C300 Industrial V-Belt — Dayco C300GL, Timken CP300

The C300 V-belt transfers power in compatible classical C-section sheaves. Match the complete marking and the equipment manufacturer's length system before ordering.

Cross-Reference Information

Length-system warning: Inside, datum and outside lengths are different measurements. Do not compare one loose-belt measurement with a manufacturer table that uses another length system.

Common Symptoms

• Belt slips, squeals or overheats under load
• Driven equipment runs slowly or inconsistently
• Black belt dust appears around the sheaves
• Belt is cracked, glazed, stretched or frayed

Check Before Replacing

• Confirm the C-section profile and complete original marking
• Identify whether the specification uses inside, datum or outside length
• Inspect the sheaves for wear, rust and groove damage
• Check shaft alignment, bearings and required tension

Installation Notes

1. Disconnect and lock out electrical power.
2. Relieve belt tension according to the service manual.
3. Inspect and clean the sheaves.
4. Install without prying, align the drive and set tension to specification.
5. Rotate by hand, reinstall guards and test operation.
