A rough translation "VDT-WPP 711/11 4.63 Test instruction for petrol injection pump with mechanical metering unit "
This doc was written before the advent of the Porsche style double row PED pump, (note document date April 1963) but it covers the PES6KL (MB & 906E) PES8KL (MB & AM V8) and the EP/RLA regulator used by both versions (including the Porsche style PED)
Note that it refers specifically to the Mercedes Benz water cooled thermostat as opposed to the Porsche hot air thermostat (a later evolution - no doubt covered in VDT-WPP 711/11B.
It covers the tools required, calibrating the pump on a pump dyno according to the (seperate) test spec for each pump model, right through to sealing the appropriate screws with yellow paint and a lead seal.
Looking forward to getting Bosch's latest version of this doc (VDT-WPP 711/11B)
