It can measure a deflection force up to 30 lb., ensuring that the proper amount of belt tension is applied for increased life of the drive belt. This single-barrel tension tester is suitable for maintaining power transmission systems in a range of industrial settings.Gates manufactures power transmission and fluid transfer components and systems. The company, founded in 1917, is headquartered in Denver, CO. Review: Easy to use and recommended by manufacturers. - Very easy to use! I work on aircraft with ac belts and some times it gets a little annoying trying to use other methods to measure belt tension. This tool works great, a must have for mechanics of all kinds. Also it was recommended by the ac manufacturer. Review: Great tension tester and easy to use - I have an '04 Hyundai Elantra and I had replaced all my drive belts (3 total) and tensioner pulley on the air conditioning belt due to a squealing sound. The work was a bit of a pain to do, but the manual mentioned that I needed to tighten the belts to various tension measurements with 22lbs of force. I thought, I can guess what that is and tightened the belts till they felt tight. 2 days later it was cold and my belts started squealing again. I did a little research to find what kind of tool would let me know if I tensioned my belts correctly and came across this device. I use gates parts and belts and have had good success, so I figured I'd give this guy a try. It is very easy to use, you push down on the center of the belt with the plastic part of this tension tester in the palm of your hand. I used a straight edge across the belt and pushed the rubber gasket (on the thicker part of the tensioner) up between 8-11 mm or 12-15mm(depending on what each belt called for) and pushed down on the tensioner till that gasket was level with my straight edge. Then I looked at the small gasket to see how many pounds of pressure I had exerted. If It was say 15 lbs and I needed to get to 22, I would tighten the belt and try again. And I'd do the reverse if it was a higher reading. At any rate, using this device I found that I had significantly under-tightened all of my drive belts. Since using this, I'm confident they are at the correct tension and I no longer have any squeals. ## Features - Single-barrel tension tester for use with small V-belts and synchronous belts - Maximum deflection force of 30 lb. - Ensures proper belt tension for increased life of drive belt - Country Of Origin: United States ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00CJEGXK6 | | Brand | Gates | | Brand Name | Gates | | Color | Black | | Compatible Devices | Vehicles and industrial machinery with small V-belts and synchronous belts | | Customer Reviews | 4.4 out of 5 stars 382 Reviews | | Global Trade Identification Number | 00072053109955 | | Item Dimensions | 8 x 8 x 11 inches | | Item Weight | 0.01 Ounces | | Item dimensions L x W x H | 8 x 8 x 11 inches | | Manufacturer | Gates | | Measurement Type | Pounds" or "Pound-force | | Model | 7401-0076 | | Part Number | 7401-0076 | | Power Source | Corded Electric | | UPC | 072053109955 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Gates - **Color:** Black - **Item Weight:** 0.01 Ounces - **Item dimensions L x W x H:** 8 x 8 x 11 inches - **Power Source:** Corded Electric ## Images ![Gates 7401-0076 Pencil Type Tension Tester, 30 lbs Deflection Force - Image 1](https://m.media-amazon.com/images/I/61NX7s7jW6L.jpg) ## Questions & Answers **Q: Sir, do you have the tension gauge in 30-35lbs. deflection force capacity?** A: max is 35lb which is some capacity, wouldn't want to speculate on accuracy ! **Q: Where do I find deflection force?** A: At the customary mid-point deflection of 1/64" per inch of span, the deflection force is about 1/16 the actual belt tension. Deflection force is read off the telescoping stem of the tension gauge, but be sure to slide the O-ring all the way back before using the tool. Use the inch scale on the barrel of the tool along with a straight edge to measure the deflection. (Note: the barrel goes against the belt; you push on the telescoping stem.) You can find the recommended belt tension in manufacturers tables. **Q: what is the tool diameter ?** A: Hello, The diameter of the tip that pushes on the belt is 0.8 cm and the ticker part above is like 1.1 1.2 cm **Q: What is the size (Length) of this gauge?** A: About the length of a wood pencil after a couple of sharpenings. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use and recommended by manufacturers. *by A***R on July 24, 2025* Very easy to use!

For the 25 lb measurement I found the force scale to be within 10% accuracy, which is suitable. ## Frequently Bought Together - Gates 7401-0076 Pencil Type Tension Tester, 30 lbs Deflection Force - Gates 91107 Krikit V-Belt Tension Gauge, Black - Gates 91132 Krikit V-Ribbed Belt Tension Gauge , Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/4381367-gates-7401-0076-pencil-type-tension-tester-30-lbs-deflection](https://www.desertcart.tn/products/4381367-gates-7401-0076-pencil-type-tension-tester-30-lbs-deflection) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-08*
