Adjusting the preload of the drive pinion bearings
J
– Fit the drive gear (5) into the casing.
8
– Fit the bearing plate (9) with a shim (8) of 0,25 mm to create an axial gap (J) for the drive pinion.
9
– Tighten the screws (10) to 9,5 ± 0,5 daN·m. Note: The value is given for information. – By opening the RH hydraulic cover, pull the pinion, turning it alternately clockwise and anticlockwise in order to properly seat the cones in the cups.
5
– Position a dial gauge at the end of the pinion. – Set the comparator to zero and measure the gap (J). – According to the value measured, select the thickness of the shims "E1" (8) to remove any play and apply a preload "P1" of 0,06 +/- 0,03 mm.

E1 = 0,25 – J – P1. – Check that the drag torque ranges from 0,5 to 2,5 daN·m. – Place the selected thickness of shims "E1" and refit the thrust plate (9) (3 shims maximum). – Fit and tighten the screws (10), coated with Loctite (271), to 9,5 ± 0,5 daN·m.
