Rayburn 499k MX Lock out on both burners

Those are fine John - I have a new motor/cap coming will see how it goes from there and update

If you decide to test the old motor on the bench, it should start up quickly and in the same direction every time...I like to test the torque, too so I hold the motor in a vice and grip the spindle whilst switching on.
On a couple of occasions Ive been able to stop the motor from turning!
Check the motor to pump dog drive too - I cant remember what it looks like though.

The pump drive dog on this burner is very flimsy. A source of many problems, but there was a modification on later models that improved it.

Is that the splined coupling? Its been a long time since I locked horns with this one, and have no desire to repeat the experience

The original was a very short triangular job.
The worst aspects of all these cookers is degradation of the combustion chambers often caused by overfiring as a consequence of poor service regimes and clogged baffles. It did not help that originally that the two layers of each baffle were the same width, and jammed in the heat exchanger. The right hand ones are also under the hob and you can't pull them effectively.

Update on this - New Motor and cap fitted (motor is now slightly different with the cap built on - different make) -- Fired up first time and sounds a lot healthier
Thanks again everyone

Result!
So pleased you are up and running again. When you feel inclined, do remove those baffles some day for a decoke
