To shift the idler from side to side in order to align
the idler and track properly, you add enough shims (4)
and (5) between bearings (8) and guide plates (6) and
(7) to provide clearance (A) between guide plates (6)
and (7) and the frame (9).
This chapter stresses the importance of your
understanding and following the principles of
front-end alignment and track alignment in vehicle
maintenance. Although these principles will remain
the same, the make and year of the equipment
assigned to your unit will change. Therefore, it is
always recommended that you refer to the manu-
facturers repair manual for specific adjustments for
your particular equipment.
