No it doesn't. The volume of water increases by just under 10% as it freezes. At no point is the density of liquid water equal to that of ice. Liquid water's volume is largest at 100 C. Water is most dense at 4 C Density of ice at 0 C: 0.917 g/ml Density of water at 0 C: 0.999 g/ml Density of water at 4 C; 1.00 g/ml Density of water at 100 C: 0.958 g/ml Density of water vapor at 1atm: ~0.00081 g/ml Mark

I put it back together today (some new pictures in swing arm album), which went OK considering laying on cement in 20-something degree weather. I pre-wetted the bearings with WD-40, exercised them before installing. Then came the problems. I had to re-orient some of the fittings so I had a clear shot at the fitting with a grease gunn. I used either washers or gasket material to make those adjustments. The second problem was either the Chinese grease gun or the Chinese grease fittings but the Chinese grease seemed OK. Once snapped on, I could not disconnect to grease gun - pulled, pried, hit - nothing worked. Luckily, my first attempt was on an angled fitting, which is a two-piece affair, so I could unscrew the second-stage off of the base fitting and then sit on a stool and pry it out of the grease gun's nozzle. The nozzle isn't like a vice anymore but it is still a tug-o-war to remove it from the fitting. Once pressurized, the moly grease first pushed out a mixture of WD-40 and grease and then all grease. I think that the WD-40 will help get grease to all areas of what essentually started out as a dry needle bearing. I'll put the back wheel back on tomorrow (have to go back to work too) and then switch back to the engine assembly - my Christmas present to myself. Don R100, A6F

What a slimy dirty rotten mess getting 3.5 yrs worth of crud off of the chain guard and slider areas. I used a large kitty litter bucket with 2 gals of oil partswasher fluid. Plan to mix that in with my waste oil for a friend's garage heater. > > > > Removing the pivot bolt was a bit tense, as you can see it was rusty in the middle and held fast to the sleeve through the pivot lever. I'm not sure there is a long term cure for the rust, since greasing it will allow the bearing's inner sleeve to rotate around the bolt rather than having the surrounding needle bearings rotate around the sleeve, as designed. > > > > I now have to re-read the 'watt-man' files on Zerk installation.

All stock ring gaps were well within spec after 22.6K, so I'll keep it stock. > > > > Don R100, A6F > > >
