Disassembly and Assembly
Place the end cap gasket on the housing, being
certain the locating pins are in place, then install
the end cap and valve plate. Hold the valve plate
so it does not drop off during assembly. The end
cap and gasket will only align with housing
mounting holes in one position.
In order to replace the cylinder block unit, the
shaft seal
(page 17)
, the valve block
(page 19)
and
the end cap
(page 22)
, must first be removed.
The tapered bearing must now be removed from
the shaft. A bearing puller should be used that
will pull against the inner race of bearing. Protect
the cylinder block face during this operation.
Install two (2) end cap screws and alter nately
tighten them until the internal spring has
compressed far enough for the end cap to rest
on the housing. Install the remaining screws.
Install the shaft seal and valve manifold as
outlined in the minor repair procedu res.
After removal of the bearing, slip the spacer out
of the bore in the cylinder block.
