Rebuilding A Crashed Sherman

[@Dustendee]

Glad your friend is okay! And wow! What a come up!! 1 free Sherman 🤙🏼

[@rustambogdanov8935]

True EUC enthusiast test: if that video was joy to watch, then you are. For me it was like a good movie, pure joy to watch, with plot twists and sense of humour. Excellent job and video. Thanks, Marty!

[@ElectricUnicycles]

Glad you enjoyed it!

[@euc_sharkman]

Great video Marty! Glad to hear your friend turned out ok from what sounded like a crazy crash. As still a newcomer to EUCs, this was extremely fascinating and a primer to understanding the core pieces of a EUC. That roll bar isn’t just for show. The difference from potentially being totaled to a near perfect restoration. Well done!

[@manuelsanudoguerreira7319]

Fantastic diagnosys and restoration,Marty. The mere thought of going thru all that with my Veteran just gives me shivers but you make it look so easy. Congrats on your new well earned Sherman despite the sad circumstances:After all, your friend is fine. Beautiful rosso corsa paint ,too! Now you own a one wheel Ferrari 😍

[@ElectricUnicycles]

Thanks :-)

[@euc-mercielago]

What a coincidence, I just crashed my veteran at 45mph . I’m amazed how tough this wheel is. The wheel rolled about 100 feet and with every flip it broke a different part of the headlight and sending debris flying up which made for a spectacular sight. I don’t speed unless I’m the only person on the trail so no one was at risk of being hurt. My protective gear saved me except for small cuts on my fingers (fingerless wrist guard) and a small scrape on my elbow (elbow guard moved during impact). I’m glad you made this video because it helped ease some anxiety about taking it apart.

[@ElectricUnicycles]

Glad you're OK. How much damage did yours suffer?

[@euc-mercielago]

@@ElectricUnicycles Thanks! I could probably get away with just the complete roll cage and front headlight. But, if I need to take it apart I’ll replace the motor/rim/pedal hangers with the wider rim because I had dented the rim going up a sharp curb in another incident. Edit: Forgot to mention that the current rim is cracked not just dented but still holding air. Im not sure I can install the rim to the motor so that’s why I’m getting the motor w/ rim combo.

[@ElectricUnicycles]

@@euc-mercielago Ah, so it sounds like a good time for a major maintenance job. It's fundamentally not hard, just take your time. Good luck.

[@andyq9898]

this video turned out better than i thought. almost like watching a perfect movie with suspense and a beautiful outcome.

[@duluncheyilai]

You've got loads of handy tools and patience to boot. Well done for such a fantastic video. Wishing your pal a speedy recovery.

[@GGnext.crazycro]

Just a small warning when it comes to paint. Some paints can have metal particles like the silver or gold paints making the paint slightly conductive. Something to think about when you spray the electronics enclosure (the paint can even chip away due to vibrations some times).

[@GGnext.crazycro]

P.S. That red looks gorgeous! 😍

[@WILSONsHobbies]

nice, this is the only video i could find about taking off the shell. It will be helpful when replacing the shell on mine when its time lol

[@mikeintampa250]

Happy holidays Marty. Excuse the pun, but I was glued to my phone watching this, lol. You have more patience than an ER doctor. I don't even own a Sherman and I was completely interested and entertained. Now my phone battery is near death and I won't be able to be interrupted by phone calls today. It was so cool watching you meticulously dissect the Sherman, diagnose the various problems, and then correct them. You even found ways to improve it. Bravo!

[@ElectricUnicycles]

Thanks Mike :-)

[@ElectricUnicycles]

Thanks 👍

[@WheelersPro]

You can connect the batteries to the motherboard slowly, it is a connector XT90 anti-spark (with the green lines). There is a resistor at the beginning of the connector which limits the charging current of the capacitors and when pressed down this resistor is shorted

[@ElectricUnicycles]

Good to know - thanks. I still like to stay with the "habit" of connecting them quickly.

[@bubukis]

@@ElectricUnicycles "Quickly" is not a right thing to do for this type of connector. When you connect it quickly - you just short the integrated resistor immediately, so the whole purpose of it is neglected: you still get a surge of over-current from the battery damaging it every time you connect this type of connector "quickly". While if you connect it first just up to a green line, wait a little bit (before the capacitors charge slowly through the integrated resistor), and only then connect it all the way to the end - there is no surge of current and your battery remains healthy...

[@ElectricUnicycles]

@@bubukis This Sherman does not have anti-spark connectors (there is no integrated resistor)

[@OliGerard]

It was very fun to see you replacing the ventilation grids. 😜

[@ElectricUnicycles]

[@ElectricUnicycles]

Nice

[@Juansan76]

So sorry for your friend! 😮 I hope he recovers quickly. 🙏🏾 On another note....you lucky bastard lol! A free SHERMAN!! What!? Who says that?! So awesome for you brother 🙌 enjoy! I'm looking at purchasing one (Sherman) but was thinking about waiting till they come with suspension model as well. Wish we got more insight as to what was coming down the pipe. Anyways, thanks for posting these!

[@ElectricUnicycles]

Yeah, what Veteran releases next is a total mystery. If you do get a Sherman you'll love it. Tons of local riders to me have the Sherman.

[@alexelmagnifico]

Absolutely beautiful wheel. I really enjoyed this video Marty. Awesome job! 👏👏👏👏❤️❤️

[@ElectricUnicycles]

Thank you so much 👍

[@Andre-Mostert]

Nice to have a look inside the Sherman but its a faff to get everything back together again. Those batteries are proper slabs and looks really well package. But as you say they could really give you a fully assembled main board. The red and black looks awesome "red baron" and I think those new pads is going to finish it off nicely. Thanks for sharing.

