Low clearance bearing puller is recommended for
removal of end cover bearing cone. The bearing puller
pulls against bearing rollers, not against inner cup. It
is designed to prevent bearing cone and cylinder
barrel face from being damaged when bearing is
removed. Low clearance between end cover bearing
and cylinder barrel makes it difficult to use any other
type of bearing puller.

its side. Using 1/4 in hex bit
