Nice work ACD! The motor install really isn't as complicated as you make it sound. But you did bring up some points that everyone will need to address installing the Nichibo.

Here's my install I originally posted. All I needed to do was grind the screw post as shown here a bit:

Then reposition the electrical connector out of the way that you see in this photo:

The motor fit right into perfect position for me (I've done this twice with two of my mags).

I think if you dont do this, you need to do some plastic grinding to get the larger nichibo motor to fit inside. As well, the motor shaft axle pin whatever you wanna call it the part that spins lol is much longer on the upgrade motor. I thought you would have to cut it down to size, but its better you dont in case you bungle things up like I did at late night.

No need to cut the shaft. Also I would NOT recommend heating the output shaft to set your pinion gear. Heating the shaft could melt the output shaft's plastic bearing just inside the casing.

Best thing to do is drill out the pinion gear's hole to just slightly smaller than the Nichibo's shaft and press the gear onto the shaft. I did this a 1/4" socket as the press tool (I actually tapped the gear on this way with a small hammer). Mine are pressed on firmly enough that if I tried to hold the gear in my fingers and start the motor, it might take the skin off my fingers before it could slip!

A very good point about the polarity. I know very well what I am doing with my mags

By the way, I havent had to adjust the clutch on mine whatsoever....it works like a champ!!!
No pun intended

I don't recommend you mess with the clutch (that part with the friction plate and spring/adjustment nut). Unless you really know what it does and how to adjust it. If you tighten it too much, you will put too much strain on the motor, too little and it will not feed bb's efficiently.

The clutch is there to "save" the motor. When the bb feed is full, the motor should still spin the gears until the "timing" is done. It really isn't "rocket science". Although, it needs to be tight enough to feed, but slippy enough to allow the motor to spin when the feed is "full". Do NOT lube it! I'd suggest you leave it be.

Yaaa I wouldn't recommend it either. Theres no real change happening with that side of things anyways. It worked before, should work after.
But both ACD and I had binding issues after the Nichibo motor was installed.
I would suggest messing around with how you mounted the new motor if your having troubles...rather than messing with that clutch.

but at $50 a bottle, i'll just stick with my contact cements and epoxies, lol

It just took a washer...for some reason...reason still unknown, wedged between the inner side wall and the motor to have no issues with the sprockets binding as they were before...very weird..neways it worked for both mine and ACD...so who knows??
I think actually ACD is correct in that its keeping tight up to the next sprocket with no slip room. Maybe these motors work well under pressure!!!
No pun intended

Its Called "The Last Glue"
I found it at one of those booths at a bike show. I never usually buy things from those silly stands, but this guy and his Crazy glue intrigued me a little. Well its been a few yrs now, and i still have some.
It also came with this "pixie dust" called The Last Fill...it basically gets sprinkled over the glue if you need to repair holes, cracks, re-bond....and it dries instantly.
You can sand it, paint etc...
I must admit, it was pricey..50 bucks. But the value was there. I prob wont need to buy anymore for a while still. Im sure i would have spent that easily in stupid tubes of crazy glue that barely even works.
The trick to "The Last Glue" and bonding things is the less you use the better. And the area needs to be clean but somewhat roughened up.

Cam, send me an email in a pm, i will take mine apart...(for the 100th time) and take some pics, send them to you tonight to help out anyone else who wants to do it and has no access to a dremel. I do, but I like to keep everything the "way" it was.

Its pretty easy to drill and tap the motor holes to re-align the connectors closer to the edge inside the mag and the outer edge.
I also found that, this way, when putting the mag back together, it was much easier to get the screw that tightens the mag together back in.
The Nichibo motor is "fatter" than the stock motor, so the more room you have, and no wire to obstruct your path....the easier the mag is to get back together.

Yep! Up til about 2:30 in the morning, three of us, blasting away at Shoot'N'C targets! His wife was upstairs sleeping, she was all groggy heard the shooting, but in lala land, so we didnt get in trouble! Hehehe

I had a chance to check out JimC's handiwork in terms of his barrels and sleeve covers, they are SO nicely made! WOW. I know what my Drozd is getting next, now that my Nichibo is installed finally! I need HPA and mix and match barrel kits... ASAP! OR next spring, whichever comes first.

And I FQ$%!(!@ it up royally the install haha, I keep grinding down the motor shaft too much, less and less, and even less, thank god DrozdDave bought 9 extra motors!

