GENERATOR
Single Generator
The single generator system consists of the generator mounted on the bottom right of the engine (diesel) or top center of the engine (gasoline). The
gasoline engines use a 115-amp generator with a 2.71:1 pulley ratio. The diesel engine uses a 135-amp generator with a 2.79:1 pulley ratio.
An option is available (diesel only) that includes a 200-amp generator with a 2.79:1 pulley ratio. The 2 generators are similar in appearance and use
the same connectors, making them interchangeable. Identification between the different generators can be carried out by referring to the generator
engineering part number and the master parts catalog.
Dual Generator
The dual generator package consists of an upper/lower generator system (diesel only). The 6.4L upper generator is a 120-amp generator with a 3.00:1
pulley ratio. The 6.4L lower generator is a 200-amp generator with a 2.79:1 pulley ratio. The upper and lower generators are not interchangeable.
