Was using the getting-ancient Honda Harmony today and putting up with the intermittant "running-out-of-gas" thing it does ... but I also thought I heard the wheels squeaking a little as I puttered along.
Never having ever done anything with the wheels/axles, I figured taking them off and giving them oil/grease/whatever might be in order.
Well, the front wheels came off easily, but I was pretty surprised at what I found. Each wheel had an inner and outer
roller bearing. I couldn't believe it. Is this over-engineeing or what? I expect to see the wheels turning on a teflon or some other material bushing ... not a pair of roller bearings.
Anyway, the bearings barely moved. The axles were in good shape. Definitely used-looking but no heavy scoring. I suppose after 15+ years, this was to be expected. I popped all 4 of them out (rear was a different design because it's self-propelled) and dunked them into some cutting/penetrating oil.
The oil turned from a medium-dark brown to dark grey ... almost black ... in a couple hours. I guess that's the oil and solvents dissolving all the grease ... even the hardened stuff.
Aftre 2-3 hours, I pulled them out of that nearly-black soup and tossed them in a jar filled with a few ounces of ATF and about a half ounce of Neutra. Soaking them like this for a couple days should clean them up nicely. At the time of the switch, they all turned but still had too much "grit" to them.
Once clean, I will have to re-lubricate them properly before re-installing. How to do that?
Method #1 - Soak them in gear oil (75W140) and put them back on.
Method #2 - Attempt to re-pack them in some type of wheel bearing grease before re-installing. I have Schaeffer #238 on hand. I'm just afraid that I won't be able to actually force the grease into these small units which are probably not designed to be re-packed.

PS - This thing doesn't usually smoke at all at start-up. I've been watching it since this thread was created. It only does it at certain times ... like after the thing has been sitting for a long period of time (months) or perhaps after the machine was tipped.
