Adjust or Replace Treadmill Walking Belt, Everything You Need to Know

It is important to adjust a treadmill walking belt when it is needed because if you don’t there are likely to be some bad consequences, such as increasing wear and tear on the belt or motor or worse. For example if you start to notice your treadmill belt shifting to one side, then you'll need to switch the treadmill off immediately, otherwise you may end up with a problem like the one you see here • Treadmill: Folded Walk... . We will show you how to make adjustments so that the belt is centered and what are the best practices. We will also show you how to replace the treadmill belt (very detailed step-by-step guide). Your treadmill may be a little different than the one shown here, however the principles are the same.
Also, have you heard of the treadmill "walking belt guide"? No videos we have seen mention 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. Your walking belt guide may be a little different than the one shown here, however the principles are the same. We are sharing this with all of you also so that you both understand its function and so that the walking belt guide will not contribute to unnecessary wear and tear of the belt.

Same model treadmill here purchased new 20 years ago. Replaced walking belt 2 years ago. I use dry paraffin wax for deck lube. (good/bad?) Lately the walking belt hesitates (it is tightened). New drive belt maybe?

[@GusMahn]

Maybe I missed it, but I didn't see or hear you talk about lubricating the walking belt.

My band moved to the left way to much and i cant turn the allen wrench in the holes because its too tigjybhow can i fix it?

[@americarocks1776]

I've monkeyed around with the bolts on the front and the back and have no idea where they belong. I have tried to even them out and I just can't get them all even. What is your recommendation to realign The front and rear tension bolts?

[@GeniusAsian]

it depends on if you are making coarse adjustment or fine-tuning. When you begin don't change all bolts at the same time, otherwise you no longer have a baseline, all parts are moving, it would take longer. If you are making coarse adjustment without a baseline, you can check to see if the rails and the rollers are 90 degree. And then adjust the bolt to see if it shift or the left right. Make sure you write down how many turns on paper, writing down on paper the turns will save you a lot of time or frustration. If over corrected, then reverse.

[@americarocks1776]

@@GeniusAsian thanks. The rear roller ended up requiring very different number of turns where the one side was about a half inch further out to get the belt tight. That was even after I measured and made sure all the parts where the same distance from a reference point on the frame.

[@GeniusAsian]

@@americarocks1776 when you removed the bolt, was it half inch one side further out? and what about the 90 degree angle? If you can find the same brand and model in store or somewhere, may be you could compare

Unrelated question. I have a Lifespan TR800 under desk treadmill. The treadmill motor started to overheat and produce a burning smell after an hour of walking. I replaced the motor and I still have the same problems. What are your next suggestions?

[@GeniusAsian]

how tight is the belt?

[@eniac78]

@@GeniusAsian The walking belt? I think it was too tight. I heard that I ought to be able to lift it to the point I can insert my hand underneath to the middle. So I loosened it. Still, I smell burning after 30 mins.

[@eniac78]

@@GeniusAsian It was rather tight. Hard to get fingers under or lift up. I saw this was bad. Loosened the belt and it's not running hot anymore. I think. Going to do a couple hours and we'll see. Any other suggestions if this doesn't work? Thanks!

[@GeniusAsian]

@@eniac78 if running hot, it means somewhere the friction is too high. The most likely is the belt, but if not then it could be the motor. You said you replaced the motor, I assume you replaced it with a new one, is it the OEM motor? (make sure the motor is not too small). When it starts smell, can you detect from where the smell comes from? (divide the treadmill with a cardboard so that you know if it is front or back etc). If you can pin point the location, then you will find it as the temperature will be high there. This is purely physics friction, try to pull the suspicious spot to see if it is tight or need lubrication.

Has anyone thought of using milimetre measurements instead of drawing lines on a paper?

[@angeloesver1007]

We’re looking for mechanic to replace the belt can you refer a mechanic I live in Modesto California
