Checking the bevel gear mesh

Once the two outer flanges and the distributor have been fitted, check the gear mesh carefully as follows: With a sharp pin, check the outer gear surface as shown in the figure, to ensure the surfaces are at the same level in the lapping zone.

To check mesh, rotate the gears to see if there is any play or interference. For the most efficient operation, there should be no play or interference.

If play or interference is evident, adjust the thickness washers above and below the central upper conical gear. In this manner, you can correct the mesh of the three gears in the upper group.
