A Check friction torque of tapered roller bearings of ring gear
Only check friction torque when 'pinion housing with drive pinion' is removed.
1 Mount torque meter (2) with the shop-made tool (3) in the cutout of the shaft.
Is located on the open side of the threaded ring (1).
2 Turn ring gear continuously by at least three revolutions and read off the friction torque in the process
3 Compare value read off with the specified value.
W33.30-0037-01
B Check friction torque of tapered roller bearing of drive pinion
Check friction torque only when radial sealing rings are removed.
1 Slide connector flange (5) on splines of drive pinion.
2 Install bracket (2) on coupling flange (5).
3 Tighten collar nut (1) with the specified torque, use socket (4) and ratio wrench (3).
4 Remove retaining wrench (2) from connector flange (5).
W33.30-0038-01
5 Mount torque meter (6) with socket (4) on collar nut.
6 Continue to turn the coupling flange using the torque wrench (6) by at least three turns and read off the friction torque in the process.
Friction torque < specified value insert thinner spacer washer.
Friction torque > specified value insert thicker spacer washer.
Aim for lower specified value for run-in tapered roller bearings and upper specified value for new tapered roller bearings.
7 Detach coupling flange again.
