Its important to take some info, and or older documents with a grain of salt, as well updated parts to solve old problems have issues as well, typically with  quality control, or the lack of it.


There are two options for a inserted water pump, Burton and Bean, but a properly rebuilt original pump with modern bearing and seal is quite dependable.  Run a bit of water soluble oil keeps the face seal from sticking.

Belt tension doesn't seem to bother the current pump bearing, but rather higher racing rpm.
