On a Urraco, water pump step A is to remove the engine... (Wait a minute, engine out just to get to the water pump? Yup. Comes out with the brakes, transaxle, rear suspension, get ready to use a lot of tools.)</div> <bR> <div> <IMG SRC="3368ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> There it is. A bit of corrosion stops the pump, it stops the cam belt that drives it and then the valves bend. </div> <div> Time to do the motor too. That is fairly straight forward. The pump however can easily be destroyed if you don't understand the construction.</div> <div> <IMG SRC="3388ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> <IMG SRC="33a8ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> Bit of corrosion on the shaft. It will never work with the new seal unless it's built up and then turned down to a nice polish.</div> <div> <IMG SRC="34d8ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> The manual (which the factory told me years ago never existed,)  I found one  day in  a garage sale..</div> <div> Amazing! I knew I would need it  and couldn't believe I found a nonexistant  Italian document in the bottom of a cardboard box in Walnut Creek California. At some point I will scan some of the instructions and insert them here. Anyway, the manual is very unclear on how these pieces fit together. here is a breakdown:</div> <div> <IMG SRC="3448ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> Same pieces conceptually arranged in installation order: If you try to press the shaft out without removing the circlips you will destroy the housing. The clips are very well hidden under the water and oil seals and invisible to the eye. Unless you destroy the seals and carefully remove the pieces from the housing you can never get to the circlips. Crazy design. </div> <div> <IMG SRC="3408ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> The Aluminum hub it fits in is what the manual refers to as a "compass"</div> <div> <IMG SRC="3428ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> Sliding the assembly  back in:</div> <div> <IMG SRC="3468ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> <IMG SRC="34a8ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> Motor going together..</div> <div> <IMG SRC="3488ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> Back together & running again......</div> <div> <IMG SRC="3708ae80.jpg" border=0 width="650" height="488" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <bR> </td> </tr></table></body>
