Pulley Bearing Inspection & Replacement

Pulley Bearing Inspection & Replacement | Honda S2000

Hey everyone, today I’m going to show you how to inspect and replace the bearings for the idler and belt tensioner pulleys. Both of these pulleys are driven by the serpentine belt and over time the bearings for these pulleys will wear out and begin to make noise. I personally replaced these on my car because I was hunting down some noise coming from the engine bay. It ended up not being related to my worn pulley bearings but I figured this video might help someone else out.
Note: I personally had one of the eBay bearings start to make noise on my idler pulley. I have since used SKF brand bearings instead. I'll update this as time goes on...

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

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.

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.

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 :)

@DIYGuysvideo 5 жыл бұрын

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.

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.

I idler pulley is making some minor noise how long did this bearing hold up?

@russelloppenheimer3970 Жыл бұрын

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.

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

Yes. Grease and metal change with temperature so it depends on the condition of the issue.

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?

@russelloppenheimer3970 Жыл бұрын

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.

@c0deye1 6 жыл бұрын

what kind of noise was you hunting? and if it was bearings what was it?

@DIYGuysvideo 5 жыл бұрын

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.
