Yes. Replace all the hose's. I replaced mine with Stainless Steel wrapped Teflon hose. The shop charges me about $20.00 each. These hoses will last my lifetime and that of my sons.Should we also replace the two hoses at the bottom of the IP at the time that we replace it? If so, is there a source for those two hoses?
Just for smitts and giggles I looked at the TM. Correct FDC only should move when fuel changes and on start up. Now if we go by the TM fuel goes to a pressure regulating valve as per TM that is 20 /21psi. So even at idle where we have a minimum of 30 psi or high idle 60 psi it will not be over 20 / 21 psi in the servo not 60 psi at servo.Now I' even more confused:
The droop screw, which can only rest against the stop plate, and keep the fulcrum lever from moving further towards the ''increase fuel'' position, does two things that are exactly the opposite?:
The pressure inside the FDC only changes when a different fuel is used.
The pressure inside the FDC is the same regardless of engine speed, and does not change during engine operation.
How can the stop plate move during operation? And how would movement of the stop plate cause surging?
This already is my understanding of the droop screw's, and governor's, function. It is, basically, what i learned back when I was an apprentice at M.A.N.
Thanks. I'll see if I can access the manual at work.
I've replaced the injector pump, which means the booster pump has been replaced, and the flame heater died, so it has been removed, but I don't see how it could be a source of fuel entering the crankcase.Beyond, there are 4 ways fuel can make its way into the crankcase. The HH is one of them.
If you replaced the IP completely, you also replaced the booster pump, so you can likely eliminate that as the source. Flame heater, FDC?
