Why do you need to rotate the crank shaft, also is this a preventative measure, and is this a procedure that is performed on a scheduled basis? Thank you for all of y’all’s great videos I have learned a lot and want to learn more
Thanks for the great video!! Glad I have something to refer to when diving into one of our HF pumps - which isn't too often. Well done! When will the WK530 pump have a video? We have quite a few all of the world now so that would be useful. Thanks! Dan from Tuscatube.com
Can anyone tell me if the same process & tools are needed/available for an A.V. pump of similar build & specs.(any shop in the mountain west recommendation?) My local pump guy said he needed to tear down the crank case to redo the oil seals from the inside. While I hate to buy new when something can be rebuilt, it does not make sense to spend $150 on rebuild when a new one is $180.
those are custom made tools by them, they sell them for an obsurd price, like 150€ each. So you'll save money doing without it unless you fix 10 pumps/day. You can pull the seal with a screw to remoove it (it will kill the seal but we are changing it anyway) there is videos on youtube explaining how to remoove this type of seals.
