Shame. Is that the Dyson you drove to Stoke to collect?
I've stripped loads of DC07's down, its very easy, and an aftermarket DC07 motor is only about £20 to buy.
The YDK screamer motors fitted in the DC07 and DC14 are the same, but are not the most reliable, and yours has blown the armature windings by the sounds of it - producing a popping sound when on, and an extremely bad electrical burning smell.
I have bought a few like this as spares or repairs, replaced the motor and sold them on again.
DC07's are 2 a penny on EBay, and parts are plentiful, and cheap. They were about the most popular Dyson ever made, and had a very long production run between 2001 and 2008.
They have the same power as the DC14, but the DC14 has more vent channels in the floorhead, so making it easier to push around than the DC07.
Older DC07's were renowned for fragile and brittle plastics snapping off all over them, and also for the cyclones clogging up, necessitating the removal of the top of the cyclone housing for cleaning. They also suffer from torn stretch hoses, and rips in the lower duct hose from the floorhead to the changeover valve.
Clutches are reliable, but the clutch belts stretch over time and eventually start slipping, requiring a new clutch as only one of the belts is replaceable (the one from the clutch to the motor).
