Need replacement roller bearings for cardiozone treadmill model CZSG55

the only lubrication that needs done is between the walking belt and the deck. if a roller is squeaking either front or rear you can try using wd40 on the bearings on either side

Hello.
Knocking noises more than likely come from the rear roller, there could be a small chance it's coming from the motor it's self though.
Have some walk on the machine and make the noise while you locate which end of the treadmills coming from.

If it is the rear roller the bearings will need to be replaced, this can be done by removing the rear roller and taking it down to any bearing shop and have them locate the bearing numbers. Ask them for advise on removing them as well.

If the noise is coming from the front of the treadmill then have a look at the fly wheel coming off the motor, locate grub screws and tighten.

If the console takesbatteries, replace them. If this does not work or your console does not requirebatteries, check the reed switch or optic sensor. Reed Switch:Unplug the treadmill and remove the motor hood cover. The reed switch is mountedon the frame next to the front roller pulley. There is a magnet glued into thefront roller pulley. When adjusting the reed switch, make sure it is pointingdirectly at the magnet. Move the tip of the reed switch within 1/8" of themagnet. Also, check to see that the wire is not damaged, and is connected tothe console. 2nd Step: tight the keypanel vs Display board and clean with contact cleaner spray . Tight the connector from Display Board vs Main Motor Board.

See the block diagram how the main motor board has aprox 90% functions in any treadmill. Good luck, Now you will strong resultant in determine what is faulty.

1st take side rails off front hood .you have afront roller and a back roller. for the front take out the two or one bolts holding the the roller in placenow the back roller take out the bolts that hold the roller in place . now on the deck there is 3or 4 screwson each side holding the deck in place. slide w/ belt off put on new deck.install screws, rollers ,bolts.. now center w/belt and adjust tention on w/belt

Go to treadmilldoctor.com or call them@ 1-800-750-4766 since Keys Fitness went out of business they bought the parts inventory I am assuming that they will have manual for you unit.

Pretty much the bearings have flatten if you are getting a clunking sound these are normally sealed bearings and it is better to replace the roller. Call Icon Fitness @ 1-800-999-3756
