different? I have the manuals and catalogs, although none is very clear
about the pump to block relationship. Is the pump a bear to extract? Will
a
good slide hammer do the trick? What about those other o rings down in
there?, do they go bad a well?

John, from your description, your water pump is shot. I believe the
likely components to fail are the *O* rings. I believe the graphite seal or
pump shaft itself are less likely to fail but they can go too.. IMHO, since
you must remove the pump to see what the problem is, it is just plain
easier and best in the long run to replace the pump as a unit instead of
trying to mess with the old one. It is a straight-forward job that is really
only time consuming. You can remove the intake manifold with the carbs
attached. Most often a slide hammer is required, however I have heard of
folks who have been lucky to remove it without the slide hammer by
levering it out. The most time consuming aspect of the job seemed to be
replacing the pump cover. You need to use feeler guages and have a
gasket with the correct thickness when putting the cover back on. Follow
the ROM carefully on this. I think the Triumph Repair Times manual
suggets this whole job takes about 4 hours, however I believe that is
optimistic for a backyard mechanic. If you have additional questions
