TOYOTA PREVIA 91-97 REPAIR MANUAL

GENERAL INFORMATION AND MAINTENANCE 1-

Fig. 30 Some specifications require the use of a torque angle
meter (mechanical protractor)

tightened, a predetermined seating torque and standard torque wrench are

usually used first to remove any compliance from the joint. The fastener is

then tightened the specified additional portion of a turn measured in

degrees. A torque angle gauge (mechanical protractor) is used for these

applications.

Standard and Metric Measurements

» See Figure 31

Throughout this manual, specifications are given to help you determine

the condition of various components on your vehicle, or to assist you in

their installation. Some of the most common measurements include length

(in. or cm/mm), torque (ft. Ibs., inch Ibs. or Nm) and pressure (psi, in. Hg,

kPa or mm Hg). In most cases, we strive to provide the proper measure-

ment as determined by the manufacturer's engineers.

Though, in some cases, that value may not be conveniently measured with

what is available in your toolbox. Luckily, many of the measuring devices

which are available today will have two scales so the Standard or Metric mea-

surements may easily be taken. If any of the various measuring tools which are

available to you do not contain the same scale as listed in the specifications,

use the accompanying conversion factors to determine the proper value.
