    I have a four year old box fan that occasionally needs to be
    "hand-started" to get going. It takes a couple of flips, like hand
    starting a propeller.

    I'd like to disassemble and degrease the fan and motor and re-assemble.

    There has to be millions of this kind of fan out there. It's the type
    with a 3 speed plus off rotary switch.

    Can the fan & motor assembly be disassembled enough to clean and re-grease it?

    Thanks.

    I had the same problem. 3 or 4 years ago I took the grills off of
    mine. I cleaned all the disgusting dust and grime off, first with a
    vacuum cleaner then I used a rag dampened with windex. I was careful
    not to let any liquid go into the guts of the thing. After it was
    cleaned up I saw 3 small holes on either side of the motor in close to
    the shaft. I took some 10-30 motor oil and applied just a few drops to
    each hole as I manually turned the fan with my hand. It felt better
    right away. I didn't want to spray oil all over the house so first I
    let it sit for a few hours on ether side with a rag to catch the
    little bit of oil that dripped out. Then I took it out in the drive
    way and ran it for about 15 minutes on high. I didn't notice anything
    coming out of it and it's worked great ever since.

    Those things are permanently lubricated the factory but what the hell you
    can give it a try :)

  4. You need Oilite type oil.

    I never heard of Oilite, so i googled it. It's an oil-filled bushing. I
    still have no idea what "Oilite type oil" is.

    Any suggestions as to dis-assembly or cleaning the bushing?

  6. You need a solvent to clean the bearings. There is a special oil for porous
    bronze bearings (Oilite type oil).

    Disassembly - you are on your own!

    I've had good luck with Marvel Mystery Oil, you can probably get by with
    any light machine oil though, it's just a fan, nobody will die if the
    bushings seize again.
     
  8. True, but if the bearings develop a slight slop the speed goes way down.

    I've used Singer sewing machine oil over the years on fans just like this.
    The fans are nearly identical, the brand changes over the years. I think
    the last brand name was Lakewood.
     
  10. Why don't you just buy a new one. Why spend all day dicking around
    with a fan only werth twenty dollars.
     
  11. Hi!
    Is there ever an instance where that isn't a total joke?

    I've seen lots of fans that were intended to be oiled periodically and never
    were, but ran for years (sometimes a decade or three) before needing
    attention.

    As for so-called "permanently lubricated" fans (and other devices) I have
    lost count of the ones that I've had to oil because they seized up or got to
    be very noisy. Computer fans, regular fans, exhaust fans, etc...

    ....this says volumes about the quality control of then and now.
    Why? (I realize that I may regret asking, but there you go.)
    What are these?

    There are two models. The cheap model needs to have its bearings
    cleaned and lubed periodically. The OP, on the other hand, claims he
    bought the expensive "premium model" (two or three times the price)
    which advertises that its bearings are "lubricated for life." Hence his
    question about how to proceed.

    Bronze bearings permeated with lubricant is the theory I guess.
    No doubt but just as many that have oil ports that are neglected fail.
    I guess I was replying to the context of cheap fractional horsepower
    motors designed to throw away after a couple years. I don't see a use in
    re lubricating a motor that doesn't have a reservoir to hold additional
    oil.
    From a kook list, not nominated by peers.
    Troll award and Cabal Order Obsidian number awarded to those who
    have been threatened the most on Usenet with harm or death. Color me a bad
    boy as it may seem but it's again based on Usenet kooks.

  14. Probably found in the same list as so-called No Maintenance car batteries.

  15. Hi!
    Funny...I actually *did* pry the top off of a Delco Freedom maintenance free
    battery to add some water when some of the cells appeared to be low. It was
    a trick to get it back on, but I proved to myself that it could be done.
