.
