Can a Miche Primato Rear Hub Be Serviced Easily

OK so the mercian is now complete, and took it out today but the rear hub which is part of a used wheel set doesn't move as smoothly as it should easy it easy to service myself and will i need any special tools? thanks in advance

I've been meaning to ask about this myself. i know that you just need to replace the cartridge bearings. but i'm not sure how easy this is. not sure if you just wrestle them out and replace or if there is a specialist tool...

Are there any particular cartridge bearings? need to get this sorted soon

i would imagine they are 6000 series of some kind, there will be a code number on the seal something like this: 6002rs get the number and go to your local bearing place and get some

pretty sure they are 6000 mr smith. is it a case of just levering them out?? almost like a skateboard wheel.

you need to drift them out, levering isn't good for your hubs. usually pushing the axle out brings one bearing with it and then you drift the other out with a socket, you use the same socket to drift the new bearings back in, make sure the socket bears on the outer part of the bearing not the seal otherwise you will knacker your new bearing

thanks mate. the concept of 'drifting' sounds interesting. softly, softly!

cheers guys off to go and get some cone spanners

Hi a little bit of info for future reference on this subject; the cartridge bearings on the primatos are not so straightforward to get out - well mine at least. This is because it's not as simple as taping them out from the inside due to the bore of the hub being the same as the bearing. So I was scheming a way to get them out, and came across this thing:

So i've got one ordered and will post here if it's actually any good - you put the flanges in through the bearing, they expand and then you belt tap it out with whatever. Looks simple enough and cheaper than a proper heavy-duty bearing puller.

OK editing now - this thing works and is good. Buy it here: http://cgi.ebay.co.uk/Enduro-Cartridge-Bearing-Puller-Tool-8-25mm-ID-Range_W0QQitemZ360176929506QQcmdZViewItemQQptZCycling_Parts_Accessories?hash=item53dc37cae2&_trksid=p3286.m63.l1177

Re: Richard, how did you get on with that tool? Any good?

tapping the cartridges out of the primato is a bitch as r cheese said .. i knocked the corners off several screwdrivers before my g/f found that using a pitlock skewer worked .. they are good for something at least!

word of caution .. when inserting the new cartridges make sure that the pressure is applied to the outer race .. if you apply the pressure to the inner race you'll pit the bearings immediately (i've done it) .. my solution was to pick up some appropriately size washers from the hardware store and then place them on the axle on each side outside the cartridges and then just use track nuts to tighten both in at same time .. works a treat but one other word of caution if you do this .. use either steel washers or multiple washers as one cheapo washer buckles under the pressure required to insert the cartridge and hence applies the force to the inner race

hi.
a friend told me the same thing, i have been trying to ignore the clicking coming of the rear sealed hub for a while. time to try. will let you know how i get along.

ive been getting a tapping/grinding noise on my bike the last couple of days. turns out that it's my miche primato rear hub (pistard wheelset). the axle would not spin when i took it out and try to turn it by hand.

do i require a 6000 or 6001 bearings? miche website says i require a 6001. or is that's just for the primato road hubs?

6001

I asked the same question here and got good answers, including what size cone spanners you need...

My miche primato hub now has a slight 'tinkling' sound when the wheel is rotating. This has happened after a ride in the wet, so I'm guessing most likely it is the bearings. They are only 8 months old though, which is disappointing. Are the miche hubs prone to this? I thought they'd be pretty durable as loads of people ride them and condor use them on their fixed bikes.

They don't have good shields to keep crap away from the bearing seals (don't need any, it's a track hub innit?), so they can get destroyed quite quickly by dirty weather.

yeah, but I've used an Ambrosio and a Suzue hub in the wet loads without any problems, and Miche are sort of standard on road fixed bikes (condor, wilier, etc)

I've had two Miche wheelsets; on the first one the bearings went 'tinkly' within about 6-8 months. The wheel is still going strong, aside from a slight catch in the bearings.
The other has been buttery smooth for going on 2 1/2 years now. Perhaps the manufacturing's a bit inconsistent? In any case, IMO they're still pretty good hubs considering how cheap they are. My 'system ex' hub was knackered after about 3 months.

i guess I'll replace the bearings and hope they'll last a bit longer this time. Decent enough hubs though.

hmmm.

Can you evade the nursery period?

Don't try. Really. It's a public forum which means everyone can see you do it, and if you post 5 meaningless posts in an attempt to sidestep the nursery chances are that someone will report you... when that happens, I will ban that account permanently. You're free to register again, but then you start the nursery again too. So don't try, we're not that dumb and as this is our one piece of moderation it's purposefully harsh, really, don't try

so quit with the inane crap.

lots of bad miche bearings from what i understand from my friends, anyway to get the bearings out you could go to a skateshop and use the device they have for taking out bearings, i guess you can use it to push them in too

BETD goldtec bearing that fit Miche hubs:
6000 2RS - 10mm x 26mm x 7mm
6001 2RS - 28mm x 12mm x 7mm

Are they compatible? I see the last part being 7mm instead of 8mm. I am about to order some sprockets from goldtec, along with a derailleur hanger anyways so I'm thinking about getting a spare set of bearings to have before I get the miche wheelset.

I haven't decided yet regarding the wheelset:

1. Miche X-Press Pista/Strada Fixed/Free Wheelset;
   http://www.mountainbikecomponents.co.uk/items.asp?CategoryID=15&Name=Goldtec+Track+Hubs
   
2. Goldtec hubs laced (by the factory) to Open Pro (36 front, 36 rear), pro lock nipples, sapim spokes. I guess DT spokes over Sapim would be just bling (2x20 euro), please correct me if i'm wrong. Since the bike shops around here are very terrible with building wheels and truing them I hope those pro lock nipples would do the job of holding still for decades.
   
   

the miche wheelset can be had for 195 euros, the goldtec wheelset sums up to 283 euro. that 88 euros difference really does matter regarding my budget and having the option of a freewheel would be nice. but there is another thing, the width of the rims... would the 622x13mm miche rims go well with 28mm durano tyres? if not then i'd give miche the finger for not offering wider rims to the general public and go with the bloody french mavic.

I hope you don't mind me being slightly off-topic.
Thanks.
