ANTLIA AN-2021 compressor shaft locked

by David

I have an ANTLIA AN-2021 21 Litre Air Compressor bought in Australia and brought with me when I had to return home to Scotland for family reasons.

I use it mainly for topping up the tyre pressures on two vehicles.

Was working fine until yesterday but now will not start.

When switched on (briefly) Motor just hums. Took off cover to check capacitor and found that direct shaft is locked.

Pressure is empty, condensation drained and oil level on red spot in sight glass.

How can I free it.

I am not very mechanically minded. Can you help, I am a pensioner and cannot afford to have it 'looked at' professionally.
Many thanks,

ANTLIA AN-2021 locked up
by: Bill

By locked I am understanding that the pump itself is locked up, the motor shaft cannot therefore turn, and it's preventing the motor from starting.

The connection of the motor shaft to the pump must be removable, as it had to be assembled in the first place.

Can you see if you can separate the two and then, by trying to turn the motor shaft by hand, you can determine if it's actually the compressor motor that is seized, or the motor works fine when not connected to the pump, and it's the pump itself that's locked up?
