Impeller Puller for 40-65 mm

I have the big one that I bought here for an emergency years ago. I had forgotten the price, I see it right here, definitely an insolence. Now I needed him for the first time. My pump is sitting quite angled (Volvo Penta MD50A) No chance to use the puller. Apparently, no thought was given to constructing the outer, slim \ '. (eg the silly T-handle on the screw) So the whole pump is dismantled. Now I'm trying to use the puller. Again there is no indication, the plastic wings of the clamping screws collide with the pump housing. So the two clamping screws were replaced by normal M6 hexagon screws. Next experience, the puller does not reach behind the impeller, as the photos suggest (since the impeller rests on the rear wall (wear plate) of the housing, the tines should have been chamfered from the other side), but bored in the impeller rubber. Although I tightened my M6 screws with the pliers, the tines pull clearly visible grooves in the rubber before the impeller starts to slide. The impeller is damaged where the tines grip. (Sure, it is usually anyway, but for me it was exceptionally brand new because I had changed it before, but now I needed it somewhere else.) So what had worked just before when changing the impeller (but unfortunately not always) ): Remove the cover and start the machine. By turning the impeller had worked out in a flash and a lot in the bilge ..... My judgment: unusable.
