- Match the HTD tooth spacing to stay locked with your actual strap pitch
- Pick a model packed with a fully enclosed runner to shed dust and grit fast
- Dial in exactly 7 percent belt deflection to balance load capacity and bearing life
- Swap out tired tensioners before heat buildup wears out your motor shaft
