NOISES
Many times a treadmill will tell you what’s wrong with it by the noises it makes. We strongly
recommend the use of an automotive stethoscope.
Service Tip: Treadmill making noise but can’t tell from where.
Solution: Must isolate all moving parts.
1) Unplug treadmill.
2) Disconnect Drive Belt.
3) Turn treadmill on, listen for noise.
a)If noise is not present proceed to next step.
b)If noise is present, drive motor must be source.
4) *Reconnect the Drive Belt and loosen the Treadbelt completely.
5) Turn treadmill on, listen for noise.
a)If noise is not present, Rear Roller must be source. (bearings)
b)If noise is present, Drive Roller must be source. (bearings)
6) With Treadmill off, bounce or jog in place on Deck. If noise is present then deck or frame is
making the noise.
* The Treadbelt must be loose enough that when the treadmill is powered up the Treadbelt
does not move.
Rollers (Drive and Take up
)- Rollers only have two moving parts, i.e. the bearings located on
either end of the roller. The place to check for noise is on the shaft coming out of the roller since it
is close to the bearings and doesn’t move. Many technicians will hold the blade end of screwdriver
onto the shaft and their ear next to the handle end to be sure they are identifying the location of the
noise. The most common sound is a clicking that comes from a bearing that is no longer round.
Other noises can be a rumbling (like rolling something around in a metal drum) and in worse cases
a grinding metallic noise.
Treadbelt noises
Questions to ask:
1. Has the belt been broken in correctly? Treadbelts need to be walked on to have wax penetrate
them. Starting at the back walk from side to side and up and down for at least 20-30 minutes to
break in belt.
2. Is treadbelt tracked correctly? If belt is off to one side it may be rubbing, making noise. Track
using bolts on rear roller.
3. Is treadbelt over-tightened? This is the most common cause of groaning type noises. First,
loosen treadbelt and see if noise goes away. If noise goes away, tighten belt only until there is
no slippage when walking.
