Question about Precor Exercise & Fitness

Open Question

I have a Precor EFX 5.21i. The bolt connecting the running rail (silver) to the chassis structure at the bottom has been loose. Tried to tighten, but still loose after 5 min of use. How to fix this?

Model: Precor EFX 5.21i Problem: Bolt that connects Running rail to the chassis is loose, making the running rail loose and wobble while using the machine. Bought new bolts and washer and tightened it, but still becomes loose after 10 minutes of use.

There is a cover that runs up and down the door. This cover is removed simply by using a thin screw driver and peeling it off. You will find the Bolts under this cover. BE CAREFUL not to over tighten the bolts..

Good Luck

Testimonial: "Thanks for your answer. 159ft-lbs seems a bit high. I only say this because 1990 Honda Integra 1.8L is 130ft-lbs. Maybe because of bigger engine."

SOURCE: bolt comes loose and rip cord is yanked from hand

  1. block off the blade and driver assembly with a 2x4 to keep it from moving
  2. remove the flywheel nut (regular hand force should be sufficient)
  3. tap the 3 holes on the flywheel (if they aren't already threaded) using 1/4inch 20national tap set
  4. remove the flywheel using a flywheel puller -- a harmonic balancer puller which matches the tecumseh bolt pattern on the flywheel also works using 3 1/4inch thread (20national, 2inch long) bolts with washers
  5. NOTE: (if the blade was removed/reinstalled, tighten the blade to manufacturer's spec of 60lbs) before installing the new flywheel key
  6. remove the sheared flywheel key
  7. clean up the flywheel (wipe off all the dirt and grease)
  8. install the new flywheel key (part 611004 for toro 20016)
  9. install the flywheel (pull the bail brake handle to get the ball-brake inside the flywheel)
  10. tighten the flywheel nut to manufacturer's spec of 37.5lbs
  11. prime the gas bulb, give it a pull and mow away

My precor efx 546 makes noise like a squeaking in left pedal it seems I tried to tighten pedal but I the whole bolt and screw turn together and the other pedal makes no noise


This squeak is normally caused by a bad bearing in the wheel. In order to provide you with the correct wheel, I will need your serial number. The following link will take you to our Precor EFX 546 page.

How do i change the battery on a precor efx 5461


Replacement Parts for Fitness Exercise Equipment at SPORTSMITH Warning Notice for Battery Installation of certain Precor Ellipticals This notice provides details about the battery replacement procedure that should be considered by anyone performing this repair. Following is the warning about the battery installation for certain models of the Precor ellipticals.

Precor Elliptical Models Affected:

  • EFX C524 with serial#s beginning I7, K7, LH, SW, SX
  • EFX C546 with serial#s beginning NF,SZ, IK, IL, IU
  • EFX C546I with serial#s beginning X8, XG, Z2
  • EFX C556 with serial#s beginning NG, SY
When replacing the battery on your Precor elliptical it is important to make sure that the battery terminals are not allowed to make contact with the metal surface of the battery bracket. **Damage to the battery will occur**.
Electrical tape can be wrapped around the battery terminals to prevent them from making contact with the metal surface of the battery bracket.
Battery replacement on the EFX C524, EFX C546, EFX C546i and EFX C556 instructs you to remove the (4) screws that fasten the battery bracket to the frame. This allows you to turn the lower PCA and battery assembly away from the frame so you can slide the battery out of the battery bracket. It may be necessary to remove the nut that fastens the front retaining bracket or "L" bracket in order to slide the battery out of the battery bracket.

How to repair a 546 efx precor


Assuming the buttons are working, the numbers change on the display, and the incline works, it may be the lower circuit board or the generator. If it is a very old unit, it may be the electromagnet or the data cable that connects the two circuit boards.

Precor efx 5.17 which intermittantly stops counting strides and freezes the display


please follow this steps:
Step 1

Remove the bolts or screws securing the console to the upright assembly. Lift the console and confirm that the cable connections are secure. Remove the cover from the console's battery bay and install a fresh set of batteries. Replace the battery cover.
Step 2

Detach the ends of the pedals from the crank axles. Remove the left and right disc shields and side shields. Inspect the interior of the base unit and locate the flywheel.
Step 3

Inspect the flywheel as it turns. Locate the magnet installed on the flywheel. Turn the flywheel until the magnet passes in front of the nearby reed switch. Loosen the screw securing the switch in place. Rotate the switch to reduce the gap between it and the magnet. Tighten the screw.

God bless you

There is a clicking sound periodically coming from the right pedal while I use the machine (Precor 546i). I tried tightening the bolts but the clicking persists. Any thought would be greatly appreciated....


It sounds like it could be a faulty bearing in one of your wheels, a worn ramp or a combination of the two. The following link will take you to our Precor page. Please reference your model and serial number. This will allow you access to the correct parts and manuals for your machine.

My EFX elliptical provides an error 44? and shuts down in the middle of my work out. I notice this is only an issue when choose a course that is weight loss when the EFX has to incline and decline. When...


Precor Error 44, Un-commanded Lift Motion Probable Cause 1. Intermittent or bad connection in the lift position sensor(potentiometer).
2. Lift position sensor (potentiometer) is bad.
3. Lower PCA is bad.
Corrective Action
  1. Bad or intermittent connection of the lift position sensor (potentiometer) is the most common cause of the error 44. Inspect all wiring and connections related to the lift position sensor (potentiometer). Repair or replace wiring connections as necessary.
  2. Monitor the lift position number displayed while operating the lift in diagnostics mode. If the reading makes large changes or is erratic, the lift position sensor (potentiometer) is likely bad. Replace the lift position sensor (potentiometer) or lift motor if the lift position sensor (potentiometer) is internal to the lift motor.
  3. If the lift moves without any command entered either manually or through a program, replace the lower PCA.

I own a Precor EFX 5.33 the drive belt snapped so i bought a replacement belt and i've installed it and i can't align the other belt. How do i get the skinny belt to fit snug?


You use the two bolts that hold the step up pulley in place. The step up pulley is the pulley assembly that is closes to the back of the unit. The step up pulley slides into two grooves in the frame, then there is a bolt on each side that run down the groove into the step up pulley. These bolts are the bolts that adjust the tension for the skinny belt. You may need to loosen the other belt first then tighten the skinny then retighten the belt you replaced.
