Title: Engine rotation
Post by: jonboy on July 15, 2015, 02:13:26 PM
Hello group I'm looking at old greyhound buses with the 6-71 Detroit Diesel engine. I'm looking for a water pump to replace the leaking one on the bus. Does any one know the rotation is it a left or right, it makes a difference.

Thanks for any help, jonboy

Isn't the water pump driven directly off the cam, and doesn't the cam rotate the same way regardless of the rotation of the crankshaft?
