Examine the Back-To-Back measure
Using a calibrated gauge, check that the back-to-
back measurement is within tolerance at the top and
bottompositions of the wheels, record findings on table 1.
Note! This can only be measured with the machine sitting
on the rails.
If back-to-back dimension is out of tolerance adjust with
shims.
Examine axial/radial play
Turn the trolley upside down. Clean the entire wheel
flange and tread, removing,grease, corrosion and debris.
Rotate the wheel and check that there is no sign of axial
or radial play in the bearings, or noises or harshness.
If axial or radial play in the bearing exceeds 0,05 mm, or
noise or harshness is detected, dismantle and replace
the bearings and rectify the defects. Note! This work
must be carried out in a workshop.
Examine wear
Rotate the wheel slowly by hand, and examine all
surfaces of the wheel, checking for cracks, cavities,
metal migration and flats.The acceptable limits for all
wheel parameters are found in, Wheel Examine Record
Form.
Replace worn wheels in pairs or re-profile in pairs.
NOTE!
If flat is more than 30 mm, remove from service
immediately. If flat is 20-30 mm, remove from service on
completion of work.
Examine the wheel profile
Usa a profile gauge Fig 109. Profile template” to check
that the wheel profile is within limit Fig 110.
