plunger assembly to make sure it moves
smoothly (sliding resistance: 4.9 N (0.5 kgf) [
1.10 lbf] or less). At the same time, check to
make sure the total rack stroke is 36 mm [ 1.42
in.].
Control rack sliding resistance

lower than the standard value, install the deflector
bolts on the pump case and tighten.
