Removal and Replacement
Before removing and dismantling the pump, check flow and
pressure. If either of these are low and cannot be corrected
at the relief valve, the pump must be renewed completely.
Renewal of components such as gears, bearings and
housing will not effect a permanent cure. If the pump output
is satisfactory but there is external leakage, the pump should
be removed and dismantled for re-sealing only.
