Value Collection 12L0756FSFB3/8 Timing Belt Pulley 12T

Product Description

The VALUE COLLECTION 12L0756FSFB3/8 is a 12-tooth timing belt pulley designed for use with L-series synchronous belts in power transmission assemblies. The pulley features a 3/8-inch bore and a 1.402-inch outside diameter, with a pitch diameter of 1.432 inches. Constructed from steel cast iron, it delivers the rigidity needed to maintain precise belt indexing under load. Licensed HVAC technicians, mechanical contractors, and industrial maintenance trades install this type of component in belt-driven blower assemblies, conveyor drives, and similar timing-critical applications where slippage cannot be tolerated.

This pulley is suited for light-to-medium duty timing drive systems using L-series (3/8-inch pitch) synchronous belts. The 3/4-inch belt width capacity makes it compatible with standard L-series belt widths found in OEM and aftermarket drive configurations. It is a single-piece, fixed-bore pulley appropriate for new builds and drop-in replacements in equipment where the shaft diameter matches the 3/8-inch bore specification.

Key Features

• 12-tooth profile sized for L-series (3/8-inch pitch) timing belts
• 3/8-inch inside bore for direct shaft mounting without additional machining on matching shafts
• 1.402-inch outside diameter with 1.432-inch pitch diameter for accurate belt engagement
• Accepts belts up to 3/4-inch wide
• Steel cast iron construction resists wear and maintains dimensional stability under continuous cycling

Compatibility

Designed as an OEM-style replacement or new-install component for L-series synchronous timing belt drive systems requiring a 12-tooth, 3/8-inch bore pulley with a 3/4-inch belt width capacity.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with belt-drive systems. Disconnect and lock out all power to the drive assembly before removing or installing any pulley. Verify shaft diameter matches the 3/8-inch bore before pressing or securing the pulley, and ensure proper belt tension and alignment after installation to prevent premature belt wear or pulley damage.
