J<br />
pump body and pulley result in a very limited<br />
clearance between these components so that the<br />
labyrinth sealing effect obtained offers increased<br />
restriction to the passage of dust to the water pump<br />
front bearing.<br />
Since the width of the pump bearings have been<br />
increased, a shorter distance piece is now fttted<br />
between the bearings, and the increased bearing<br />
diameter necessitates the use of a larger front<br />
bearing retaining circlip.<br />
Q3<br />
A modification to the impeller shaft dispenses<br />
with the thrower flan ge previously fitted at the rear<br />
of the front seal and self-locking nut replaces the<br />
retaining slotted nut and split pin previously fitted<br />
to retain the water pump pulley.<br />
The process of dismantling and reassembly uf<br />
the water pump as detailed previously is applicable<br />
to the latest type pump with the exception of those<br />
remarks in respect of the thrower flange and<br />
slotted pulley retaining nut and split pin.
