Help Needed Plz...1100 Watt Induction Motor Stopped Working

Hi all, please dont shoot me if I am posting in the wrong place, I have looked but not sure where would suit my question..
I am a carpenter by trade and I have a Ferm Tablesaw(Ferm have now gone bust) the saw has a 1100W induction motor. I have used the saw for around 4 years but it has not had hard use in this time.
I was using it last week and out of the blue it just stopped running with no smells or strange sounds, since then I have not been able to get it running.
I have searched the internet for answers and have purchased another capacitor(second hand) which is of same spec as original.
I installed the replacement capacitor and still the motor will not run. I have now taken the motor apart and looked at it closely and it looks to be in good condition.
I cant see any broken wires(windings) and spindle is straight and bearings are in good health. When I directly put 240 volt to the motor it tries to turn and I can hear the power hum(usual) but even if I twist it it will not spin up.. it sound as if it is trying but not enough power to kick start it...
As you can probably tell I am not at all clued up with these kinds of things and could really do with some advice/help to find the fault and possibly repair the motor if possible.
The Capacitor is 3" high and 1 1/2" across and has 2 wires protruding from the top,
The capacitor specs are:

FACON
20uf +/- 5%
450Vac 50Hz
EN60252


1. Do you think it may be a bad capacitor?
2. How can I check the capacitor?
3. What is my next move?

Any help would be great fully received...
