question about replacing Yanmar 3gm30f Fuel filter

[Gaute]

Hey all ! Today I started the long dreaded fuel filter replacement, I
postponed it as long as I could but I knew it was time to tackle this.
I started with the primary in a racor 110 (I think thats the model,
all metal casing) and it went really well, got it off replaced and
bled the lines, started the engine and fired up and ran for 10
minutes.

I turned the engien off and wanted to replace the secondary filter on
the yanmar but couldnt figure how to get the filter off ! I had the
shop manual and it said "turn off the ring holding the filter" and
there was no way it was moving. Anyone have a tip how to remove the
secondary filter ? On that side of the boat its incrdibly tight and
specially up inbetween all the othe engine parts in there.

Also I ran the engine for another 30 minutes to make sure I got all
air out so there are no surprises when I go out next time, is that
enough to know there is no air in the system ?

thanks !
Gaute

get a metal chiesel, 1/2 in wide... tap one of the ridges with the chiesel
and a small hammer... it will eventually begin to turn. voila, it's loose
enought for hand turning.

thanks Guy ! I tried with a screwdriver but wasnt sure if that would
do more harm than good, what about putting it back on ? I think the
angle is OK to open it but putting it back on would be harder ?

Just thought of another question, when I do this to secondary, do I
just bleed the "exit" bleedscrew for the secondary filter or both ?

Cold chisel sounds a bit extreme. It may be necessary if it hasn't
been moved for years, but be gentle!

Before you start, turn off the fuel cock at the tank. That way the
Racor and the hoses up to the engine will stay full of fuel.
After you replace the secondary filter on the engine, the ring only
has to be hand tight, as the new rubber ring will seal easily provided
the metal faces are clean.

At this point you can use the hand lever on the fuel lift pump on the
engine to bleed the filter. (Open the cock on the tank again before
starting the bleeding operation.)
You will have to pump for a while to refill the bowl and the new
filter. Some of the filters have two bleed screws. Clear all the air
out of the outer chamber first, then the one in the middle of the
banjo bolt for the output from the filter. Finally the bleed screw on
the injector pump.

Warning. Don't overtighten the bleed screws, because they can break
off quite easily. If they don't seal with moderate torque (eg the
torque you could apply using a screw driver in the head, even if you
are using a 10mm spanner). If that doesn't seal it, replace the
washer.

It is not as hard as it sounds. Just have plenty of rags underneath to
soak up the fuel that will spill.

Good luck.

When was the last time you replaced it? This time last year?

hand tighten, or tap with screwdriver-chiesel.

yes, open bleed screw and hand pump.

[Guy]

of course, use a DULL chiesel.

thats what I was thinking :) ok so the thing will eventually turn off
and its just on good and no special tools required, I have time to
tinker so thats cool... I think I got the bleedig part and found all
points so I think I'm ok, now after doing this if I run the engine for
30 minutes at dock do I know the bleeding was successful ? I know
there are no guarantees againts leaks so thats another story but just
for my own assurance :)

no I didnt do it last year, we had the boat for a little over 2 and
last year a mechanic did everything and I couldnt attend so this year
I'm flying solo... the thing might not be on there THAT bad but I
couldnt hand turn it and using a screwdriver to push on it didnt work,
I didnt try hitting it... so I wanted to make sure there wasn't some
trick to this..

thanks all !

The "chisel" should jar it loose - just remember to tap it in the correct direction (lefty loosey).

When I got replacement filters for my westerbeke they came with noew knurled rings, but they didn't fit so I had to throw them

As a last possible alternate you could split/crack the ring, clean up the threads and put a new one on there - lube it well and unscrew it periodically so it doesn't seize

Advice from the yanmar 2 day class...

They suggest to use a screwdriver only if you want them to come out
and make a service call to replace a cracked ring. Suggestion, use the
back end of the screwdriver to hit the ring , or something that is a
bit more blunt than the blade of a screwdriver or chisel.

Second piece of advice is to fill the new fuel filter with fuel (cup
and filter assembly together) then put it back on. Makes it much
easier to bleed as you don't have to fill the whole cup with the lift
lever.

Third piece of advice if you have the room is to get a cut off milk
jug or detergent bottle to keep under the filter to catch spills or if
it drops, hopefully it gets caught in this. (This works great for oil
filter as well).

Gaute,

There are special strp wrenches available from any auto parts store that
will do the job vey easily without the risk of penetrating the shell of the
filter and getting diesel all over the place. One addition trick is to put a
plastic bag over the filter to catch any minor leakage.

[Guy]

running for 1 minute is enough to tell... plaus check for leaks

[glu...@comcast.net]

I went to Sears and bought a strap wrench.  Works good and I don't have to take a hammer or chisel to my engine.

[Gaute]

Hey All, I got the strap wrench too but couldnt get it to fit in
there, the fuel line to the pump was in the way. I ended up using this
woodscraping tool which is wide and square at the tip and fit perfect
on the ring, one slight tap and it moved enough to turn it by hand...
this was actaully complicated by a clamp piece from the primer that
was sticking into the ring making it stuck as well... got the thing
off, replaced filter and gasket and put diesel back in, pumped a few
times and done... have a leak on the ring the first time I fired up
but after using the tool one tap it sealed up nicely, re bled it and
fired up again, no leak.


thank you all for great ideas, keeping it in a ziploc was a great
idea !
