1210 David Brown injection pump help please

[DaveZ]

I recently finished a two year project of changing the head gasket on my 1210, I just put the head back on and all of the fuel lines and related parts. I bled the system and found that I am only getting fuel through the line closest to the fan. Is there something stuck in the pump because it has sat for a couple years? I have ample fuel with no bubbles at the bleeders and the filter. Any Help would be appreciated....Thanks

Not totally familiar w/ the Browns, but didn't you have to pull the fuel stop out to run & in to stop? Other than that, I had to loosen all the lines at the injectors on a 1490 once to finally get it to bleed.

There is a sequence you have to go through..bleed the fuel filters first with the middle hex head bolt located at the top of the fuel filter rack between the filters...then bleed the inlet into the injector pump. Crack open all the injectors connections and turn the motor over until fuel starts coming out. That is what I did to a 1210 last week that had not been running
in over 5 years...She fired right up....Also have you checked the oil in the fuel pump??? That injector pump holds about 1 pint of oil.....

Is it a Simms/Minemec, or a Bosch pump?

 

[DaveZ]

Thanks to all who responded, it is a Sims pump. I changed the oil in the pump, and have good fuel delivery at the pump. I worked on it today and have fuel at the front two lines, and it will run on the two cylinders. I am thinking that it has to be the two remaining pistons in the pump are still gummed up and not pumping fuel to the injectors.....any thoughts?
Thanks again
Dave

It is a sims.
Thanks

Thanks for all the good advice, I am the second owner of this tractor and have owned it for about 12 years. I am anxious to get it running again.

Does the cold start button on the pump have any effect? does it "click"when you push it in?

I think if it was me, I would run it for a while, at least till it got up to operating temperature.

 

[DaveZ]

The cold start button does click and and seems to be working right by dumping more fuel into the system. I am perplexed as to why I only have two of the four lines receiving fuel. I let it run on two cylinders for awhile last evening thinkng that the pump would free up. Are you familiar with the Sims pump? Is there a plate you can remove to see if the pistons are moving freely in the pump?
Thanks again
Dave

I have a spare here on my workbench... I walk by it many times a day(when the CAV rotary on my 1394 gives up, it will be a donor). Familiar? I don't know. Other than changing oil in one, I never had to do anything with them.

The side cover looks to come off easy enough. Just have 2 cap screws to remove the side plate. See what is moving on the cylinders that are working and what isn't moving on those which aren't.

Thanks again, I will dig into it tomorrow and let you know what I find.
