[WPTA] Water pump TR3

[John Styduhar]

Looks like you purchased the uprated water pump.  Like Vic mentioned, the
pulley is held on with a nylock nut (and maybe a flat washer).  The pulley
is also keyed on the shaft, so you must align the woodruff key in the shaft
with the broached slot in the pulley hole.   Make sure the key is fully
seated and not tipped (which could prevent the pulley from fully
engaging).  As Vic suggested, remove the pulley from the new pump and
install the long bolt.   Position the pulley on the shaft to engage the
woodruff key.  Seat the pulley on the shaft which should expose the threads
and secure the fastener.  If there is room in front of the engine, the
pulley can be installed after the water pump is mounted.  Make sure the
pump is oriented correctly on the pump housing so the weep hole is facing
downward.   P.S. don't hold the waterpump in a vice by the impeller.
