GENERAL INFORMATION

Conversion to 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.

Rounding Off

• Converted values are rounded off to the same number of places as the SI unit value. For example, if the SI unit

value is 17.2 and the value after conversion is 37.84, the converted value will be rounded off to 37.8.

Upper and Lower Limits

• When the data indicates upper and lower limits, the converted values are rounded down if the SI unit value is

an upper limit and rounded up if the SI unit value is a lower limit. Therefore, converted values for the same SI
unit value may differ after conversion. For example, consider 2.7 kgf/cm

2

in the following specifications:

210—260 kPa {2.1—2.7 kgf/cm

2

, 30—38 psi}

270—310 kPa {2.7—3.2 kgf/cm

2

, 39—45 psi}

• The actual converted values for 2.7 kgf/cm

2

are 264 kPa and 38.4 psi. In the first specification, 2.7 is used as

an upper limit, so the converted values are rounded down to 260 and 38. In the second specification, 2.7 is
used as a lower limit, so the converted values are rounded up to 270 and 39.

Special Service Tools

• Use special service tools or equivalent when they

are required.

Disassembly

• If the disassembly procedure is complex,

requiring many parts to be disassembled, all parts
should be marked in a place that will not affect
their performance or external appearance and
identified so that reassembly can be performed
easily and efficiently.

Inspection During Removal, Disassembly

• When removed, each part should be carefully

inspected for malfunction, deformation, damage
and other problems.

Arrangement of Parts

• All disassembled parts should be carefully

arranged for reassembly.

• Be sure to separate or otherwise identify the parts

to be replaced from those that will be reused.

GENERAL INFORMATION

Cleaning of Parts

• All parts to be reused should be carefully and

thoroughly cleaned in the appropriate method.

Warning

• Using compressed air can cause dirt and

other particles to fly out causing injury to
the eyes. Wear protective eye wear
whenever using compressed air.

Reassembly

• Standard values, such as torques and certain

adjustments, must be strictly observed in the
reassembly of all parts.

• If removed, the following parts should be replaced

with new ones:

— Oil seals

— Gaskets

— O-rings

— Lockwashers

— Cotter pins

— Nylon nuts

• Depending on location:

— Sealant and gaskets, or both, should be

applied to specified locations. When sealant
is applied, parts should be installed before
sealant hardens to prevent leakage.

— Oil should be applied to the moving

components of parts.

— Specified oil or grease should be applied at

the prescribed locations (such as oil seals)
before reassembly.

Adjustment

• Use suitable gauges and testers when making

adjustments.
