If you have the original gearbox note the shims on the pinion and center housing shaft, normally with new gears it will be close. First step is to shim the pinion in and out, with the goal of the teeth in contact with the inner 2/3 of the gear, using grease on the gear to make this easy to see. It's not easy because you will constantly have to pull the housing on and off. Next the backlash needs to be .16-.2mm, this is achieved by shimming the cast housing up and down as needed. I would also check it after its ran under load for 8hrs, hope this helps.
How did you set the backlash on the pinion gear?
