PERIODIC CHECKS AND ADJUSTMENTS
INTRODUCTION
This chapter includes all information necessary to perform recommended checks and adjust-
ments. If followed, these preventive maintenance procedures will ensure more reliable vehi-
cle operation, a longer service life and reduce the need for costly overhaul work. This
information applies to vehicles already in service as well as to new vehicles that are being
prepared for sale. All service technicians should be familiar with this entire chapter.
