@marksmith Hi there, thanks for sharing the details. I’ve checked your case in our system, and we may also need a photo of the motor shaft so we can confirm whether it’s damaged or broken. Please upload it through your support ticket and keep us updated there. Thanks!

I uploaded the requested pictures. The motor shaft did not break on mine. But, the small pulley is a bit chewed up from the belt wires cutting into it. The motor turns freely and I can hear it start up if I reconnect the blower module and turn it on via the app. Hopefully a new belt will return it to proper functioning. As long as it doesn’t just shred another belt.

Did anyone try to use this belt and see if the unit will run?
My S1 suffered the disintegrating timing belt this morning while clearing 3” of snow. Ticket opened #151849 @Yarbo-Forum
So sorry to hear this. Snap some photos of the motor gear pulley too and attach to your support ticket. That way if there’s damage they can send a new one of those too.

I did. I tried to add them here, but the IOS interface doesn’t seem to offer access to additional photos when editing a post.

Ouch. Really sorry to see the broken timing belt!! How long did you have this snowblower module before the failure?
Hopefully Yarbo will send you a replacement shortly, and hopefully this will be the only belt failure you are forced to experience!
Hi all. Just updating on my case. I received my new S1 module today (they overnighted it from California, I’m in New York), just in time for another snow dump. I am back in business, things run fine. I noted it’s the same light-grey timing belt, which is also the same as the replacement belt they initially sent. Hope it doesn’t have issues. I also see it’s the same slight redesign on the main gear that mike.birch had.
Thanks everyone and @Yarbo-Forum for their help!

Put this in service the week before Christmas. I have used it 3 times.
Upon further investigation while removing the remnants of the belt from the drive pulley, it would appear that the wall of the drive pulley closest to the motor is deformed and actually seperating from the body of the pulley. The last strand of steel belt is wedged in the crack between the pulley wall and pulley main body. This raises the question of what failed first? Was it a batch of bad belts or is it a batch of poor qc pulleys? Either way, my machine will need both. At least I have my plow blade to push snow while this gets resolved.
Let’s hope it’s just the belts. Looks like you may need both parts now, unfortunately
Is that a spacer or something? I would think the pulley would be all 1 piece, slid onto the shaft and secured with a locking nut, maybe a steel sleeve if the pulley is aluminum to prevent internal striping of the aluminum pulley keyway
Have you experienced any issues with the belt? If so, please feel free to contact our support team, and we’ll be happy to help arrange a replacement if needed.

Please remind me of the spray I should apply. I’m preparing for a heavy snow and forgot what was recommend. Also thinking I should pick up a replacement belt at the auto parts store as a backup
This post should help.

Be surprised if you can get a belt at an auto parts store. The belt they use is for computer driven Iran’s like 3D printers etc. I got mine from Amazon so I had one on hand just in case. Haven’t needed it. Yet. 
Auto part stores in my area didn’t carry a compatible belt. I got one from GPR industrial for $8~.
Mine chewed up the belt. Less than 3 uses on my driveway and expected first significant snow fall coming in 36 hours! Hope support responds quick.
Yarbo really needs to improve on their customer support communication.
3 1/2 days ago was the last response on my ticket, wherein John stated:
"My sincerest apologies for the inconvenience. I am ready to initiate a replacement for your Snow Blower’s belt and pulley. To proceed, could you please confirm your complete and exact delivery address?
Once I receive your confirmation, I will process the replacement request right away.
Thank you for your cooperation.
Kind regards,
John
Team Yarbo"
I immediatley confirmed my delivery address. Total silence ever since. I posted on the ticket 23 hours ago asking about the status, hoping for a tracking number. Nothing.
When Manny SnowMower works, it is awesome. My neighbors watch in fascination when it has been in use; people driving by on the street slow down, some even stop and back up to watch it clear the driveway. When it works properly, it makes my mobility impaired life better/easier, which is why I invested in Yarbo.
My concern and uneasiness about the equipment and company overall keep growing; I have repeatedly experienced no sense of urgency from customer support when I have had issues. In this instance, with only a couple of hours use, the belt and pulley shouldn’t have failed; someone somewhere dropped the ball on quality control. Add to this the fact that in the little over a month that I have owned this thing, I have spent the majority of the time waiting for something mission critical to arrive from Yarbo (the battery, shear pins, now a pulley and belt). All of my uneasiness is due to lack of clear, concise, transparent communication from Yarbo.
In this case, based on the message from John, I expected an acknowledgement of recieving my confirmed shipping address and a tracking number within 24 hours.
NOTE: If something is out of stock/back ordered, please tell me.
I really hope that Yarbo can get their customer support communication reformed, so customers with open support issues are not left sitting for days wondering what is happening.
