Oil & Fuel Does this sound like gelled fuel?

[mfreund]

When mine did that it must had had water in the fuel. After changing the filter,adding 911 to the already power serve treated fuel. I found the metal 90 degree fitting where fuel comes out of the tank had a ice chunk. I tried to drain the fuel out of the tractor and none would come out. Be very careful about applying heat as my tank was plastic and fuel lines were rubber. Hit it for 2 seconde and try to start it. When it dies hit it again for 2 sec and try to restart. keep doing until it cleans up and runs.

Yep, I had water/ice problems with my F935...ever since then I make a habit of running a small dose of Power Service 911 in the fall before freezing weather. Regular power service is a great anti-gel, but it doesnt remove water.

Back on topic....while it could be parrafin in your filter (I change fuel filters every 100 hrs) one thing it COULD be is algae in the fuel.... Cure is the same...treat fuel, change filter, clean strainer.....if it is Algae, buy 2/3 filters as you'll need em ....

I know what the problem is. We fixed a 5205 two weeks ago exhibiting the same symptoms. Turns out, poor design by Deere. You have a little water in your fuel. It is freezing in your return line. This creates back pressure on the injection pump. The tractor will start and run a few seconds until the pressure from the return line won't let the pump function properly anymore.

Relocate the return fuel line to the top of the tank.
Here are instructions and a list of parts you will need:

Check your serial number, but I'll bet it falls in this range. All part numbers are Deere numbers.
===========
===========
Model 5105 and 5205 Utility Tractor with the following PIN range.

LV5105B (110001-210593)

LV5205B (120001-220624)

Complaint or Symptom:

The engine will not start or stalls when the temperature is below freezing (32ｺ F or 0ｺ C).

Problem or Situation:


The fuel return line is at the lowest point of the fuel tank.
Water trapped in the tank will freeze and block the fuel return line.
Solution:

SIB: 01-3-20-1 provides an instruction and photos to re-route the fuel return line as follows:

Route the return line to the top of the fuel tank and add an elbow fitting.


Drain fuel from tank.

Cut the return line at bottom of tank 76mm (3.00 In) long.

Plug end of hose remaining on tank with an R128357 headed pin and AR48236 screw clamp.

Drill 13mm (17/32 In) hole in the top of fuel tank at the location shown in the SIB.
NOTE: Do not allow plastic chips to fall inside the tank.


Install M66005 rubber grommet into drilled hole.

Add grease to large end of R119551 elbow and press into ID of grommet until body of elbow is resting on grommet.

Remove the remaining fuel return hose and replace it with a new 2950mm (116 In) long TY22551 Fuel Return Hose.

The routing and banding of the new hose should follow the old hose from the engine to the fuel tank.

Install return hose onto tube at the rear of the engine and clamp with AR48236 screw clamp at each end.

Route the return hose up from the bottom of tank between the rear of the ROPS and the fuel tank.

Install return hose onto elbow in tank and secure with AR48236 Screw Clamp.
Parts:

2 - AR48236 Screw clamps

1 - R128357 Headed pin

1 - R119551 Elbow

1 - TY22551 Hose

1 - M66005 Grommet



Additional Information:

The revised fuel return hose routing has been incorporated on tractors after the PIN listed above.

Great to know, makes perfect sense......BUT if I had an affected machine I wouldnt be performing this fix...IMO its just a band aid...not the cure.
The true FIX for the issue is keeping water out of your fuel...regardless of return location, tractor brand, tube size, etc... you should NOT have water in your fuel. Water in the fuel could lead to many more expensive problems (smoked fuel pumps, etc)...

Some one say paraffin...

I had to clean the filter twice, the second time I opened up the fuel line and let the fuel run into a container before installing the filter again. This happened on a Sunday so I cleaned the filter and all with dry gas (TWICE) .

I've had the problem before with other tractors. I little ice forms in an elbow coming off the tank and it will not run. Added gas line antifreeze, let sit a while and problem solved. yes I said GASLINE antifreeze. I've used it several times. One bottle in a full tank of fuel. Its not enough to hurt anything.

That is extremely interesting! Is that an official Deere notice or warranty item? I think I have a couple weeks left on warranty (have to check) and might want to see if I can get the dealer to do all that if it's something official.

It is a warrantable solution for the 5105 and 5205 tractors listed in the serial number range in my original post. Local dealer can find the information in DTAC. Basically, it's not a mass recall like the auto industry, but a recognition of a problem and willingness to take care of it if you encounter this problem of not starting in temperatures under 32 F.

Thanks

It has the same ingredient. Alcohol

Did you get it going and what was the fix?

 

[classic]

Yes it got it going. The fix is waterless fuel. But I've had to use deicer since caused by condensation. Works every time.
