[213 LH] VALVE LIFTER PUSH
RODS
Inspection
Check the push rods. Replace any push rods that
have loose ends, are bent, or show signs of
excessive wear.
Identification
Refer to Figure 6-67.
The current E7 valve lifter has no hole in the
center of the stem. In conjunction with this
change, the E7 inlet and exhaust (nonbrake
engine) push rods have a 0.060-inch (1.524 mm)
maximum flat or dimple on the ball end. The push
rod part number is etched or roll-stamped on the
push rod.
The non-current push rod should be used only
with the non-current lifter. If the non-current push
rod with the wide flat or dimple is used in the
current valve lifter which has no center hole, it
may create an undesirable wear pattern in the
lifter socket.
Mixing current and non-current valve lifters is
permissible when using the correct lifter/push rod
combination.
앫 Current push rod can be used with either
valve lifter.
앫 Do not use non-current valve lifter to service
current valve lifter.
Only Dynatard exhaust push rods are not
affected and can be used with current and non-
current valve lifters. Dynatard intake push rods
still need to be updated to current push rods
when using current valve lifters.
