NOTE: The roller pin must be installed correctly to make sure the cam follower roller and the roller pin are supplied
with oil. Inspect the new roller pin as shown to determine the oil feed pass (1) and the alignment hole (2) locations. The oil feed passage is drilled approximately two-thirds of the way through the pin. The alignment hole is drilled completely through the pin.
Use a grease pencil or a similar marker to draw a line on the side of the roller pin that is perpendicular to the
alignment hole.
NOTE: The line will help align the roller pin correctly in the cam follower lever.
Install the cam follower lever in an arbor press with the leg with the alignment hole towards the top.
Install the roller into the cam follower lever.
Caution: Use the largest feeler gauge that will fit between the roller and the lever to prevent leg deflection
when installing the roller pin. This will reduce shaving of the bronze roller pin and prevent leg breakage.
Install a feeler gauge between the roller and the leg of the lever.
• Valve cam follower lever (A)
• Injector cam follower lever (B)
Caution: The cam follower roller pin must be installed with the oil feed hole (1) positioned towards the top of
the cam follower lever (2).
NOTE: Freezing the roller pin will simplify its installation.
Use clean 15W-40 oil to lubricate the roller pin.
Install the roller pin. Make sure the pin alignment hole (1) is correctly aligned with the alignment hole (2) in the lever
before pushing the roller pin into the cam follower lever.
Install a new roll pin into the cam follower lever.
Drive the roll pin in until it is approximately 1.5 mm [0.06-inch] below the surface of the cam follower lever.
Turn the roller by hand to make sure it rotates freely.
Measure the cam follower roller side clearance.
NOTE: If the roller does not rotate freely or the clearance is not within specification, disassemble and check the roller
pin and the lever for damage. The pin can not be used again.
