HD800 water pump impeller

toolz · Nov 27, 2013

I have a puller with an HD800 running around 3000 rpm. I've been told by a couple of sources to remove half of the impeller blades to reduce HP loss, and to reduce water pressure at high rpm. I've never operated on an HD800 water pump- how is the impeller attached to the shaft, and how is it removed?

Your not losing that much from a water pump! If your worried about it that much put a electric pump on it

If you"re running a smaller radiator it will churn the water pretty bad with the stock one. I doubt you"re loosing much horsepower but it can make for poor cooling. We"re running an aluminum IH radiator with the stock water pump and it cools ok but can get pretty warm on those 100 degree days back to back pulling. Wouldn"t hurt anything to remove some of the fins.

I guess I gave a bit too much information. Let me re-phrase the question.

How is the impeller attached to the shaft, and how is it removed?

Thanks for your help.
