I would like to remove the Robert Bosch injectors from my 7520 JD tractor. They have the 12 point nuts at the bottom of the injector to push them out or pull them in. I have used a box end wrench on my 4230 as the injector was round after removing the leak off pipe. Only thing with these ones, the injector is Y shaped at the top so a boxed end wrench won't go over the top. Manual said to use a JDE 69 wrench to remove. Would these still be available or could one just cut a piece from a box end wrench? I'm thinking there may be a sticking injector as there is kind of fluttering on acceleration and fire balls up the pipe on de-acceleration. I had a leaking injector line that I replaced and it started shortly after that. I cleaned the injector and pump area with brake clean and air about 5 times and removed the alternator and all the lines and stuff. The new line was in a sealed plastic bag and had plastic plugs screwed in the ends. With all the stuff removed it was a easy fit for the line. Didn't have to twist and rotate and rotate and twist again to install. Thought it might be the turbo but I think it is ok. Any other thoughts. Thanks for now.......Ron

Today's Featured Article - Box Plow Blues - by Tom Schwarz. One of the first implements most tractor owners obtain is the box plow. For very little money, this piece of equipment promises to plow and flatten any hill or vale on your ranch road or farm. At least that's what I thought! As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U
