  • F150 Timing Belt

    I have a 2004 F150 TXRC with 560 hours. The Yamaha service charts say to change the belt at 1000 hours but what about a time factor? Also what about the fuel pump diaphragms? Do they have any known service life? What would be the shop time to change the timing belt? Any thought are appreciated.

    Thanks

    Time is a factor, I would certifiably look at the belt, change if it looks cracked or you are worried.
    Should take hour or so, depending of is doing it and location of boat.
    Fuel pumps same thing, what kind of fuel, etc.
    Rubber does get old, I have seen 04 engines that have not had that stuff changed.

      I have never touched the lp pumps on my 2005 F150.
      Is there a kit to rebuild them?

      I haven't seen SIm on here in awhile....

        Summertime for Andy, he's up to his Yamaha in boats.
        I'll look and see if there is a kit, but I don't think there is.

          I ordered part numbers 29-diaphragms and 42-o rings, hopefully that's all I need.

              The only part that keeps me from changing the timing belt myself is removing the flywheel and torquing it to 200 FT-LBS. Any tips or tricks or special tools for removal and reassembly? I do have the factory service manual.

                A pneumatic or electric impact wrench is great for removal of the bolt - no flywheel holder required
                Pulling the flywheel is often a trial for us DIYers; you'll need a good quality 3 bolt puller, and if you can get them, high tensile metric bolts.

                may need the impact wrench to tighten the puller,
                and still may take more than a day of everything else you can think of - without causing serious damage: heat, tapping/hammering, penetrating oil

                Reinstall torque by comparison is easy,
                There are special holding tools but another pair of hands and a big pry bar gets it done: many ways to brace against the flywheel to keep it from turning

                  I agree with Lucky Dog. Spray some break free on the flywheel nut (or bolt). Put an impact on it and it will come right off. To tighten, use an automotive flywheel or flexplate tool with a torque wrench.

                    I just recently realized who Lucky Dog actually is! Good guy to have here.
