The repairs should be pretty straight foward.

Once you have the pump off you will remove the face plate, then push the
shaft coupling in until you can get to the impellor securing screw or pin
(it's usually a small/long allen). Once this screw is removed, you can push
the shaft out the other way..

You will have to find some form of drift to knock the old seals out.. A
wooden dowel works find.. You can also us a larger wooden dowel to press the
new seals in..

The water seal will have the rubber lip pointing towards the impeller and
the oil seal lip will point towards the engine side.

Before you install the shaft, look for nicks or burrs that could cut or
damage the seals. Look closely around the area of the impellor screw
threads. Sometime a burr will raise from that hole. Put some oil or water
pump grease on the shaft as you insert it.

Once the shaft is installed, assemble the impellor onto the shaft and secure
with the screw..
Put a little grease of water on the impellor as you push it back into the
pump cavity. Bend the vanes in the proper direction (if you remember from
when you removed it). Not a big deal with a new pliable impellor, on an old
impellor the vanes could break off if force in the wrong direction.

Install the pump cover plate with a new gasket (if supplied) but a little
grease helps to insure a good seal.

Before you install the pump, check that the weep hole between the seal areas
is open. Probe it with a tooth pick .. Sometimes people plug this hole when
they see water dripping out.. if it's plugged, water can get into the oil..

I recommend you download the Zip file since the .pdf file has been causing
problems when trying to veiw online.
