My Triumph consistenly runs warm and I would like it to flow a bit more water. The vanes on the impeller are minisule compared to other water pumps with similiar displacement engines. In the image the
2.0 / 2.5L engine displacement Triumph water pump with impeller is on the left and the proposed donor impeller (from an Isuzu 2.3L) is on the right.In trying to dismantle the two pumps, there is inadequate room to get a bearing seperator between the impeller and the pump housing on either pump. My thought is to remove the pressed on fan mounting flange and then press the shaft (with impeller attached) out of the pump housing. I got the pressed on fan mounting flange off of the Isuzu water pump but did not succeeded in pressing the shaft out of the housing (watching the deflection of the press and the increasing effort on the jack hande, I stopped adding force). I have a "30 Ton" Harbor Freight A-frame press that I suspect is capable of about 20T. Does my proposal in dismantling sound wrong? I can cut the Isuzu pump body apart if needed.
