Gates Krikit V-Belt Tension Gauge 91107 — Black, Die-Cast Aluminum, Dual-Scale (lb/kg) for V-Belts up to 7/8"

The Gates 91107 Krikit V-Belt Tension Gauge is a compact, easy-to-use tool that quickly measures V-belt tension to help maximize belt life and drive performance.

Designed for technicians, mechanics, and DIYers, this pocketable tension gauge gives fast, repeatable readings on automotive V-belts up to 7/8-inch top width. Built from die-cast aluminum with a nylon indicator arm and pressure pad, the instrument combines durability with light weight. The readable dual-scale displays pounds and kilograms and covers a practical working range for most accessory belt systems.

How do I use the Gates Krikit gauge for a reliable tension check?

Using the gauge takes only a few seconds: rest the pressure pad against the belt, apply the indicator arm until it contacts, and read the deflection on the scale. Aim for the tension value specified by the vehicle or belt manufacturer. Repeat measurements at a few belt positions for consistency, and adjust the belt before final testing.

• Place pressure pad on belt and swing indicator arm until contact
• Read tension on dual-scale in pounds or kilograms
• Suitable for V-belts up to 7/8 in. top width
• Take multiple readings along the belt span for accuracy

What tension range and scales does this Krikit model support?

The 91107 covers a broad working range useful for most automotive accessory belts. The printed scale displays both lb and kg so you can follow manufacturer specs without conversion. This model measures lower to mid-range tensions commonly found on blower, alternator, and power-steering belts.

• Measurement range: 30 to 160 pounds (15 to 75 kilograms)
• Dual-scale printing eliminates on-the-fly conversions
• Accuracy sufficient for routine belt maintenance checks

Is the Krikit 91107 durable enough for shop use and easy to carry?

The gauge combines a sturdy die-cast aluminum frame with a nylon indicator arm and pressure pad to withstand regular handling without adding unnecessary weight. A stainless-steel pocket clip keeps it handy between jobs, and its compact footprint fits into most tool pockets or bags.

• Die-cast aluminum body for lightweight durability
• Nylon indicator arm and pressure pad resist wear
• Stainless-steel pocket clip for secure, convenient storage

Can I use this gauge on timing belts or other belt types?

The 91107 is engineered for V-belt tensioning only and should not be used on timing belts or synchronous drive belts. Timing belt systems require specific procedures and different tools to avoid harm to engine components. For accurate results, restrict use to automotive V-belts within the specified width and tension range.

• Intended for automotive V-belts only — not for timing belts
• Fits belts up to and including 7/8 in. top width
• Use correct tool and procedure for timing/synchronous belts

Who is this for: The Gates 91107 Krikit V-Belt Tension Gauge is ideal for vehicle mechanics, fleet maintenance teams, and home enthusiasts who perform routine belt inspections and adjustments. If you need a fast, repeatable method to confirm accessory-belt tension and want a rugged, pocket-ready instrument that reads in pounds and kilograms, this gauge is designed to meet those needs. Avoid using it on timing systems and follow manufacturer tension specs for best results.
