To all,
For what it is worth, I am with Darius. It seems to me that
either this short pump will require a pulley with a different amount
of offset, or the other pulleys in the system will also need to be
changed to match. All pulley grooves for a single belt must lie in
the same plane. I even wonder if the short pump might locate the fan
in the old belt plane?? Or maybe awfully close? Am I missing
something here also???
Cheers,
Dave K.
