As you can see in the Predator Gasser NX manual, on page 36, the hub that the crown gear is attached to, is pinned solidly to the mainshaft using a pin that is held on center by two grub screws on each end. This means the gear mesh between the pinion and crown gear is directly related to the vertical location of the mainshaft and the horizontal location of the front drive pinion. I am sure you will find the answer by insuring that both of these items are in their proper position. If there is no up/down play in your mainshaft installation, then I would suspect the poor mesh is a result of an improper installation of the pinion gear assembly into the front transmission.
