Giulietta Sprint 101 1300 engine rebuild part 5: Waterpump

Another pretty part ready for installation.  As with just about everything else relating to this 101 1300 rebuild, the waterpump is not just an off the shelf purchased part that gets to be bolted on.  Theoretically the waterpump is an owner servicable part and rebuild kits are available, but years in a hostile environment means the average, or even above average DIY Alfa owner is going to need help.

I pressed the impeller out of the bearings and found it to be in good shape with little corrosion or wear on the bearing and sealing surfaces.  Once the impeller was out I removed the snap ring that positioned the outer bearing and that is where I got hung up.  I wasn’t sure which way to try and press the bearings out and the special seal with the toleranced mounting flange and spring was all corroded.  At this point I decided I could irrepairably damage the pump if I wasn’t careful so I put all the parts in a plastic bag and delivered it, along with my rod bearings to John Norman Racing where Dan Marvin rebuilt it.

How much did the rebuild cost?  The parts were about $40, not sure yet how much the labor will be as I will be paying the a few bills at the same time.  Look for a post about connecting rod small end bushings and 1750 waterpump installation in the daily Berlina.
