g. To adjust the trim travel right, perform the following:
1. Add shim washers at the aft end of the shaft to reduce the trim travel.
2. Remove shim washers at the aft end of the shaft to increase the trim travel.
h. Check the trim and servo travels by swinging the rudder full left with full right trim and full right
rudder with full left trim.
i. Check all travels with specifications given in Table V-I.
j. Determine the free play of the rudder tab with the rudder securely held against either stop. Total
free travel measured at the tab trailing edge must not exceed 0.06 inch. If this tolerance is exceeded,
check the travel control arm assembly for wear at the center bolt and the bolt attaching the rudder
trim rod to the control arm. Replace the arm assembly and associated hardware if there is any
noticeable wear or elongation of the holes. Check the rudder trim barrel end play in the mounting
bracket. Total allowable play is .006 to .008 inches. Use 62833-18 laminated shim stock washer as
required to achieve the correct end play.

4. Re-install hardware ensuring a bushing (P/N 63900-174) is in the flap handle lever bolt hole. If bolt
hole has not previously been enlarged to accommodate the bushing refer to Detail A, Figure 5-13.
