Super baffled by V2 mechbox seizing

[yanhchan]

I just went and upgraded my TM M4 yesterday. And I charged the battery and I went to test fire it today in my room. The mechbox seized up and seemed to only cycle very little I saw the air nozzle move about 2 milimeters. And then my gun comes to a complete stop. I try again and it doesn't even move a bit.

My gun currently has

Systema reinforced gears
Area 100 piston
KA M120 spring
Guarder air nozzle
EG1000 motor
8.4 battery

I think the most probable cause is the EG1000 motor not being able to put out enough torque or it could be due to the spring being too stiff.

I have a theory some how the anti reversal latch is locking things up because mine doens't really sit stright up but it sits more of at an angle and i have to tweek it everytime i close the mechbox.

You might have the Anti-Reversal latch flipped mabey, also check tappet plate.

Spring on Reversal latch too might be an issue.. not much I can say as I only
took apart a V2 a couple times.

Haha I when I first took the baby apart I was thinking...damn I'm going to screw the thing up with something lik eth anti reversal latch. But the dang thing poped out the first time I took it apart so I really have no clue how its suppused to look when its inside. I watched mechbox.com but the angle its shown as didn't really help

[HaZarD SFD]

When you have the reversal latch on right it should have the flat part of the
locking arm facing towards the top of the mechbox... The SPRING should be
set so it puts pressure on the gear and almost wants to jump right out of the
mechbox. Its a bitch to do on any mechbox

Spring should be placed so that it presses the flat side of the latch against the bevel gear.

When you have it apart, press each side of the piston groove into the rail of the matching mechbox side and move it front and back. See if it goes easily or if it binds up. I had to deal with a siezing V2 mechbox (Hurricane) that I installed a Guarder piston in and found the grooves to be slightly tighter on the grooves than normal, so I used a chisel to shave plastic from the insides of the grooves. Worked perfectly after that.

keep the ideas coming I might not be able to get into the box until saturday what with exams and all. Maybe last night was a bad idea afterall haha.

I'm a little worried about the timing of the gears but it seems that I did it properly and I timed it when the Bevel gear was in a locked posistion.

As long as the teeth of the sector gear are well away from the piston when you put the shell back together, it'll be fine.

Ok so I finally got it to work somewhat but it seems to be giving really really low puff of air and also the spring is only going back about 1/2 the distance it should be going. but I'm confused as to which direction the ported cylender should point the port should be at the rear right?

[Renegade)]

Ya the Port should be at the rear because the piston comes backwards, grabs the air and pushes it back.

For some reason the sector gear's teeth keep catching on the trigger and the cylinder.

Is the stub behind the trigger is busted? check to see if its missing
if so u need a new gearbox or u need to makeshift make one

perhaps I'll just shave off a bit off the trigger so things run smoothly. I think I need to buy shims because I lost quite a few in the process of upgrading and is it normal for the back of the tappet plate to bend upwards a bit. Because mine is doing that and I'm suspecting thats the cause of the binding

[yanhchan]

Sitiuation update. The gears will turn in semi and full auto but only without the spring installed. I can tell its working a bit by the action of the tappet plate going back and fourth. However when I install the spring everything just stops. Any ideas???

i don't know if this will help, but check to see if the spring is the length it should be. Last upgrade I did, I had a bum spring that was an inch longer than it should have been. I got the exact same results of firing maybe once, then seizing up. There wasn't physically enough room for the spring compressed to fit in the piston. I ended cutting it back to a tiny bit longer than the stock spring to fix the problem. Later i got a new spring and it worked fine.

It doesn't even work with the stock spring though. Thats what worries me.
