What this motor is ideal for
- Legacy HVAC equipment such as furnaces and air handlers that originally used a Century C-Face, 2 HP motor
- Beltdriven blowers and fans in older residential or commercial systems
- Repair projects where a direct C-face, single-speed motor is required to match existing mounting and drive geometry
Why choose this model for your repair or retrofit
When you’re maintaining or restoring aging equipment, compatibility matters as much as horsepower. The B835’s C-Face mounting pattern and keyed shaft make it a reliable match for many legacy systems, allowing you to swap in a motor that preserves original alignment, pulleys, and drive belts without major modifications. Its dual-voltage capability gives you flexibility in wiring configurations, which is helpful when you’re working with older circuits or varying power sources.
Practical considerations for replacement
- Verify mounting and shaft geometry: Ensure the C-Face bolt pattern and shaft diameter match your current setup to avoid misalignment or clearance issues.
- Check electrical compatibility: Confirm your service polarity and wiring method align with 115V or 230V operation, and that any required capacitors or starting components match your system’s needs.
- Cross-reference compatibility: Use the provided cross-Reference numbers (319198 and 663001194552) to locate compatible stock if this exact part is unavailable, since it’s discontinued by Century.
- Plan for installation: Being a direct-drive, single-speed motor, you’ll want to ensure pulley alignment and belt tension are correct to maintain efficient operation and reduce wear.
What you gain with this motor
Reliable, straightforward power for legacy equipment without the need for complex controls. Its keyed shaft and C-Face design simplify retrofits, helping technicians keep older systems running smoothly while preserving original drive geometry. If your unit was built around a Century B835, this motor offers a familiar, compatible solution—even as production has wound down.
