How to Measure a Belt

Accurately measuring your belt is crucial for proper replacement. You will need a standard tape measure or a specialized belt measuring tool. The video below demonstrates the process.

Measuring Belt Width

To measure the width, place a standard tape measure across the top side of the belt. For accuracy, it is recommended to start measuring from the 1-inch mark on your tape measure. This belt is 1/2 inch wide.

Understanding Belt Types and Applications

Different belt types are designed for specific applications to ensure optimal performance and longevity. Using the correct belt type is crucial for your equipment's efficiency and safety. The video below provides an overview of common belt types.

Video: An overview of various Stens OEM replacement belt types, including covered, raw edge, cogged, and double V belts, and their typical applications.

Covered Belts (e.g., Stens 265-703)

• Characteristic: Fully covered with fabric, preventing exposed cords.
• Application: Often used in deck belt situations where some slippage is desired to prevent damage to the mower or operator if an obstruction is hit.

Raw Edge Belts

• Characteristic: Exposed cords on the edges, no fabric wrap.
• Application: Designed for applications requiring no slip, such as power trains in self-propelled mowers, especially on inclines or wet ground, to ensure consistent power delivery to the wheels.

Cogged Belts

• Characteristic: Features cogs or teeth on the underside, exposed cords, and no fabric wrap.
• Application: Similar to raw edge belts, providing maximum grip and no slip. Commonly found in zero-turn mower hydro belts and other power train applications where enhanced traction against pulleys is needed.

Double V Belts

• Characteristic: Features a V-shape on both sides, allowing for bearing surfaces on either side of the belt. Can be raw edge or covered.
• Application: Used in systems where the belt needs to twist and turn, engaging pulleys from both its top and bottom surfaces, such as certain large deck belts.

Maintenance

When to Replace Your Belt

The OEM owner's manual for your equipment typically provides a timetable for belt replacement. However, visual inspection can also indicate when a belt needs to be replaced. Look for the following signs:

• Fraying: Visible loose fibers or threads on the belt's surface or edges.
• Dry Rot: Cracks, stiffness, or a brittle appearance, often due to prolonged storage or exposure to elements.
• Cuts or Tears: Any physical damage to the belt material.
• Excessive Wear: Noticeable thinning or glazing of the belt's surface.
• Performance Issues: If the belt is slipping, making unusual noises, or failing to transmit power effectively.

If any of these conditions are observed, it is the perfect time to replace your belt to ensure optimal performance and prevent further damage to your equipment.

Troubleshooting

Common Issues and Solutions

• Belt Slippage: If your equipment's belt is slipping, especially under load or in wet conditions, it may indicate that an incorrect belt type (e.g., a covered belt in an application requiring a raw edge or cogged belt) is being used, or the belt is worn out. Ensure you are using the correct belt type as specified by the OEM.
• Premature Wear: Rapid wear of the belt can be caused by misaligned pulleys, improper tension, or foreign objects interfering with the belt's path. Inspect pulleys for damage or misalignment and ensure proper belt tension.
• Belt Noise: Squealing or chirping noises can indicate a loose belt, worn pulleys, or contamination (oil, grease) on the belt or pulleys. Check tension, inspect pulleys, and clean the belt and pulley surfaces.
