FUEL SYSTEM Injection Pump FU-63
28. (1HZand1HD-Tonly)
ADJUST PLUNGER PRE-STROKE
(a) Install SST to the fuel cut solenoid installation screw
section.
SST 09275-17010
(b) Set the dial indicator so that the tip of the dial
indicator push rod touches the upper surface of the
plunger.
(c) Rotate the drive shaft, set the plunger to BDC and set
the scale on the dial indicator to 0 mm (0 in.)
(d) Apply a few drops of light oil (diesel fuel) to the top
surface of the plunger, and when 0.1 kg/cm
2
(1.4 psi,
49 kPa) of air is applied to SST, bubbles appear on the
upper surface of the plunger.
SST 09275-17010
(e) Slowly rotate the drive shaft in the pump rotation
direction (clockwise) and read the dial indicator when
the bubbles on the top of the plunger disappear.
Pre-stroke: 0.15-0.25 mm (0.0059- 0.0098 in.)
If the pre-stroke is not as specified, replace the plunger
adjusting shim under the plunger with a different sized
shim.
HINT: If the shim is made thicker, the pre-stroke is
decreased
(f) After completing the pre-stroke adjustment, check
that dimension B is within specifications.
Dimension B: 2.8-3.2 mm (0.110-0.126 in.)
If dimension B is not within the specification, replace the
distributor head.
