The Gates Super HC SPB 1690 is a narrow wedge V-belt for industrial drives. Before you fit a new belt, inspect the drive and sheaves: worn grooves, misalignment, or damaged sheaves will shorten belt life and cause slippage.
Check sheave grooves for wear, rust, or debris. Use a groove gauge to confirm the profile still matches the SPB cross-section. Verify that the sheaves are aligned and that the driven equipment turns freely. Replace worn or damaged sheaves before installing the new belt.
This belt has an SPB profile, a 1690 mm length, a 16.3 mm top width, a 13 mm height, and a 40° angle. When replacing, confirm the part number on the old belt matches SPB 1690. If the old belt is worn or the marking is unreadable, measure the length and check the sheave profile.
For multiple-belt drives, replace all belts in the set at the same time. Mixed worn and new belts can cause uneven tension and vibration. After installation, check tension and re-tension after the first hours of operation.

- No. Replace all belts in the set at the same time to maintain even tension and avoid vibration.
- How do I confirm the belt matches my drive?
- Check that the old belt is marked SPB 1690. If the marking is gone, measure the length and verify the sheave profile is SPB.
