<VV> Blower bearing lube

[Larry Forman]

Hi Craig,
You gave a good description.  I would caution to use just enough to have 
the bearing rotate slowly and then STOP lubing.  As an experiment, I would 
lube until it got stiff.  Then lubed more and rotated until loose and 
continued until I blew out the lower seal.  Don't do that.  The lubing tool 
works fine, but the cavity is quite small and you should lube a couple of 
strokes and then check rotation until it gets sticky then stop.

As for lubing the rear EM axle bearings, I would NOT follow Richard Finch's 
approach, but use the excellent procedure Larry Claypool has in CORSA's 
Tech Guide.  The complete process is quite well documented with pictures 
and text.  Required reading for doing this process.  Doing this his way and 
yours enables you to check the inner rollers for pitting and possibly 
replace some of them.   Unfortunately the outer rollers are inaccessible 
and have more stresses on them.  But for both sets of bearings, lubing 
frequently and before they make noise is the right approach.  If you wait 
until they tell you that you should have lubed them earlier, you are too late.
