I've been combing that forum to no avail.

There isn't really a disassembly guide per se. Tackleberry took some pics of the problem areas and that's about it.

There is no need to tear the motor down for cleaning. There is nothing to clean. If you have arc damage to the commutator, it must be turned on a lathe and the brushes replaced with higher silver content brushes, which is all new ones.

I don't know about you, but I have a bunch of magnetic chips stuck to the magnets which I want to get out.

I've never had such a big problem trying to locate guides for airsoft gun's. I don't understand why its always either "send tac this or only tac knows how to do that". (or any other retailer for the matter)

Its not rocket science so why does everyone insist on sending simple parts across the pond just to get a little work done???

Because its not that simple to do
As well, why would Tac give away a guide on how to do it when he makes his living working on them and doing the mods. If it had a simple guide, do you think members with many years experience on PTW's would hand over their motors for tac and the select few docs to do?

I can tell you that I have torn apart probably a hundred PTW motors. I also turn a screwdriver for a living and have many years of working with tools and my hands. Removing the magnets from a PTW motor is not something you are going to learn from a guide. You simply have to do it. For those who wanted to know, I showed them how to do it.

It is not rocket science. But if you haven't figured out how to do it, no online guide is going to help you. You need the correct tools and strength.

It is really as simple as that.

BTW, you can remove the metal shards all you want an they will be back in the beofre you get the grip on.

I've got everything apart except for the two magnets.

So I could ask myself, is it as simple as prying them apart since theres nothing holding them in but the magnets?

I don't know, I could get the halves off as much as I'd like but before I do so I just wanted to find a second opinion. (SHOW ME WHERE TO BUY JUST THE MAGNETS WITHOUT REPLACING THE MOTOR)

You said yourself that you've done so many times in the past but yet you had to grief me over the fact that its nothing you can learn from a guide but yet people could pick it up if you'd just "shown" em.

The PTW motor is a naked motor. Normally on a encased motor, the magnets are not something you worry about since they are usually permanently affixed to the housing. SO out the comm and whatnot, but since the PTW has a PITA design, how wrong am I to find out more before I could potentially make a mistake.

Once you have removed all 8 screws (yes, there are 8) which hold the brush hood set in place as well as the bell ends, it is simply a matter of force and leverage. Alot of force.

Use a quality screwdriver and pry like a bastard, hoping your screwdriver doesn't break. I use 3 different sizes. You must also mark the polarity of the magnets relative to each other and the brush hoods. If you get that wrong, your motor will not turn and you will kill your electronics.

I learned to do it on my own, after nearly 20 years of electrical and electronics experience, and an interprovincial ticket as an electrician who actually works with electric motors. It is simple, if you know what you are doing. If you have to ask, you do not know what you are doing, and therefore shouldn't be doing it.

I could have been a dick and left out the polarity bit, and you would have found out the hard way, as there is no way to measure polarity, it is relative, and the magnets are not marked.

Your mistake is attempting to take the motor apart in the first place. It is unnecessary. But go ahead if you insist.

You Sir, have made history.

This will be the first post in all of interweb history that actually details somewhat; the dis-assembly process of the PTW motor.

Thank you again Mcguyver! I knew there were more screws than the nylon ones and you've confirmed that for me.

I salute you :salute:
