Dayco Products, LLC located in Hillsdale MI is an industrial rubber molder specializing in crankshaft dampeners for automotive engines. In October of 1986 Dayco purchased a customized PDI walkie stacker, serial number 319,717, from Big Joe Forklifts to load molds into rubber presses for eight production cells. After 33 years of daily use the PDI had reached the end of its service life, prompting Dayco to search for a replacement. Although Big Joe had discontinued the PDI line, it was able to match the custom specs on the PDX20 platform, build the truck in their Wisconsin factory and deliver it in just 8 weeks.
