CHECKING THE ROCKER ARMS AND
ROCKER ARM SHAFTS
The following procedure applies to all of the
rocker arms and rocker arm shafts.
1. Check:
• Rocker arm
Damage/wear → Replace.
2. Check:
• Rocker arm shaft
Blue discoloration/excessive wear/pit-
ting/scratches → Replace or check the lubri-
cation system.
3. Measure:
• Rocker arm inside diameter
Out of specification → Replace.
4. Measure:
• Rocker arm shaft outside diameter
Out of specification → Replace.
5. Calculate:
• Rocker-arm-to-rocker-arm-shaft clearance
Out of specification → Replace the defective
part(s).
IP
Calculate the clearance by subtracting the rock-
er arm shaft outside diameter from the rocker
arm inside diameter.
