Overview
A hands-on teardown of the portal assemblies on a Yanmar 1500D, covering removal of both left and right portals, bearing and needle-bearing inspection, actual metric measurements for replacement bearings and seals (with part numbers and links promised in the description), and a broken axle shaft situation requiring a smaller-diameter seal workaround. Reassembly and a brief function check close it out. Most useful for owners already facing portal bearing work on this specific model.
Posted by the YANMARCENTRAL channel, though the creator identifies it as the 'Good Old Boys YouTube channel,' suggesting an owner-operator sharing a real repair job rather than a dealer or manufacturer source.
