DESCRIPTION & OPERATION
Do not interchange yokes. If an E-Tech™
yoke
is
used on an earlier E7 engine, the valve keepers
will become dislodged and cause a dropped
valve. This will cause severe engine damage. If
the E7 yoke is used on an exhaust location of a
J-Tech™
brake-equipped
E-Tech™
engine,
the
yoke will disengage from the valve stem tip during
engine brake operation. See Figure 31.
