<p>PRE-OILING KIT FOR AN INTERNAL COMBUSTION ENGINE A pre-oiling kit for an installation having a battery, an ignition switch, an internal combustion engine, an engine block and oil sump underlying the block, a port within the block leading to an oil gallery and a drain opening within the bottom of the sump, includes as a principal element of the kit a container for mounting exterior of the block and housing a pre-oiler pump with an electric motor operatively coupled thereto, an oil pressure operated switch and an electrical relay. Two oil lines lead to the exterior of the container and are respectively connected to the inlet side of the pump through a strainer and from the outlet side of the pump through a check valve pressure switch and strainer. Four electrical lines extend from the kit container for respective connection to the ignition switch for energization of the relay through the oil pressure operated switch, a dashboard booster button, a normally open switch for connection in parallel with the oil pressure operated switch for continued manual operation and control of the pump drive motor to increase pressure to the gallery if needed, a signal light indicating operation of the pre-oiling pump and through the normally open switch contacts of the relay to the electrical source for energization of the pump motor in response to relay operation. A T fitting and a replacement drain plug facilitate kit connection to the engine block and sump, respectively.</p> |
