pump body and pulley result in a very limited
clearance between these components so that the
labyrinth sealing effect obtained offers increased
restriction to the passage of dust to the water pump
front bearing.
Since the width of the pump bearings have been
increased, a shorter distance piece is now fttted
between the bearings, and the increased bearing
diameter necessitates the use of a larger front
bearing retaining circlip.
A modification to the impeller shaft dispenses
with the thrower flan ge previously fitted at the rear
of the front seal and self-locking nut replaces the
retaining slotted nut and split pin previously fitted
to retain the water pump pulley.
The process of dismantling and reassembly uf
the water pump as detailed previously is applicable
to the latest type pump with the exception of those
remarks in respect of the thrower flange and
slotted pulley retaining nut and split pin.
