This guide volition evidence you how to disassemble a TopTech TR16 R4 and its gearbox for the purpose of repair, upgrade, and meliorate understanding of the gearbox functionality.

This teardown is not a repair guide. To repair your GG TR16 R4, use our service manual.

Before disassembling your AEG (Automatic Electric Gun), it is strongly advised to release spring tension to disassemble the gearbox easier.

Before disassembling your AEG (Automatic Electric Gun), it is strongly advised to release spring tension to detach the gearbox easier.
Normally, this would be washed by shooting the gun twice on semi-motorcar, but TopTech AEG's have a spring release in the grade of a frontwards assist. That is more effective.
Press downwardly on the forward help button as shown

This step is for those who wish to remove the front rail system, which is unnecessary for the following steps, but still good to know.

This pace is for those who wish to remove the front end rail system, which is unnecessary for the following steps, but still good to know.
To remove the front rail system, beginning remove the 3mm hex screw on the pinnacle of the rail.
Side by side, pull back on the Delta-Ring every bit shown in the tertiary picture. Remove the lower section of the rails first and and then the upper section of the rail.

Start remove stock safety pad by pinching the tabs on either side of the stock.
Remove the battery mount and the stop cap of the stock.
Printing down on stock adjustment lever and pull the stock off the buffer tube.

In order to remove upper receiver, you lot must first push button out the body pins. (The body pins do not come up all the way out.)
It is recommended to use a punch that is slightly smaller than the body pin. Once the body pin is sticking out half way you should be able to pull it the rest of style past hand.
Exercise non remove the pin completely. The pins are meant to stay attached to the torso body then they wont become lost or autumn out on their own.

You tin can now slide the upper receiver forwards. Information technology may take some pulling to get it to movement.
Attending: Although it is easier to pull the receiver off with the grit cover in the open position, avoid the dust cover colliding with the extended body pin equally shown by the square mark. The open dust cover will prevent yous from moving the receiver forward and could potentially curve the body pins with excessive force.
Afterward this step, the spring and charging handle might autumn off, which is okay.

Now that the upper receiver is off you can now have off the charging handle and spring if they haven't come off already.
Yous can also remove the Hop-upwards unit of measurement and barrel from the upper receiver. For hop-upwardly intermission down you can become to step x of G&Chiliad CM16 Carbine Airsoft Disassembly

With the stock off, await downwardly the Buffer-tube. Yous will run across a large Philips screw which needs to be removed with a long screw driver.
With the screw removed, slide the buffer-tube far enough to expose the wire connectors in betwixt the tube and body of the gun.
Grab the wires on either side of the connectors and pull the connectors apart.

With the wiring connectors separated and the buffer-tube removed, the sling adapter should slide right off.
You can now take off the bolt catch release by taking a thin dial and pushing the pin completely out equally shown. The release should come correct out later the pivot is removed.
Doing so will make it far easier to remove the magazine release.

The Magazine release of TopTech m4's come out just like a real M4 firearm.
Start by pushing the magazine release button into the receiver, so that the take hold of section on the other side of the gun is protruding as far outward as possible.
Then turn the Magazine catch (the long part sticking out) counter-clockwise wile keeping the button stationary, which will unscrew the button from the catch.
Warning: sometimes the button piece can fly off once unscrewed. Slowly ease off the force per unit area to prevent losing the button or the jump.

With magazine catch/release out, you can offset by removing the bottom plate on the grip.
Grab a 2mm Hex driver and begin removing the 2 small screws.
With the Hex screws remove the lesser plate with a prepare of needle-nose pliers

With the bottom plate removed you will see the dorsum of the motor. Unlike other AEG's there is NO small disk to worry nigh.
Catch the the motor connectors with the pliers past their base(where the wire and connector meets) and pull the red then the blackness connectors off the motor contacts.
Next, pull the motor out of the grip either with pliers or a long thin tool.

Unscrew the 2 Philip screws at the lesser of the hand grip.
Information technology is oftentimes easier for re-gather if the screws are left in the grip especially when using non-magnetized tools
Now pull the grip off the wile making sure the connectors exercise not get stuck.

With the grip off grab a sparse dial push the small thin trunk pin out if come across the textured finish of the body pin coming out then you are doing information technology correctly.
The thin body pin needs to come completely out of the gun.
Next push button the large rear body pin to the outward position. This pin is not as hard to push as it'due south forward counter part and can normally be done by hand. Do not endeavour and push it out completely.

Next switch the gun burn down mode to safe if it is non already and brainstorm to button the gearbox out of the receiver.
Y'all may demand to switch the selector back and forth betwixt safe and semi auto to push out the gearbox. The gearbox should be able to exist push slightly forward and then upward out of the receiver.
You tin can catch the from the pinnacle and button the gearbox out from the bottom where the pistol grip was.
With the gearbox out the selector indicator on the right side of the gun should fall right out.

Now remove the the selector link piece by putting a tool underneath long section shown and prying it up.

The next task is to remove the simulated bolt.
Start by removing the C clip as shown. you may demand to use a pick to pry it off.
Subsequently the clip is remove slide the fake bolt all the way back. With the bolt in the rear position press the fake bolt parts that still attached slightly up.
Use a pick to pry the bolt linking section out of the blow back cylinder on both sides.
Conscientious not too bend the fake bolt every bit information technology can impairment its functionality.
Adjacent remove the retaining strap past using a punch in the lilliputian notch shown in Yellow and punch off the retaining strap off the back of the gearbox.

With the retaining strap off you lot can at present apply the same dial on the area shown to remove the blow-back housing.
Afterwords the cylinder slice shown in the second movie can exist simple poled off.
And so pull off the hop up gasket (the green rubber piece) simply so it wont get lost.

Now comes the easy office. Remove the 5 shiny screws shown.
On the sometime TopTech AEG's these screws will exist 2mm Hex and on the new line they volition be standard Philips screws.
Start wit the screws that are at each terminate and piece of work your way to the middle.

With the screws removed take a long sparse screw driver and insert information technology into the dorsum hole of the gearbox. This will prevent parts from shooting out when removing the shell.
You can now us your finger nails and divide both sides of of the gearbox vanquish and pull the superlative half of the gearbox off.
Next remove the spring and spring guide by lift the spring guide upward and out of the gearbox. Then take out the cylinder and connected parts to have access to the gears.

offset pictures shows all the terms for internals to help with future steps. Note Some parts will look a petty different.
At present remove the gears without removing the niggling washers (or shims as at that place called in the airsoft industry). Check to see if there are shims left on the bearings and put them back on the gear it came off of.
Warning: Do no misplace the shims as they have very exact placement within the gearbox.
Shimming or the practice of placing shims on each gear can a complicated and tedious procedure recommend for those with previous airsoft technical feel. Chiliad&Grand AEG Shimming Guide Airsoft guide is avalable if would like to learn this process.
With the gears removed you can at present remove the anti-reversal latch and spring. Careful not to loose the anti-reversal latch bound equally its modest size makes it easy to misplace.

If yous choose you lot can also remove the trigger and wiring.
The trigger tin be poled right out and the switch/wiring harness can be removed by taking out the pocket-size screw but under the trigger.
Congratulations yous have completed taking a TR16 R4 completely apart.
