The only video on the internet that actually helps me to understand how to shim my gears! Thank you so much!

@teddyho2708 10 лет назад

Thanks. One of the shimming videos that makes sense without any guesswork on the height of each gears. Can't wait to test my hand

@AirsoftingTutorials 12 лет назад

Thanks for your input. The hole drilled does not affect the gearbox structural strength in any way not does it effect the gears, this technique is used by quite a few people to ensure that the pinion to bevel gear alignment is correct. I would link but comments do not allow it. Your right the cut-off was never even installed, I actually forgot to film it and never got around to re-doing it, i'll put up a caption when I get time.

GREAT JOB ON SHIMMING.!!!!!!!!!!!!!!! I was use wrong way to shim my gears. thanks a lot.!

@AirsoftingTutorials 11 лет назад

Its an ACSU V2 trigger unit, those thin wires are the data wires that connect it to the main unit, and determine burst, single shot, ab etc

@airsoftwwbde 12 лет назад

I love your videos! They are the best Tutorials about Airsoft on RU-vid. I just cant understand why then have not mutch more views O.o

@npickart 11 лет назад

No. First you want to put a small shim on each gear so it doesn't contact the case. Then you want to look at each pair of gears to make sure they mesh together well. You may need to add another shim or two so there is optimal teeth to teeth contact. If you don't do this. You just wasted time and will blow out your gears.

@AirsoftingTutorials 11 лет назад

With a version three the motor is usually in a cage, Just attach it to one side of the gearbox with the bevel gear in place and then adjust with the screw at the end of the motor cage until it is in the right place.

@ZaCkOX900 12 лет назад

I just think you should drill a hole at a different location which would still do the same peeping but also allow the pistol grip to be installed. I do no guessing when shimming. Also to point out the body can create a problem for motor height pinion shimming. No bushings or bearings are glued down or stated to do so. I have done a lot of different brand installing and seen many shimming problems that are not stated online.

@korrytv 3 года назад

Thank you helped a lot

@AirsoftingTutorials 11 лет назад

Thanks, i think you mean 0.15mm not 1.5mm as thats a massive gap!! For the gears to spin there will always be a small gap enough for grease. I like to give them a max of 0.05mm play, personal preference. Thanks for the comment. AT

@AirsoftingTutorials 11 лет назад

Its simple when you know how. To simplify it: 1. Shim each gear individually to the gearbox 2. Shim the bevel to the motor 3. Shim the spur to bevel 4. Shim the sector to the spur 5. Place all the gears in add a small amount of grease to the bushings and test. Thanks AT

@davidvalentino8811 4 года назад

thankyou, best tutorial for shimming. i have question on bevel to motor step, my bevel and my motor is too tight even without any shim on the wide suface side, do you have any suggestion?

@AirsoftingTutorials 11 лет назад

It could be a few a things: Quality of the gears The gearbox itself If you try each individually and they make no noise i may just be the gears and you may not be able to do much. Try adding a small amount of grease to the teeth and axels of all the gears as well as the bushings, it may just be the metal on metal contact. A few of my gears especially in cheaper gearboxes make a small amount of grinding noise but once its all assembled you cant really tell.

@AirsoftingTutorials 12 лет назад

Hi, thanks, is nice to know people appreciate them. The videos have not been up long, about a month now so views are a little on the low side.

@jeffchung35 11 лет назад

you dont need to drill a hole in the gearbox. you can just screw the pistol grip on the other half of the gearbox shell with the bevel gear and find the correct motor height.

@griffin_silbert 3 года назад

Thank you, this helped so much.

@supersmashbrosevil 4 года назад

Very well explained, however I think it's easier to attach the grip to one half of the gearbox to see the motor height, no need to drill

@AirsoftingTutorials 12 лет назад

If you shim the gears correctly the tappet plate should not really be an issue, I have never had the tappet plate tight between the gearbox shell and the sector gear before so I didn't know to include it in the video for shimming. I usually check this when I do a pre-build to make sure everything is in the correct place and functioning properly. However i think that that your point is a good one and should be checked when shimming.

@hakont.4960 11 лет назад

An automotive parts or hardware store should have a decent selection of various lubricants. Pure silicone grease is good for air seal parts, while lithium or molybdenum grease is good for mechanical parts like the gears.

@AirsoftingTutorials 12 лет назад

That trigger is an ASCU V2 trigger it's about £60 to buy, there are lots of videos on youtube about it. I could do one on installing it, but it is very easy to do and probably not worth it.

@Skribuliss 12 лет назад

But will you make more awsome vids like these? And if yes then what will be the next one? :) Thumbs up!

@DarkShooper 11 лет назад

I use a quick release clamp to simulate the gearbox being screwed together, less time unscrewing

@AirsoftingTutorials 12 лет назад

More videos will be coming when i get around to it, should have some more up before christmas. For the next video i am not exactly sure what i will be doing yet but there will be more than a few videos uploaded.

@CarsFitnessMoney 11 лет назад

I wouldn't say there should be no vertical movement. 1.5 mm of movement so lube can make its through. Other wise I think its a great video!

@Skribuliss 12 лет назад

will you make a tutorial how to make that electronic trigger?

@TheReviewScientist 11 лет назад

Should you put the same amount of shims on each side of the gears?

