[Mgb-v8] I see the light!! (shortened water pump)

[Carl Floyd]

Barrie,

I would be interested depending on price & pump used. I much prefer the Buick
300 water pump.

Also, I would be looking for a 1" shallower water pump pulley. That, to me,
would be preferable to moving the other two. Plus, my Delco alternator is
already against the valve cover.

  Folks of MG persuasion

  Carl is right - no mention was made stating that the plane remained the
same.  It was said that the pulley remains the same - this is NOT the same as
the plane.   If one looks at the picture at
http://www.britishv8.org/Articles/Shortie-Water-Pump.htm you will see that
body was cut down and "re-bearinged".  Then the shaft was shortened and the
pulley mount thing refitted.  So to be certain we all understand - these are
the details


  Engine is bog standard Rover 3.5L V8
  Engine mounts are Towery A/C

  Standard P591 water pump from Canadian Tire
  Water pump body cut back at pulley side
  New bearing inserted in new cut back position
  Shaft shortened
  Pulley mount refitted

  RESULT

  Overall length changed from 4" to 3"
  Will accept SAME pulley as before
  Belt plane now 1" closer to engine
  Requires 1" shortened crank pulley (Buick or SD1)
  Requires alternator to be moved back 1" (trivial!)


  However, one point has been consistently ignored and that is it has been
done and IT WORKS (approx 10K kilometres)  I have taken photos of the crank
pulley and alternator/belt setup and if anyone wants them I will send.

    Still looking for that reference.

      <<Here's a pic of Barrie's engine with the shortened pump:

      Compare that with the offset on Mike Moor's water pump pulley:

      Dave is right in that originally it was stated that no change in either
    pulley was needed.

      However, Carl's pictures have cleared the entire mess up -- at least for
me.
    I can see from the two pictures that the actual plane remains the same in
the
    modification and therefore the pump pulley is in alignment with the crank
    pulley. The difference is in how far forward the remainder of the pump
sits in
    its original configuration.

      Overall, a very nice savings allowing much needed space. Thanks again
to
    Carl for those pictures and to Barrie for "gettin er done."

      Darius
