A couple I.D. suggestions
In addition to the "Design 2000" i.d. mentioned above, here are a couple ways to pick-out a Direct Drive from a Belt-Drive:
-- The belt drive washers never had those dual indentations on the sides. They were/are there in DD machines to add some rigidity to the cabinets, which were made of considerably thinnner gauge steel. This was allowed because the cabinet on a DD machine is just there for show basically, whereas the cabinet on a BD is the machine's support structure.
-- Whirlpool belt drives, to my knowledge anyway, always had some sort of lid handle, either metal or plastic.
-- The lids are wider in the DDs, and the cabinets narrower by two inches, at least in the full size machines, so if the lid seems to take up a significant proportion of the top, it's a DD.
I hope those suggestions help. The machine in this photograph is interesting though because it has a console styling which was shared with belt-drives in the 85/86 time frame. Oddly, I recently saw a Whirlpool belt drive that was built in the 10th week of 1987! Must have been one of the very last.
