Camshaft Bushing Cummins Engine ISL – Engine QSL
Camshaft Bearing Cummins Engine ISL – Engine QSL
It is pressed into the engine block and supports the camshaft during rotation. It maintains the correct alignment of the camshaft, reduces friction and wear between the camshaft and the block, and helps maintain the correct clearance and lubrication of the bearing.
It is primarily used in the Cummins C Series 8.3 L family, including the 6C, 6CT, and 6CTA models, and is also recommended by specialized distributors for ISC, QSC, ISL, and QSL applications.
Before the sale or installation, I recommend checking the ESN (Engine Serial Number), CPL, and Parts Catalog/QuickServe, because even within the same engine family, there may be variations in configuration and model year.

Rocker Arm Assembly Cummins Engine ISL – Engine QSL
Rocker Lever Assembly Cummins Engine ISL – Engine QSL
The rocker arm is part of the valve train. It receives motion from the camshaft via the rocker arm and pushrod and transfers it to the valves, enabling the intake and exhaust valves to open and close properly. It thus maintains proper synchronization between the valve train and cylinder operation.
Compatible Engines: Cummins 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9, QSL9.
However, I recommend checking the ESN (Engine Serial Number), CPL, and engine configuration, because within the 6C family, there may be different rocker arm variants depending on the model year and cylinder head configuration.
