High quality aftermarket 12 volt 70 amp alternators fit all versions (including marine) of Perkins 4.107 engines set up for a 'three lug' mounted alternator. The adjuster arm securing bolt is at a 120 degree angle to the mounting arms as can be seen from the photos and diagram and note that the mounting bolt is on the right or left (see photos). Options
- The standard alternator takes the earth (-) connection from the mounting to the engine block. Whereas the 'isolated earth' alternator requires a seperate cable to supply an earth.
- Supplied with cooling fan and pulley for either 12mm (7/16" inch) or 13mm (1/2" inch) alternator belt.
- Electrical output connections are for battery (+), alternator warning lamp and an AC terminal for a tachometer.
We include with the kit a packet of the correct electrical spade connectors and also a wiring diagram to help with fitting.
These alternators are manufactured by Prestolite Electric, USA based and a world leader in automotive charging systems. They come with a standard 12 month warranty.
