My Elliott 921 surface grinder still does a very reasonable job; not perfect but plenty good enough for the majority of work.
Trouble is the spindle bearings sound 'dry'; the manual says regrease every 18 months but don't tell you how. Looks like you would have to tear down the whole spindle to do it.
Machine is probably 30+ years old and my guess is the bearings have probably never been regreased.
I cannot detect any amount of play in any direction either axial or radial and the spindle runs freely and smoothly except for the dry noise.
It has a pair of angular contact bearings at either end of the spindle.
Would regreasing prolong the life of the spindle and would dismantling be in danger of damaging the bearings?
Shall I just leave well enough alone?
Regards,
Mike.
