Removal of Parts
- While correcting a problem, also try to determine its cause. Begin work only after first learning which parts and subassemblies must be removed and disassembled for replacement or repair. After removing the part, plug all holes and ports to prevent foreign material from entering.
Scheme 18
- If the disassembly procedure is complex requiring many parts to be disassembled, all parts should be disassembled in a way that will not affect their performance or external appearance and identifies so reassembly can be performed easily and efficiently.
Scheme 19
- When removed, each part should be carefully inspected for malfunctioning, deformation, damage and other problems.
Scheme 20
- 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.
Scheme 21
- 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.
Scheme 22
- Standard values, such as torques and certain adjustments, must be strictly observed in the reassembly of all parts. If removed, these parts should be replaced with new ones: Oil seals Gaskets O-rings Lockwashers Cotter pins Nylon nuts
Depending on location
Scheme 23
- Sealant and gaskets, or both, should be applied to specified locations. When sealant is applied, parts should be installed before sealant hardens to prevent leaks.
- 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.
Scheme 24
- Use suitable gauges and testers when making adjustments.
Scheme 25
- Prevent gasoline or oil from getting on rubber parts or tubing.
Scheme 26
- 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.
Scheme 27
- When using a torque wrench - SST combination, the written torque must be recalculated due to the extra length that the SST adds to the torque wrench. Recalculate the torque by using the following formulas. Choose the formula that applies to you. TORQUE FORMULAS Torque Unit Formula N.m N.m x [L/(L+A)] kgf.m kgf.m x [L/(L+A)] kgf.cm kgf.cm x [L/(L+A)] ft.lbf ft.lbf x [L/(L+A)] in.lbf in.lbf x [L/(L+A)] (1) A: The length of the SST past the torque wrench drive. (2) L: The length of the torque wrench.
Scheme 28
- When using a vise, put protective plates in the jaws of the vise to prevent damage to parts.
