Re: Yamaha Drive Brakes
I have worked on Club Car brakes which have the two shoes in each rear wheel, but some of my friends have late model Yamaha golf carts, which have no brakes in the wheels, I understand from reading this forum topic that the brake is in the differential.
One of my friends had what he thought was a brake squeal noise, and it turned out to be relative motion between the axle tube and the axle shaft. The tube is just a simple tube between the inner race of the differential end axle bearing, and the wheel end hub. Is that tube supposed to be trapped by a high torque on the wheel end axle shaft nut, such that it rotates integral to the axle shaft, or is it just a spacer and that outer nut should just be snug and allow relative rotation between the the axle shaft and that tube? The way it was when I looked at it was loose enough that there was relative rotation between the shaft and the tube, but I am thinking that maybe that should be tightened up enough to stop relative motion, and use that tube as part of the axle structure, since it looks like it locks against the differential end bearing inner race. It's a castle nut with a cotter pin. I intend to donate to this forum if I get a good answer to this question. |

Re: Yamaha Drive Brakes
Thanks! I'll tighten that axle nut down to ~80 foot lbs and make sure everything rotates properly while jacked up Tuesday.

I agree with you that it makes sense that these tubes be tightened down with the wheel end axle castle nut, assuming there is a sufficiently axially attached axle hub inside the differential to react the axial force, against the inner race on the differential side. If these tubes are not tightened down axially, I see no use for them. If they are tightened down, they would add bending strength to the entire axle from wheel hub to the deferential axle gear. If you could provide or refer me to some type of official procedure for tightening these axle nuts that would confirm that they are coming from the factory wrong in 2 cases, it would be greatly appreciated. I made a $10 donation to Buggiesgonewild, thanks for your response and dealing with this technical issue. |

We see this problem on alot of the carts the nuts will come loose on the axle hub. If you don't tighten them up you will spin the hubs or it will fall off. |

Re: Yamaha Drive Brakes
3 for 3 Yamaha carts looked at so far have loose axle tubes and finger tight torque on the axle bolts.
