Unscrew the remaining 3 screws using the

combination wrench and turn each screw a

couple of rounds at the time, to ensure the

swash plate is loosened as straight

backwards as possible.

Note: There is nothing to hold the swash plate!

Remove the flange/swash plate carefully.

Place the swash plate upside down to avoid

scratches on the surface.

Carefully remove the pistons one by one.
