The worm on the new replacement looks to be a larger diameter, is this just an illusion of the photograph? If both the worm and the worm gear are brass, that would explain why they failed so early. For better wear characteristics, the worm should be steel with a brass worm gear. Just another example of cheapening the product through poor engineering practice at the expense of product longevity. Might want to get a spare set of parts while they are still available...
