580c case backhoe

[walter shea]

my 580c is having some kind of fuel problem? in the winter it started stalling out after it ran for a while i thought it might be water in tank so i heated up bottom of tank and drain some water out put new filters on and that did not fix the problem it would run for 15- 20 min then stall out if i waited a while it would start back up i heated up the pump and that seemed to help it would run till i was done i thougt there was water freezing in the pump but i stared it the other day and its doing the same thing and it was 80 degrees out It runs for only a short time if you let it sit for 4or5 min it will start right up and repete the cycle of runing for only 2or3 mins?

Where the main fuel line inters the pump there is a fine screen take line off then unscrew the larger nut the screen is on the end of the nut it wil be stop up.

If it has the Stanadyne/Roosa Master injection pump, check for debris in the small fitting in the top of the pump. The fuel returns through this fitting and if it becomes plugged it will run a while and cutoff. There is some part inside the pump deteriorating if you find anything in it.
