Checking friction torque of tapered roller bearings

1

Install the lock key (5) in the actuation flange (2) and tighten the collar nut .


Tighten the collar nut up to the prescribed torque and do not use any pneumatic wrench for its tightening.



2

Install the torque meter (4) with the adapter of the socket wrench (3) in the collar nut.



3

Turn manually the torque meter at least three turns, and check simultaneously the reading of the friction moment.


Should the friction torque is higher or smaller than the prescribed amount, disassemble again the pinion again and fit a compensation washer as necessary. Repeat the operation as from step 1, until the specified value is obtained.


For axlesHL8 the adjustment washer thickness is supplied as from 1.60 mm with increments of 0.05 mm.


In axles with used bearings, a friction moment value close to the smallest prescribed value can be found, as the bearing has already seated. For axles with new bearings, a friction moment value close to the highest prescribed value can be found, as the bearing has yet to seat.



4

Lock the collar nut .
