Note: I personally had one of my eBay bearings on my idler pulley start to make noise after a couple thousand miles. I have decided to try SKF bearings instead at $5 each. Use the eBay bearings at your own risk :)
LHT videos rave about NACHI Release bearing. I decided to look up if NACHI produces 6203, & their list is a bit too long to pick out the right 1's. If you have time will you check this out? nachitech.stage.thomasnet-navigator.com/keyword/?&plpver=1001&key=all&keycateg=100&SchType=1&keyword=6203&refer=cad.nachiamerica.com
Loved the video! Very informative man. Could you post the SKF bearings product link(s) or part numbers? I think it would help a lot of us out who are looking for the SKF bearings!
I search S2ki 99% of the time for this kind of information but it's really nice to have these things in video form. I just swapped my idler bearing with your help. Thank you!
THIS IS JUST THE VIDEO I NEEDED!!!! my k24 swapped ek civic is SCREAMING for help every time i start it ahahahah. Thank you for the step by step guide, you made it very easy to understand!
I'm always using TH-cam to DIY & basically copy other people at times & learn. Your videos have helped so so much with my s2000 & I'm grateful for them so thanks 😁 👍
I like that you maid this video. It’s almost as if you read my mind because I was think of replacing my pulley bearings. I know mine are not as bad but I just want to replace them any ways. Thanks and keep the videos coming they are great. 👍🏾
A common trick is to leave your new bearing in the freezer overnight... It will give you a bit more clearance to push/tap the bearing back into the pulley.
The Amazon seller for those bearings refuses to sell them. I ordered them twice and both orders were cancelled for no reason. Just in case you see this and want to link somewhere else. By the way, I love all the videos! I've watched a ton of them and they're incredibly helpful.
Actually, I’d suggest using a small piece of 2x4 to start hammering in the bearing. Even with the closest sized socket to the new bearing, I managed to damage it. Luckily I bought spares. With the bearing a portion of the way in the pulley, use the socket with the non-fastnerer face side contacting the new bearing, and use the 2x4 piece on the other side to hammer the rest of the way.
You replaced the tensioner pulley, but wanted to know if there is any way to know when it's time to replace the tensioner itself? Thanks for the great helpful content always!
Some additional notes. The pulley that uses the reverse thread has a handy arrow embossed on the pulley showing direction to remove. Righty loosey. The cleverly chosen socket sizes that are used as bearing drivers will fully press the bearings flush. The bearing can't be pressed too far, and only the outer bearing ring will see force, protecting bearing. Even if you use a press, use the stated socket sizes to support, and to press the bearings in & out. If the specified sizes for pressing in new aren't available, make sure whatever size you use presses bearing outer ring only, and be careful not to press the bearing past flush.
The replacement alternator belt I ordered (31110-PCX-505) was way too short, yet I believe it superseded the older belt. My guess is that it's an aircon delete belt... strange considering I ordered the part using my chassis number.
for S2000, better use bearing with non-contact type of the inner ring. OEM version is contact version but special low torque seal. standard contact version is too heavy.
My S developed a sound during cold start with lots of vibration but goes away when vehicle warms up. Posted a video on s2ki and everyone told me to check the pulleys. Checked them and my tensioner pulley bearing is indeed bad but can that cause such vibrations and goes away when vehicle warms up?
Question : Is the pulley on the right with the three bolts on top, is that where the water pump is at? And are there any videos showing how to replace it ? thank you very much, to who ever answers me.
Fantastic video. I've ordered the bearings but they sent me the c3 version of the bearing. Should i return it and get the 2RS only bearing or should it be ok? I assume you don't need any high temp grease on the shafts when re-assembling the pulleys? Would love to see a video on how to replace or rebuild the common sticky starter motor grind on the s2000 in cold weather :)
Pictures make it seem like there is no cover between the inner and outer race so I'd say its a no go if that is the case. No grease necessary. The start motor grind is a very very common request. I'll likely do it this winter.
Hello DIY Guys, nice video, great content, I have question for you and maybe you could help with this. I have a Mazda Tribute 2008 4 cyl. I lost the serpentine and noticed that the top pulley was loose, so I removed it and say that the washer behind it was damaged (it's for the power steering pulley) according to a diagram I found online. The pulley is still good, not damaged. Would you know where to get that washer part without having to change all the pulleys? Many thanks, John
I only really know Honda S2000s but I would recommend looking for an website that sells OEM Mazda parts and digging through the parts categories until you can find the schematic with all the different listed parts. Good luck!
Don’t have much data yet. These bearings were off of a 2001 with 140k. I also did the ones off my CR with 150K and they were in ok shape. My guess is 200K should be mandatory.
I kind of cringed at the hammering on the bearings rather than using a press. Anyhow, if you do use a press, I wonder if it's necessary to have that mega socket to support the other side of the second pulley?
Old I know, but for the next guy, yes, still need to support underside of pulley to prevent pulley cracking, even with press. While a press is certainly better, not everyone has one. Hammering is fine SO LONG AS ALL THE FORCE IS ON OUTER BEARING RING. Hence socket sizes he used.
I'm about to replace my pulley bearings as per this great DIY, I have 2 x 6203-2RSH as per your recommendation (I believe the H denotes heavy duty seal), however it's rated at 12000rpm limiting speed... forums suggest that at max rpm, these bearings are hitting 15000+ rpm....have you had any issues with yours since you replaced the ebay items with SKF?
@@DIYGuysvideo From what I have heard, as bearings age they begin to lose the grease they were manufactured with. Its no really a good thing to have a bearing that spins like crazy. Source: Engineeringexplained mentioned it in his supercharging the s2000 video.
It sounds like a whirring noise at about 5K-6K RPM. Seems to be coming from the front of the car. It might be the clutch release bearing since that is directly correlated to the engine RPM, like the pulleys I replaced.
DIYGuys whirring like a turbo sound? changing tone with rpm up and down? if so i also have that, it used to worry me but i spent many hours on forums and a lot of people just said its normal sound from gearbox on s2k
Tons of people have done this, including me. Zero reports of bearing separating from pully. I have over 60k miles since doing this service. Mechanic is assuming the press fit surfaces of pulleys will be worn as old bearing pressed out, and new pressed in. Like many things your average shop mechanic assumes, he is wrong.
Yep. I have a feeling it is related to the clutch assembly. But I used OEM release and pilot bearings IIRC. I get a strange whirring sounds at around 5000-6000 RPM
Um, this is pretty routine work. No need to remove ground. Remove ground when doing anything electrical, or whenever there is a chance you'd short + to ground (like using wrench nearby any exposed terminals).

