Hi there, a forum lives and dies by its community so here is my contribution.
I recently had my dc41 yoke assembly break and Manchester Vacs supplied me with a new one, here's how to fit it.
The first and most important tip I can give is do not do this job on the glass dining room table, my wife pointed this tip out and continues to do so every 15 minutes or so.
You can see in the picture the yoke assembly I'm about to fit, it's quite a big piece.
After removing the filter cover wheel and the filter itself you're left looking at this on the left hand side of the dc41. The bit in the middle of the hole in three pieces is the broken bit of the yoke assembly, undo the five 'star drive' screws you can see in the picture.
You'll then be looking at the below so you also need to take out the two silver screws by lining up the holes.
Remove the right hand ball cover with long nosed pliers to unscrew the cover and the internal plastic nut, then turning the vacuum on its back you will need to remove the six screws underneath, four are easily visible in the next picture but two others are quite deeply recessed. The four you can see easily here actually hold a fitting inside the vacuum (see later pic) but for disassembly they need to come out and now is a good time.
Here are the two recessed screws, you will need a star drive allun key for these unless you have a very thin star drive... erm... driver.
There is another hidden screw, it's black and annoyingly a smaller size than all the other screws, very small and again a star drive. It is shown dead centre of the next pic. Also collect that washer on the spindle now before you lose it like I did.
Two more screws, they're at a funny angle for a driver but they weren't difficult.
Now with a bit of persuasion you should be able to remove the assembly and you'll be left looking at the below, difficult to get a good picture of this but the bit the hose is attached to is the bit that the four screws mentioned earlier were holding onto.Reassembly
Firstly before you screw anything together remember you're screwing into plastic so as soon as you feel any genuine resistance stop. Trying to over tighten will strip the plastic straight away, none of the screws need any real pressure to be fully done up.
So, first thing is to attach the hose fitting to the inside of the yoke assembly
After that it is just the reverse of taking it apart, make sure to locate the right hand side 'hinge and spindle' properly as it has lugs to grip the main body. That sentence will make sense when you look at yours.
I hope this is of some help to someone and thanks again to Manchester vacs for hosting this forum, helping me find what was wrong and then sourcing a replacement for me.
