Author Topic: DC05 reassembly after fitting new motor (Read 11139 times)

[This is really a continuation of the "elbow removal" post https://manchestervacs.co.uk/DysonForum/index.php/topic,1588.0.html but I've started a new topic to make it clearer what this is about.]

The new motor and filters arrived yesterday (thanks, ManchesterVacs) and I have started to reassemble the DC05.

BUT ... I'm stuck. I've got the motor into its housing, snapped the lid on and seated it into the lower chassis. Then the Dyson Medic instructions say simply: The upper chassis needs to hook over the round part and gently lower into position. Unfortunately it's not quite as easy as that. I didn't have to remove the wheels to remove the motor; now they are very much in the way. I've tried to remove them - they are one piece with four tabs which push through the smallish hole in the centre of the lower chassis - but failed. I cannot squeeze all four tabs together simultaneously.

Is there a way of wriggling the two halves of the chassis together without removing the wheels?

I think the wheels snap off with a good tug/lever from behind with a screwdriver. The few DC05's I've had apart need the wheels off to make it easier

I'd wait for someone who has had more than 3 apart to confirm or deny my response though, dont want you to break your machine!

Thanks Beko.

Any advice, Mvacs?

There are 2 different types of wheel fittings on the DC05, follow this link to see both of them.

Sounds right to me.

Madrat, the link you referred me to is the one I have been following throughout. My DC05 wheels don't have the plastic insert, but I need to remove them in order to put the two halves of the chassis together. The Dyson Medic site doesn't say how to do this.

Is it possible to get the chassis together without removing the wheels?

Thanks for all help offered ...

If you don't have the inserts then you just pull the wheels off. Probable could do it with the wheel still on but you would need 3 hands and even then it would be very fiddly.

I've just looked at a dc08 in the shed and yes, I think the wheels just snap off. Insert a screwdriver inside one of them and pull it towards you, should bring the wheel with it. I've never had a dc05 with the wheel insert tbh

No, I've never seen one with inserts.

Woo hoo!!! I've done it! I managed to get the easier wheel off - the one opposite the cable drum - by jamming a screwdriver in and squeezing as many tabs together as I could, and easing it out. I removed the cable drum and tried to get the other wheel off, but the extra bit of housing got in the way of my pliers and I couldn't squeeze the tabs together.

Anyway, with the one wheel removed, I reckoned that I would be able to get the two halves of chassis together. It was still too fiddly with trying to hook the upper part over the round thing, so I found it was easy to remove the semicircular piece which is part of the hose fixing. It is just three easy tabs. Then I didn't have to hook anything over anything else, just wriggle the upper chassis past the wheel over the cable drum.

I was very pleased when it finally snapped into place! Then it was a case of gingerly lowering the Torx screws into position and tightening - hooray for magnetic screwdriver!

The rest of the reassembly was a doddle (although both my wife and I had thought that both green buttons faced the same way - they don't!) and it all works once more.

With the new motor and two new filters it smells a bit, but I'm hoping that it's just the "newness" working its way through.

It also seems louder than before. Is the motor more powerful than the original? Or is it that the old, clogged, HEPA filter served to deaden the noise?

Now I'm a happy bunny, and my wife has got down to vacuuming straight away!

Beer time to celebrate.

New filters deaden the sound less! Plus the new motor will have new bearings, so will spin faster in theory! New filters do smell a bit, and the motor may smell slightly as it beds the carbons in and distributes the grease in the bearings.

Glad you got it sorted! Well done, the cylinder ones aren't as easy IMO to take apart!

Presume your having a well deserved beer or 3 now?

Don't know about the Mvac motors but every replacement I've seen is 1600w as opposed to the original 1400w

beko1987 · « **Reply #12 on:** January 14, 2015, 08:42:37 pm »

Ah that would explain it too! If its 1600w get a turbo brush, would spin that up much better too!

The beer is slipping down nicely.

I haven't tried the turbo brush - it seemed very stiff when I tried to turn the bristles. I always use the crevice tool for everything - carpets included - I like the concentrated suction.
