The original pdf file of report KD 320 about the Polycord transmission of the VIRYA-2.8B4 was larger than 2 Mb and therefore it could not be added to my website completely. The data sheet of the Polycord transmission in between the rotor shaft and the vertical shaft was therefore removed. This data sheet has be scanned again but now on a lower resolution of 100 dpi and the report is now small enough to present it completely.
