Abstract
A retrofit kit for enabling an inline four cylinder automobile internal combustion engine to operate following removal of its upper and lower balance shafts. The includes a first bushing having a smooth circular cylindrical outer surface sized to permit close-fitting insertion into an oil-receiving bore that houses an upper balance shaft,and thereby interrupting the flow of oil to said bore, a second bushing having a smooth circular cylindrical outer surface sized to permit close-fitting interaction with an oil pump in a manner to interrupt oil flow to an oil-receiving bore that houses a lower balance shaft, and a replacement endless roller chain sized to extend interactively between the oil pump and the crankshaft of the engine.
Claims4
A retrofit kit for enabling an inline four cylinder automotive internal combustion engine to operate following removal of its upper and lower balance shafts, said engine further comprising an engine block having a front surface, a crankshaft;
- penetrating said front surface, and an oil pump mounted upon said front;
- surface, said balance shafts being rotatively positioned within oil-receiving bores that forwardly terminate in said front surface, said kit comprising:
- a) a first bushing having a smooth circular cylindrical outer surface sized to permit close-fitting insertion into the forward extremity of the bore for said upper balance shaft, thereby interrupting oil flow to said bore,
- b) a second bushing having a smooth circular cylindrical outer surface sized to permit close-fitting interaction with said oil pump in a manner to interrupt oil flow to the bore for said lower balance shaft, and
- c) a replacement endless roller chain sized to extend between said oil pump and crankshaft, thereby conveying rotational driving force from said crankshaft to said oil pump.
