David Brown 1200 rubber line

Post by fcagle » Tue Apr 23, 2013 1:16 am

On my newly acquired 1200 their is a rubber hose coming off of the fuel return line at the back of the fuel tank. The line is folded and taped off. Does anyone know what this does and where the line goes? Appreciate any help.

It's probably a result of a brainwave from a previous owner to either overcome a problem or a modification, as Calvin suggests. Farmers have very creative minds and it never ceased to amaze me what they would think up to solve a problem. You just need to do a more effective repair, perhaps get it brazed up.

Thanks for the comments. After a closer look it appears that the line was cut off from the air intake. I found a little piece of rubber hose on a nipple on the intake. If anyone can confirm that that is correct it will be a simple matter to replace it. However, I assume that the intake would create a suction on the fuel return line and allow a small mist of fuel to be added to the air. Any additional comments would be appreciated.

Without seeing a picture, if I'm correct, it's nothing to do with fuel, it is the engine breather pipe from the top of the rocker cover, passes forward over the top of the radiator and onto a short bit of pipe on the side of the air cleaner body. This breather pipe was fitted to later Implematics and early Selectamatics but soon choked up if the breather filter and pipe was not serviced regularly which led to higher engine crank pressure. This was later replaced by a larger breather pipe that vented down the side of the engine block into the front hole in the chassis void.

Probably fuel supply to the thermostart(glow plug-manifold heater).

Does the fitting in the manifold also have a large male spade type electrical terminal on it?

About like this one?

The fitting is slightly different but that is it. It appears that the fuel line goes to a splitter type fitting on the fuel return on the back of the fuel tank. Does that sound correct? Also, their is no electrical connection. I assume that their should be a wire from the key switch to activate the glow plug. I will attempt to add a couple of pictures to confirm. Thanks for the reply.

That engine and associated lines are not a 1200 engine. Might be what had some puzzled, or maybe they are just naturally confused.

Your assumption about the wire is correct, it would go to the spring laded position just before "start" on the key switch.

Looks to be a late 1212 or 1210 engine. Any more pictures of the whole tractor?

I will try and take some more pictures this evening along with the serial numbers of the tractor and engine. I will admit I couldn't figure out why the previous owner would fold the rubber line back on itself and tie a wire around it. I'm not the sharpest knife in the drawer but I was pretty sure that it didn't come that way from the factory.......................

As the saying goes, here"s the rest of the story. The serial number on the tractor is 1210/1 726887. The Engine serial is AD4/55A 25516. So, even though the hood says its a Case/David Brown 1200 its really a 1210 with a different hood on it. I also know why the supply line was folded back and tied up. The Glow Plug is broken and leaks badly and will need to be replaced. So instead of replacing it they just folded up the line. I appreciate all of your responses helping me to sort this out. As I said I'm much more familiar with the 880 models than the 1200 series. This is a whole new learning experience for me. Thanks again.

Some people should be allowed to play with stickers... They Couldn't get them right in Kindergarten, and still don't. The is no such thing as a Case/DB 1200... Case built a 1200(big 4x4), and there was the DB 1200... I have seen this decal set on other tractors and it always makes me shake my head.

Tac Cable is broken. Went to replace it with one of my spares and it won't screw in to the engine. My research tells me that my 1210, serial # 726887 is early 70's vintage. Did David Brown convert from standard to metric along this time? My part number is K311487. However, when I look for a replacement the same part number is used for the 1200 and the 1210. I'm sure some of you have already been done this road and I don't want to order the wrong thing so any assistance you can offer would be appreciated.

If the outer sheath of your original is ok then you may only need to replace the inner cable. Take note and look at the screw end on the engine to see if it's a fine thread, which it probably is, as most of the 'new' tacho cables available have a coarse thread engine end and won't fit.
