Cogged Equipment V-Belt AX74, Replaces Dayco AX74GL

AX74 is a raw-edge cogged classical V-belt for industrial and HVAC power-transmission drives. Dayco defines AX as a 13 mm × 8 mm raw-edge profile and uses the number as the inside-length designation.

Verified cross-reference guide

• Exact raw-edge cogged references: AX74; Dayco AX74GL; Gates AX74.
• Wrapped classical alternative: A74. Similar profile and nominal inside-length designation, but not identical construction.
• Dimensional FHP alternative: 4L760. Dayco’s published conversion method connects AX74 to a 76-inch outside-circumference 4L designation; this is not identical construction.

Buyer checks

Match AX74, the AX-section profile, approximately 1/2-inch top width, pulley groove and the supplying manufacturer’s stated length convention. Do not select only from a loose-belt measurement.

Common symptoms

Cracking, glazing, frayed edges, missing cogs, slipping, squealing, heat damage or repeated loss of tension can indicate replacement is due after the pulleys and tensioning system are inspected.

Installation guidance

1. Disconnect and lock out power.
2. Inspect pulley wear, alignment and contamination.
3. Release tension; never force the belt over a sheave.
4. Set tension to the equipment or belt manufacturer’s specification.
5. Rotate by hand, replace guards and recheck after run-in.

Equipment fitment

No reliable model-level equipment fitment was found. Match the exact designation, profile and supplying manufacturer’s length specification.
