The B-section designation identifies this as a standard B-profile industrial V-belt — 21\/32 inch top width, 13\/32 inch depth. The 36 designation indicates the belt pitch length in inches. This belt drives the compressor pump from the motor pulley and is a normal wear item that requires replacement on a maintenance schedule or when wear signs appear.\u003c\/p\u003e\u003cp\u003eCast Air's industrial compressor lineup uses B-section V-belts throughout the C1, C2, C3, and C4 pump families. The specific belt length varies by pump size, HP rating, and pulley configuration. Ordering the correct length belt for your specific compressor model is critical — an undersized belt will not reach the pulleys, and an oversized belt will not maintain proper tension.\u003c\/p\u003e\u003ch2\u003eBelt Identification\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSection:\u003c\/strong\u003e B (21\/32\" top width x 13\/32\" depth)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Length:\u003c\/strong\u003e 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Standard industrial V-belt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Air compressor drive — motor pulley to pump flywheel\/sheave\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhen to Replace the Belt\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCracking or checking visible along the sidewalls or underside\u003c\/li\u003e\n\u003cli\u003eGlazed (shiny) belt surface — indicates slippage, reduces drive efficiency\u003c\/li\u003e\n\u003cli\u003eBelt has stretched beyond the motor mount adjustment range\u003c\/li\u003e\n\u003cli\u003eSquealing at startup or under load\u003c\/li\u003e\n\u003cli\u003eVisible fraying, chunking, or material separation\u003c\/li\u003e\n\u003cli\u003eRoutine replacement at the manufacturer's recommended interval (check your compressor manual for hour-based interval)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eDepressurize the compressor and lock out the electrical disconnect before replacing the belt. Slide the motor mount to release tension, remove the old belt, route the new belt over both pulleys, and set tension so the belt deflects approximately 1\/2 inch under moderate finger pressure at the center of the span. Tighten the motor mount fasteners and recheck tension after the first operating session — new belts seat slightly during break-in and may need a minor tension adjustment.\u003c\/p\u003e\u003cp\u003eIf your compressor uses matched belt pairs (some C3 and C4 configurations), replace both belts simultaneously. Mixing a new belt with an old stretched one causes uneven load sharing and accelerates wear on both.\u003c\/p\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eB36 length fits a range of mid-size compressor drive configurations in the Cast Air lineup.
