If you hear a grinding or clicking noise, experience excessive vibration during
exercise, or if the pedals are not functioning properly, you probably have a
problem in the drive train. Attempt to isolate the problem area by performing
the following tests in precisely the order listed below. Refer to the “Parts Re-
moval and Replacement” section for all disassembly and assembly instruc-
tions.
1. Unplug the machine and remove the bottom side covers.
2. Noise can be generated by a Poly-V or HTD belt that is either too tight
or too loose. Check the condition and the tension of the belts. Re-
place worn belts. Adjust the belt tension according to the instructions
in the "Parts Removal and Replacement" section.
3. Remove the Poly-V belt and move the pedal arms. If the noise no
longer exists, check the condition of the alternator. If the noise is still
present, go to step #4.
• Disconnect the DC power cable if you have a 4600/4400/4200 PT
or unplug the connector from position J4 on the power supply
circuit board if you have a 4600/4400 CL. Spin the alternator
pulley with your fingers. It should spin freely and remain spinning
for at least two revolutions. If it does not, the alternator should be
replaced.
• If the alternator does spin freely, check the alternator for noise,
roughness, or the presence of an excessive amount of black
powder inside the alternator or near the outside of the case. If
any of these conditions exist, the brushes might be bad and the
alternator should be replaced.
