between rocker arm socket and crosshead. Ensure valve clearance is
within specification. See VALVE CLEARANCE SPECIFICATIONS table. If
valve clearance is within specification, go to next step. If any valve
clearance is not within specification, loosen rocker lever adjusting
screw lock nut, and adjust valve clearance by rotating rocker lever
adjusting screw. Tighten rocker lever adjusting screw lock nut to
specification. See TORQUE SPECIFICATIONS. When all valve clearances
are within specification, go to next step.

FUEL INJECTION PUMP TIMING
CHECKING FUEL INJECTION PUMP TIMING
NOTE: With Bosch VP 44 pump, no mechanical adjustments are
necessary. All timing and fuel adjustments are performed by
Engine Control Module (ECM). If a FTC indicating engine sync
error or static timing error has been set, perform following
adjustment. If FTC sets after installing a new pump, pump
keyway has probably been installed backward.
CAUTION: DO NOT allow nut and washer to fall inside front cover.
1) Remove fuel pump access cover, shaft nut and washer.
Ensure keyway aligning pump shaft to pump gear has not slipped. If
keyway has slipped, repair as necessary.
2) Remove timing gear cover. See REMOVAL, OVERHAUL &
INSTALLATION - TRUCKS - DIESEL article. Using a T-type puller, remove
injection pump gear from shaft. Ensure key has been installed in
keyway with arrow pointing to rear of pump. Pump timing is calibrated
to pump keyway. Ensure 3-digit number on key matches number on pump

CAUTION: When removing a deployed air bag, wear eye protection, rubber
gloves and a long-sleeve shirt. Powder residue from air bag
deployment may irritate skin and eyes.
CAUTION: Before removing steering wheel, position front wheels in
straight-ahead position and lock steering column by removing
ignition key. Failure to do so could damage clockspring or
cause clockspring to be off-centered. DO NOT hammer on
steering wheel during removal, or collapsible column could be
damaged.
