Morning all, I have replaced the entire valve chest on my 03 digger and most of the functions have improved. However the new chest has the PRV for P1 relocated onto the left hand side where a pipe went to the straight ahead valve. The RH drive lacked power when I bought the machine but a new motor did not improve it. Operating the boom while travelling slows the machine dramatically which the straight ahead valve is supposed to prevent by using P3 to compensate, according to the workshop manual. Does anyone know what goes where on this valve?
