Very informative, thank you for the videos, I am curious how to switch the small gear on the motor shaft that connects to the large gear inside the gearbox. Is that small gear called a pinion? When looking at the replacement motors online they don't see to have that small gear they are just a round shaft.
You need to heat is up with a lighter and pull it off its a press fit; then press it on to the new motor. Remember there is a plastic washer behind the gear so not to much heat.
What is the rpm of these 775 motors? I look on ebay and they are only 9000 rpm at 24v. Bought them and they run very slow. Even at 24v the 775 motor i bought run maybe 3 mph max.
I want to put two 350w motors in my sons police car but I knew these gearboxes were cheap. It would be nice to find aftermarket boxes with all metal gears
The way the torque is distributed through the gears; only this gear needs to be metal and the rest hold up great after the torque is reduced through the gear set.
If I apply 18v to a stock motor, would that be problematic? I.e swapping a 6V stock battery to an 18V Milwaukee drill battery? I ask because I see all these videos on YT where guys are just swapping the battery, but won’t that just burn out the motor? Thanks, great videos btw!
you sound native american in the beginning. Overvolting a 12v motor to 24v will be faster than running a 24v motor at 24v. Since your new motor is bigger it will have more torque even with less volts but the speed won't be as fast.
The kids are going to enjoy riding.

@@daveprototype6079 thank you!
I watched other videos of these things they are pretty wild how you can modify them :D
I was pretty surprised to see that the stock motor spun so much faster. ......but as you mentioned...that's free load speeds.
sweet MOD! your channel has my support!
Thanks
How can I tell which side on the motor is positive and negative if it is not labeled?
They are DC motors
once you hook them up they will either go forward or backwards; check with the controls hooked up

I am not sure of the RPM's as this project was quite some time ago. I do mention that the OEM motors were much faster but also more $$$$

Thanks i learned a lot my kids will be happy thanks again
awsome
SORRY off subject but What happened to the press frame built.
That project got completed; I just didn't see a lot of interest in it on line. I can do a video on it and all the attachments I made for it

There should be no issue with the motor; my mods were to 24v.
is there no problem with this higher voltage for the electronics ? like the remote control ?
Me gustaría saber mejor de la información pero en español si se puede x q no se inglés y gracias x compartir la información
It would be nice if the 1st &2nd gears were both steel
yes; they are made to wear out

Hi iam about to order those motor
But should I use 18v or 24 v
both are good choices; let your budget guide you
Jimmie Stewart lol 😂
LOL
Throw a bigger battery on it.
What do you mean bigger??
Throw a full size car battery on it. More speed more power!!! He He He He!
