Picking up were we left off last time, with more work on the motor. This time we're looking at the top rear of the motor, where it's easier to see the cooling water return (to radiator) manifolds. At the lower corners of the picture the camshaft ends can be seen, where the original water pumps were mounted/driven. This is also a good view of the fiberglass shroud that diverts and forces cooling air from the vertical-mounted fan down through and around the cylinders. See previous update for photo of bottom of motor which illustrates where the air exits.

Front top view of the motor. Here the intake of the vertical cooling fan is clearly seen. The fan is driven by a belt off the crankshaft, and another belt from the fan drives the alternator. Directly below the fan you see the crankshaft end, with the belt pulley that runs the fan/alternator. Also now mounted on the crankshaft end is a special fixture that holds the new crank-driven water pump, the impeller for which can be seen at the forward end.

This is a better view of the disassembled water pump. The drive and impeller is at left, with the impeller housing at right. The water pump takes a suction, through a Y-fitting, from both radiators. It discharges water through two separate fittings (see photo) and is routed through separate piping to each cylinder head (entering the head at the bottom of the head - see previous update).
