New Rocker Arms Are Used on C27 and C32 Commercial Engines {1123}
- Engine:
- C27 All
- C32 All
Description of Change: The new rocker arms have a coated pin that provides less friction at the roller and pin contact area. This reduced friction decreases the stress between the roller and the camshaft lobe.
Adaptable To: The new rocker arms replace the existing rocker arms. The new rocker arms are adaptable back to first production on C27 and C32 Commercial Engines. Refer to Table 1 for a list of the new part numbers and the part numbers being replaced.
