Mazda Engine SKYACTIV-G 2.5. Manual - part 2

GENERAL INFORMATION 

00-00–2

Service Procedure

Inspection, adjustment

• Inspection and adjustment procedures are 

divided into steps. Important points regarding the 

location and contents of the procedures are 

explained in detail and shown in the illustrations.

Repair procedure

1. Most repair operations begin with an overview illustration. It identifies the components, shows how the parts fit 

together, and describes visual part inspection. However, only removal/installation procedures that need to be 

performed methodically have written instructions.

2. Expendable parts, tightening torques, and symbols for oil, grease, and sealant are shown in the overview 

illustration. In addition, symbols indicating parts requiring the use of special service tools or equivalent are also 

shown.

3. Procedure steps are numbered and the part that is the main point of that procedure is shown in the illustration 

with the corresponding number. Occasionally, there are important points or additional information concerning a 

procedure. Refer to this information when servicing the related part.

UNITS

id000000100400

Conversion From SI Units (Système International d'Unités)

• All numerical values in this manual are based on SI units. Numbers shown in conventional units are converted 

from these values.

Number Of Digits For Converted Values

• The number digits for converted values is the same as the number of significant figures

*1

 of the SI unit.

• For the torque value, the number of significant figures is, in principle, is 2 digits, in consideration of market 

practicalities. However, if the number of decimal places at the upper and lower limits of the converted value 

differs, the one with least number of decimal places is used. In addition, if the integer part is 3 digits or more, 

the integer part becomes the significant number of figures.

*1 : The number of significant figures is the number of digits from the left-most non-zero digit to the right-most digit 

including 0. (Example: 0.12 is 2 digits, 41.0 is 3 digits)

Converted Value Rounding Off And Rounding Up/down

• If there is no tolerance in the SI unit value, after conversion, rounding off is to within the number of significant 

digits.

• If there is tolerance in the SI unit value and the figure after conversion indicates the upper limit, the number of 

digits is rounded down to within the number of significant figures. If it indicates the lower limit, they are rounded 

up to within the number of significant figures.

• Even if the SI unit value is the same, the converted value may differ based on whether that value is the upper or 

lower limit.
