Remove the three hex head bolts that hold the trunnion
to the motor
The trunnion fits into the motor tightly; use a slide
hammer to loosen it. Screw the slide hammer into the

Remove the trunnions and shims.
Important: Keep the shims with each trunnion; they
must be reinstalled on the same trunnion during
reassembly. The shims pre-load the trunnion bearings.
Remove the o-ring from the trunnion, see figure 19.
49 If the trunnion bearings are damaged replace them.
A split blade bearing puller will be needed to remove the
bearing cone from the trunnion. Use a press to install
the new bearing cone.
50 Carefully remove the swashplate, cylinder barrel and
shaft through the mounting flange end of the housing.
