Headset bearing misfit

Had a quick search for this but couldn't find any good info.

I've just replaced the headset bearings in my PX SL Pro Carbon. I was reliably informed that they were 41.8mm (outer diameter) 45/45 type sealed bearings. I ordered a couple off the bay and fitted them the other night.

The problem I've encountered is that the split ring which fits inside the upper bearing (and upon which the seal cap and stem sit) doesn't seem to go as far into the inner diameter of the bearing as it did previously, and therefore the seal cap sits slightly proud of the headtube and there is a ~1mm gap.

Is this a problem? Did I buy the wrong bearings? Can I get a bigger cap, or seal the gap somehow?

Any help appreciated!

    Your old bearings may have been 36/45 so the existing split ring is now sitting in a different position. Or it could nothing to do with this, and just that the new bearings have a smaller champfer, so the existing split ring is now sitting a tad higher.

    Reckon I should just buy a 36/45 and try that instead?

    Or take the Dremel to the split ring?

    can you look at the new bearing and the old bearing and see the difference?

    not all split rings are exactly the same - you could try a different one..?
