Managed to get the temperature in the garage up to 10 C today, which is like summer compared to the -9 C (windchill -16 C) outside, thanks to a very good and inexpensive small radiant heater sold by Lee Valley. And so, off came the front hubs, for an inspection of the hubs and their inner and out bearings.
View of the inner end of the hub, with the oil seal over the bearing, which can just be seen underneath. Some small corrosion on the seal.
A view of the outer bearing, looking shiny and brand new.
The inner race of the bearing. The brown is just the coating of oil (the little there was left - I'm not sure it had been filled often in its lifetime). The rollers look in good shape, and all moves smoothly, so I'm hoping all is well. All four of the inner and outer bearings of both front hubs look like this. I can't see anything wrong, but will ask the experts to be sure.
Another view, not looking conical due to the camera lens....
A murky view of the inner race. No scarring or scratching, and so here again I am hoping all is well. The inner bearings weren't removed, as if they are in good condition there's no point in damaging the seals, etc..
