Wow Joe, your diagnostic skills are absolutely amazing. It's so nice to see a 2-dollar woodruff key fix this problem. It's about time you had a cheap fix as you usually have to pump many dollars into fixing these machines that you purchase. This is a good buy that you thoroughly deserve as not many cheap fix bargains come your way. Well done Joe, your never give up attitude and perseverance is most commendable indeed. Cheers Dave from Port Elizabeth, South Africa.

@racequad9 Жыл бұрын

what caused it to keep shearing off the key?

@kryten1021 Жыл бұрын

@@racequad9 the key only locates the flywheel in it's correct place it uses the contact of the taper on the crank and the taper on the flywheel to keep it in place , if you find a sheared key and the two surfaces aren't good its always best to lap them in using valve grinding paste until you have good surfaces then clean all grinding paste off and fit a new key and tighten to the specifed torque, another tip i've seen people fitting too tall a woodruff key thats prevented the tapers meeting and keeps shearing the key, oh also don't lube the tapers I've had customers that have lubed the tapers on cranks too, the contact areas should be dry, possible causes are flywheel not tightened correctly or tapers not good or wrong key fitted holding the tapers off each other even when torqued correctly

I really enjoy your videos, so I just subscribed for more. Growing up decades ago on a small, rural farm, we had to work on everything from lawn mowers, ATV's, trucks to tractors, so it is nice to see youth who actually know how to work on machines. Often, I tell young people today to learn a trade skill instead of going into very deep college debt and then not earning the salary they thought they would. Locally and now living in another state, it is near impossible to find anyone who knows to fix modern machines.

I had an 04 sportsman 600 I bought new. Great quad. Never any issues with it. When you are in 4x4 and go in reverse you only get rear wheel drive unless you push and hold over ride button. This will engage the front wheels while in reverse but it will engage rev limiter at part throttle. I assume that is what that set of contacts in throttle are for.

@rolop847 5 ай бұрын

The contacts in the throttle is for when the carb cable gets stuck wide open, so it then shuts down the motor (no spark)

I got a Warrior 350 he kept bump starting because the one way starting gear was out and he didn't replace it. So when I got it and replaced it shortly after the woodruff key broke I know that quad can't be bumped started but just thought I'd throw that out there too. They are important and can break easy plus cause complete loss of spark or intermittent. Good score as always buddy!
