Electric Starter Won’t Start! | Bendix Replacement

The Bendix Gear, or Starter Drive, expands to connect the electric starter shaft to the ring gear on the flywheel. And when the bendix breaks, the electric starter on your dirt bike is useless. As more kickstarters are being removed, the question I'm asking is "should the bendix be a piece that can fail so easily?".

Luckily for us DIY mechanics, the replacement of the bendix is fairly simple. You remove the ignition cover (watching for the dowels), slip the broken bendix out, and slip the new bendix back into place. I decided to replace the double pinion starter gear on the Sherco as well, because in the past six years, it looks to have been updated. This added a little bit more complexity to the job on hand, but so far, I haven't screwed anything up 😬.

Great video as always! Wiki -Bendix :A Bendix drive is a type of engagement mechanism used in starter motors of internal combustion engines. It is named after its inventor, Vincent Hugo Bendix.

Hello, a video about changing the brushes on the Sherco starter motor. Regards.

I have around 110 hours on my Sherco, I've cleaned and greased the bendix maybe twice? Probably will replace the starter/bendix when I get to the next top end rebuild as preventative maintenance. Also, why do you have the external power switch? Is that the solution to roll starting/waking up the ECU?

My 18 beta 2T didn’t have a kick starter but I was able to put one on at 400 bucks. I think it was well worthy the $ to upgrade and not get caught in a ditch somewhere with no way to pop start it

My 23 XC almost left me stranded for this same reason. Bikes really do need a kick start - all these new batteries with backups and added capacitors are NOT enough.

Hi, Speedfight2 100, my bendix is just spinning and not coming out do you know why that is ?

[jossessanchez]

well, how many hours did you change the bendix???

[MrBobbit]

reiju still has a kick start amd carby so she kicks into band like a real 2 stroke

That’s the first one I’ve seen that you don’t have to pull the whole starter motor out?

[PhonixxTheArtist]

If my scooter ran but died out while riding can the Bendix cause that issue ? Or is it only used while starting over the engine ?

Where they actually bearings? KTM use s little bushings for the old 8 to 16 style horrible starting system. You can upgrade to bronze bushings that will actually last. KTM's is similar, but the "sure can't" design looks a bit better. Bendix issues with the KTMs are a thing as well. You take that out with a screw driver. If they are actual bearings then a blind bearing puller with a chuck that fits in there is the ticket. I'd also use the freeze trick on the new ones for installing.
