modify gears shreading my piston

Trader rating · April 2nd, 2008, 17:59

I bought a set of modify torque gears that come pre assembled and there is no need for shimming. I instaled it in a v3 gearbox with a brand new modify polycarb piston. I am useing a m120 ish spring. It worked well for about 100 rds then the first 9 plastic piston tooth all shreaded right out. It shreaded the right side of all the teeths. Should I be useing a half tooth piston? I tought those we only for helical gears? Why has it failed so fast?

I used modify gears in my TM M4A1 with a Prometheus MS110SP spring and the rest stock. I had no such issues. They worked extremely well until the front end broke off my mechbox (unrelated to gears). I just sold 2 sets of them last week, one to LyquidFyre who's already installed them in his AUG and are performing flawlessly there too.

Could it be perhaps that the piston wasn't installed in its rails properly?

Look at the sector gear, if the teeth that mesh with the piston are the same if not very close to the same diameter as the teeth that mesh with the spur gear, you need a half tooth piston.
You sector gear usually only meshes on the right side of the piston depending on how you shimmed the gear anyway.
How fast is your gun firing?
And TM pistons are actually really high quality pistons lol
