Since some of us are stranded without MB manual for 126/617 engines (discontinued),
I am looking into the Bosche Injection Pump manuals offered by Robert Bentley Publishers.

Q - They have several injector pumps manuals, one covering injection pumps type PE and PF,and another for type VE.
There also one "Diesel Fuel Injection" and a fourth title "Diesel Injection - an overview"

Any recommendations ?
Also, any other source for the discontinued 617.951 engine manuals ?

Thanks !
