Roller Rocker Arm

Now available from Wesco Valve & Manufacturing Company, our new Roller Arm: replaces the OEM Rocker Arm on all Clark BA and HBA engines with absolutely no modification. The durable aluminum casting is stronger than the conventional cast-iron rocker arm, and carries a lifetime guarantee against breakage under normal working conditions. Aluminum roller rocker arms are also available for Clark HRA/RA (new style) as well as Cooper-Bessemer GMV Engines.

The unique roller design eliminates valve stem flexing, extends fuel valve stem life , minimizes alignment problems, and significantly reduces rocker arm maintenance. Roller arms come complete with needle bearings, and hardened steel pin. Repair parts can be purchased in a kit or the rocker arm may be shipped to our manufacturing facility in Marshall, TX on an exchange basis.
