HVAC & Equipment V-Belt C148, Replaces Dayco C148GL, Timken CP148

The C148 V-belt transfers power in compatible classical C-section sheaves. Match the complete original belt marking and the equipment manufacturer's length system before ordering.

Cross-Reference Information

Length-system warning: Inside, datum and outside lengths are different measurements. Manufacturer tables can show different numeric lengths for the same C designation. Match the exact belt number and measurement system rather than comparing one loose-belt measurement.

Cogged Performance Alternative

No CX crossover was added because this size was not published in the official CX size table used for this audit.
