Measure your old V-belt, timing belt, or pulleys to find the right belt replacement if you don’t know the trade size.
Timing Belts
 |
 |
Keep your drive system in sync. Trapezoidal teeth mesh with matching pulleys to transmit power without slipping. With the original tooth profile, these timing belts handle enough torque and synchronization for most applications. If you need high torque or precise starts and stops, consider curved tooth profiles, such as GT and HTD belts.
Neoprene—Durable and weather resistant, but lose elasticity if exposed to oil and fuel. These belts are reinforced, so they're strong enough to transmit power without stretching. Plus, nylon-coated teeth minimize friction and protect the surface from wear.

Timing Belt Pulleys

Bushing Bore |
|
Keep your drive system in sync. Trapezoidal teeth mesh with matching belts to synchronize motion. With the original tooth profile, these pulleys handle enough torque for most applications. If you need high torque or precise starts and stops, consider curved tooth profiles, such as GT and HTD pulleys.
Iron—Strong but best for dry environments since moisture will cause them to rust.
Bushing Bore—Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Mount a bushing (sold separately) on your shaft and slide the pulley over it. As you tighten the included set screws, the bushing grips the shaft and draws it into the pulley, creating a final hold that is more secure than with set screws alone.
