Question about Precor 9.31 Treadmill
I have a Precor 9.3 Treadmill. I"m having problems mounting the console board. When I mount the bolt in the front of the console board, that"s fine, but when I go to mount the 2 bolts in the back , they won"t reach to mount.The only way for them to reach is to lay the console down a bit,but then the console board is down more rather than sitting up. Has anyone had this problem.

This probably did not happened suddenly right? the problem is not the motor however you can easily check the blue capacitor for peace of mind. with the power disconnected, disconnect one side off the capacitor from the top. with a ohm meter put the 2 probes on the cap,you will ear a temporary beep sound from your meter, then reverse your probes on the capacitor and again a temporary sound that mean your capacitor is good and your motor will run OK.
Your problem is more then likely your run belt and bed assembly. When new, these are coated with a wax of some kind for slipping, has you use the machine wax wears off, and so is the belt. You can see a black rubber dust at the rear of the machine. And so resistance increase when pressure is applied on the running belt.
Just behind the on/off switch where the power cord goes in, there is a auto reset 15 amp breaker that trips when too must resistance against the motor increase the amperage over 15amps. At 7 min/m on your speed setting and if the belt is adjusted correctly with nobody on, the motor pull about 6amps, with someone like me 180lbs, the motor pulls an avg of 10amps with a new belt.
If you have a clamp amp meter you can test it yourself.
2 parts you will need to fix this; 50985-101 (bed assembly) and 36355-101 (run belt 17 X 110) This is real easy to install.
make sure these parts are for your machine model # as they did increased the width of their belt over the years
Since 1998 I had to replace these parts 2 times with an average of 3 people using the treadmill every day. This is a good machine and if everything else is good it's worth it. I paid $300 for these parts, i'm sure if you shoppe a little you can do better.
Have a good one

Static Shock Problems:
Many people face a conundrum when using a treadmill. The problem is that a treadmill has you walk or run in a motion that causes you to build up an electrical charge on your body while you are exercising.
The problem if you are swinging your arms, you are totally isolated from any common ground so the charge just builds and builds and many discharges have been measured above 30,000 volts.
You may say, how in a frost-covered hell can I build up 30,000 volts on my body without killing myself? Good question and it has a good
answer...there is very little amperage. It will pop you good when you do ground and sting but it won't hurt you.
The problem is that it can damage the treadmill's electronics if it is not properly designed and we still see poor designs in this respect
If you don't like getting popped or if your treadmill is shutting down or going crazy, there is a fix. You can ground yourself to keep the electricity from building up on your body.
We now have wrist grounding straps that can be reused and attach to the frame of the treadmill without causing any markings and do not require any permanent modification to your treadmill. You can find them in any online catalog by electronic sales by searching for Grounding Strap.
Thank in advance, sincerely. God bless you.

Do you know which version of the Precor 9.21 you have? There are a few different versions you can view here. Click on your version to view the parts list and look for "Cover, Motor" or "Motor Cover".
For instance, if you have the 9.21 (AYYZ), the proper motor cover is this part #5019749
However, this part #5005569 is listed as the proper motor cover for the 9.21 (F5), 9.21i (2X), 9.21s (F6), 9.21si (2Y), and a couple others. Make sure you have matched up your exact model number with the motor cover you need so do you not order the wrong part.

Drive Belt Installation for Treadmills
The drive belt is used by the motor to drive the
treadmill walking belt via the front roller pulley. A drive pulley is mounted
on the roller and the roller has knurling or a sleeve to help it drive the
walking belt. The treadmill console detects the current speed of the treadmill
by monitoring the movement of a magnet mounted on the front roller pulley with
a reed switch or by using an optic switch which monitors an optic disk mounted
either on the front roller or on the motor shaft. If the sleeve moves to the side, you will not
be able to keep the belt centered and many optic disks can be warped if pushed
to the side by the sleeve if it moves, but we do have replacement sleeve kits
Steps to Replace
1) Remove the safety key and unplug the treadmill
from the wall outlet.
2) Remove the screws securing the motor hood and
gently remove the motor hood.
3) Using an Allen wrench provided with the
treadmill, loosen the two rear roller adjustment bolts until the rear roller
comes into contact with the walking board.
Turn the bolts and equal number of turns on each side and keep a count
of how many turns you made so you will know how to properly re-tension the
4) Remove the drive belt from the motor pulley.
Place a screwdriver between the pulley and the belt and turn the pulley by
hand. Use the screwdriver to guide the belt over the edge of the pulley. Be careful with the screwdriver to prevent
damage to the pulley.
6) Mark the position of the front roller axle on the
front roller bracket above the front roller adjustment bolt using a Sharpie
marker so you will know where to put the bolt back into position. Remove the
front roller adjustment bolt if your treadmill's front roller has a pitch adjustment
bolt. If your treadmill does not have
exposed roller bolts you will need additional instructions. Please see the troubleshooting section on our
website for further help.
7) Gently slide the front roller from out of its
mounting position on the frame. Do NOT
remove the roller from the walking belt.
8) Slip the old drive belt off the roller and loop
the new drive belt onto the front roller pulley.
9) Replace the roller back into its slot on the
pulley side and re-tension the front roller pitch bolt to its proper place
using the Sharpie mark as a guide.
10) Using the screwdriver, loop the drive belt over
the motor pulley. Many Icon units
originally had the drive belt misaligned by design (if you can believe
it). This was to use the side load of the
drive belt in order to keep tension lower.
It does lower amp draw for the machine and replacing a side load drive
belt occasionally is much cheaper than replacing a motor and/or controller so
if your original drive belt was off-centered, install the new belt in the same
11) Re-tension the walking belt.
12) Plug in the machine and check the drive belt for
slipping. You can use some automotive
fan belt dressing on the grooved or contact side of the belt to help it with
grip on the pulleys and it will treat the belt as well. We prefer using belt dressing rather than
over-tensioning the belt for the aforementioned amp reasons as well as
additional stress placed on the drive system parts.
13) Replace the motor cover and test.
Make sure the walking belt is not slipping and is properly aligned and your
treadmill is ready to use.
