I love my 36 inch deck
Hi. I have on motor shaft 10mm, and hole on small bore is 8 mm (it have 10 teeth). What to do now? Can I try make bigger hole or buy 10 mm shaft bore? I canât find 10 mm.

10T are too few teeth. It will be hard for the motor to pull that pulley. You should consider a minimum of 15T. So yes, change that pulley for a more swift gear like 15T and Up.

Ok 
and is it fit on my belt? (teeth will be smaller)
I have had the same problem with the 10mm shaft. Almost every pulley has a 8mm hole in it.
You can solve it by drilling a 10mm hole in the pulley (drillpress recommended). Thatâs how I have solved it. But: your pulley, just like mine, is pretty thin. I was lucky enough that the pulley didnât break because the walls around the hole are pretty thin already. If drilling didnât work and the pulley has snapped you can buy another pulley.
The specs you need to consider are:
- Same teeth ratio, so 10 for you I think
- inside bore diameter of 10mm (you can go something bigger like 15mm, because you have to drill the 10mm hole in it by yourself. I am not 100% about that so look that up
)
I hope this has helped you

That is what I afraid it is to thin, but I can tryâŚ
Thanks guys for answers.
i would just buy a whole new pulley
No luck. Itâs broken.
The problem will be because I have to short belt, and if I want install new bore with more teeth it will be larger than last, so I must buy a new belt? I canât find bore with 10mm hole and belt for it in one set. My belt was 10mm width and other bels for sell are 16, 20 mmâŚ

My belt was 265mm. I thinking to buy something like 320mm, 12mm width. Is 12 mm belt enough to pull 65kg uphill without broken?
depends which belts you buy
lol his belts wonât breakâŚ
Iâve done 800-1000 km on 9 mm belts until they broke! This was on flat pavement and steep hills, so 12 mm belts are just fine.

Hi. One of my battery all 3 cells stop charging at 3.71v.
Is that because I charge them without âballance chargeâ? So, how to return it to start charging 4.2v, do I must discharg them and charge again but this time in ballance charge?
Yes balance charge. Why didnât you every time?
Youâre probably going to have to make a small pin connector to the balance lead for just the low cell and charge at 1a for that individual cell.
Thatâs if itâs not ruined. If you took that battery and ride with it that one cell will now over discharge compared too the charged cells
I connect it with small pin with cable for ballance, but i not set in charger ballance mode.
I yesterday try first time charging and forget set that option.
I now discharging, that will help?
No it will not. You will discharge the low cell below a safe voltage
Omg :-o âŚ
