Disassembly of Canted Yoke Actuators
Canted yoke actuators are disassembled the same way as the symmetric yoke actuators
except for the following additional instructions for specific models:
(Models 023-100)
These actuators are disassembled using the same procedure as the symmetric actuators.
However, the thrust pin (9) is removed from the housing (1) via access plugs on the upper
and lower housing mounting flanges.

Remove the pointer (16), pointer adaptor (13) and pry out the thrust plate seal
(12) (if fitted).
Remove the thrust plate (13b) and thrust washers (22) from the output shaft (3).
Position the yoke (2) in the fully clockwise position (viewed from the thrust plate
(13b) side).
Using a soft hammer, drive output shaft (3) out through the thrust plate side of the
housing (1). This will drive out the upper output shaft bushing (5) and yoke key (6b).
Remove the piston rod bushings (7) from the housing (1).
Shift the yoke (2) around in the housing (1) so that the thrust pin (9) and roller
bearing (10) assembly can be moved out of the yoke slot. Remove the thrust pin
retaining rings (11) and withdraw the roller bearings (10), thrust pin (9), piston rod
(4) and yoke (2).
Remove the lower output shaft bushing retaining ring (12b) and lower output
shaft bushing (5).
