ok, i lit it with a flame for a very long time, and tried to take off the pinion, but it didnt work. so i placed the pinion onto the stove and turned it on. i left it for a very long time. it become super hot. i tried to pry it off again. it didnt work. i took a - screw driver and tried to take it off. nothing. for 30 minutes i tried to take it off. then, in an angry asian rage, i took a hammer and smashed the heck out of the motor.

That is why the special puller is worth every penny.

This is why a hobby vise is so good to have. Well worth the $40 or so at Sears. It also works extemely well for putting pinions back onto motors. Even better than the C Clamp I was using.

WHY!?

anyway you only need a butane torch. or you could have left the soldering iron on it overnight and in the morning it would have been hot. i havent tried this yet but i might

It shouldn't take that long to heat up unless your soldering iron is crap. Either way, I wouldn't leave it sitting overnight, unless you enjoy burning your house down... :p

ugh i just tried taking the pinion off the stock motor and had no success. i had my soldering iron cranked to 85w and still had no success. I just broke down and bought the pinion puller from horizonhobby.com

Awesome, do I know you? you sound familiar

Any tutorials on how to do this spinbrush motor mod??

BLING POLISHED SPINBRUSH MOTOR!!!!:D

After I failed using the soldering iron heat up and pull the pinion off method, I bought a pinion puller from horizonhobby.com

I suggest if you're going to take on this mod, pick one up. However, please read on before you make your decision.

Microspeed stated that the motor might be faster than a Stage 2 if the wheels would stop spinning. I disagree with this statement. My dad ran his S2 drift motor right along side of mine with the spinbrush and the S2 top end was a bit higher. I could already tell before he even ran his. I'm using hard treads on back and stocks on front with AWD and I did not have the problem with getting traction on my tile floor. Even the basement floor wasn't too bad. It eventually hooks up there too. I definitely agree about the torque. It has quite a bit of power. I was able to control drifts with much more ease than the S2 drift motor. I really didnt notice any difference in the loudness of the motor either. It was just as loud if not a little more quiet than the S2 running with it.

As far as a tutorial....get the pinion puller and save yourself a ton of frustration. You just have to take wire cutters and pull the motor shaft out enough to be able to get the pinion puller frame between the pinion and the motor. Then just simply tighten the screw and watch the pinion slip off with ease. I then put the pinion on the spinbrush with my craftsmen hobby vise. Very very easy. Don't forget to file the motor case down where your solder points are. This gives the solder a better contact surface to stick to. As far as soldering goes, just get the solder at RS with the flux in it unless you prefer the other more difficult method.

No I'm talking about a tutorial on how to do the mod itself.

It's that first step that I am trying to eliminate, but haven't found a way yet. When you use the diagonal cutters, it doesn't move the pinion, it moves the little brass spacer on the armature inside the motor can. That causes two problems:

1. The spacer can end up in the windings, where it can cause a short, or worse, make it impossible to remove a couple of turns without rewinding the whole motor, as the wire gets stuck on that spacer.

2. You get excessive play on the armature, which can cause the brushes to not run where they are intended to run, making for an inconsistent performing motor, or worse, a dead one, if the armature shifts too far and damages the brushes.

I wish they didn't put the pinions on so far. :mad:

What mod are you referring to exactly. I thought I pretty much covered it.

Yeah I knew it wasn't good for the motor to pull out the shaft but it was the stock one so I didnt care about saving it.

I don't care about the S1 motor I am taking the pinion from but, is there anything I need to know about placing the pinion on the spin brush motor? I don't want to ruin that. Do I have to lubricate the armature or anything like that to get the pinion on? I wouldn't think I'd use a hammer to knock it on. I don't want to come off as stupid, but I want to do this tomorrow, and am even going to my LHS to try and get a slot car pinion gear, so I can avoid the whole mess of pulling the pinion from the current motor.

Thanks! :D

nah i just set the pinion on the new motor by hand and then use a hobby vise or C clamp to do the rest.

Ohhhhh, so you laid the pinion on a little then stuck the motor with the pinion side one of face of the vise and then the other parte of the endbell on the other face?? Good thinking.

Speaking of hobby clamps, I wish I knew who made mine cuz it is sweet! It has a small compass so that you can angle the entire clamp, you just loosen it, put it at the angle and clamp it down again. Great for if you need to drill something at an angle or take the hack saw to something.
