or spilled fuel can ignite. if any fuel is
spilled, make
sure the area is dry before start-
ing the engine.
1. Fuel speclflcatlons. Use automotive gasoline with a
pump octane number
of 86 or higher. If the engine
knocks
or pings, use a higher octaine gasoline. Un-

NOTE: Soak the packings in oil, and coat the rod and

NOTE: Alternate leather and plastic packings as
shown in Fig 18-3.
Be sure the lips of the v-

installation damages the packings and results
in pump leakage.
1. Check the piston rod (224) and the inside of the sleeve

Warning on page 13 before repairing
NOTE Steps 1 to 13 refer to Fig 20-1, '
1. Refer to Rernovlng the Pump on page 18.
2. Remove the four screws (73) and lockwash-
ers
(74) from the bearing housing.
3. While pulling the connecting rod
(22) with
one hand, lightly tap the lower rear of the
bearing housing (21) with a plastic mallet to
loosen it from the drive housing (20). Pull the
bearing housing and the connecting rod as-
sembly
(22) off the drive housing.
4. Inspect the crank (A) for excessive wear and
replace parts as needed.
5. Evenly lubricate the inside of the bronze
bearing (C)
in the bearing housing (21), and
the inside of the connecting rod link
(D), with
high-qualitymotor oil. Liberallypack the roll-
er bearing
(E) in the connecting rod assem-
biy (22) with bearing grease.
6. Assemble the connecting rod (22) and bear-
ing housing (21).
7. Clean the mating surfaces of the bearing and
drive housings.
8. Align the connecting rod with the crank (A)
and carefully align the locating pins
(F) in the
drive housing (20) with
me holes in the bear-
ing housing (21). Push the bearing housing
onto the drive housing ortap it into place with
a plastic mallet.
1"CAUTlON
DO NOT use the bearing housing screw
(73) to align or seat the bearing housing
with the drive housing.
These parts must be
aligned using the locating pins
(F), to help
avoid premature bearing wear.
9. Install the screws (73) and lockwashers (74)
on the bearing housing. Tighten the screws
evenly
to 175 in-lb (20 Nm).
