You checked the backlash measurement before pulling it apart so you can reset it. . . . ..

I actually wasnt able to as I misplaced my magnetic base... I think my gf kids snagged it and left it somewhere :banghead:

I have resetup used gears before without having to much gear wine before so I'll be crossing my fingers with this set too. :prayer:
