Measure clearance between teeth
1 | Fix the support with the magnetic block (1) and the dial gage (2) in the housing. |
Set the gage probe in the pressure flank of one tooth of the ring gear, with a previous tension of 1 mm. |
2 | Measure backlash between teeth of drive pinion and ring gear in four points equally spaced 90 ° apart, and determine the point with smaller clearance. |
Adjust clearance between teeth
3 | Loosen by one notch the threaded ring on the side to which the ring gear should be moved. |
4 | Tighten the opposite ring by the same measure to avoid any alteration to the bearing preload. |
For used ring gear and pinion, maintain the clearance as found before disassembly. |
