Measure your old V-belt, timing belt, or pulleys to find the right belt replacement if you don’t know the trade size.
High-Torque HTD Timing Belts
 |  |
Curved teeth engage with the matching pulley better than standard trapezoidal teeth, so these belts transmit about twice the torque. All are compatible with Gates PowerGrip HTD, Omega HP, and Carlisle RPP series.
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.

High-Torque HTD Timing Belt Pulleys
 | |
Bushing Bore |
Curved teeth engage with the matching belt better than standard trapezoidal teeth, so these pulleys transmit about twice the torque. All are compatible with Gates PowerGrip HTD, Omega HP, and Carlisle RPP series.
Steel—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.
