Bearing puller and press

nigelgos

It seems you can spend £25 on a puller set or a few £100. Has anyone got a recommendations on a set for hub overhauls?

With the press, i'll probably attempt to make my own from a rod, washers and nuts.

From my recent experience, a homemade press (and subsequent use of) is a doddle.

It's removing the old bearings without damaging the cups/casings that is troublesome.

Something like this...?

Is there anything I should be looking for in a kit?

A lot depends on which hubs you are planning to service. And also whether you are talking about replacing the main hub bearings or the freehub bearings or both.

From experience I know that the Novatec 486SB has an axle with in-board flanges and that allows you to use the axle itself to drift out the main hub bearings. Never tackled a freehub bearing replacement so can't comment on that but if you search around I recall several threads that reference servicing various types of freehub.

On a more basic level this video shows how to replace the bearings on a Hope Pro2 hub and the guy just uses a metal punch/drift to knock out the old bearings.

Some info on the hubs might prompt a response from someone who has direct experience.

Fulcrum5s - the inside freehub needs a puller I think. I'd like to do the freehub and wheel bearings. I think the one I linked to would do the job, I'm just after a nod from someone who knows

I use a similar kit. The quality of the tool isn't fantastic, but for work on bikes it's plenty strong enough. One thing to watch out for is the smallest size collet on the kit you linked is 11mm- some hub bearings are 9mm and 10mm. I'd choose a tool with a smaller minimum capacity as it might be more versatile for bike use.

If the bearings you are removing are to be scrapped, a simple drift/punch could be used.

It does depend on the hubs yij are dokng. Miche main bearings can be done with very basic tools but other cannot. I use the wheels manufacturing bearing press and extractor set. Thata few hundred pounds of tools by itself but it never makes a mess of a bearing install even in freehub bodies which is alot harder than pressing in bearings into the main shell.

Sounds like your pretty clued up in the art of bespoke tooling already, but just in case, try a socket the same size as the outer cage, do not push on the inner or the seal, this might give less deflection and a better result than a washer.
