Above are two pictures (before and after) of a Westerbeke 44A where a customer took advantage of ZRD's expertise to install a custom built externally regulated ZRD 120amp alternator using a ZRD custom designed (crafted) adjustment arm for tensioning. It is driven by dual 3/8" belts and pulleys. The before photo shows the Westerbeke original installed, standard 50 amp, internally regulated alternator. A close look at the after photo will reveal that the engine PTO also has two additional 1/2" sheaves available for future expansion to drive an additional engine driven accessory such as a ZRD Second (dual) High Output Alternator or a hydraulic pump. Increased output and unique problem solving solutions are what customers expect and receive from ZRD on a daily basis. |
