im having starting problems. i have a new batt, solenoid, starter, my neutral safety wire broke but i also replaced it and still no start. i turn the key on, the neutral light comes on, i push the start button, solenoid clicks once, and the starter spins but nothing happens. i believe im not engaging the bendix or fly or something......any input??

That would be my guess also... if you hit the button and all you get is a zing from the starter I would say the drive gear is bad on the starter. pull it and bench test it and see what it looks like. check your flywheel too while you got the starter off

Your one-way bearing is bad in your starter gear. It is located in the big starter gear on the back of your flywheel. You will have to pull your flywheel and the big starter gear just pulls out of the one-way bearing. Then just unbolt the one-way bearing from the back of the flywheel and replace. There's no need to remove the starter.

The 400EX don't have a bendix. They use a one-way bearing. The one-way bearing bolts onto the back of the flywheel and the hub of the big starter gear fits into it. It has to be the one-way bearing unless you would have some teeth broke off one of the gears, but I doubt it.

It's #5 in the diagram below. Honda calls it a clutch, but it's actually a one-way sprag bearing. It allows the big starter gear to only turn free in one direction and it will catch in the other direction. When the bearing goes bad, it will turn free in both directions and that's why the starter won't turn the engine over. #5 in the diagram below.

I forgot to add that it's $84.38 plus tax at my local Honda dealer. You might be able to find it cheaper somewhere else.

Helmut,

Is there a part on that clutch that wears out? Can it be adjusted, are there any repairs possible other than replacing?

thanks,
Jim

Jim, You need to replace that bearing. (Parts within that bearing are not replaceable).
