Content-Type: text/plain; format=flowed

bentley says a lot of things that really dont have much validity. like not using a click-type torque wrench on the heads. why not? there's no solid explanation. i dont see any reason why reversing a pump could damage it. i've tried it and it works. hitting it with a hammer also works.
