Inspect Bridges and Push Tubes
A—Valve Bridge
B—Valve Stems
C—Push Tube
IMPORTANT: Thoroughly inspect intake and exhaust
valve bridges (A) for proper seating on
valve stems (B) from both sides of
engine. Also, make sure that push
tubes (C) are properly seated in top of
valve bridges.
Use a flashlight and carefully check
each bridge (for proper seating on valve
stems) from both sides of the engine.
Lift up on each bridge to verify proper
seating. Valve bridges that are not
properly seated on valve stems will
result in major engine failure.
Before installing rocker arm cover,
make sure that all EUI wires are
positioned so that rocker arm will not
contact wires when engine is running.
4. Install rocker arm cover. (See REMOVE AND INSTALL
ROCKER ARM COVER, earlier in this group.)
