MK-17 USSR Vintage Model Engine Diesel Second Hand (Box 109)

Mk 17 case is die cast aluminium with a lightly blasted finish. Mold flashings on the centerline die joins and the exhaust area top have been rather crudly dressed apparently against a rather coarse grinding wheel, although the blasting tends to hide this. A serial number is stamped into the end of the right mounting lug (viewed from the rear); while a prominent "MK-17" appears in raised lettering, cast into the left side of the main shaft journal.  this is a twin ball race design.
