Pelissier 2000 hub cartridge bearing cleaning/replacement

Hi picked up a nice pair of these hubs the other day but the rear needs at the least a clean and new grease pumped in, at worse the cartridge bearings replaced.

I'm curious if anyone has done this before for these hubs, if there's anything particular to look out for.

So at first I'm considering just cleaning them out and seeing how they roll, as the grease is so dry that may be all that's needed.

Here's what you see when you open one up:

It looks like the brass bearing cage ought to lift off giving better access to clean out the internals and pump new grease in, but at least with finger nails alone it refuses to budge. I'm not keen to get in with anything more abrasive if it's not going to come out and just bend.

Here's a cut-away/schematic of the hubs:

It's not clear if the axle is stepped internally to allow you to easily hammer out the bearings. Is there a fool proof way to get bearings out of a hub regardless? I don't want to just be hammering pointlessly on something that won't ever budge :)
 
Re:

Well FWIW the insides look like this:

Doesn't look quite like the schematic so either they changed them about or perhaps they were replaced already at some point.

Races seem fine but perhaps the bearings could do with a replacement.

Any ideas what their type is, have never seen a set like this before.
 
The bearings should have a ID number on them usually on end the outer bearing case, so you might have to remove the part still in the hub.
Your first photo shows E10 on the bearing is that part of the ID number??
 
The bearings in your hubs are called "Magneto Bearings" or "Otger Bearings", E10 is the size and the part number, the outer race (OD) is 28mm X inner race (ID) is 10mm. Here is the NSK spec sheet for this type of bearing, http://www.bearing.co.il/Magneto%20Bearings%201.pdf
These bearings (different size) were used in Maxi-Car hubs and lately in Curtis Odom hubs as an option, and are known for having an extremely long life when used in bicycle hubs.
If your bearings are running rough after servicing, replace the bearing set in its entirety, do not try to reuse the outer race. Magneto bearings are not inexpensive, buy a name brand bearing (NSK or SKF) there is a difference, any good bearing house can get them within days.
Heating the hub to 200 deg. F will ease the outer race removal, coat the outer race with anti seize and freeze the outer race at installation, or let a good LBS do the outer race installation. With a good grease and regular service your rebuilt hubs should be good for a REALLY LONG TIME...

Re:

Spot on advice from Blackbike. I would only add that if you have trouble extracting the outer races, you would probably be better off taking the hub to a motorbike magneto specialist to have them removed. Most bike shops, certainly in the UK, wouldn't know where to start with bearings like that! :LOL:
 
Re:

Very old thread, I know...

Just wondering if these hubs do also sport the same type of labyrinth seals like the Maxi Car hubs?
