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.

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.

Rubber Parts and Tubing

• Prevent gasoline or oil from getting on rubber 

parts or tubing.

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.

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.

A : The length of the SST  past the torque wrench drive.
L : The length of the torque wrench.

Vise

• When using a vise, put protective plates in the 

jaws of the vise to prevent damage to parts.

Inspection

• When a tester is used to inspect for continuity or 

measuring voltage, insert the tester probe from 
the wiring harness side.

• Inspect the terminals of waterproof connectors
