After watching your video, I decided to try an alternative to tearing down the whole assembly. 3/4” e-clips can be snapped in place on the backside (inner side) of the bearing without taking the bearing out. I put one on each side and the problem is gone.
NOTE: I had very similar noise issue on Precor EFX 5.19. This was after it had been moved and maybe banged around a bit. It turned out that the washers were fine, I only needed to center the magnet better so that the disk did not hit it as it spun around. The magnet had apparently worked its way to one side a bit, probably from the move. Since this is a much easier fix than replacing wave washers, you ought to see if this will work for you. The EFX 5.19 is very similar to the 5.23, so the covers are removed the same. You actually only need to remove the left side cover to adjust the magnet (left if you are on the elliptical facing forward). This is because, though the magnet is held on by two hex bolts, and you probably would need to remove the right cover to access the right hex bolt, you actually only need to loosen the left bolt for the magnet to slide side to side. I don't know why, but there it is. Maybe just loosening the right bolt without the left would also allow it to slide, I don't know. Anyway, I was thinking I needed to replace my wave washer, but when I removed the rear covers, I could touch the main disk and see there was no play or wobble as you'd find if the wave washer broke. It was tight as a drum. Then I looked at the magnet to see if it was centered, and it was actually far to one side, Far is relative, the space between magnet sides is, like a quarter inch or less. On the right side, I could see about a millimeter gap between disk and magnet, on the left side I saw no gap. You can try to center the magnet by hand, eyeballing it -- that's what I did -- but I'm not sure you need to. After I centered the magnet by hand, as best I could tell, I decided to ride the elliptical before I tightened the left bolt of the magnet, to see if the noise was fixed. At first, the noise was still there, but quieter; however, as I rode, the noise lessened and then vanished in just a few pedals. I realized that the spinning disk had nudged the magnet to the optimal "no contact" position all by itself. I then stopped pedaling, tightened the left bolt of the magnet, replaced the circuit board cover, and replaced the left rear cover (I had actually taken off the left and right covers, but on retrospect, I don't think I needed to take off the right side for any of this). The noise was gone. Note, for the EFX 5.19, the magnet is not on top, like in this video of the EFX 5.23. Instead, it is near the ground just a little in front of the disk, and the bolts are not 13mm (the size magnet bolt stated in this video) but were much smaller, though I do not recall exactly what it was. Oh, and the magnet placement on the EFX 5.19 makes it almost impossible to access the bolts, even with a socket wrench. Just in front of the magnet, blocking access to the heads of the bolts, is the circuit board covered by a hard plastic cover. If you take that cover off -- pushing on four places where it latches to the circuit board and lifting -- you can access the left bolt pretty easily, but some of the larger circuitry on the right side still makes it very difficult to access the right bolt, though luckily that is not needed since only the left bolt needs to be loosened. If you have the EFX 5.23, it looks like you won't have this particular issue. Anyway, I really need to give credit on this to omask7, the guy who made a different, 2-part UA-cam video on fixing his EFX 5.23 rattle with washers, because he said in the second video, around 1:45, that he had noticed that the magnet could be adjusted if you loosened the bolts, and he had done his best to center the magnet when he reassembled the elliptical. That is what gave me the idea, when I saw I did not have a washer problem, to see if re-positioning the magnet might fix this. Without his comment, I'm not sure I could have figured this out.This fix is actually 20 times easier than replacing a washer, so I was lucky. I am posting this info here, since in all my googling, this video and the other, two-part video on fixing a rattle/grinding noise in the 5.23 are really all that came up. So I expect anyone who has my problem and wants to diagnose it will find their way here, and maybe they'll see this comment and it will help them.
Thanks for this, perfect information. The bolt is an 8mm, and if you remove the cover, you can unsnap the power connector that is in the path of the right bolt and use a ratchet on both sides. I don't see any instability, so I think my magnet has just shifted over time. I've recentered and don't hear any noise, but I suppose tomorrow morning will be the acid test.
Thanks for the great video that helped me diagnose the problem when I found the piece of broken wave washer on the floor. Am in Nairobi now with no mail service from the US so will need to do this after we move back, but at least I know what to do (and won't break my Precor trying other fixes).
The parts diagram only shows the wave washer on one side. I can see the washer on one side of my elliptical but there is nothing on the other side. Did you notice this and decide it would be better with the wave washers on both sides? It makes sense there should be something on both sides to keep the disc centered. Edit: I found my manual and it is different than online manuals. The paper manual shows 2X the wave washer. Now I'm just curious why my machine just has one. I would think I'd at least see a broken washer.
Hey! Great video. I was wondering maybe somebody has the correct sizes of the flat washers and wave washers? Like diameter atleast. Couldnt find in the manual :/ I have the same problem and would try to buy them locally.Thanks!
@@shinzo222 I ordered from Precor Parts Direct online. The part number I used was PPP0000WAHNN080021 for the wave washer and PPP00000WNNN075001 for the regular washer. I actually looked at the email receipt from when I purchased it and it some dimensions on it, this may help you: WASHER,WAVE,NONSPLIT,.800,STL WASHER,SHIM, .75X1.50X.010 THK The flat washer is probably .75" ID, 1.5" OD and .01" thick. I'm guessing the wave is .80" ID.
I don't recall needing to use a hammer or anything, I definitely would have commented on that in the video. Pretty sure I was able to get enough of the arm on to thread the nut and just tighten/use the nut to press on the arm.
So you are saying that your elliptical came from the factory with one wave washer and two flat washers on EACH side? Mine only has a flat washer on one side and a wave washer and two flats on the other side. I just had to replace the wave washer and the disc has too much play in it and still hits the magnet.
It's been awhile now, I remember they were broken when I took it apart so hard to tell 100%. Re-looking at the parts diagram just now, it looks like what you describe may be correct. That said, I haven't had any issues running wave washers on both sides. Mine is still working great with no noise.

Good tips, thanks for the info.
Thanks! I’ll try this first. Thanks for posting it!

Glad to hear, hope you can get it fixed. Mine is still working great!
Thanks for posting this video.. found a broken wave washer in mine. Glad I looked at this video before I started to try and bend something or other.
Glad to hear it helped! Hope you can get it fixed soon.
Thanks for recording this. I just broke mine and will try to fix it.
Both clever AND brave.. Now can you tell me how to find and replace fuses on this monster?

I don't have that info, sorry. I don't think you could determine the ID of the washer required without basically fully disassembly.
VegascomJeff oh ok. So did you contacted precor and asked for those washers that they go on that axle ?

VegascomJeff nice! Thanks. I will try to look up those!
How do u reinstall the crank arms back on the shaft? Did you use a hammer, or is there some way to press them on? thank you,
I don't recall needing to use a hammer or anything, I definitely would have commented on that in the video. Pretty sure I was able to get enough of the arm on to thread the nut and just tighten/use the nut to press on the arm.
@@VegascomJeff Thank you Jeff... much appreciated!
Do you happen to have the model number of the wave washer? I have this exact problem and I see two different options for the wave washer.
It's precor part #PPP0000WAHNN080021. That's for the EFX 5.23.
So you are saying that your elliptical came from the factory with one wave washer and two flat washers on EACH side?

has this solution held up?
Yup, no issues since this repair.
@@VegascomJeff Bravo!
Wish there was better lighting so I could see what he's doing.
Followed @derickhass8437 recommendation about using 3/4” external E Clip.
Fixed the problem. Thank you.
