In order to tit the piston onto the plate and
into the cylinder bore, the plate must be raised
approximately inch, the front needle thrust bear-
ing and races must be held up against the hub of the
plate, and the service piston rings must be
squeezed together (see Figure Lubricate
cylinder bore, piston assembly and wash plate with
No. 525 viscosity oil to facilitate reassembly.
4. Repeat procedure in Steps 1 and 2 for installation
of No. 2 and No. 3 pistons.
5. Obtain new service replacement discharge tube
and assemble into front cylinder (see Figure

6. Liberally lubricate cylinder bores of rear cylinder
with No. 525 viscosity oil and reassemble rear cylin-
der onto front cylinder being sure to compress ser-
vice piston rings. Align discharge tube and dowel
pins, and tap cylinder halves together. Check for free
rotation of shaft.
If are positioned in a “stair-step” arrange-
ment (see Figure installation of rear cylin-
der will be facilitated. In addition once the service
piston and ring are started into the cylinder, slight
rotation of the shaft to and fro will work the ring into
the bore.
