from falling.

• Incline the spring retainer 

2

 and set it into the valve stem

groove.

• Apply engine oil to the rocker arm shaft 

3

.

• Install the rocker arm shaft 

3

.

• Install the new O-rings 

4

 to the intake pipe 

5

 and insulator

6

ROCKER ARM PUSH ROD

INSPECTION

Inspect the rocker arm push rods for abnormal wear, damage or
bend.
If any abnormal condition is found, replace the push rod with a
new one.

Make sure that the spring retainer fits snugly into the
groove 

A

 on the valve stem end.

The removed O-rings must be replaced to prevent air
from sucking through the joint.
