To install the cylinder block assembly it is necessary to
check the alignment of certain parts. There is no
special relationship of pistons to bores, springs, etc.
However, the alignment of the ball guide and cylinder
block splines iscritical. The undersized tooth in the
spline of the cylinder block must line up with the missing
tooth in the ball guide spline.
These in turn line up with a missing tooth on the shaft
spline. The hole for the bearing plate locating pin in the
cylinder block face is in line with the undersize tooth in
the cylinder block and provides an assembly guide.
Lubricate the swashplate, slippers, pistons and bores
with clean hydraulic oil. Hold the shaft on the external
end, align the missing shaft tooth with the missing ball
guide tooth using the locating pin hole as a guide. Slide
the cylinder block assembly onto shaft and against
swashplate face. When properly installed a spring load
can be felt when pushing against the cylinder block.
Set the motor vertically and install the spacer in the
center bore of the cylinder block.
