ContentsBAS0007D

ALPHABETICAL INDEX is provided at the end of this manual so that you can rapidly find the item and
page you are searching for.

A QUICK REFERENCE INDEX, a black tab (e.g. ) is provided on the first page. You can quickly find
the first page of each section by matching it to the section's black tab.

THE CONTENTS are listed on the first page of each section.

THE TITLE is indicated on the upper portion of each page and shows the part or system.

THE PAGE NUMBER of each section consists of two or three letters which designate the particular sec-
tion and a number (e.g. “BR-5”).

THE SMALL ILLUSTRATIONS show the important steps such as inspection, use of special tools, knacks
of work and hidden or tricky steps which are not shown in the previous large illustrations.
Assembly, inspection and adjustment procedures for the complicated units such as the automatic tran-
saxle or transmission, etc. are presented in a step-by-step format where necessary.Outer Socket Lock Nut : 59 - 78 N·m (6.0 - 8.0 kg-m, 43 - 58 ft-lb)
