Finally we have found out that the cause of 2nd gear stripping problem was in the rear urethane belt and not in the 2nd spur gears itself or whatever.
In order to solve this problem, you just need to replace the rear belt from urethane (T0266) to rubber belt (T0269).

no offense, but i dont buy that post, been using urethane front and rear and rubber on side and had any issues, just like tom b, did the same and also kept and eye on how the engine shaft moves, since a front engine bearing with too much wear can also affect the stripping issue
