[R-390] Lubrication of KC and MC Bushings

[Barry Scott]

I found that lubrication figure.  It is Figure 89 on page 114 of the TM
11-856 manual.  It does not mention lubricating the KC or MC shafts so now
I'm not sure if I should.  I wouldn't think a few small drops of synthetic
oil would hurt there.

Thanks,
