Another 1430 Problem

[menchhofer]

Now that I got the neutral switch problem corrected, I have noticed a few days ago the diesel engine sounds different...like it is underpowered.

This has been going on for several days now and I replaced the fuel filter. No change. As I give the engine power, it revs up and then starts a slow down like it is running out of fuel. No matter how much throttle I give it, the engine begins reving down and finally dies. It starts back up again and does the same thing. Because of this behavior, I am unable to use the machine.

I pulled one of the lines off the filter from the fuel pump (at least what I think it is) and turned the key. As the engine idled, fuel did come out of the hose but not a steady stream. Very irregular. So I am now wondering if it is the fuel pump.

Has anyone had this probemo before or can someone offer suggestions I have missed? thanks

Have you checked the air filter, it can certainly restrict power.

Have you checked the fuel tank outlet. Different owners have had problems with obstructions in the fuel tank outlet.

And of course the old fuel cap vent problem is a possibility, if it has one? If it is plugged and not venting, the tank will have a vacuum as the fuel level lowers. Easy to check, just unscrew the cap and try it. Just a thought...maybe not a good one.

Could the strainer in the fuel pump be dirty? I think it is easy to check, just take the one screw off of the fuel pump and see if there's anything in there that shouldn't be.

I will try the strainer on the fuel pump. Did not know it had one. Are you referring to the one screw in the middle of the top of the pump?

I checked for debris in the tank and removed the line from the tank to see if the fuel would run out the hose..it does.

Received the mini hoe and LMB a couple days ago. I think these will be two very useful items.

Yep, it's the one with one screw.
Congrats on the minihoe purchase, it's a great attachment.

Just a thought, but look and see if there is a small inlet screen built into the fuel pump or injection pump. I have seen one of these plug up and cause similar problems. This isn't 1430 specific, just a general observation.

Took screw off the fuel pump and looked as if the small filter screen had some gunk in it. Could not tell for sure as when I removed it, the fuel enlosed in the area rushed out quickly, but here was a small amount of debris retained in the screen.

Anyway, I think it solved the problem. Appreciate the help. I would not have thought of the screen filter in the fuel pump.

Don't mention it. It's always great to help out a fellow TBN'er. /forums/images/graemlins/wink.gif
