Keen to see the motor sealing! Good luck!

Quad rebuild started today.
As usual everything took way longer than expected…
It really broke my heart, but I needed to take off the Sabre blades. The extra concave just doesn’t work well with the snowboard bindings.
Besides that I cut myself in the finger, I would say, they came off very well. Definitely can recommend Sikaflex to fix concave pads to the deck.
Maybe I will install them on one of my other decks, but that would mean coloring again.
Funny how small that deck looks without concave pads.
Finding the right mounting position for the bindings was a bit tricky, but I eventually made it after two sets of wrong drilled holes.
Luckily it’s an easy fix with s big if epoxy to fill up the holes.
I did as well print some wedges to minimize the aggressive concave shape if the deck towards the end. Not much needed, just a bit.
I really love those burton step on bindings.
They are just so comfortable.
I probably will add one strap over the boots for the beginning non the less. Bench testing they did very well, but they are made for 8kg snowboards and not 30kg mtb 
so better save than sorry.
Final picture for today. The wires need to be organized, but I will look at it tomorrow.
Might be just me, but with those bindings and boots the board looks soooo small
Lean is 100% better by the way. Definitely good first impression.

Might need to make them a bit bigger in future, but already better than before.

I’m building out that kaly deck for a dude and ge has expressed concern about the shape of the deck. I might see if he wants to hold off on skinning it until he rides it for a bit. Wonder how these would hold up under a skin

I remember a guy waaaay back in 2017 or so made pools of epoxy on the bottom of his deck to fix the enclosure better.
I think that could work on top of the deck as well.
I’m just always a bit concerned about epoxy on flexy decks.

Yeah fuck that. Epoxy is heavy. Dude’s not interested anyway so that was easy

Just got them for my birthday.
Couldn’t try them out yet.

they are the absolute best, would never go back to standard bundings on a snowboard
especially with the convenience of not having to bend down to bind in

I did not have my own snowboard the last years, but I was sure I will get step ons the day I’ll buy my own board. So here we are
To choose the right snowboard I have now all summer

Looks not much different than on the pictures before, but I spent another day of work till this point.
Bindings are fixed
Wiring done and resoldered
46T sprockets installed
Chains cut on size
Big motor rework is next on the list.
Encoders already arrived in Russia, so should be here in a week or two as well.

Loving the progress, dude! Snowboards boots and bindings are serious business. Can’t wait to see some videos on action.

Took me way too long to get the motors off the mounts and open…
I was prepared for a shitty day, but that was a pain really.
Worst part are the small m3 screws on the motor bell which are fixing the holder for the big front bearing… some stupid idiot seem to have glued them in with some kind of loctite…
Took me hours to get them out without to strip them.
guess that idiot with loctite was me, last time I had them apart
Blow torch is an essential tool while taking the motors apart. Never bad to have a pulley puller as well.
Didn’t took much pictures as I was a bit pissed from that work, but still some impression here
And just because it looks nice…
5065 vs 8085
Big front bearings are all changed.
Unfortunately two of the small bearings had been broken as well.
For sure I do not have any 12x21x5mm bearings laying around, so I guess I will need to put this rebuild on hold till I found some new ones.

May i ask what you used to battle harden the stator? looks like sikaflex/silicone but might be epoxy, i can’t tell.

It’s the same epoxy I used for bell as well.

The end caps are finished.
Yes it looks pretty fucked, but it will work how it should.
To cover the big gap between bell end end cap I printed a thin ring.
For the back holes I did as well print some covers
Can’t say I really like the look of the motors now, but if I don’t need to change bearings for the next year or two it’s totally fine for me.
As soon as I had them for one ride they will be dirty anyway, so the look doesn’t really matter that much.

Aren’t you worried about the motors overheating?

Wouldn’t say worried, but I for sure thought about the impact on cooling.
We will see how it goes.
Just in case I choose the right bolts to be able to take the end caps off without need to dismount the whole motor.
Keep in mind that the city I live in is basically just flat. So the hills I will climb are probably not that huge to make the motors sweat.
In winter it will not matter.

The 63100 220kV motors finally arrived.
Disappointing that they haven’t been battle hardened as promised in the product description.
Can just recommend always to take apart a motor before installing it. It’s not a big deal and usually there is something to do inside anyway. (Waterproof hall sensors or fix lose windings etc.)
So I needed to battle harden the motors by my own. I spent one evening running from shop to shop for my favorite epoxy, but it was sold out everywhere…
I eventually found some in stock in one of our big hardware shops but that took me another 20km bike tour to get it.
For sure I bought directly two hands full
As I found some lose windings I decided to do the stator as well.
Not my best work ever, but definitely better than before.
The vesc tool motor detection did calculate those motors for 90A.
That’s a pretty good value.
Better than the 8085s and the 50114 inrunner as well.
Everything is set up now.
On the bench I get a whining noice running them higher than an ERPM of 50 000.
Not sure where that is coming from. Doesn’t seem to affect performance, but definitely isn’t pleasant to listen to.
Will need to check that on a test ride.
Unfortunately it’s just raining today, so it will take a bit till I can get that board back on the road again.
