AdBlue problems on combine engines.

[Pilatus]

Do any of you have Ad Blue problems on your combine engine , irrespective of make?

 

[Farmer Roy]

No

 

[Acke]

[MrNoo]

Not as yet, not looking forward to the day though!

We just got a new combine with ad blue on it. Ours is a new holland with the tank up on the top so will need a very long pipe to reach. The tank holds 150 litres and is using 1 tank of ad blue to 2.5 tanks of diesel. Been filling with small drums so far but not ideal in the long term. Be interested to hear how people are filling theres. 12v ad blue pumps are very expensive

use drums as too high for gravity feed keep filling it up every day takes less time than filling with fuel

I have had problems with add blue on the previous combine due to temperature sencer on the exhaust took a while for dealer to sort first time went on derate on a sunday afternoon dealer not available was mighty peed off and when combine was changed have a different make
the other problem was when the dealer fitted the batteries the second battery was not fitted properly so the combine lost 24 volts leading to the system going besurk sorted once we worked out the issue

Even filling every day will require approx 50 litres each time, trying to get it to the field is the problem as no one wants any drums in the tractor cabs. It is turning into a bit of a nuisance, we need to make it easier somehow

My experience with the early ad-blue trucks is that the key to avoiding ad-blue issues is to keep everything squeaky clean. Any sort of dirt, dust or liquid contamination will lead to problems with pumps and dosing units.

Keep the filling nozzles off the ground, don't use old recycled containers and under no circumstances allow water to contaminate the system at any point and there should be few problems.

We got a 12v pump from Spalding and I mounted a 200l drum on the drawbar of the fuel bowser it made life a lot easier And splashed out on a self stopping nozzle for it you don't want ad blu running over

This sounds the job.
We currently have a mini 600 litre ad blue tank on our 1 bowser but it only has a hand pump and a short hose. Even extending the hose long enough i fear it wont have enough force to pump it high enough up to the ad blue tank

We bought an old ex plant hire bowser fitted up our 12v transfer pump to it and I extended the drawbar got an old ad blu drum from a friend and fitted it up and we just run it out of the ibc when needed

50ltrs a day? Seems pretty steep usage? My NH (cx 6080) uses hardly any at all in comparison, I tend to put a couple of 10ltr drums in whenever I fill the main fuel tank up. Guess yours is a much bigger engined machine.

Its a new cr8.90. Have only cut rape so far and chopped most of it so she's working quite hard.
The fuel tank according to the book is 1000lts and the ad blue is 150lts. Its done 2.5 tanks of diesel to 1 tank of adblue so far. I filled it up again today with small drums and was painfully slow carry each one up the ladder.

eBay. £60 for a 12v pump and auto shut off nozzle. 60-80l per minute.

These seemed to be the cheapest but still not that cheap

Trouble being that a lot of these pumps are really diesel pumps and as such rely on the diesel or oil etc to lubricate the pump, not sure of the lube properties of add blue, but guess you could get through quite a few pumps worth before you reach the cost of some of the add blue pumps.

 

[Ducati899]

I use these for ad-blue,current one has done well over 12 months

Have you used it with AdBlue though?

Proper AdBlue pumps are diaphragm types and the nozzles will be plastic or stainless and no brass, copper or gal pipework in the supply as it will get attacked by the urea and lead to contamination.

Then you will likely have NoX sensor or other issues on the dosing side.
