Re: Clutch Engages BUT Cart Stays Still
It looks like the ramps aren't aligned with the slides on the sheave. The flat spot on the ramp should run flush on the slide
That stiff torque spring probably isn't helping things... |

Re: Clutch Engages BUT Cart Stays Still
That makes sense.
When I put everything back together I used what it looked like before as my reference. I will disassemble and run the ramp and slide tight. If the torque spring is designed to help, why would it be hurting the cart? New parts matched with old worn out parts? |

Re: Clutch Engages BUT Cart Stays Still
I've got a Yamaha u-max spring, which will work well for you. OEM Yamaha. It's 6" long and used in the Yamaha utility carts, like my G11. The clutch in the pic is gone.
$25 plus postage. |

Does it seem odd to you that a splined spacer was already on the cart and half moon key was gone? |

Re: Clutch Engages BUT Cart Stays Still
"The infamous white spring", classic problems for that stiff of a spring. Those springs have been notorious for causing clutches to not work correctly. I suppose if the clutch was "like new" maybe the white springs work ok, but still not good. That Umax spring will do you a favor! Dave in VA is a good guy, I bought the clutch in the pic.

Re: Clutch Engages BUT Cart Stays Still
One of the first things I do when looking at clutch operation is I put the rear of the cart on jack stands and run the engine. Watch the clutches. They should engage smoothly with no wobbles or noise. Run the engine at full throttle, the clutches should shift all the way without noise or wobbles, need to be smooth. You're also looking for the belt to ride all the way to the top of the primary clutch, which indicates that it's closing all the way. The secondary clutch open up and allow the belt to ride all the way down in the sheaves. Another thing is you can take a black Sharpie marker and draw lines on the clutch sheaves. After running the engine full throttle, look at the sheaves to see how far the black marks have been rubbed off, that will tell you how far the belt has traveled.
Make sure you use good quality jack stands under the rear end. Also make sure you use wheel chocks on the front tires to prevent the cart from rolling. Safety first! |
