Yamaha PW-X - Giant Trance e+ 2019 - Stripped Flywheel - Motor Replacement

[biker23]

This is the result of a pedal strike - $1,800 AUD - Thankfully covered by insurance.
I have found the COG for $700 Pounds - But didn't appear to be readily available. Thinking of using a 3D printer

Any thoughts out there

Wow! What was your feelings? How did you know something got broken?

I can't suggest 3d printing... at least not home 3d printing. I have some experience with them and I don't think the piece will last for long and won't be perfect shape...

Yes a little shocked - Intitally though Warranty, but it was a pretty hard knock - Poor design in my opinion.

When the cog and drive pin got to the point it just free spun.

Yes I agree on the 3d printing - I wouldn't have thought you could have Nylon that strong - Apparently they are available to replace in the UK for 700 pounds - So $1,400 AUD.

If you're in Australua, can you approach giant Australua and see if they have that gear in any returned motors or if they could sell you a used one from a warranty motor?

Even if you waited until they got in the replacement motor for someone who is currently awaiting a warranty motor.....

ps Where in oz are you? Anywhere near stealth in springvale vic? I suspect they would have contacts who can build helical cut gears out of stronger material if you want to

Hi - Good Point - Will chase that one up. Im in Sydney - But have a mate in Vic

Thanks for that

Hi, one of your team emailed me to advise they don't have any - And referred me to avdweb. They advised they are a few months away from manufacturing them. (As per their website) - But if this is wrong - Happy to purchase

Email link was: Yamaha PW-X2

 

[Bearing Man]

Don't worry, we have parts coming and going all the time. Unfortunately we can't keep track of who wants what as we get asked on a daily basis for all sorts.

For anyone else panicking about their gear, this us the link for advweb he mentions

Here, I share technical solutions that arised during the development of my solar-bike.

Makes me wonder how common this problem is and why it's NOT a warranty problem when the gear dies from a pedal strike?


Logical argument to Giant - if they don't have any serviceable second hand gears from motors with electrical gremlins, then perhaps there is a design fault?

 

[Code54]

Have a local machine shop machine one from aluminum perhaps.

 

[Dgedge]

I won't make a new cog in aluminum because the original nylon one is probably :
1 used like a fuse to avoid damaging other (costly) parts inside the motor
2 used to reduce the noise of the motor

Possibly any local machine shop can machine nylon as well as aluminum ?

 

[DrStupid]

There are motors on ebay right now if @Bearing Man cant get you a gear soon enough. You could likely take your needed gear out, and sell the other components for a net wash.

This is not a common failure. There are no common failures with yamaha. There is nothing to see here. The parts are fine.

Hi, Just wondering if you have any of the flywheels for the Yamaha Motors which I stripped - I ended up getting an insurance job but would like to fix my motor

Thanks Andrew
