Reassembly

REASSEMBLY

Replace all packings and O-rings with new ones. Apply engine oil to the frictional surfaces of the functional parts.







Key point of reassembly

(10) Seal rings
Position the spindle, valve and bushing in the body. Install the seal rings on the spindle.

NOTE: Make sure that the different seal rings are installed alternately.







(9) Body
Apply a vacuum pressure of 86.6 to 93.3 kPa {650 to 700 mmHg, 25.59 to 27.56 inHg} to the power chamber with the valve fully closed. Check to ensure that the clearance between the body and valve is in the specified range indicated in the table below. If it is not, adjust the stopper bolt and tighten the lock nut.







T : 5 - 7 Nm {0.5 - 0.7 kgf-m, 3.6 - 5.1 ft-lbf}












(3) Clevis
Install the clevis on the push rod, and connect the lever using a pin. Adjust the position of the clevis so that the push rod can be set in position when pushed 2 mm (0.08 in) against the power chamber. Check that clearances A and B between the valve and body are equal and that the push rod makes contact with the stopper bolt on the "full-open" side. If no contact is made, adjust it as in key point (9).
