Treadmill: Folded Walking Belt Fix, Replace & Adjust

Key Takeaways

• Also, have you heard of this treadmill “walking belt guide”
• No one has talked about this, and it took us significant time and effort to get any information from the manufacturer, but we found it was a very important part for keeping the belt centered
• We are sharing this with all of you also so that the walking belt guide will not cause unnecessary wear and tear of the belt

Understanding the Basics

The walking belt runs on two rollers: the front roller (driven by the motor) and the rear roller (adjustable for tension and alignment)

• Belt tension is controlled by two bolts at the rear of the treadmill — tightening them increases tension and also adjusts left-right alignment

The DIY Advantage

A treadmill repair service call costs $100 to $200 for the visit plus parts. A replacement walking belt costs $30 to $80 online. The adjustment process requires only an Allen wrench and costs nothing.

Tips for Best Results

When adjusting belt tension, make small turns (quarter-turn increments) and write down how many turns you make so you can reverse the adjustment if needed. If the belt needs replacement, photograph the disassembly process so you have a reference for reassembly. When installing a new belt, make sure the walking belt guide is correctly positioned — an incorrectly seated guide causes rapid belt wear. After reassembly, check belt centering at low speed before running at full speed.
