Changing the cylinder block kit (disassembly)
After removal of the bearing, slip the spacer out
of the bore of the cylinder block.
Depending upon the extent of damage, the
cylinder block assembly should be either
completely, or partly, replaced. Any individual
part can be changed as may be necessary.
In order to change the cylinder block assembly,
the shaft seal must first be removed
(page 19)
as
well as the charge pump
(page 21 and 22)
and the
end cap
(page 24 and 25)
. The bearing can then
be removed from the shaft with a bearing puller.
A spacer is required to protect the slot in the end
of the pump shaft from the puller screw. When
doing this, great care must be exercised to
ensure that the bearing casing is not damaged.
The cylin der block surfaces must be protected.
Place the pump horizontally in repara tion for
removal of the cylinder block assembly. Slide the
cylinder block assembly off the shaft while
holding the external end of the shaft.
