supplies suitable to collect and contain fluids in Caterpillar
machines. Dispose of fluids according to local regulations and
Remove two O-ring seals (1) from the rear cover of the

Using a suitable size drive plate from Tool (A) and a
press, push the shaft and pulley (3), as a unit, out of
impeller (4). Remove the impeller.
Do not allow the shaft and pulley to fall to the floor as it is
being removed from seal (5) and the water pump housing.
