84 Bosch pump, adjustment issues
Not sure if this is the correct placement, but after all my googling, I determined my pump closely mimics the 12-valve pump.
I have an 84 Volvo F613 cab-over style box-truck with a TD60B engine with 178000 original miles. When I first got it, the fuel filter was clogged to hell and barely ran. Replaced that and actually got some power out of it.
Next thing's next, raising the max-fuel setting:
I read around and it says to rotate the shaft attached to the AFC diaphragm to the side that has the more aggressive angle to it, but I cant for the life of me get the diaphragm out of the housing =/, no biggie, ill just adjust the star wheel "not sure what it does yet"
I cranked the star wheel 13 clicks clockwise and took it for a spin... I didnt really notice much of a difference, maybe a little, but not enough to really register on my pants-dyno.
Any ideas? should I keep cranking?
Here are the fuel system specs from the manual:
Injection Pump: Bosch PES 6 MW 100/320 RS 1004 Z
setting: 19' B.T.D.C.
feed pressure: 14-21 PSI
Governor: Bosch R V 300-1400 MW 6
Injectors, nozzle holders: Bosch KBEL 95 P 9/4
Nozzles: Bosch DLLA 150 P 22
Opening Pressure: 3900 PSI
Thanks in advance to anyone that can point me in the right direction.
Here are some reference pics of what the pump looks like.
