Troubleshooting New Build 2.0: Opinions Requested!

[pestobanana]

Does the sector gear have a circular tappet cam and enlarged release tooth? It's gen1. Gen 1 was harder to shim because the bevels were tall. Even so, they were hard in narrow boxes like VFC but not Lonex.

As for shimming, you say that right now the bevel is shimmed as high as possible, correct? Which pinion are you using now? Also, is there an SHS pinion on right now? Run the motor under no load and check for vibrations. SHS pinions on Lonex motors are a tight fit and sometimes people bend their armatures fitting them.

The cam is circular and the release tooth is bigger. I guess it is gen 1 haha.

The bevel, on the fat side, is as close to the gearbox as it can be (ended up with 1 shim, then no shims just to test, and the motor installed still pushed the bevel gear off its axis).

In regards to the pinion, long story short; I messed up the install on one of my A1's with the SHS pinion and bent the shaft as the pinion would not go on all the way. at that point, I took one of my other A1's and tried it on this build with a stock bevel gear (minor wear & tear). The one installed right now is an A1 with its original pinion.

is there any way to get around the bevel being too high? I'm assuming shaving the fat outer side would bring it lower to the gearbox, but there is room for much error with that I think. Would it be best just to get a lower end set of gears like SHS 13:1 and go from there?

P.S. is there a way to replace the shaft on the motor, or is it junk now?

When you say it pushes the bevel up, how are you testing this? My experience is that bevel gears don't need to be shimmed as high as you might think, make sure the motor is straight and the teeth are aligned. I only had the problem because in my VFC box I could only fit a 0.1mm shim on either side of the bevel, and that was it. I wasn't able to actually shim it. I swapped to Gen2 and got rid of the problem.

If the issue persists and is indeed not high enough, I would say you could try a Siegetek pinion. In my experience they allow you to shim your bevel gear lower, and they mesh absolutely beautifully with Siegetek bevel gears.

I've never tried replacing a shaft, but just get a new armature. I don't like Lonex motors. I liked them when I was just getting into neo motors, but Lonex armatures are garbage anyway, the commutators are just shit. Lonex neo magnets are also shit. If you want to repair your motor, just swap out the armature with the stock VFC armature, the TPA is roughly the same.

Above is how I do my test. Notice the red line is parallel where it should be. The green line is when I have the motor installed and in correspondence to this picture, the left side goes up as the right side is pressed down by the pinion. I would say at a rough 20-25 degree angle. The other side (was) shimmed to properly allow roughly .1-.2 play (obviously increased now with taking shims off the bottom side).

The red circle is the shimming I am talking about. I took all the shims off the bottom (correspond to picture) and it still knocked it off axis.

Higher and lower is difficult without a reference, so use the pic with me.

What are your preferred motors? Tienly?

btw, for moe grips and needing the motor to sit lower, you need to bore out the threads and hole where the motor endbell sits in the adjustment screw. Once you drop 2-3mm of material out, the motor will adjust into the proper range and you can tighten all the grip plate screws.


edit: check the gear axle clearances when the grip is installed.

When you check bevel-pinion shimming you have to do it with the other half of the GB shell. Reason is the motor tower is ALWAYS smaller than the motor hole, so the motor is going to lean in the direction opposite that of the pinion gear. The way you have it set up is so that the motor is leaning in the direction of the pinion gear. That is one of the reasons why your bevel is leaning. With this information its entirely possible that your bevel is actually shimmed too far away from the pinion as opposed to too tightly to it.

As for motors, I use a mix of Tienly, SHS and self assembled motors. I have two guns running Lonex motors simply because I haven't found the time to shim the gearboxes for a different motor.

So I gamed this rifle at Ultimate Airsoft in Toronto this past weekend with the grip change (stock VFC 416 grip) and it fires amazing now. Little to no grind. I will be tinkering to see if I can get the MOE grip grip to work, but as it is working great right now, that wont be fore quite a while.

Thanks for the help gents.
