				Countershaft/Intermediate Shaft
			 
			Dumb question perhaps, but what is the difference between a 'countershaft' and an 'intermediate shaft'? Or are they just two names for the same thing? Thanks.

			Countershaft is a shaft placed usually in large displacement 4 cylinder engines to reduce harmonic vibrations. Our intermidiate shafts just connect the oil pump to a gear.

			From the "Dictionary of Mechanical Engineering"; 4th Edition by G.H.F Nayler (available from SAE): countershaft An intermediate shaft in a line of shafting placed between a driving and driven shaft to obtain a greater speed-ratio or where direct connection is difficult. See also gear cluster; layshaft. | ||

			OOOO...... Maybe the one I'm thinking of is the counterbalance shaft. Good call Jim.
