The pumps do not contain a "bearing". It is a babbit
type bushing. It has a rotary scroll type groove and
is lubricated by hyd. fluid from the rear. These do
wear, especially where excessive belt tension has been
applied. I have mulled having the casting machined to
accept a thin needle type roller bearing, but have
defaulted to using other pump bodies with bushing that
don't show much/any wear. I'm not sure if any/which
rebuilders replace the bushing or if they just screen
the core bodies as I do for low bushing wear.
