Cylinder Head Removal
[213 EV]
If the engine is not being completely
disassembled for overhaul and only the cylinder
head is to be removed, the six screws A and C
which secure the timing gear plate to the cylinder
head and the three upper screws B securing the
idler gear hub to the cylinder head MUST BE
REMOVED (Figure 180). Failure to do so may
result in severe damage to the cylinder head and
other engine components as the cylinder head is
removed. See “REMOVING THE TIMING GEAR
PLATE-TO-CYLINDER HEAD SCREWS” on
page 143.
