 (a)
 Calculate the thickness "N" of the "washer set" as follows: NOTE : The "washer set" includes the washers (63) and the

____

 (b)
 Put the washers (63), the adjustment washers (64) and the journal spacer (65) in position.

 (c)
 Install the journal pin (61) in the fork-end (62).

 (2)
 Install the spacer tube (79) on the lower fork-end (76) of the support arm as follows:

 adjustment washers (64).
 1_ Measure the distance "M" between the fork-end (62),
 2_ Measure the length "P" of the related spacer tube (65),
 3_ Calculate the thickness "N" of the "washer set" (N = M-P) to
 get a clearance of 0.05 mm (0.0019 in.) maximum between the
 spacer tube (65) and the fork-end (62).
 4_ Add the adjustment washers (64) as necessary to make allowance
 for the clearance between the fork-end (65) and the "washer
 sets".

 (a) Calculate the thickness "S" of the "washer set" as follows: NOTE : The "washer set" includes the washers (77) and the
____ adjustment washers (78).
 1 Measure the distance "R" between the fork-end (76),

 2_ Measure the length "T" of the related spacer tube (79),
 3_ Calculate the thickness "S" of the "washer sets" (S = R-T) to
 get a clearance of 0.05 mm (0.0019 in.) maximum between the
 fork-end (76) and the spacer tube (79).
 4_ Add adjustment washers (78) as necessary to make allowance for
 the clearance between the spacer tube (79) and the "washer
 set".

 (b)
 Put the washers (77), the adjustment washers (78) and the spacer tube (79) in position.

 (c)
 Install the journal pin (75) in the fork-end (76).

 (3) Install the traverse (55) on the door attachment fitting (46) of the door as follows:
 (a)
 If removed, install the shouldered bushes (45) on the door attachment fitting (46).

 (b)
 Install the traverse (55) together with the bush (44) on the door attachment fitting (46).

 (c)
 Install the washer (43) and the nut (42) on the traverse (55).

 (d)
 Install the flange (52) on the traverse (55) and attach it with the bolts (57), the washers (56) and the nuts (51) on the structural bracket (46).

 Subtask 52-22-11-820-050
 C. Adjustment of Clearances between the Door and the Support Arm
 (1) Calculate the thickness "U" of the "washer set" as follows: NOTE : The " washer set " includes the bracket (89) and the
____ adjustment washers (66).
 (a)
 Measure the dimension "W" between the fork-end (71).

 (b)
 Measure the thickness "V" of the spacer tube (65).

 (c)
 Calculate the thickness "U" of the "washer set" (U = W-V) to get a lateral clearance of 0.05 mm (0.0019 in.) between the spacer tube (65) and the fork-end (71).

 1EFF : 301-399, 1 52-22-11Page 418 1 1 May 01/04 1 1 1CES 1

 (d) Add the adjustment washers (66) as necessary to make allowance for the clearance between the fork-end (71) and the "washer set".
 (2) Calculate the thickness "X" of the "washer set" as follows: NOTE : The "washer set" includes the bracket (90) and the adjustment
____ washers (80).
 (a)
 Measure the dimension "Z" between the fork-end (85).

 (b)
 Measure the thickness "Y" of the spacer tube (79).

 (c)
 Calculate the thickness "X" of the "washer set" (X = Z-Y) to get a lateral clearance of 0.05 mm (0.0019 in.) between the fork-end

 (85) and the spacer tube (79).

 (d)
 Add the adjustment washers (80) as necessary to make allowance for the clearance between the fork-end (85) and the "washer set".
