Since market introduction in mid-2002, patented Eco-Tech 14V high amp Alternators have been installed and used successfully by both original equipment and aftermarket fleet operators. Eco-Tech Alternators provide superior high output at idle performance (80% of rated output at idle) and unmatched efficiency have been experienced in diesel powered military boats; fire trucks; ambulances; utility company bucket trucks; school, shuttle and party buses; commercial fishing boats, and other applications where significant operating time at idle occurs at low engine speeds.

The J9-305-I model Alternator is a drop-in-replacement for C.E. Neihoff Series 600 altermators, which have a center-to-center measurement of 9” between the drive end pivot hole and the threaded adjusting hole. The J9-305-I Alternator has the standard measurement of 4” between the inside of both pivot ears. The existing alternator pulley will interchange and Alternator belts will align properly.