My bad! I assumed the link in your description was for the eBay bearings.
They are indeed for the SKF version!
Carry on 👍
Will the bearing type be stamped on the old bearing?
@@jinnnguyen7077 How did the NACHI bearings work out?
I search S2ki 99% of the time for this kind of information but it's really nice to have these things in video form. I just swapped my idler bearing with your help. Thank you!
my belt snapped on the highway diagnosed it was the idler pulley that was seized.... awesome video man really helped me out
Dude ur a life saver cause I thought my car had rod knock until I saw ur video, thanks a million my man!
Oh boy
Bro same here on my 03! Such a scary thought with f20c prices these days

Absolutely amazing between your video and LHTs video it makes this job a breeze!
My s2000 started making that exact noise this weekend. sounds like metal on metal coming from the pulley area. great video!
was it belt or pulley or something else?
I've had a new weird noise and my first suspicion was the belt/pulleys. thanks dad.
Those bearings!!! Glad you replaced them even though they weren't the source of noise.

DYI video on replacing AC compressor? To fix AC. Thanks!!!
Thanks a lot this was really great. It was extremely helpful for working on my '04 ap2
Glad it helped!
Dude love your videos! Informative and clear step by step. Thanks for helping with mines.
Thanks, I just liked and subscribed. Looking forward to watching your other S2000 videos
You replaced the tensioner pulley, but wanted to know if there is any way to know when it's time to replace the tensioner itself? Thanks for the great helpful content always!
I'd like to know the same. I have a new one ready to go along with a new serpentine belt. Is it hard to swap out the drive belt tensioner?
Clean cut explanation
Excellent tutorial.
Great information 👍

