Re: Yanmar 2GM 20 breather hose!


 

¿ªÔÆÌåÓý

I changed both primary and secondary filters and bled the system at secondary pump. Engine starts up and idles well but there is very small amount on acceleration forward or reverse. Engine worked really well after I drained the crankcase and installed new lift pump and motors up river 2 hours at 2000 rpms. I¡¯ve been starting the engine everyday since and watching the oil but hard to see new oil on the stick.?

I didn't catch earlier if you had a fuel filter hooked up. Regardless,
does fuel come out when you disconnect the fuel line and stick it in a
clean, salvaged glass jar, then turn the ignition on (don't have to
crank it over, just "acc"/on)? No fuel, suspect the filter first.

Assuming the filter is fine, if you can't prime the diesel with a hand
pump or the pump is making clicking noises but no fuel comes out,
stick a stick in the tank and see if you can scrape gunk off the
bottom. That's a big clue.

If no fuel is coming through, can you pump some clean diesel backwards
with a hand held fuel primer? If so, does fuel flow into the jar for
a moment afterward? Gravity feed should do the trick.

Clogged injectors are a possibility, but that was fine a bit ago.
Maybe one was clogged and you didn't notice but I rate that as less
likely. Suspect simpler problems first. And if they are clogged, I
have questions about the fuel filter and fuel tank so those should be
checked first anyway.

Does the fuel filter separate water? If not, get one that goes. You
need to know if there's water in the fuel, before you try to burn it.
It happens a lot and it's easy to deal with (drain it off the bottom
of the separating filter) but it's bad if you don't deal with it.

How's the oil now? And the oil quantity?

When you bleed the system, does fuel come out at the injector pump?
It's possible that you bled the system before but didn't get all of
the air out of the injection lines or pump.

If you don't have a water separating filter, stick the fuel line into
your green diesel jug and get the air out of the line or bleed it
again (I keep a generic 12 v small diesel engine fuel pump wired to
plug into a cigarette lighter style plug for testing and priming
lines) and try that. You'll have to turn it over for a bit (crank 10
seconds, wait 20, repeat several times) to pull the fresh fuel in.

(okay, more emails coming in while I write this, but it still may be
handy for a procedure for trouble shooting fuel problems... and your
service manual should have trouble shooting procedures too!)
