    What might a spring pulling on a tensioner do?

    It looks far too simple for Yamaha. Why not use the $300 hydraulic version that will break when you look at it sideways?

      Wish there were more simple (and inexpensive parts) as well.

      Being its just tensioning a belt for a fuel pump, it's NOT a super critical part if it skipped a tooth. Heck it's been running without it for sometime now...

      Now the hydralic, fancy tensioners for the VALVE CAM SHAFTS, those are critical. Obviously you don't want it to potentially jump one tooth. The dampening with these tensioners, helps keep the belt tension more steady.

      I never took one apart, however, it's going to be much more stout than a simple spring which can (and DID) break...

        Plz point me out a CAM SHAFT. There is NO cam shaft for this set up.

        It is not a cam shaft, it's a ROLLER tensioner that uses a spring.

        This ain't brain surgery.
        Are we talking about the tensioner or the drive belt. The tensioner uses a spring to keep tension on the drive belt. The cam shaft drive belt.

        The cam shaft that activates the fuel pump. I point out to you the illustration depicted below.

        Then check your brain into the surgical department for an adjustment. Gotcha!

          Well if we want to parse words, the belt is titled in diagram as the "V Belt"

            Speaking of parsing, let's parse the belt. The V belt. The cam shaft drive belt with all of the little V shapes that interface with the V's on the drive gear and the driven gear.

            A cam shaft is not a cam shaft is not a cam shaft. A V belt is not a V belt is not a V belt. A Yamaha is not a Yamaha is not a Yamaha. As one might think of a cam shaft, a V belt or a Yamaha.

            Isn't this fun? With Yamaha you got to think outside of the box. Keep on thinking. Remember in Asia what we might think of being vertically oriented was always told to me as a kid as being horizontally oriented. But they are not Orientals. They are Asians. Being politically correct that is.

              You CS jr?

              The SPRING, that's what the thread is about, (read THE first post).

              The spring simply puts tension on the belt, PERIOD.

              Try staying on topic...

              And I don't really need the condescending smart a$$ remarks..

              Perhaps your *****ing...

                It is a two stroke. The belt drives a cam shaft. It is a cam shaft drive belt.
                Actually, the belt DRIVES a cogged pully. The pully is attached to a cam shaft.

                In either case (as you seem to like playing with words), the SPRING, simply activates the tensioner.

                  Well if I called my local Master Tech and asked "Tim, I need a camshaft drive belt for my Z200 hpdi, he would immediately tell me the engine has no camshaft." And then I would correct him. He might be irritated and say "why didn't you ask for fuel pump belt in the first place".

                  We should stop using terms for parts. Creates too much confusion. Only part numbers. But now that would be a problem too as many of those have been superseded. What to do? Assumptions have to be made. Arguements ensue.

                  I have a cam in my shifter in my car. At least that's what I call it other than a POS on bad days. It goes clunk when I shift. Secured by an M3 screw. Too damn small, comes loose and jams the thing where I can't shift. I said f it and used a little blue loctite.

                    Very true, BUT the thread is about one part, what is it?

                    It's very simple. It goes to the belt tensioner, (both in the pic and the link-which shows the parts #, where it goes and most importantly, how to get a replacement).

                    The BS with Fuel pump cams, etc, is that, BS..

                      Someone needs to get a sense of humor.

                      The third post in this thread described the spring. That should have closed this thread.

                      It was not me that brought the issue of no cams and no belts.

                      "Its a two stroke, NO cams/ cam belts." That was brought up in post #10. Why? I have not a clue.

                      But since the topic of no cams or no cam belts was raised it was appropriate to correct the record. This particular model does use a cam shaft and a cam shaft drive belt.

                        Nope. Yamaha says it is a V Belt. Doesn't matter the function.

                        So everyone is wrong......



                        OP long gone. Bet he has a flappy V belt...

                          Everyone else but you and I are wrong. When you are not around I wonder about you!

                            Guess I will have to linger a little longer.

                              my motor has a fever.



                              it is all about the jinglish.

                              the above motor does have a camshaft.
                              however it is part of a sub assembly.
                              the tensioner is not automatic it is manual.

                              most posters are nuts and have never actually used the tensioner.

                                What does this mean? they remove them, disconnect them, ?
