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 cannot tell from where.
Solution
: Must isolate all moving parts.
1. Unplug treadmill.
2. Disconnect drive belt.
3. Turn treadmill on, listen for noise.
• If noise is not present proceed to next step.
• If noise is present, drive motor must be the source.
4. Reconnect the Drive Belt and loosen the Treadbelt completely.
5. Turn treadmill on, listen for noise.
• If noise is not present, Rear Roller must be source (bearings).
• 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.
Note:
The Treadbelt must be loose enough that when the treadmill is powered up the Treadbelt does not move.
6.3.1. Rollers (Drive and Take up)
Rollers only have two moving parts, the bearings located on either end of the roller. The place to check for noise is
on the shaft coming out of the roller because it is close to the bearings and does not move. Many technicians will
hold the blade end of screwdriver onto the shaft and place 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.
When you hear any bearing noise, replace the roller.
6.3.2. Treadbelt, Deck and VFX Noises
• Replace a damaged treadbelt. See “Deck and Treadbelt” on page
• Check that the treadbelt is tensioned properly. See “Treadbelt Tensioning” on page
Decks are solid pieces of wood with a phenolic coating that rest on the VFX cushioning system.
• The deck can make a squeaking noise when the VFX hardware is not properly tightened or lubricated. You can
test for this by bouncing on the deck when the machine is not running.
• Sometimes the deck will need to be lubricated on the sides that go into the frame rails. Use Lubriplate grease
sparingly.
• If a part on the VFX system is broken the deck will make a clunky noise when it bounces against the damaged
part. Check the Impact absorbers,
• A deck may also make a scraping noise when it is worn out.
