So what is the trick with the DS416M little white Gear?

[truckermusic]

Hi Everyone

Again I find myself rebuilding servos. This time it is the Align DS416M Servo....I am NOT good at this...

I managed to somewhat get the other gears in place but that little white gear I cannot get..

I install it right side up...nope....I install it upside down...nope....I just do not get this and hope some one here can shed some light on what I am doing wrong.....

Also... there is some space between the g4 gear and the others... The last pic is a ref pic of an unmodified one where you can see the space is closer....

Perhaps you have a bent shaft? Or maybe one of the holes, where the little shaft goes, might be deformed due to the impact? Just brainstorming...

Excellent thoughts!
Thank you

I did think of that so I changed the shaft out. However a shaft "can" come bent from the factory so I guess I will just have to explore that as well.

Also from what I can see (but of course now I am half blind and really can be missing something) I can only see One hole where the shaft can go....

But again, I am half blind and can be missing it....so I would not rule this thought out.....I will have to inspect it better tonight when I get ome from work......

Thank you Sir

I haven't worked on the 416s, but it looks like there are two holes like the older align servos. I think the gear is upside down and should be in the other hole. It doesn't look like it is contacting the other gear and looks like it's too close to the side of the servo case. I think I fixed a servo for you before?

Hi Crash
Yes you have fixed servo's for me in the past.......and you have done a WONDERFUL JOB!!!!!

I was so thankful that you did this for me.....Servo rebuilding is just not my forte....I did my DS520 tail servo last night just fine. so it gave me hope to do this one.......but nope.....I have three of them.....

After trying to do the first one and not getting the white gear I opened the second one VERY CAREFULLY....or so I thought...the little white gear came off when I took the lid off....and the same thing happened to the third servo....so now I have 3 serovs with the gear kits and no where to go!

You have to laugh cause i just cannot make this stuff up....

But you are correct....the white gear is NOT touching anything and that is the issue...I cannot figure out how to make it work....that is why I am asking ...

I will look again...

It's the wrong hole. You will notice there is another hole very close with a metal bottom to it. See pic

Don't worry, I made the same mistake as you. Luckily when I opened another servo the white gear stayed put.

[LEORITY]

I think there are two holes very close there. One might be covered with grease. As Crash said, the little white gear seems not touching the other gears and "out" of the case.
Therefore, It is better wipe off the grease from there and check.
When you see the second hole, take a picture and post it here so you might be helping others too
Good luck!

You are correct sir....Just like Crash and Leo...You were all correct!

I found it last night....I tried to get the shaft and the little white gear in position but it kept falling over or out ..... I tried for two hours..... I ended up giving up and putting them all away...

I tried with tweezers, put grease on one end of the shaft to see if I could make it stick in the hole.....I tried to push the shaft in the hole in the top portion of the casing and could not get it......

I tried everything I could think of how to put this together.....I really dislike not being able to get this cause I know that I am doing something wrong......But have no idea what.....

I will try one more time tonight....

thank you everyone for helping me here.

So how do i get the shaft and gear to stay put in that hole?

[zexel]

With the white gear in the approximate location. Try putting the shaft into the hole in the servo case instead, then sliding it all together.

The top case is what holds and lines everything up. Are you holding the servo and trying to assemble it or keeping it flat on a table? Flat on a table works best for me.

Great Suggestion.....Really is ...but I tried that already...I think Tuesday or Wed Night....

The shaft did not want to go into the hole or lets say that "I" could not get it in and stay in the hole...the reason I came up with this thought was because the other two when I took them apart the shaft was already there...so I tried to stick the new white gear on one of thoes shafts and then close it up but there was always a gap left between the top part and the body part...When I tried to move the servo it was locked and would not move......

tried for over an hour...used my fingers, tweezers, plyers etc.....nothing seemed to help...So I had to put it down..

Thanks for trying to help kind sir! This for me is VERY Frustrating...But I still want to fix it....I like these servo's.!

I have tried both ways... but moslty flat on a table....

It seems I have two issues to solve....
1. the white gear which we are trying to solve
2. there is a little space between the bottom of the G4 gear and the next one lower....you can see it in the provided photo's in opening post...

I know that there is a flat spot on the shaft and that the white tab on the gear seems to go opposite of the flat spot...or so it seems that it does...

I have tried to clean the hole out, put a small dab of grease in the hole, and even still it will only go down so far and not more....

And this is what stops the top part of the case from sliding all the way down on to the body of the servo....

So again, I do not know what I am doing wrong...I have taken this gear and shaft apart at least 100 times to try to line it up correctly but it always leaves that little tiny space....

So what are you saying here.....should I put the shaft in the Top portion of the case and slide the white gear on the shaft and THEN put the two halfs together???

Or

Put the shaft and white gear in the hole in the main body and THEN slide the top portion on???

Does it make a difference???
Should I take all the gears off and start by putting the shaft in that hole in the main body, the white gear on next and then place all other gears in position and then close up the servo ????

Cause I did not try it this last way I suggested........but may have to ...been thinking about this........

[CrashNburn420]

I put everything together in the servo and then put the top case on.


If you want me to try feel free sending them to me. Same address as before, if you need it again just pm me.

No no you don't need to disassemble and re build or anything
And don't try to assemble it from the upper case I feel it will make things even more confusing.

The small white plastic gear goes next to the servo motor gear, have the servo infront of you, with the motor facing you.
Right next to the small motor gear, there are two wholes on the right, one would be closer to you, and another further in, next to the bigger metal gear( that is the whole you want to put it in)
its very simple, the white gear has two gears(small one and big one) the small one would need to contact the big metal gear, and the big one will be with the motor gear. Once you have it aligned with the whole, just take a pair of nose pliers and put the shaft in, give it a little push, you'll see that it fits right through, and you would have proper gear mesh.
