16.  Retainer guide, retainer ball and retainer plate 

must be mounted in the order indicated in 

picture below.

18. Place retainer plate in cylinder barrel.

  

Note: If pistons are replaced, place new 

pistons in clean filtered water for a couple of 

minutes. Exercise piston shoes to make them 

“run” smoother.

20.  Lubricate piston shoes and swash plate with 

clean filtered water.

22. Place three bolts in mounting flange.

 

 Turn each bolt one round at a time to ensure 

mounting flange is mounted as straight 

downwards as possible. Be careful not to 

squeeze O-ring. 

21.  Remember to place the guide pin in the 

housing.

23.  Screw in the rest of the bolts and cross tighten 

all screws to a torque of 30 +/- 2 Nm.

  

Note: Screws for lifting eye are shorter than the 

rest.

17.  Ensure that retainer plate is oriented correctly, 

ie with its slant surfaces pointing downwards.

19.   Place pistons in retainingplate  and cylinder 

barrel. When pistons are placed, tilt retaining 

plate for easier placement of swash plate.

 

If swash plate has been disassembled from  

 

 

mounting flange, see page 10 for assembly of    

 

swash plate.
