Balmar Yanmar 4JH3 Serpentine Pulley Kit

AltMount^®Serpentine Pulley Conversion Kits
Balmar’s Patented AltMount^® Serpentine Pulley Kits Facilitate the use of Balmar High Power Alternators

• Better Power Transfer
• Reduced Vibration and Belt Dust
• Quieter Motoring

Single Vee pulleys can only support alternator power loads (PTO) of up to 100A for 12V applications (45A for 24V applications). A serpentine pulley provides greater surface contact between the belt and pulley, and thus can accommodate much higher PTO requirements.

AltMount^® Pulley Kits are designed uniquely for each engine listed below, including all the hardware required to complete the installation. The system is installed by placing and fastening a conversion pulley over the existing crank pulley and replacing the water pump pulley. Two serpentine belts are provided with each kit. 

AltMount^® Pulley Kits are designed to be used with Balmar 6-Series, XT-Series and AT-Series Alternators.  We cannot guarantee fit with other brands of alternators.   For 95-Series Alternators, use the 48-AM-39 alternator pulley. For 7-Series Alternators, use the 48-AM-102 alternator pulley.  For Hitachi Alternators, use the 48-AM-97 alternator pulley.

AltMount^® Pulley Kits install easily and deliver a marked improvement in power transfer while reducing noise and engine vibration.   View the installation video below to see how easy it is to install an AltMount^® Pulley Kit, then select a kit for your engine from list!