My 2004 AP2 is also showing signs of pulley and belt replacement. Thanks for this helpful tip and where to buy those aftermarket pulley bearings!
Excellent work!
Thanks for the video write-up as always!
I haven't checked my belt tensioner pulley, but my idler pulley completely seized. I should check that belt tensioner pulley soon.
LHT performance sells the Nachi Bearing that I think honda uses.
This is the nuts!! Good video! Very helpful!! 👍🏻👍🏻
Nice and easy! Don't you recommend using some Urea grease on the bearings prior to installation or is it really not needed?
Can I use the Iddler pulley bearing on the tensioner pulley? Please let me know thanks
My belt tensioner with new bearing does not spin freely? Is there supposed to be a washer under the metal cap like on the idler pulley?
The replacement alternator belt I ordered (31110-PCX-505) was way too short, yet I believe it superseded the older belt. My guess is that it's an aircon delete belt... strange considering I ordered the part using my chassis number.
lht perfomance sells the oem bearing
Wher is best bearing red or black
for S2000, better use bearing with non-contact type of the inner ring. OEM version is contact version but special low torque seal. standard contact version is too heavy.
GREAT VIDEO THANKS
You're welcome!
My S developed a sound during cold start with lots of vibration but goes away when vehicle warms up. Posted a video on s2ki and everyone told me to check the pulleys. Checked them and my tensioner pulley bearing is indeed bad but can that cause such vibrations and goes away when vehicle warms up?
Yes. Grease and metal change with temperature so it depends on the condition of the issue.
I idler pulley is making some minor noise how long did this bearing hold up?
You were diagnosing a noise that ended up not being the pulley bearings, but the bearings needed replacement anyway?
Thank you!
Question : Is the pulley on the right with the three bolts on top, is that where the water pump is at? And are there any videos showing how to replace it ? thank you very much, to who ever answers me.
Yes that is the water pump pulley. I personally haven't made a video on the subject and I'm not aware of any. Good luck

Underrated
Hopefully the creator sees this question but would you happen to know the dimensions of the washers?

What was the noise
Excellent DIY. Have noticed stats on typical mileage as to when this becomes an issue on the s2000?
Don’t have much data yet. These bearings were off of a 2001 with 140k. I also did the ones off my CR with 150K and they were in ok shape. My guess is 200K should be mandatory.
I’m just doing mine at 200k
Thanks!!
Anytime

I have not had any issues. The car mostly sees heavy track abuse as well. I’m trying some Timken bearings on my daily right now.
@@DIYGuysvideo Good to know. Your car sees consistently higher rpm than mine too, so I'll take my chances!
I would like to see replacing barings on pulling from large lawnmowers like 36 inch Kawasaki and larger like 42 inch toros thank you👍👍👍👍👍👍
I will never do that lol
The bearing doesn't seem to spin as freely as the OEM, is that normal? It is seated all the way in the pulley.
I have noticed the new bearings don’t spin as freely as the used one. I don’t think it’s related to OEM or not.

Good to know
what go pro are you using?
Probably a GoPro 7 Black here
what kind of noise was you hunting? and if it was bearings what was it?
It sounds like a whirring noise at about 5K-6K RPM. Seems to be coming from the front of the car. It might be the clutch release bearing since that is directly correlated to the engine RPM, like the pulleys I replaced.
DIYGuys whirring like a turbo sound? changing tone with rpm up and down? if so i also have that, it used to worry me but i spent many hours on forums and a lot of people just said its normal sound from gearbox on s2k
It’s sorta sounds like clutch buzz (cha Cha cha sounds) not a turbo whistle. Only happens between 5K-6K as well.
My mechanic says the belt pully will come out while driving,and he says this method is not advisable, how is it working for you right now
Works great. Ton plenty of track days on my track car and 40k miles on my daily.
Tons of people have done this, including me. Zero reports of bearing separating from pully. I have over 60k miles since doing this service.
Mechanic is assuming the press fit surfaces of pulleys will be worn as old bearing pressed out, and new pressed in. Like many things your average shop mechanic assumes, he is wrong.
The idler pulley is the same as in my Crown Victoria, lol.
😀👍👍👍
I did the same thing before. It ended up being my pilot bearing.
Yep. I have a feeling it is related to the clutch assembly. But I used OEM release and pilot bearings IIRC. I get a strange whirring sounds at around 5000-6000 RPM
When you do serious work on a car DISCONNECT BATTERY GROUND ! It neads cleaning anyway.
Um, this is pretty routine work. No need to remove ground.
Remove ground when doing anything electrical, or whenever there is a chance you'd short + to ground (like using wrench nearby any exposed terminals).
My fucking tensioner pulley fell off mid drive. Scary and stupid of me
You can also buy these bearings at lht performance.
