HVAC & Equipment V-Belt B236, Classical B-Section Drive Belt

The B236 V-belt transfers motor power to a compatible driven sheave. The B number is the primary classical belt designation. Match the original marking, section and manufacturer specifications before ordering.

Cross-Reference Information

Important: Manufacturer-published outside lengths can vary because the B designation is based on an industry classical length system and accurate belt measurement requires prescribed pulleys and tension. Match the complete part number rather than measuring a loose belt by hand.

Is This the Right Belt?

Common Symptoms

• Belt slips or squeals under load
• Fan, blower, pump or conveyor runs slowly
• Black belt dust appears around the sheaves
• Belt is glazed, cracked, stretched or frayed

Check Before Replacing

• Confirm the B-section profile and full original belt marking
• Inspect sheaves for worn, polished, rusted or dished grooves
• Check shaft alignment and bearing condition
• Confirm the required service rating and tension specification

Installation Notes

1. Disconnect and lock out electrical power.
2. Relieve drive tension according to the equipment service manual.
3. Do not pry the belt over a pulley; create enough slack for installation.
4. Align the pulleys and set tension to the equipment manufacturer's specification.
5. Rotate the drive by hand, reinstall guards, restore power and test operation.
