How do I reassemble this Quando rear hub?
How good does this have to be?
If you are going to use this as daily transportation to work I'd want the correct dust seals and I'd go with a different wheel.
If this is a klunker you don't really care about I think you can experiment and arrive at a workable assembly.

Here's my best guess at something workable.
Parts "F" and "E" look like dust guards. Sometimes they press fit into the hub AFTER the bearings are greased into the races.Sometimes, like in the picture you linked, they are attached to the cone. They usually match so I'm not sure what to make of the rubber seal. See if it will press into the hub on one side or the other.

With the bearings in and the dust covers on (assuming they fit into the hub)
And, with the freewheel off - if possible.


Thread the thin cone "D" about 1.5 inches down the axle.
Thread locknut "B" after the cone until it hits the cone
Tighten the locknut against the cone but only snug - not tight, you'll probably have to move it later.
Insert your axle assembly into the non-freewheel side
Thread the fat cone onto the freewheel side of the assembly until it just touches the bearings.
Slide the spacer "H" onto the freewheel side
Thread the other locknut "B" onto the freewheel side
Play with the left over washer "G" and see which side it works on. My guess is that it will go on the freewheel side. I'd put it between a lock nut and the spacer if it helps spacing on the freewheel side. If it helps the spacing on the non-freewheel side I'd put it between the cone and the lock nut.


Now you play with the spacing so that the wheel is spaced in the frame, the freewheel spins and the chain has enough room on the smallest freewheel gear to clear the frame and the axle sticks out about the same amount on each side.
