Clean outside of pump thoroughly.
Mark the Pump sections on the side
nearest to the drive shaft exten-
sion so that they can be reassembled
back to the original relationship.
(Figure 44)
Place pump in machinist vise
securely, shaft up, using a clean
block of wood between the flats on
each side and the jaws of the vise.
This keeps fror marring the machined
surface of the pump and causing
leakage at the port connectors.

HYDRAULIC PUMP
Disassembly
Remove nuts (23) and washers from
studs.
Remove pump from vise and set pump
on bench with shaft end up. Coat
the shaft extension with clean
grease. This will help to keep
from damaging the rubber sealing
surface of shaft seal when seal is
removed.
Lift the flange (4) off the pump,
keeping the flange as straight as
possible during removal. If the
flange is stuck, use a wood mallet
or plastic hammer and tap around
the edge to loosen it. (Figure 46)
