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/cm2 in the following specifications: 210—260 kPa {2.1—2.7 kgf/cm2, 30—38 psi} 270—310 kPa {2.7—3.2 kgf/cm2, 39—45 psi} • The actual converted values for 2.7 kgf/cm2 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 End Of Sie 00–00–5 GENERAL INFORMATION FUNDAMENTAL PROCEDURES CHU000000004A01 Preparation of Tools and Measuring Equipment • Be sure that all necessary tools and measuring equipment are available before starting any work CHU0014W003 Special Service Tools • Use special service tools or equivalent when they are required 49 SE01 310 WGIWXX0024E 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 WGIWXX0027E Inspection During Removal, Disassembly • When removed, each part should be carefully inspected for malfunction, deformation, damage and other problems WGIWXX0028E 00–00–6 GENERAL INFORMATION 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 00–00 WGIWXX0029E 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 WGIWXX0030E 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 — Lock washers — Cotter pins — Nylon nuts WGIWXX0031E • 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 CHU0014W006 00–00–7 GENERAL INFORMATION Adjustment • Use suitable gauges and testers when making adjustments CHU0014W005 Rubber Parts and Tubing • Prevent gasoline or oil from getting on rubber parts or tubing WGIWXX0034E Hose Clamps • When reinstalling, position the hose clamp in the original location on the hose and squeeze the clamp lightly with large pliers to ensure a good fit WGIWXX0035E Torque Formulas • When using a torque wrench-SST or equivalent combination, the written torque must be recalculated due to the extra length that the SST or equivalent adds to the torque wrench Recalculate the torque by using the following formulas Choose the formula that applies to you SST 1 Torque Unit N·m kgf·m kgf·cm ft·lbf in·lbf Formula N·m × [L/(L+A)] kgf·m × [L/(L+A)] kgf·cm × [L/(L+A)] ft·lbf × [L/(L+A)] in·lbf × [L/(L+A)] A : The