@up2wind81 10 лет назад

Great video. But is there a double job? Why not skip straight to phrase 2? Are you using ASCU? Noticed there is no cut off lever. And also, if you are using Spectre, more likely you are to shim sector gear 1st (to contact the cut off switch detector) and work your way to the bevel gear.

@Tek_777 7 лет назад

up2wind81 that's actually false. I have shimmed several gearboxes with btc fets and I ALWAYS start with the bevel to pinion. It is wrong to do otherwise as it can cause poor shimming or unnecessary wear on other parts. The way to shim a build with a btc fet is to shim bevel to pinion and if and ONLY IF the sector doesn't touch the cutoff switch, take a shim off the bottom and put it on the top. I have never had any issues with a sector not contacting the switch anyway. You have to shim pretty high for it occur.

@Nicomonnn 5 лет назад

rip i have an ares amoeba am016 with new AOLS 16;1 gears and cant get a good configuration, i got the gears to sping freely and quiet with the gearbox open but once i close it the gears are tight as fuck

@jeffchung35 12 лет назад

make a video on gearbox lubricants

@Docv400 6 лет назад

You don't need any Shims on the 'small' end of the Bevel Gear. The Motor Pinion Gear keeps the Bevel Gear tight against the Shims on the other end, so it can't physically move to the left. You need to shim the Bevel to mate correctly with the Pinion.

@Bammo956 11 лет назад

how can i adjust motor height? ive got a v3 and i cant see the pinion gear through the shell

@skin_wizard 5 лет назад

What kind of V.2 GB is this? I've never seen one so reinforced!

@balinttoth356 5 лет назад

i think it is the gg gearbox!

@CloseIy 11 лет назад

Where can you guy grease locally that work's good?

@minzy102 9 лет назад

I've got two guns that I've built. Both with SHS 14:1 gears, and SHS contacts. I've found that my semi flickers between semi and auto. It's the contact trolley/shuttle that the cut off lever sear has been worn down a lot so semi doesn't work. This is my 3rd set of SHS contacts. Is there a better alternative?

@bleepinfireman 9 лет назад

+James Minzy I just put a metal pin in the trolley, it hasnt broken since then

@grahamwilliams2494 9 лет назад

What mosfet is that? A btc chimera mk1?

@rianryl1015 9 лет назад

when I finish shimming and assembled my gun. I tried shooting but the gears lock up and leaves the piston cranked but not pulled all the way to the back nor release to complete the cycle. if i keep pulling the trigger it makes a buzzing sound without any gear spinning.

@HereticEngaged 9 лет назад

Your motor is probably in too high or has too much contact with your bevel gear. Shim via the bevel to pinion method and start off shimming the rest from there.

@rianryl1015 9 лет назад

hi HereticEngaged yes. Right after i posted this comment i adjusted my motor. It was too high. I realized when i was adjusting the motor height while the gearbox was open is different than when it is actually fired. THANK YOU.

@jeffchung35 11 лет назад

please make more videos

@AirsoftingTutorials 11 лет назад

Not sure probably gen. 2, cant remember really, no problems so far though.

@brandongoad1692 11 лет назад

what generation?

@Zurin 7 лет назад

Great video

@ZaCkOX900 12 лет назад

The other videos are good but this one missed more than a few important points. Also the drilled hole is a bad spot. I would NEVER recommend to drill the hole there. Cut-off was never even installed. No tappet plate was checked either.

@jeffchung35 11 лет назад

show a video of how the gun sounds

@Gattobuono 10 лет назад

Interesting and useful video thanks, but I could do without the really annoying repetitive 'music'.

@filipin1771 7 лет назад

Excelente!

@brandongoad1692 11 лет назад

those gears are shs 16:1 aren't they

@douglasflores70 6 лет назад

can you share the schema of the trigger>

@AirsoftingTutorials 11 лет назад

04:35 they are 13:1 shs gears

@AirsoftingTutorials 12 лет назад

On my to do list...

@JackJackPGH412 10 лет назад

Is this done on a V2 or V3 Gearbox? If its a V2 what trigger assy' is that?

@nitemunky76 10 лет назад

@AirsoftingTutorials 11 лет назад

No problem

@josiahs9559 8 лет назад

on average how many bearings will I need

@aznaurkasumov4104 8 лет назад

You mean shims? Its not the same in every gun so you will have to take your time and figure it out yourself :)

@Jvha761 7 лет назад

Fleek Geek Usually one shim set has done the job for me.

@Bammo956 11 лет назад

THANK YOU SO MUCH!!! :_)

@hieunguyen3783 4 года назад

2 ! can you help me

@giuseppedamaro7222 6 лет назад

Si inizia sempre dal centrale!

@dogg755 10 лет назад

few shims as possible under the gears, majority on top.

@skatzre 9 лет назад

nope

@dogg755 9 лет назад

wanna explain?

@skatzre 9 лет назад

The bevel to pinion meshing would be incorrect if you shim the spur as low as possible. The biggest transfer of energy occurs between the bevel and the pinion gear, so if that was not shimmed properly, your gun would have incorrect meshing.

@skatzre 9 лет назад

Commonly in VFC guns, when replacing the auto shimming gears with normal gears, the majority of the shims are on the bottom, with one or two on the top. That is because if there were more on the top, the bevel would be pushing onto the pinion and grinding. Source: airsoft tech and has owned 4 VFCs and worked on countless others. Same with JG. I cannot speak for other guns except G&P, BUT i ASSUME it would be the same due to the size of the bevel.
