What are the specs of the sea water pump bearings?

[Krumelur]

I'm refurbishing my old seawater engine pump. Unfortunately I had to destroy the two ball bearings because they wouldn't come off the shaft.
The part number is 860202 but these are €45 PER PIECE (!) with Volvo. This is silly.
Does anybody know the specs of those bearings so I can order after market parts?

Note: I know there are repair sets but I don't need an impeller, no o-rings, and no screws. So I'm hoping to get away cheaper by ordering parts separately. (This repair set here is about 60 bucks including shipping: https://www.poseidonmarine.eu/products/sea-water-pump-repair-kit-for-volvo-penta-d2-55-d2-75-3583089-impeller-21951346?lang=de)

Plenty of bearing suppliers. Read the type off the bearings you destroyed (or the photo you linked - zoom in, you can pretty much read it off their photo - 6003 2RS if I'm not mistaken). Measure dimensions of the other parts to confirm size (inner and outer diameter and width).

How smart reading it from the zoomed in picture. Respect!
I'll double check the measurement.

Quick update: I was able to get all parts from my local "goGlas" dealer here in Germany.
Total: €20 !!

Pump is working and I'm actually contemplating putting it back into operation and keeping the aftermarket one as a spare part.
