15. IN CRADLE ENGINE SERVICE
NOTE: Basic maintenance, valve adjustment,
and fuel system repair can be easily accom-
plished without removing the engine from the
vehicle. Any repair that requires the fan cover to
be completely removed from the engine is most
easily performed on the bench, with the engine
removed from the vehicle. Fuel pump service
and valve lash adjustment are two typical proce-
dures that can be performed with the engine in
place.
FUEL PUMP SERVICE
It may be necessary to replace the fuel pump if the fol-
lowing situations exist:
• Fuel pump pressure is less than .5 PSI, and
other factors are eliminated: pinched line, leaky
pick-up, blocked filter, loss of vacuum to pump.
• The fuel pump diaphragm has failed, causing
fuel to enter the crankcase.
NOTE: Fuel pump performance may be checked
without removing the pump.
15.1. Park the vehicle on firm level ground, and raise
the bed to gain access to the engine.
15.2. Lift the four clips that secure the air filter cover.
Remove the cover, pre-filter, and filter.
See Figure 15.2.
15.3. Remove the two screws holding the air filter
base to the fan cover using an 8mm driver.
Remove the two screws that hold the air filter
base to the carburetor using a 10 mm driver.
See Figure 15.3.
NOTE: The fan side of the air filter base is also
located by a bracket and rubber grommet.
15.4. Remove the four nuts securing the finger guard
using a 10 mm wrench. Remove the finger
guard.
15.5. Remove the two phillips head screws that hold
the fuel pump cover in place. Move the cover
out of the way, along with the hoses, tubes, and
wires that are secured to it with cable ties.
See Figure 15.5.
