This what we use. (Attachment Link) Not standard WD40.
Aldi have cans of lithium spray grease apparently, I keep meaning to go get some. I just use boggo car grease on bearings
Exactly, by the time you have scraped out 15 years of dry old grease, got the thing turning again, filled it full of grease and refitted it so it's quieter it'll be fine. It's a hoover brushroll, not a car's wheel bearing! Also, there isn't much point oiling motor bearings on dysons, as their sealed bearings, so the oil goes nowhere near where it is supposed to 97% of the time. Either replace the bearings (608Z's I think) or replace the motor! Again, I've never had any issue with greasing brushroll bearings, and I do every machine I get as it quietens them down!From what I read on vacuumland ages ago, grease your balls, oil your sleeves. So a sleeve bearing, the kind Hoover used in Junior motors, where the bearing is a brass sleeve around the shaft, oil works well (although again, I've used a thin smear of grease before!). Ball bearing bearings, oil, as it holds the balls in suspension (or similar) plus doesn't fling straight out when you fire it up.I rarely use normal WD40 for much more than sticker removal nowadays. I have a can of spray grease which I rarely use, a can of 3-in-1 oil which gets dripped into non replaceable bearings to shut them up (lux 500 etc), tin of normal motor grease for brushroll bearings, then plusgas and coppaslip for the car. Seems to do well enough. I do want to get some white lithium grease though, for helping plastic moving parts glide a bit better.Apparently for really old stuff, sewing machine oil is the thing to use, but I don't have any of that, and my 1930's Hoover 825 was quite happy with 3 in 1 (not turned it on in 4 years, will see what it's like when I ever get round to finding all the bits and rebuilding it!So yes, Grease your Balls, Oil your Sleeves. Save WD40 for waterproofing electrics, removing stickers and buffing up cyclone bins!
Oooh didnt see a link, I'll have a lookYour right about it lasting forever though, I've had my tin of grease for 3 years and it's just over half used! I don't fully agree with the brushroll bearings sounding louder after a greasing, when I've had machines back a few years later for a snapped belt/other issue they've always sounded fine to me (although I find DC07 Origins have a funny roar to them even with a brand new brushroll and belt).I found the original thread I read years ago - http://www.vacuumland.org/cgi-bin/TD/TD-VIEWTHREAD.cgi?11638
The oil in your link says use in bushing type bearings, which I think is the fancy word used to describe sleeve bearings. Plus the sleeve bearings it will refer to in R/C cars will be tiny I imagine. It'll probably be fine though, and may be slightly handy for motor bearings as it could be thin enough to seep into it. But then will it soften up the dried up old grease in there? If not, then it's kind of pointless, plus is it thick enough to not just run out?I remembered why I don't use my spray grease, it stinks! I lubed the bearing on a turbopower 2 once and it stank! Worked well on the height corrector on the Xantia though IIRC
