I have a 2.4kW electric motor in a garden shredder. It has a broken radial
cooling fan that is a push fit onto the rear arbor. I don't think that it
is available separately as a spare - only the whole motor.

Does anyone know a possible source of replacements? It is about 150mm in
diameter, radial because it can be used in both directions and plastic.
Fits on a 12mm arbor.

I would be very surprised if you could buy a spare one. It is also a
very small shaft for such a relatively powerful motor which might make
robbing one from a defunct motor difficult.
I managed to get one replaced on a brand new motor that was delivered
with a fin missing.

If you happen to have a local back street rewind workshop they might
have something in the scrap bin from a motor taken to them that was
beyond economic repair.

Failing that, repair or make a replacement.

Miles Tools are good on spares, although you haven't said what make.

You need a fan and maybe a lathe. Any old rubbish will fit in there
and probably work OK, but it will need to be securely fastened and
well balanced.

In extremis, throw the fan away and mount a new fan externally (PC
cooling fan etc.). You don't need a specific fan, just to achieve
airflow.

Yes, but beware with pc fans, they run far slower than a lot of mains
motors, so similar size wuold produce nowhere near enough cooling.

Bearing Services,now called Brammer sell fans on there own,so do most
of the proper power transmission places.
