You may be unlucky enough to have have acquired a Dyson DC23 (called a DC32 in Australia) that needs stripping down to replace the motor.
That being the case, there are a few things you need to know about it. The Dyson DC23 is fitted with a YDK motor which is very similar to other Dyson YDK motors, but it is a unique one. A generic YDK motor will not fit.
The numbers you will find on the 240v motor are YDK, YV-16K24B and possibly 8C29.
The difference lies with the assembly at the top of the motor. There is a fan arrangement sitting on top of the motor which is held in place by a clip on the spindle. Here is what it looks like:
At first glance, you may think that you can just transfer this fan unit over to a standard YDK motor with a spindle; such as you might find on an upright machine. However, closer inspection will reveal that the spindle is thinner and has a flat side (to drive the extra fan). This means that unless you fancy trying to grind the spindle down a little, and re-creating that flat side, they are simply not interchangeable.
The drawback with attempting to modify a standard YDK motor in this way is that your modification (unless done in a machine shop) will likely not be exactly central. As the plastic fan this drives is very slim and delicate, it wouldn’t be very long before it broke up because it wasn’t spinning true.
Can you do away with the fan? Well, you probably could – in the short term at least – but, I wouldn’t. The exact purpose of this fan is unclear. We think it is to provide cooling to the top bearing. Whatever it is for, it is to provide extra cooling to something. Dyson’s design engineers are not daft. They don’t design this stuff on the back of a fag packet any more. That extra fan assembly is there for a reason; so we must assume its needed.
Now you are trawling the net trying to find a motor no doubt. And you have drawn a blank up no now haven’t you? This is because Dyson do not supply the motor without the fan assembly – it comes together with it installed, in the housing. Not enough DC23’s were made for anyone to bother making after-market motors so you are stuck with buying a genuine one. However, Dyson will not sell you one. You will have to get one from an independent Dyson dealer if you want to fit one yourself.

Now all you need to do is strip the bugger down. And that is a pain in the backside compared to stripping down other Dyson cylinders. Good luck.
