I've had this one a while, saw it on ebay back in the summer, missed it, and grabbed it on the re-list. SWMBO picked it up, as she was going shopping that day (could have been any day really
)
I remember seeing these everywhere when I was little! They ran for a few years, did a 900w, this one, 1100w, and 1300w I think, in different colours!
The hose came off first, as I had a load of dyson hoses and filters to wash, so bunged this in as well
Typical hitachi tools
It wasnt too bad when I got it, but it was a tad loud
So, on with the usual!
Bag door off
Door catch popped off
Inner seal removed
Pre motor filter wasnt too bad, I think the elderly couple who owned it since new took ok care of it
Handle off
Top cap popped off
Onto the underneath now
Blockage channel removed
Hood unscrewed and removed
Release pedal off
Belt guard off
Very stretched belt and brushroll removed
Brushroll end caps off
and the brushroll was split down
One of the bearings was seized solid, and the other was none too healthy, which explained the awful noise it made. More on that later
2 pivot hinges removed and the base seperates from the main body
Onto the wheels now
Wheels removed, and the brace bar removed, with its orientation refrenced
Height adjuster knob split and removed
There were 2 pictures of the rest of the reclining mechanism being removed, but the flash made them useless so I'll skip that, and move onto removing the baseplate seal
I tried to remove the rear wheels, but failed, and didn't want to damage the, so left them be!
Many screws later, and the main body of the machine splits into 2
Was filthy
Lower cord hook removed
Hose clip removed
Onto the top wiring now
Mains incoming terminal
I see alot of solder sadly around the switch terminals
I had to snip a wire to remove it all
Then realised I'd snipped the wrong wire, so had to snip again
Carrying on, the bag fill indicator piston pops off
The whole motor assembly lifts out now, and this is the suction diverter piece
The bag seal pulls out
as does the bag holding clip
These clogged bits of foam revealed themselves
On to the motor now, it didnt look too clever
Rubber mount off
I decided to see how far the motor comes apart, so fan shroud tapped off
Fan retaining nut off
Fan and inner shroud off
The carbon brushes are removed with just a few screws
Which takes the rest of the wiring with it
All the wires the machine has
4 more screws seperate the motor unit
The coil seems to be fixed, so I didnt persuade it too hard, but the fancase bearing tapped out easily
and, brilliantly, was re-greaseable!
so I did
Coil and armature looked very good
and again, had a servicable bearing
All tickled, I re-assembled the motor unit
All the screws for the whole machine
Everything was the nwashed and dried, including the motor fan and fan cover as it was full of dust, and hair as it turned out once the water flushed it through!
All back together with the clean motor seals
Clean foam bungs were re-fitted
And I then fitted a lick of tape over them for good measure
Cleaned bag seal refitted
Motor was mated back up with the suction diverter, then the whole assembly drops into the chassis
Bag piston reassembled
and refitted
All the wiring was fitted and trunked appropriatly
and crimped up where I cut it
Lower cord hook and hose hook refitted
Bottom section now
Hood seal fitted
Reclining mechanism fitted
Front wheels refitted
Pivot clamps fitted
and the hood and blockage window screwed down. Was waiting for bearings by this point, so left her like this
Bag door clip back on
and the seal pushed into its slot
The pre motor filter cleaned up nicely
and that was that! 2 weeks later, the new bearings arrived (from some country or other), so work re-commenced!
anti vibration shim fitted into the bearing holder
fitted into the brushroll
End caps and axle fitted
New belts
All finally back together
And the old girl is all done! Things got a bit busy with paying Dyson work, so I've been using it upstairs whilst I wait to polish and wax and finish her, so for now, that's it!
