john deere 690d-lc injector leak

   Is that a 359 engine?! Them little pencil injectors are easy to change. Remove the return lines and unhook the pressure line. Remove the 5/16bolt. With 2 little pry bars work it up and out. Never seez the new one before putting it in.

   EASY is right on the money.. Just be careful and don't force it.. they WILL BEND.. They make a tool for such a job but it costs 130.00 and not very cost effective for just 1job, unless they are REALLY STUCK.. Clean the area well and give it a try.. if it doesn't wiggle.. spray it down w/ penetrating oil.. Twist and pull.. REPEAT.. Clean the bore w/ scotch-brite, spray it down, bump the engine over to expel the gunk, lightly coat the new inj. w/ antiseez and reinstall.. IF u have a torque wrench, use it.. if not.. snug it down and check for leaks and tighten from there.. The leak is probably caused by a bad carbon seal at the end of the injector.. It can be replaced for less than 10.00 at the fuel shop.. A new carbon seal and a clean bore and your back in business.. probably..

   Them pencil injectors have a sealing ring on the body. Wiggle and push the new one in. Sometimes a little tap with a hammer helps.

   First question is, where are they leaking? If it's just around the tee fitting at the top you just need seals and maybe some tee's and nuts.

   I missed the link I guess. All that injector needs is a dollars worth of seal rings and 30 minutes work..... YMMV

   x2 on Lans post.. I said 10.00 on account they will probably charge for a pop-test and labor to install the new seals..

    Seeing new ones are about 60.00 each.. you be the judge.. I've heard both good and bad about aftermarket injectors. I only use factory injectors, so I cant say personally.. IF its not smoking or hard starting.. leave it alone and just fix the leaker.. IF you do change all of them.. keep the old ones and CAP THEM OFF.. The new ones will come w/ protection caps for the inlet and tip.. transfer them to the old ones for possible future use.