[@ElectricUnicycles]

Thanks. My new pads are arriving shortly and then this red Sherman will be complete :-)

[@PaulA-pm3gx]

Have had drivers at a stop sign, look directly in my direction but still fail to see me with a high visibility fluorescent vest on. Really need gloves to protect fingers. Have had a crash with impact to ankle and hip. Need to have motorcycle boots on to protect the ankles. Damage to ankles can mean permanent disability and not being able to walk ever again. Very complicated joint, hard to perform successful surgery on. Have shin guards on hips to give some protection from impact. Full protective gear is essential. Great vid, look forward to the next one, thanks.

[@ElectricUnicycles]

Personally, if I don't have "eye contact" with a driver I won't ride in front of their vehicle. Thanks for the comment :-)

[@Monarhh369]

Today I got a short circuit on the charging port of Sherman Max due to the metal charging port cover (was a very bad idea to upgrade the charging port covers). Now Sherman Max is not switching off and not balancing. On the motherboard blue and red lights are blinking. If unplug the batteries it will switch off in a few seconds, but after connecting the batteries back: the same issue (not switching off and not balancing). The wheel does not recognize the charger (no feedback from the wheel on both ports). The motor rotates by hand normally without any additional noise or resistance. Do you know what blinking blue and red lights on the motherboard mean? Should I replace the motherboard or there is an easier solution?

[@daley1985]

Nice video,did u do any waterproofing when u reassembled it? Looked like a silicone bead when u first split the original case?

[@ElectricUnicycles]

You are correct. From the factory they install a tiny rubber gasket that goes around the perimeter. Unfortunately they don't supply a replacement with the new shell. Since it rarely rains where I live and when it does I don't ride, I didn't bother attempting to add any weather sealing.

[@001NorthWind]

[@ElectricUnicycles]

The symptoms were not identical (flashing headlamp). The yellow transformer was broken and one of the capacitors was damaged.

[@omidel.]

What tipe of screws does the sherman uses on the rollcage? Please

[@ElectricUnicycles]

Wood screws. And no, I didn't reinstall them. I don't see the point and they weren't there on the original Sherman.

[@omidel.]

@@ElectricUnicycles you have my respect. Thank you

[@Fantaman900]

I own a sherman too after my RS got lost in shipping. Its a blast ridding it around but i am not happy about the factory using a straight valve stem with a slight bend put in. I have to take out the wheel before I can do tyre pressure. Not looking forward to take apart my new wheel to swap inner tube to a 90 valve stemmed one

[@PaulA-pm3gx]

Maybe try using a valve extender that screws on when you need to check/pump up the tyre. Makes it easier than trying to attach the air compressor hose directly on to the valve.

[@Fantaman900]

@@PaulA-pm3gx Oh went and checked the wheel again on there is a hole in the middle where I could possibly sneak in a 90 extender. So thanks for the tip

[@smallratt]

hi Marty, did you see something like sudden acceleration on gotway msp hs? mine is brand new and I am really upset, because it's my first euc, it accelerating until cutout even if i try to brake it :/ I am lucky that i didn't step on wheel, only tried freespin

[@ElectricUnicycles]

I'm confused by your statement. You haven't ridden the wheel? Are you talking about lifting the wheel and it starts accelerating?

[@smallratt]

@@ElectricUnicycles yes, I've video on my channel, in air when i slightly tilt the wheel to accelerate it goes until cutout (60,5mph) and i can't brake it, really strange behavior, i can't find almost nothing about this case on whole internet, only found some teslas have similar problem with sudden unintended acceleration

[@ElectricUnicycles]

@@smallratt This is normal behavior and nothing to be concerned about. It's impossible when you are actually standing on the wheel. Literally impossible. When you are a bit more experienced you'll know how to lift the wheel and let it accelerate or slow it down as desired.

[@smallratt]

@@ElectricUnicycles it can't be normal, acceleration is sudden until cutout, not smoothly, even if i want hold it in one position wheel goes up to cutout, i don't know how to explain it better, sorry for my bad English, i know it only from movies, TV shows and your videos :D

[@smallratt]

so even when speed limit is preset in euc world app for example on 20, on freespin wheel goes up to cutout?

[@ullle66]

The fact that you dont get a complete installed motherboard is pretty ridiculous. Securing the Mosfets with heat transfering glue and so on is one of the most important things to do , shouldnt be done by end customer. But good job, Marty! The “stand alone” transformer (yellow) isnt related to charging. Its the 5V (or12 here?) transformer, responsible for lights, and board control power.

[@ElectricUnicycles]

Thanks. Good info about the transformer - probably explains the flashing lights. Fortunately the transformer isn't important to the functioning of the balancing logic/power.

[@0xeb-]

Nice restoration. I like the colors for sure. Curious how much eWheels would have charged to fix it for you.

[@ElectricUnicycles]

They would have charged the same for the parts ($650) plus labor. Probably at least $1000.

I didn't realize this but I've been told that the Sherman actually does use anti-spark connectors on the batteries.

[@timwatterson8060]

@@ElectricUnicycles the connector with the green section on it is an anti spark connector, pop a multimeter on the green contact, and it has a resistor on it. EDIT: going slow on the insert is actually better with this connector hobbyking.com/en_us/xt90-s-anti-spark-connector-2pairs-bag.html

Hey Marty, could you explain the, "Always Turn On the wheel AFTER Disconnecting the battery"... And WHY so? My obvious question is: How does the wheel even Turn On if its not even connected to a Battery??

The capacitor holds a little bit of charge so you want to be sure to drain that after disconnecting the power before you do anything further.
