9Y1741 Rocker Arms for Caterpillar Equipment

The 9Y1741 rocker arm is a valve-train component used with camshaft-driven tappets to actuate engine valves in Caterpillar equipment. It is used on Caterpillar engines installed in machines and generator sets. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The rocker arm transfers movement from the valve-train mechanism to the valve. During engine operation, this movement controls the opening and closing of the intake and exhaust valves, allowing the air-fuel charge to enter the combustion chamber and exhaust gases to leave it. The part is identified by the Caterpillar equipment part number format 9Y-1741 and the compact SKU format 9Y1741.
