3. Generously coat with clean petroleum jelly two
“zero” thrust races, and a new needle thrust bearing.
Assemble races and bearing to front end of shaft and
plate assembly and insert assembly into front
cylinder ‘(see Figure
8. Repeat preceding step for reassembly of pistons
No. “2” and No. “3”.
9. Reassemble rear cylinder onto front cylinder
ing wood block and mallet (see Figure
4. Assemble two additional “zero” thrust races and
a new needle thrust bearing to rear end of shaft and
plate assembly.
5. Lightly coat ball pockets of the three pistons with
clean petroleum jelly and place a piston drive ball in
each pocket.
6. Lightly coat the three “zero” shoe discs with
clean petroleum jelly and place a disc on only the
piston drive ball at the front of each piston.
Do not place shoe discs on rear piston drive balls. Do
not reassemble piston rings on pistons (if service pis-
tons) at this time. Use lubricant in
quantity
so that piston drive balls and shoe discs stick to
p i s t o n .
7. Rotate shaft and plate assembly until high
point of wash plate is over No. “1” cylinder bore.
Position No. “1” piston onto
plate (see Figure
and lower the piston and plate so the
front end (notched end see Figure of the
piston enters the cylinder bore.
In the piston onto the plate, the
shaft and plate assembly must be raised ap-
proximately inch, and also the front needle
thrust and races must be held up against the
hub of the plate.

10. Remove cylinder assembly from on top of com-
pressing fixture (J-9397), position assembly inside
fixture so that discharge tube opening in cylinder
halves is located between fixture legs, and front of
cylinder assembly is downward. Install and torque
fixture nuts to 15 lb. ft.
11. Gage piston play as follows:
