Replacing the fuel filter

[dlabrie]

I need to replace the fuel filter in my B2910. It looks pretty simple, unscrew the bowl, replace filter, screw on bowl. However, I am sure there must be more than that. Do I need to empty the tank or clamp the fuel line? Will I have to bleed the system afterwards? Any hints would be appreciated.

Thanks,

Dlabrie:
I'm not a bota person but there should be a fuel cut-off lever close to your fuel filter, mine on my Yanmar is right on top of the mount that you screw and unscrew the fuel filter bowl. and make sure you don't tip the little spring in the bottom of the bowl when replacing the filter

Very simple, but have a clamp handy just in case. My cutout didn't work, and when I posted that issue there were several "Me too" responses. I also washed out the bowl with kero. Not sure about the 2910, but I had to bleed my L3010 afterwards. Nothing to it; your owner's manual describes the procedure very well.

If you don't have a fuel shutoff valve you will need to plug or clamp the line. After replacing the filter if you either refill the sediment bowl with fuel or leave it loose until it refills, you should not have to bleed the lines.

The little fuel shut off lever worked just fine on both my B7100 and B2710 (both used the same fuel filter). There was a bleeding procedure for the B7100, but it was not necessary on the B2710. And you don't actually unscrew the bowl; instead of turning the bowl, you turn the collar or ring (for lack of a better word) at the top of the bowl. Have a pan or bucket under it because you'll undoubtedly spill at least a little fuel. The o-ring type gasket is reusable; just don't lose it (it'll very likely stay in place anyway).

HI,

I think there is a note in the operators manual for the B2910 that the fuel tank must be almost empty to ensure that nothing will leak out when the filter is removed. Something about a return line or something... I don't have the manual handy.

It might say the tank must be less than 1/3 full, or something like that...

That may be right, Bill, but I thought it was the same as the B2710 and I could change mine with a full fuel tank with no leakage.

Bird,

I only know what my manual says, as I have not changed mine yet. Or better said, I only know what I think I remember reading in the manual /w3tcompact/icons/laugh.gif.

I do remember that the mechanic told me that the older models had a shut off valve, but the newer ones don't have a seperate shut off, and that when the fuel bowl is taken off the fuel flow should stop...

Guess I will find out when I get to the fuel filter change point. At the moment the tractor is only starting into its forth month and 127th hour! /w3tcompact/icons/grin.gif

The manual for my B7500 says that the fuel tank needs to be 1/2 full or less. When I did my 50 hour I slowly unscrewed the filter and fuel began to go everywhere so I screwed it back on. Realizing that I had to change it I just unscrewed it as quick as I could the next time and low and behold the fuel flow stops once the filter is removed completely. I have no idea how it does this but it does. First time fluid changes can sure create a mess until you figure out a good procedure. I just hope I don't forget it all for the next service interval!/w3tcompact/icons/smile.gif

Thanks everyone for the info. I guess I'll look for a shut off, If there isn't one, I'll wait until the tank is half full and give it a shot. I'll let you know what happens when i do it.

Neither do I, but being the curious type, I think I'd have to look at a parts manual and see./w3tcompact/icons/laugh.gif Speculation, of course, but sounds like a float type check valve to let fuel through slowly, but not quickly.

It depends what the model number of your B2910 is, I think. I know the early B2710's and B2910's had a fuel shut-off. The later models, of which mine is, somehow do it automatically if the tank is less than 1/2 full. No bleeding required./w3tcompact/icons/smile.gif

Now the bad news. ...

My dealer had originally sold me the filter for the earlier series which assumes a shut-off valve. I forgot the exact price, but I think it was just a couple of bucks.

When I went to change mine, I realized they were different, so I put my old one back on. Next trip to the dealer, I picked up the correct filter....and needed to leave an extra $10 or so! /w3tcompact/icons/sad.gif

Convenience doth have its price!

Some 0f the newer diesels DO NOT have shut off valves..reason being that the majority of the compacts sold were being sold to 1st time users.To many problems with engine being ran while fuel was shut off.roostermaster..bosh type systems then would have to be manually bled.I believe they did incorperate a gravity float shutoff.If you have a rubber inlet hose to your filter you can gently close it with a pair of visegrips.No you should not have to bleed your system.Don`t know how many times i`ve forgotten to open the fuel valve on the old Harley...lol Hope i helped a little ...Sid

Rick,
When I did my 50hr service, I bought all the parts and had a mechanic/friend help me. Before we took apart the fuel filter we noticed that there was no way the new one would fit. So It didn't get replaced. I went back to the dealer and the same thing happened to me. The new filter cost about twice the first. The tractor is at 170 hrs now and I figure I had better change the filter.

Jeff;

In the top of the housing that the fuel filter screws into is some sort of spring-action fuel release. When the bowl is off, the spring device closes the fuel line and stops the fuel. As you probably discovered, when you start to screw the filter bowl back on, fuel starts to flow again, so you have to screw it in pretty quick.

I had to drain my fuel tank once (accidently put gas in it) and the only way to drain it was to pull the fuel filter bowl off, stick a wide aluminum baking pan underneath to catch the fuel, and the use my finger to push up on this spring device to let the fuel leak out. Took about two hours; not too fun.

I also did not realize that there had been an o ring on top of the filter, so I had a problem with it leaking after I put it all back together. Took awhile for me to figure that one out.

DOH......2 1/2 hours!!!!! Sounds like and excellent excuse to buy one of those handy pumps./w3tcompact/icons/smile.gif Thanks for the explanation. I do wish that the manual was more detailed in areas like this.
