2088266 9205345 PCTABS00011 The design and construction of past pushrod retainers have required complex components, sliding relationships and additional assembly time and expense. The present invention overcomes these problems by using a retention shelf (144) attached to a cylinder block (14). Thus, the components are simple to install, inexpensive to manufacture and do not increase assembly time since there is no adjustment necessary when using the device. The present retention shelf assemblies (142) provide a device which prevents extensive damage to the engine (12) caused by a large separation between the cupped end (96) of the pushrod (94) and the first end (50) of the rocker arm (46) which allows the pushrod (94) to fall into other components, resulting in malfunction of the engine (12). The device is preassembled to the cylinder block (14) and requires no additional assembly time or alignment when assembling the engine (12). The device is inexpensive to manufacture and prevents the pushrod (94) from causing damage to the engine (12) should the first end (50) of the rocker arm (46) not be moved to the second operating position (84) causing the pushrod (94) to become free or disconnected.
