1 | Using the threaded ring adjusting wrench (1), unscrew the ring (2) until having some axial play on bearings |
The tightening should be gradual so that the ring does not press the bearing (cap and taper) after the crown touches the pinion. |
2 | Gradually tighten the ring (3) until eliminating the backlash of the hypoid gear pair (backlash zero) |

3 | Measure distance between pedestals of bearing caps (diagonals A1 and A2) using a suitable micrometer, and write down values |
These measured values will be the benchmark to adjust the expansion of the bearing caps while adjusting the bearings preload. |

4 | Release the ring (3) until the original gear play is achieved, and gradually tighten the ring (2) to allow the preload of the bearings and, consequently, the expansion of the bearing caps to the prescribed dimension. |
Take the measurements as the ring (2) is tightened, thus ensuring that the desired expansion is achieved. |
