    driver clutch help

    I have a max 2 with 14 hp briggs. I am very new to the 6 x 6 world, so this may be a easy question. It seems that my driver clutch is stuck open, or i think it is open. The belt is laying down at the bottom of the shaft. When the engine is throttled up should i be able to see the clutch close up and the belt ride to the top? If so, what should I try to do to free it up?

    I assume you have a comet 780 clutch setup. it should function like this:

    There should be three small bolts and a snap ring that hold the dome cover on the clutch. Also there should be metal tabs bent against the head of the bolt to prevent loosening. bend the tabs out of the way and take the cover off. Perhaps all the moving parts have become corroded and won't let the clutch move. Oil is your enemy on the clutch because it will make the belt slip, BUT, I don't know how well non-petroleum based lubricants penetrate.

    So from the video it looks like I have another problem. My driven clutch does not move either. One problem at a time. Should I be able to remove the dome without pulling the motor?

    Post a video or a least a picture or 2 of what you are dealing with. A video would have to be hosted by another site such as you tube, facebook so you could copy the url.


    My new beer holder spilled some on the trails - in it's hair and down it's throat.
    Joe Camel never does that.

    I will try to do that later today. Should the clutch be moving in and out even with a stretched belt? The one I have on now is very loose.

    Depending on what rpm you are turning, yes. But without seeing what you are starting with all these answers may be moot.

    Yes, but why not just take the entire clutch off? Remove the 9/16" -headed bolt and the clutch will slide off the keyed crankshaft. It might take a little wiggling or prying, but there's nothing other than the bolt and friction holding it on.

    The drive clutch should pinch in based on RPM, closed fully at full throttle. It will do this regardless of the belt on it or if there is a belt at all. With the engine off the belt should fit loosely around the chrome axle in the middle with wiggle room. As other have said photos and video will help us.

    There is only about 1" between the top of the dome and the side of the tub. Is that enough room to get clutch off?