But thankfully, he stepped in, on his grinder in his workshop and straightened things out, with some crazy insane glue with some sprinkle magic pixie dust.. dont ask.. or if you do, ask Drozd Dave! Some $50 space glue astronauts use in space or something technically advanced like that lol... anyways, got my gear wheel placed back on and the magic dust filled in the cracks and the glue to harden it all like expoxy and so far so good... will let you know if I have any problems in the future but it seems to be aligned just fine right now.

Also added a spacer using a washer above the motor, just to angle it slightly more towards the gear teeth so it bites deeper or better. Without the washer added, the clutch was going off or seizing. It seems adding a small washer just above the motor to give it some angle support, fixed everything up in both of our blackbird magazines, in both our mods. Just seems to work better for some reason, and also with the gear wheel pressed down much lower on the shaft.

DrozdDave as well, pretapped the screw holes for me in the Nichibo, and reorienting it by 90 degrees rotation, so the two solder pins, or motor contacts that stick out basically clear the screw housings in the magazine frame assembly.

I think if you dont do this, you need to do

Wow! So much since my last post!

I know its a long thread, so reply is a little late and sounding off topic, but I am a chronic pain warrior just like many of you.

Messed up lower back/spine brings me much grief and torment on the daily.. Every day is like bipolar madness of dr. jekyl/mr. hide.. Pain, no pain, pain, no pain.

It really is hard on the body, the back and forth. I second that pain meds are really bad for you, but I would not be standing or in a humane mood without them. Sucks to be a slave to big pharma, but worse to be in pain 24/7.

Its hard existence, and I just wish there was more permanent relief. Seems like every pill is just a countdown timer until you dont feel well again. The meds help, but only short term, and they hook you and your wallet for life.

I wish they could solve the root problem instead of just taking care of the symptoms (pain) but as radical and green dots know, lower back or sciatic type pain is the worst. I couldnt stand for a week a few weeks ago, you question whether life is worth living or to take yourself out... and to normal people, yes this just sounds insane, but to repeat the cycle over and over daily, really is a marathon for you to deal with. Problem is, it never ends.. I just wish it would. When you have something make you question whether it is worth living or not, well, I guess for most here, you dont know what that is like, but for other people suffering, you know exactly what Im talking about. Feel bad for others in pain, I know winter and the cold/wet makes me more stiff, muscle tension, and pain, so I hope you all can adjust to the crazy weather swings we experience here in north america.

Sorry, got kinda long and rantish - just know that you arent alone, others feel your pain with much empathy and sympathy and you always got a good core group of forum members here to give support and advice if you really need it.

On another note, replying to all your dre

Jimc barrels arrived on Monday, forgot to post cus ive been soo busy with it!!! They really make the drozd look like a death machine now. Did the tactical setup, but i bought the mix and match kit, so i may try smg tonight after work...
A little bit pissed that the guys i had install my new reg on my new tank, they were supposed to fill it too...my dad picked it up for me or i would have noticed.
Who in their right mind would give back a hpa bottle to a client empty??
I dunno, but to me it seems pretty retarded.

That Nichibo motor is rated for 9v to 30v, it can take it all, and it can take it all day. The hardest part of finding a good match is the speed. The stock motor is rated for 4000rpm @ 12v. The Nichibo is rated to do 4930rpm @ 12v, so it's about 20% more speed which is about as close as you could get.

Question, may have been answered already...I dont really understand what switching between 15 and 24 volts does? Is it only there so that you dont blow your board if you use larger battery power?? is there any real change when using either setting?
I'm just wondering cause my batteries are near dead, and im waiting for new life PO4 batts and a charger...

If you have a stock motor in your BB mag, you want to keep it on the lower voltage connection. Since you now have the Nichibo motor, go ahead and put it to the full voltage connection. The lower voltage setting limits voltage you choose (up to 24v) to 15v to the motor so that high voltage will not burn out the stock motor. The "full output" setting puts whatever voltage you are using to the motor as well.

Makes sense. I added an internal switch connected to the 3 jumper positions, and used the right side switch on the gun to control the modes...15 or 24.
I guess i just made it easier to go from stock mag to upgraded motor mags in an easy switch out, not to mention the rpm switch works again, as the voltage switch. Makes me feel better from taking it apart and drilling and cutting into it...lol :biggrin:

Not like I will be changing back to a stock mag, but it was a fun mod to add.

drozddave, i have about 10-15 perfect Crosman 760 barrels if you are interesting in doing the work to put one on your Drozd. Some are rifled as well as smooth. LMK. Glad to help if I can.

I do have some ordered from JimC. They are lost in the mail right now. Thanks though!!
