The Gates 7440 Automotive XL High Capacity V-Belt is a heavy-duty accessory drive belt designed for compatible V-belt pulley systems. Its notched/cogged construction helps improve flexibility around smaller pulleys, reduce heat buildup, and support reliable power transfer in demanding accessory-drive applications.
This belt should be selected by exact belt number, cross-section, top width, outside circumference, effective length, pulley profile, and required application chart.

Application Compatibility
Common application context includes V-belt accessory drive systems where the required replacement belt matches the 7440 size and profile, including:
- Automotive accessory-drive systems where specified.
- Equipment and machinery using a 7/16 in. top-width V-belt profile.
- Alternator, water pump, fan, and power-steering belt positions where the belt chart calls for 7440.
- Marine or industrial crossover applications only where the belt length, profile, pulley width, and service chart confirm this belt.
Use this belt only where the application catalog or measured belt specification confirms Gates 7440 or a verified equivalent.
Fitment Notice
Confirm fitment by application chart, pulley groove profile, top width, effective length, outside circumference, belt routing, and tension adjustment range before ordering. Belt numbers can appear similar while differing in length, width, profile, or construction. A belt that is too short, too long, or the wrong cross-section can slip, squeal, overheat, wear pulleys, or overload accessory bearings.
When This Product Needs Replacement
Replace the belt if it is cracked, glazed, oil-soaked, frayed, stretched, hardened, noisy, slipping, missing cogs, or riding too low in the pulley groove. Replacement is also recommended during accessory replacement, seasonal service, overheating diagnosis, alternator charging complaints, or whenever belt tension can no longer be set correctly.
Installation Notes
Inspect all pulleys before installation. Pulley grooves should be clean, aligned, and free of rust, burrs, oil, and belt debris. Install the belt without prying against pulley edges, then tension according to the equipment manufacturer's specification. Recheck belt tension after initial run-in where required.
Do not use belt dressing to correct slippage. Slippage should be corrected by verifying belt size, pulley condition, alignment, and proper tension.

Parts Desk Insight
For V-belts, the most important checks are top width, effective length, pulley groove match, and adjustment range. A belt may look close by length but still ride incorrectly in the pulley if the profile is wrong. For best service life, replace worn belts with clean pulleys, correct alignment, and proper tension rather than relying on belt dressing or over-tightening.
