Hi guys. I have received a V2 gearbox from a friend who left his RIF out of action for a while and when he returned the gun no longer fired.
I took the gearbox apart to take a look and the grease has solidified partially which I thought could be the issue.
I have completely stripped the gearbox, and cleaned all gears etc so no grease or grease build up at all, also cleaned piston etc and replace grease in necessary places.
When the gearbox is open, all of the gears move freely and are placed correctly. All wiring has also been tested and working as it ahould to power motor from the firing switch.
When I tried to fire the gearbox. I can hear the motor turning what must be about 1mm before it hits the 1st gear but then everything is just rock solid and the motor cannot turn the gears. The battery and connectors then get rather hot due to the motor being frozen.
I have tried the motor and tested it in another RIF and it is working perfectly. Does anybody have any idea why the gearbox has frozen?
I have also been able to turn the gears manually with a screwdriver and the piston and spring seems to be working correctly. I just don't know why the motor cannot make the gears turn.
