Fulcrum 5 bearing replacement

dawh00

Hello All,

The bearings in my Fulcrum 5 back wheel need replacing. They are so stiff they hardly move now.

Two questions

1) Any ideas where I can get replacements &

2) How do I get the old ones out? (I've got the freewheel off & axle out already)

Thanks in advance

Should be a pretty easy job to drift out the bearings. What year are your wheels? Replacements should be pretty easy to get hold of if you know the code number.

Looks like all the Fulcrum R5's use 6001 2RS bearings.

To fit them - a long bolt, nut and a few washers is all you need to pull them in as they are an inference fit. Just make sure they go in straight when you start tightening up.

IIRC the bearings are 6001-2RS...but dont buy till youve checked. Pop an old bearing out, the number will be on the seal...you may be able to see it while still in the hub.
Where from ?...there's plenty of online retailers, do a google for the right number, there'll be plenty of sellers.
Or, locally from your local (duh) bearing supplier. Probably a bit more expensive that way bacause they will sell better quality bearings.
Or, buy SKF 6001 (if thats the number) -2RSH or -2RSL...this denotes low friction seals, and that is noticeable.

I fitted SKFs to mine, they pop out easy enough with a hammer and drift. Lay the wheel flat so the hub is supported while you knock em out.
To get the new ones in, you ideally need some studding (8 or 10mm) , nuts and washers or spacers, ideally JUST a tad smaller than the OD of the bearing. Sockets, washers, anything. Its a bit of a handful to get the bearings, washers, studding and nuts all held just right, then tighten the nuts to draw in the bearings. Beware them going in slightly skewed. If they start to, stop...and carefully drift them back out and start again. Be aware you can easily damage new bearings by exerting excess force on the inner ring. Thats why you want the pulling action on the OD of the bearing.

Or i suppose you could find something like a socket, again just a tad smaller than the OD of the bearing and drive them in using the socket and hammer.

fast as fupp

they will go in easier if you put them in the freezer for a couple of hours before fitting
