(ET) greasing bearings

[Neil Dennis <wombat RealNS com>]

I usually grease sealed bearing by using a small needle hypo (shringe)
and injecting like lithium grease by sliding the deedle between the edge
of the seal and bearing ring.   Sometimes if the grease in the bearing
seems to be dry a little wd-40 allowed to soak in around the seal helps
also.

If you are good at it and lucky, you can remove the outer seal
carefully, then clean and regrease but that is a chancy operation.
