DaktariT Posted September 11, 2022 Posted September 11, 2022 Made a video of my Cyma SVD. All the gears and piston in full working order, I've adjusted the motor height. With the gearbox out of the gun it worked fine but once I put the gun together it starts to sound like it is striping the gears. PXL_20220911_191052172.mp4 PXL_20220911_191052172.mp4
strykerles Posted September 12, 2022 Posted September 12, 2022 May I ask how you fared with the piston?
DaktariT Posted September 12, 2022 Author Posted September 12, 2022 Bought a cyma replacement. Compared the old to the new and the old had no wear on it.
concretesnail Posted September 12, 2022 Posted September 12, 2022 Is the gear box the type which uses a motor cage to hold the motor?

concretesnail Posted September 12, 2022 Posted September 12, 2022 (edited) If the motor is caged and everything runs fine outside of the receiver then I'd be looking for something in the receiver or grip that could be pushing on or twisting the motor inside the cage. Or pushing on the gearbox casing in the areas of the gear axles. If its possible, fit the the gearbox into the receiver and run it withot the pistol grip on. If it runs fine and then fails when the grip is fitted you know where to start looking. Edited September 13, 2022 by concretesnail
DaktariT Posted September 13, 2022 Author Posted September 13, 2022 Cheers for that, somehow a small piece of plastic had got caught under the motor stopping it from dropping down further. Lozart 1
