Hi All,
Crummy weather day here in NJ so I decided to tackle one of my more recent garage sale finds. I found the following machine for $5 complete with powerhead (no pics of that yet). With a new bo-jack bag in place and nothing else, it pulled 82" on my guage. This is one powerful old electrolux. But since I'm and engineer, and as the saying goes we are good at "Fix it 'til its broke" I totally ripped it apart and just finshed a couple hours of scrubbing. It must have been maintained as there were several "service" stickers on the machine and functionally it ran well.
I plan on replacing the carbon brushes, and the brushroll and belt in the power nozzle. Other than that, it does not look like any parts will be required. When I took the carbon brushes out, one was cracked in half, but the pieces were perfectly mated to each other in the holder so I don't think this would have caused any problems.
Now for my questions. First, did this model, was this model supposed to, have any type of filters other than the bag. When I took this one apart, it did not. There was carbon brush carbon dust all over the inside of the unit and around the diffuse air exit ports around the top and in and around the "blower door". I can not believe there was not supposed to be something, some wadding, foam, felt, something to try and catch that. I also wonder if there was supposed to have been any type of secondary filter to protect the motor. If anyone knows either of these, please let me know.
My other line of questioning relates to the "automatic" function. All the tygon tubing lines appeared to be in place and not too stiff or clogged. As long as I have it so far apart, I will replace all of it, I just need to nab some from the lab at work. The diaphram that accutates the door release is supple and does not leak. Aside from replacing the tubing, what should I do to ensure this will work? Are there any O-rings within the adjustment mechinism that need to be lubricated to enusre a tight seal so that it may acctuate the release by pulling a vacuum on that diaprham? Also, I removed and dissasembled the check bag light since it did not light. Picture below. I used my multi-meter to check it out. The resistor in place ohms out ok. The bulb however, does not, there is no continuity from one side of the bulb to the other. You can see in the one pic that inside the bulb there are two what I will call "rods". Inspection under a 10x loop reveals that they are not connected, I however see no remains of a fillament in the bulb. I'm sure it had to have one at one point, I will look at an electronics store to see if I can find a replacement bulb. Has anyone else encounterd this, and how did you solve the problem?
To summarize, I need to know:
1) Filters?
2) Anything other than replace tubing?
3) Light bulb?
Thanks in advance for all of your expertise and advice. Now, here are the pic.
