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
cylinder '(see Figure 9B-137).
4. Assemble two additional "zero" thrust races and
a new needle thrust bearing to rear end of shaft and
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 sufEcient quantity
so that piston drive balls and shoe discs stick to
p i s t o n .
7. Rotate shaft and wash plate assembly until high
point of wash plate is over No. "1" cylinder bore.
