    Default Long Stroke Water Pump Upgrade

    I found that the ceramic seat from a Chinese KY Model 108-15 shaft seal (ordered from Amazon) was a perfect fit for the 1911cc water pump, so I counterbored the pump housing 27.0 Ī 0.1 mm x 5mm deep and installed the seat. Now the water pump seal will run on a ceramic seat instead of the raw aluminum. It should now be leak-free for many miles. (The measurements written on the body are so I can calculate the thickness of the spacers under the seal to get the correct compression.)

    That is brilliant. Would probably work for the pumps on the later 11 'Perfo' engines as well! The seals on those engines are the same as a 1911 D engine but they run onto the cast iron of the pump!
