warrior starter help!

Ya i see the flywheel spinning on the crank. Id check the key

 

[codysisk13]

where exactly is the key located?

 

[codysisk13]

and how do i get to it?

 

[YAMAHAULER]

You gotta pull the flywheel off the crankshaft see the groove in the shaft there is supposed to be a half moon key to keep the flywheel from free spinning on the crankshaft

 

[YAMAHAULER]

is that right Beastly?

 

[bones]

Your starter clutch is done .... It's not grabbing the fly wheel and turning the motor over ... If it was key the rotor would spin as well and its not in the vid

I thought the flywheel was turning in that video and the crank wasnt or was my eyes playing tricks on me

 

[codysisk13]

Thanks for the pic yamahauler, i really appreciate it. I will check the key first then the starter clutch. what does the starter clutch look like and how do i get to that also?

It looks like the starter is spining in the wrong direction. Remember, the crankshaft turns counter clockwise while running. Meaning it has to turn counter clockwise to even start. Now, the computer I'm on now isn't the best, so vid is hard to see, but I swear it looks like the the flywheel gear is spinning clockwise.

Cody, when the starter turns over, with battery power, what direction does it turn? It should turn counter clockwise like the crank. When the starter gear turns counter clockwise it makes the idler gears turn clockwise, when the idler gears turn clockwise it makes the flywheel gears will turn counter clockwise. If that flaywheel gear is turning clockwise IT WILL NOT TURN THE ENGINE OVER. Just double check that, because I wanna beat money on it that its turning the wrong way.

Hold that thought ill go look at my other motor after classes and take pics, it slipped my mind where the starter bearing is

the fly wheel gear is spinning but the rotor is not and (@gen1pat) it is spinning counter clockwise in the 2nd vid but as you can see the the starter clutch is not gripping strong enough to spin the rotor witch spins the crank

@codysisk13 this is the part you need im 99% sure have build 3 of these motors form empty case to running http://www.ebay.ca/itm/NEW-Yamaha-W...ccessories&hash=item4ab5eaec2b#ht_1031wt_1037

My starter is spinning clockwise

ok sounds good. thanks

Thanks bones. So if this is it, how would the starter clutch go bad in the first place? just wondering?

its just a roller bearing that grabs one way, the little bearings inside wear out and it just quits grabbing

Look really good at the idler gear shaft. The very tip of it has very distinctive oil smudge on it. It looks to be turning to the left (counter clockwise) it needs to turn right (clockwise). When it turns right, it makes the crank turn left (the way the crank is supposed to turn). My dad was standing right next to me just now and he saw the same thing. I don't care if he and I are wrong. If we are no big deal, we must be high or something. Just look at that idler shaft again and confirm or denie that it is turning to the left.

yes the idler gear is turning to the left (counter clockwise). and there is a oil smudge because i took the shaft out of the stator side of the motor, it that is why that tip is covered with oil. i just took it out and slipped it in the gears were so i could run it with starter hooked up.

oh i see, that makes sense. thanks beastlywarrior228

I only mentioned the oil smudge for people watching the video to use a reference mark, to see that the idle gear is turning to the left (the wrong way). The crankshaft HAS to turn to the left, period end of story. If the idler is turning to the left it Will make the flywheel gear turn to the right. Since the flywheel gear is turning to the right, how in the hell can it make the crankshaft turn to the left?! The flywheel gear has GOT to turn to the left, to turn the crankshaft to the left. Your starter motor is turning the wrong way. The start motor gear HAS to turn to the left, to make the idler gear turn to the right, when the idler gear turns right it makes the flywheel gear turn left. Lets do a little experiment shall we? Reverse the polarity to your starter.

Simply put the NEGATIVE cable to the POSITIVE lug on the starter. Then, put the POSITVE cable to the frame and use it as a ground. This will reverse the flow of electrons and cause the starter motor to turn in the opposite direction. When it does this the flywheel gear WILL turn to the left. Don't worry you will not get electricuted.

Just got to watch your vids with sound(other shop computer has none). The reason why you couldn't turn the idler gear to the right by had was because the starter clutch actaully locked in place, and had you put more strength behind your turn you would have gotten the crank to rotate. The idler will free wheel to the left all day long because it spins the flywheel gear opposite of it's lockup direction.
