    My own Dewalt 14.4 Instal. LOTS OF PICS

    I did some searching around when I sat down to start this install... I was looking for some tips and pictures of things I should be doing. I couldn't find much, especially in the way of pics. I found enough info to get it done but I figured id take my own set of pics as I went and post up a step by step how to... might be helpful for those looking to do the same upgrade. I did NOT install caps on the motor... Im not sure if I should have... I can always go back and do it later if someone could suggest a proper cap to use. I had also previously installed 5mm castle bullets on my truck, thats why your seeing them installed. The process would obviously be the same if you were using stock wires. Here we go:

    +++As always, click the pics for a MUCH larger version in Photobucket+++

    Heres a shot of the motor. I bought the new 14.4 volt motor. The number stamped on it is 396505-21...


    The next step is to solder your power wires onto the brushes. To do this you must first remove the brushes from the motor. I had to go online to figure out how to do this and found a helpful video on youtube. Bascially, you just slide the entire brush structure and plastic hold out as one piece. Just put a flat screwdriver in the little gap at the motor shaft end of the brush and holder and pry it out. It slides out very easily. Be careful when as it releases from the motor as its under spring pressure and will pop out.


    Heres a shot of the whole brush unit... very slick and easy to use system. Spring and everything is all in one piece.


    Next you need to tin the brush end and install the wires. You'll see the section of the brush that would typically have a flat connector attached from the drill... I chose to attach my motor wires to that area. Remember to use flux and remember you don't need a GLOB of solder...


    When you done with both sides you simply slide the brushes back into the motor housing. They can really only go in one way from what I can tell. When your done... the motor should look like this:

    Heres a few comparison shots of the Titan 775 and the Dewalt 14.4. Most would do this first... but not me. I save it for the middle.


    Next is to remove the pinion. Im sure there are many ways to do this... the one I read about and liked was to cut the pinion off in a width wise cut... across the top of the pinion and taking off a small section of the shaft also. This does 2 things... first, it removes the pinion and 2nd, it cuts a flat spot on the shaft... all at the same time. Once I got the pinion cut all the way through I used a flat blade screwdriver to pry the 2 halves off the shaft in 2 pieces.


    O.K.... now we need to think about mounting the motor. This is the most annoying part. The holes on the dewalt motor can are just SLIGHTLY farther apart than the holes on the 775... so you need to widen the holes on your motor mount. I did this with a metal drill bit... I just pushed the drill bit sideways against the hole where you want it to be wider... kind of like a CNC bit. But WAY more ghetto. Heres how the holes look when they're done:


    Once you get the holes widened on the mount and the motor will bolt up... you just install it like you would the stock one. I went back to using 14/68 gearing because the Dewalt motor is physically larger than the 775 by a tiny bit and I really don't think I could have got it to fit with the 12/58 gearing I was running before. I didn't need any spacers or shims or anything...

    Heres an overhead shot of the install when its done. This shot also shows the batteries installed. I cut the fins out of the rear battery vents so my battery wires now come through there instead of the little openings on the battery doors. I also installed a balance lead extension and mounted my LVA beside the ESC. Overall this is a pretty slick install I think. What do you think?

    The pinion is a Novak 14t... Im not going for speed... just cool temps and LOTS of torque. If this motor has the power I think it does I will likely go up to a 15 or 16t but it all depends.

    I have the LVA hooked up to the BEC side of the ESC... in my case it was the one with the red tag on it... but it might be different for others. Not sure.

    I ask about which side it's hooked up to(LVA) 'cause according to what I read the green lite is supposed to blink when you connect the batt on the BEC side, I've done it with both batt's independently and do not see any light blink, what mine does is that when i connect the left batt and press the "set" button on the ESC the system will power up for a few seconds (lights, receiver led, servos come on) and when right side is connected nothing happens, so I'm unsure which side is the BEC side.

    Rotarynut... the BEC side is the side that allows the system to power up for a second. The other side does nothing... When they say "makes the light blink" they mean it makes the system come on, but not stay on. So you've found it and your doing it right...

    Thanks YZmoto... just figured it could help someone so its nice to know it might.

    Cool, I just wasn't quite sure. the Dewalt mod will be done on mine in a no so distant future, have you run yours yet?
