If you buy these,always be sure to set them to the "CORRECT" glass thickness first.

After the old bearings have been removed, how do you intall the new ones? Is finger pressure enough or does the bearing separator do this job also? Thanks!
They should just slip on the shaft and that's it.

you can flip the separator over and use it to help press the new ones on if they are a little tight.
every one is a little different. so some slip on no problem, others need a little help.
the separator can be squeezed to where it touches the inner race and pushes on the race to press on the shaft.
this is better then pressing on the outside of the outer race.
if that helps?

Thanks, I am about to order the new bearings and just wanted to make sure I know what I am doing before starting this process!
I know it took some pressure to get the bearings off my MP10, so it looks like it would take some pressure to put them back on. Are all of you just pushing these on by hand? I just ordered some Boca Bearings and want to know if I need a special tool before they arrive. The bearings I ordered were SMR147-ZZ #5 Radial Bearings

If you find the fit too tight, put the rotor (in a ziploc) into your freezer for an hour, and put your bearings in the oven at 120 degrees for 10 minutes....they will fit together easily.
I had a noisy MP10 and went to Ebay after reading this thread. I replaced them but they didn't seem to do much and were very noisy. I lived with the noise for a good year until today I replaced them with a pair from Boca Bearing. The pump now is a lot quieter but still noisier than it's slave (which has never had any bearing replacement). I think they need some break in time but we'll see...
One video which I found helpful along with this thread is http://www.youtube.com/watch?v=eAVawLXNssw
He used a framing square to free up the back bearing which I too could not get the bearings free until I saw this.

I just finished fixing mine and remembered this thread so thought it would be good to post the results.
I too had a noisy MP10 that I disassembled and found the front bearing went bad. I ordered four bearings (two for spare in case my other MP10 kicks it) from boca, SMR147-ZZ #5 and replaced both the bearings in the noisy motor. Hooked it back up and i'm amazed how quiet it is now, much quieter than it ever was even brand new. I cant hear it over the other MP10 and its making me want to replace those bearings just for the sake of the noise.

I would just because I can not stand knowing how much quieter the new bearings are over the other motor.
Thanks for this thread, i got fooled into buying an used mp10esw and it been noisy...
Im looking into buying some Ebearings...
Oh and the firmware need upgrade, try n find a guy who owns one with the proper upgrade... another problem i dont need...why i cant download and upgrade it myself is beyond me...
But before i leave, here's my thought on these pumps...
For 100$ more u get a Tunze 6055+controler
Always whisper quiet, never breaks down, but the biggest thing is
NEVER NEEDED TO OPEN ONE UP!
Yup... Never again!

Sorry I don't spend much time here, but great thread.
I'm not convinced about the sound performance of steel vs. ceramic bearings. I went through the whole thread and it looks like there was just 1 specific instance of someone noting that their ceramic replacements were too noisy. I need to replace the dry side bearings on one of my MP40's and I'll post a decibal rating of the ABEC5 ceramics I just ordered.
Also, these are $300+ pumps. You can pick up a bearing separator for about $10 on ebay It's definitely a worthwhile investment IMO. It's painful for me to read about broken magnets.
There's Android and iPhone decibel measuring apps if anyone else wants to post their output. It's not super accurate but is better than the human ear from a technical perspective.

looking forward to your decibel rating posts. and thanks for the tip on the android app. i'm going to compare the ratings on the used mp40s that i picked up to your "after replacment" postings.

Because of this fantastic write-up by dahenley, I purposely purchased a noisy MP10 at a fantastic price. I ran into the problem in reading every post here, and trying to figure out which brand and type bearing to purchase. So I re-read every post again and this time summarized any post that included the bearing type and a comment on noise/performance. NOTE, FOR MP10 ONLY. I've also included a link to that bearing and the respective price. Here's what I found (my comments in parentheses):
Post 353 (Zypharus): Boca, SMR147-ZZ #5 "œquieter than brand new" (Note ABEC 5) $8.95/each
Post 329 (JAustin): RC bearings.com SMR687ZZ "œquiet as ever"
(I could not find this bearing on RC's site. However, I found an earlier post that had THIS LINK, but this stated "œNot Found.")
Post 311 (gregzz4): ACER 7X14x5MM Ceramic Ball Bearing "œnoisy" (note, these are ceramic) 8.99/each
Post 298 (Jarred1): No Brand or site, just says MR147-2RS "œI can only hear the pump when I am right next to it"
(I found Boca carries this number: MR147-2RS. Interestingly, according to the Boca site, it's only an ABEC 1)(Since found that the bearing number is for the bearing only"¦.this could come ABEC 1 "“ 7, dependent on the bearing. The ones I found on Boca were 1's.)
Post 229 (shaggss): VXB 687-2RS (off of ebay) "œThey are now dead silent" (Could not find ABEC ranking)(note that these have blue seals) $6.90/each, free shipping
Post 218 (kakalakasha): Boca SMR147C-YZZ #5 NB2 "œonly SLIGHTLY quieter" (note these are ceramic)
Post 170 (FiReC): VXB 687-2RS "œstill loud as hell"
(note that these are the same VXB number as the ebay bearing above, but differ in that the ebay ones have blue seals and these have black seals.) (Have since found that the color of the seal signifies the type of grease"¦"¦.Blue seal is supposedly for cold weather applications (i.e. snowmobiles))
$4.95/each (with shipping, about $7/each)
MY HALF-COCKED UNSCIENTIFIC ANALYSIS OF BEARING PERFORMANCE TO HELP DETERMINE WHICH BEARING TO BUY
Ceramic just sounded like a problem when it comes to noise. I have no doubt that these are some of the best bearings going, but when one of our criteria is noise, they are a potential problem.
With the remaining steal bearing, here's what I did: Any with reports of noise were immediately eliminated. I also eliminated those with an ABEC rating of less than 5. That left two bearing; Boca's SMR147-ZZ #5 and Ebay VXB 687-2RS (unknown rating.)
I was originally leaning towards purchasing the ebay VXB blue sealed bearing (because of the report of silence and price"¦shipping included), but because I could not find ABEC numbers, I was turned off. The only one left was the BOCA SMR147-ZZ #5, but the lack of shipping info scared me. When I called them they told me anything over $12 ships for free (USPS). So I ordered these two bearing from BOCA tonight.
While I wait for the bearing to arrive, I'm using this great post by dahanley and THIS video posted by toofasst, that shows how to open up the MP10. I've also found the companion video that shows how to put it back together HERE.
When the bearings arrive from BOCA, I'll let you know how the re-assembly goes.
