Balmar XT-CR-170-K6 High-Output Marine Alternator 170A 12V K6 Serpentine Pulley

The Balmar XT-CR-170-K6 is a high-performance 170-amp, 12-volt marine alternator specifically engineered for Yanmar Common Rail engines introduced after 2013. Part of Balmar's advanced XT-Series, this alternator features a state-of-the-art braided stator wire design that delivers exceptional charging power in a compact, marine-friendly package.

Key Features:

• 170A maximum output with up to 128A at idle speeds for superior low-RPM performance
• 3.15-inch Hitachi-style dual foot saddle mount configuration
• K6 six-groove serpentine pulley pre-installed
• Case ground design for reliable electrical connections
• Smart Ready® internal voltage regulator with optional external regulation capability
• Dual fan cooling with high airflow frame for optimal temperature management
• Operates 9°-18°F cooler than previous AT-Series designs
• USCG Title 33, CE, ISO 8846, and SAE J1171 certified

Technical Specifications:

• Output: 170 amps at 12 volts
• Mounting: 3.15-inch dual foot saddle mount (Hitachi-style)
• Pulley: K6 serpentine (6-groove)
• Ground: Case ground
• Weight: Approximately 14 lbs

Application:

This alternator is specifically configured for Yanmar Common Rail diesel engines and is also compatible with Westerbeke, Lehman, and Perkins-Sabre marine engines using Hitachi-style mounting. It replaces older Balmar models AT-DF-165-12-IG and AT-DF-165-K6.

Important Notes:

• Must be used with dual vee or multi-groove serpentine belt configurations
• May require Tachometer Signal Stabilizer (Part No. 15-TSS) if existing tachometer is not adjustable
• Ideal for large battery banks including lithium battery systems
• Provides additional fault tolerance for cruising applications

The XT-CR-170-K6 delivers reliable, high-output charging performance for demanding marine electrical systems, making it ideal for vessels with significant house loads, multiple battery banks, or extended cruising requirements.
