I am rebuilding my oil/water pump. The only thing Im not sure about is this: If I understand the function of the pump correctly, the narrow part of the water seal turns with the gear, i.e. the narrow end should be fixed around/to the shaft of the gear.

I cant find anything about this in my Haynes manual which has probably been made before the new type of seal was implemented. Should I oil the shaft before I pull it through the water seal or should I pull it through dry? I think (from memory) that the inside of the narrow end of the seal has a blue goo inside it to fix it to the shaft.

These articles have been very helpful:

Oooops!.... Sorry for my unnecessary question. I just came back from my garage after cleaning the pump and installing the seals and pump gear. There is no blue goo inside the narrower part of the water seal. I just oiled the shaft lightly and pulled it carefully through, until the gear was properly seated.

I made a special tool to aid the assembly of the oil/water pump to the engine. Same principle as the long bolts used to slide the gearbox in to position. Cut the heads off two long 6mm bolts and installed them into opposite boltholes on the block as shown in the photos. Put the gasket seal on the pump, slided it in, put all bolts in fingertight, waited for 45 minutes and torqued it to 7 Nm. This method helps greatly to prevent smearing the gasket seal where it is not wanted. Before torquing it down I turned the engine several times to be sure to center the pump as much as possible.

I like the idea of the finger tight guide bolts, would make line-ups very easy.

I recently used the same trick to install my alternator. Made lining up the knutz a LOT easier.
