Difficult to say if it will be ok. It all depends on how well you did it.
Its a bit iffy though to say the least. On something as critical, i would not even use a helicoil. A time-sert would be much safer and more secure. I have used these for repairing cylinder head stud holes in bike engines and an M10 will take 50 N/m no problem.

which idler? The bottom one doesn't have much load and ought to be fine. Given then you've already gone to M12 you don't have many options in terms of thread repair. Both Helicoils and Time-serts are a sort of thread repair systems. They both involve drilling out the original thread, tapping a new slightly larger thread, in the case of the helicoil, threading in a spring type insert, while the Time Sert uses a solid insert with both external and internal threads.

If you've already put the m12 thread in, I would leave it as is. You may be able to get an EZ-lock insert to fit straight in, that's another solid style thread repair insert, and it uses normal thread sizes rather than a proprietry thread. There might be an m12 to m10 repair insert from EZ-lock.
