1994 Mack FDM V-Belts

Designed for problem, heavy-duty, heavily vibrating applications requiring belt sets. Tie-band feature joining belts together ensures stability lacking in ordinary belt sets.

Product Features:

• Unique tensile cord design gives belt extra strength, added flexibility and shock-load resistance
• Molded notches reduce bending stresses, especially on small-diameter pulleys, while dissipating heat.
• The uniform distribution of the load between the strands allows for better shock absorption.
• Eliminates belt rotation or belts jumping out of the drive
• Meets or exceeds SAE J636 specifications
• Meets RMA oil and heat resistant standards and static conductivity requirements

Designed for the toughest applications, FleetRunner construction provides superior flexibility, stability, load capacity, and unsurpassed belt life. Patented materials deliver peak performance at extreme prolonged operating temperatures making this belt the ultimate problem solver. An advanced blend of EPDM rubber technology withstands the modern threats of deterioration from increased exposure to ozone and water-based coolants. FleetRunner does this all while providing the lowest cost per mile for fleets, including 3/4 and 1 ton pickups.

Product Features:

• The patented material provides optimal performance at extremely high operating temperatures.
• Construction that resists cracking, wear, oil and heat
• The special compound provides unprecedented flexibility, stability, load-bearing capacity and belt life.
• Unique undercord notch pattern offers increased flexibility for smaller diameter pulleys
• Problem solver for troubled drives
• Designed to save your fleet’s money and reduce downtime
• Meets RMA oil and heat resistant standards and static conductivity requirements

Replacement belt for the most demanding engine drives. Due to thermal forces, this variable notched belt actually tightens on the drive as it gets hot. This results in improved belt performance by reducing tension decay and noise.

Product Features:

• The fiber-filled rubber adds flexibility along the entire length of the belt and provides greater lateral stability in the pulley.
• Form-ground to ensure precise top width and sidewall dimensional control for proper fit to the pulley
• Thermoactivated pull cords for maintenance-free performance when properly installed and tensioned
• Resists oil, heat, ozone, weather and aging for improved belt life
• Meets or exceeds SAE J636C specifications

Dayco’s high performance HD V-belt is one of the most innovative, top performing belts for its application. By combining raw-edge construction with a specially formulated polyester cord treatment, it offers excellent resistance to repeated flexing and protection against heat, oil and grease as well as the strength, stability and reliability required for vehicles that still need a heavy-duty V-belt.

Product Features:

• Designed for efficient power transmission to vehicle accessories in today’s trucks and buses
• Provides greater durability and flexibility – 35% stronger than all previous versions
• Features specially treated cords for added strength, stability and reliability
• Made with specially formulated rubber compounds, this belt is highly resistant to extreme under hood temperatures that can cause premature damage to under engineered rubber compounds
