Heater plug

I bought a heater plug for the manifold, it appeared to be to big for the hole it was meant to go in (to long). I stuck my finger up to see if there was an obstruction and it appeared that there was. On top of the manifold was another plug with a fuel pipe attached. Looking at the parts list I think this is an atomiser. Can anyone explain if both are required as it appears that they both don't fit it's either one or the other. I removed the atomiser and it looked broken. I haven't got the facility to upload photos yet but I am working at it. Can anyone reccomend a host site?

Yes on the Dexta both are required. One plug squirts in the fuel when you work the primer. The other is the heater which does just that, press for 40secs then press the starter whilst you give a few squirts on the primer. The manifold is easy to remove if you need to take a closer look at the plugs.

I upload to Photobucket; seems to work the adverts are a bit of a pain at times but that's life. :wink:

Does the heater plug have a shroud of sheet metal around the coil and a pipe fitting in the outside end? If so it's not a heater plug for the dexta... using one of those instead requires a bit of remodeling of both the manifold and the piping for the heater... not recommended if you want to stay original :)

Where can I get a new atomiser, agriline have never heard of it!!!

The one i've taken out has the following stamped on it "BERU W. Germany 154 GS 12V" It looks more like a spark plug now I have taken the damaged metal sleeve off. I have tried to blow through it but it feels solid.

Hi , idont think there should be aheater plug in the top of manifold this is probley some sort of an after thing , the heater goes up through the bottom , the diesel line goes in the side above the the heater plug . the modern type can be used but is as said its not orignal if thats what you are after. there should be a shut off valve on the diesel line going into manifold .

It isn't a heater plug in the top Gerry, it is where the fuel comes in when you press the primer, I've tested the fuel line and it comes out lovely when it is disconected from the atomiser. I've just had another good look at this top "atomiser", it has a 12volt supply attached to it so it appears that it is some kind of additional heater, a heater as well as heated fuel. Should there be a hole in the top of the manifold, I don't think so. Where should the fuel from the primer enter the manifold? This hole in the top appears to have been drilled as an afterthought!!

Has anyone got a pic. of a manifold with fuel lines attached?

The original setup on a Dexta consists of a large coil glow plug that is screwed in from the bottom of the manifold and an atomizer screwed in from the side of the manifold directly behind the glow plug(nearer the air filter hose)

The thing you describe is a different kind of heater plug, look at this image http://iloapp.b20power.com/data/_galler ... esized.jpg this type of heater plug attaches pretty much like in this picture http://iloapp.b20power.com/data/_galler ... esized.jpg

The pipe from the injector return line goes to a tank, the bottom outlet of this tank goes to the heater plug and another line at the same height as the injector leak off pipe goes back to the primary fuel tank... as you run the tractor this tank fills up and when you need to "glow" her you just press the button, the elements in the glow plug will heat up, pull out a small valve and let diesel into the element inside the metal shroud and voilá, you have a flamethrower in your manifold... I've modified my dad's super dexta to have this kind of heater plug as well as my own Super Major... see video here: http://www.youtube.com/watch?v=g9r3wiHJIhQ

I'll post some close ups of my spare manifold tomorrow where you can see down the inlet and also the heater plug.

Look forward to that Jerry.

There is the clue.....that item you have removed is a glow plug.

Beru are about the biggest manufacturer of modern diesel glow plugs so I would say that somebody has added a second one to the setup (or fitted a modern one) where the atomiser used to go.

the atomiser is actualy little more than a jet....agriline do sell the fuel pipe but not the jet

The atomizer use to go where the plug on the side of his manifold is, there aren't supposed to be a hole at all in the top of the manifold so that has been done in order to add the beru glow plug...

When I converted dad's super dexta I just re-threaded the original glow plug hole and screwed the newer kind of glow plug in, it really works a charm but if the idea is to maintain originality it's not an option... anyway, you can make yourself an atomizer out of that plug, drill a hole through it, solder a piece of 3/16 copper pipe in it and flatten the end of the pipe that's facing inwards inside the manifold, leaving a hairline gap for diesel to pass through...

Thanks Foxen, good observations and a good idea for the atomiser.

Looking at your pic again.

The correct hole for the diesel atomiser has been blnked by a bolt.

where you have removed the new glow plug from is a new non standard hole.

If going back to the original setup then I would plug the new hole and use the original one as its probably better placed to atomise fuel over the original heater

Plugging the hole could be difficult but I won't go there.

Can you not insert a short bolt in it or braze a nut onto the casting to support the same fix?

The manifold is made out of cast aluminum and I'd be very wary of brazing or welding anything onto that since each different alloy has it's own "additive"(the material you add when welding or brazing), the last time I heated something out of cast aluminum up it nearly vaporized and I was lucky to have one spare... no pictures of the disaster tho :(

Good observations, be assured I won't be taking any risks, I am on the lookout for a replacement if any one has one!!!

Here is a link to my tractor picture where I've put the manifold pictures.

http://s307.photobucket.com/albums/nn28 ... 0Pictures/

The adaptor for the fuel line going into the manifold contains a small ball bearing held in place by a small spring. When you push in the Fuel tap pump the pressure overcomes the spring and the ball lets fuel past into the mainfold.
I think it was there to stop the manifold vacumn sucking fuel in and also to stop fuel leaking into the manifold when the engine wasn't running. If the tractor has been standing for dome time and water in the fuel gets there I'm sure the spring and ball would have rusted. I cleaned mine up with just a light push on the ball into the manifold.
IMHO

Thanks Jerry

If you stumble across one in your travels give me a nudge.

could you make a neat patch for your manifold and rivit it in place. use a bit of sealent, wont look perfect but should work nicely. or could you tap the hole to fit a large drain plug to fill the hole?

Thanks, good suggestion but I can only carry out the easiest of tasks.

How about fitting a small coach bolt into the hole and fixing with the chemical metal type stuff (as seen on TV and available in Tesco etc).
Once set you can grind it down to match the profile of the casting and once painted will 'dissapear'.

Nice one Jerry, we could make this a fun competition how to fill the hole, winner gets an APUH for a Ford 2000 LOL

Sorted, picked up a manifold this afternoon £25
