Searching the web I can't find an answer.
Maybe someone has done this to upgrade the sockets.
My machine (131650000) has the these:
Can newer type replace them ?
Thanks

It looks like the originals grounded on the machine itself. The new sockets have two connectors, one for power and one for ground. If you switch to the plastic bodied ones, you'll have to run another wire for return to ground. If the plastic ones fit in the opening, you will likely be fine.
